FIELD OF THE INVENTION
[0002] The present invention is directed to polyamine compounds, itions, and
methods, which preferably have antimicrobial or dispersing ty against a variety of
bacterial strains capable of forming biofilms. s aspects and embodiments relate
generally to polyamine compounds and to methods of preparing or using such compounds.
BACKGROUND OF THE INVENTION
[0003] Antimicrobial compounds, such as traditional antibiotics, have the ability to kill or
to retard the growth of bacteria, fungi, and other microorganisms. Some antimicrobial
compounds also are effective t viruses. crobial compounds are used in a wide
variety of clinical settings, industrial ations, food production facilities and
environmental applications all across the globe in an effort to reduce the risk of, for example,
bacterial colonization and development of e in people.
Traditional antibiotics are primarily tives or synthetic mimics of natural
compounds secreted by bacteria, plants, or fungi. These nds typically have very
specific s of action against a cell wall/membrane component of bacteria, or an
enzyme/protein in a metabolic pathway. Examples of traditional antibiotics on the market
include penicillin, oxacillin, vancomycin, gentamicin, icin and amoxicillin, among
others.
Because bacteria have the ability to develop resistance genes to these antibiotics as
a result of genetic mutations or acquired defense mechanisms that target the c activity
of the antibiotics, bacteria lly have the ability to develop resistance to traditional
antibiotics. Increasingly more prevalent bacterial resistance has made traditional antibiotics
to become less and less effective in a variety of ations.
Bacterial resistance to antibiotics represents one of the most underappreciated
s to modern y. See Zhang et al., Antibiotic resistance as a global threat: Evidence
from China, Kuwait and the United States, Global Health 2, 6 (2006). Currently, more than
90% of clinical isolates of Staphylococcus aureus display resistance to penicillin. See
Balaban et al., l ofBiofilm ions by Signal Manipulation, Ch. 1, 1-11 (Springer,
2008). Recent reports have even indicated that ia in natural ecosystems metabolize
antibiotics as an energy source. See Leslie, Germs Take a Bite Out ofAntibiotics, Science
320, 33 (2008). The trend of bacterial resistance ues to increase as indicated by almost
daily ific publications and world news reports of antibiotic resistant superbugs such as
carbapenem-resistant bacteriacea, vancomycin-resistant Enterococci, multidrug-
resistant Pseudomonas aeruginosa and methicillin—resistant Staphylococcus aureus (MRSA).
See e. g., FoxNews.com. Europe in the Grip ofDrug-Resistant Superbugs ; Melnick,
M., TIME (2010); Arias et al., The rise of the Enterococcus.‘ beyond vancomycin resistance,
Nat Rev Microbiol 10, 8 (2012); Jain, R. et al., Veterans aflairs initiative to prevent
methicillin-resistant Staphylococcus aureus infections, N Engl J Med 364, 1419-1430 (2011);

Pseudomonas aeruginosa.‘ riskfactors and clinical , Antimicrob Agents Chem 50, 43-
48 (2006). In addition to adversely affecting civilian patients, antibiotic-resistant ia
affect injured military personnel. Multiple reports from Operation Iraqi Freedom/Operation
Enduring Freedom have indicated that multidrug-resistant bacteria and otic resistance
constitute one of the most disconcerting aspects of military theater treatment. See e.g.,
Calhoun et al., Multidrug—resistant Organisms in Military Woundsfrom Iraq and
Afghanistan, Clinical Orthopaedics and Related Research 466, 1356-1362 ; Murray et
al., Bacteriology of War Wounds at the Time ofInjury, ry Medicine 171, 826—829

Acinetobacter sp. Isolatesfrom Military and Civilian Patients Treated at the Walter Reed
Army Medical Center, Antmicrobial Agents and Chemotherapy 50, 4114-4123 (2006).
Multiple factors contribute to bacterial cells’ ability to resist the s of
antibiotics. See e. g., Morita et al., Antibiotic Inducibility ofthe MexXYMultidrug Efflux

Product, Journal of Bacteriology 188, 1847-1855 (2006); Tran et al., Heat-Shock Protein

Negative Bacteria in Sepsis With a Focus on Neisseria meningitidis, Contributions to
Microbiology 17, 31-47 (2011); Nostro, et al., Specific Ion Eflects on the Growth Rates of
Staphylococus aureus ana1 Pseudomonas nosa, Physical Biology 2, 1-7 (2005).
Amongst these factors is the y of bacteria to develop a biofilm. See e. g., Costerton et al.,
How bacteria stick, Sci Am 238, 86-95 (1978); Lawrence et al., l sectioning of
microbial s, J Bacteriol 173, 6558-6567 ; ZoBell, The Eflect ofSolia1 Surfaces
upon Bacterial Activity, Journal of Bacteriology 46, 39-56 (1943). Biofilms have unique
characteristics that allow them to withstand, or defend themselves against a variety of
bations including exposure to antibiotics.
Biofilms are surface-attached ities of bacteria, often polymicrobial, that
produce a slimy, extracellular polysaccharide substance (EPS) that encapsulates them. The
EPS provides protection, Leid et al., The Exopolysacharide Alginate Protects Pseudomonas
aeruginosa Biofilm Bacteriafrom Mediated Macrophage Killing, The Journal of
Immunology 175, 7512-7518 (2005), as well as a e of nutrients, water and trace
elements to sustain life. ton et al., The Bacterial Glycocalyx in Nature and Disease,
Annual Review of Microbiology 35, 4 (1981). Biofilms are the inant
phenotype of bacteria in natural ecosystems. egative bacteria, Gram-positive
bacteria, and mycobacteria, in addition to other unicellular organisms, can produce biofilms.
Within the biofilm community, bacteria may have several methods of defending
themselves against the biocidal effects of antibiotics. First, they have strength in numbers.
Biofilms may contain millions or trillions of cells in a very small volume. Second, bacteria in
a biofilm have the ability to rapidly transfer genetic material, such as plasmids, that
specifically code for the production of les that protect them against antibiotics. Lujan
etal., Disrupting Antibiotic Resistance Propagation by Inhibiting the Conjugative DNA
Relaxase, PNAS 104, 12282—12287 ; Lederberg et al., Gene Recombination in
Escherichia coli. Nature 158, 529-564 (1946). Rates of plasmid transfer in biofilms have
been shown to be much higher than amongst planktonic bacteria, which are free-floating in
an environment. Hausner et al., High Rates ofConjugation in Bacterial Biofilms as
Determined by Quantitative In Situ Analysis, Applied and Environmental Microbiology 65,
3710-3713 (1999). Third, as a m community matures, it creates an oxygen gradient
such that an -rich environment exists on the outer edges of a biofilm, whereas an
oxygen-deprived, or anaerobic, area exists in the deepest ns of a biofilm. Walters et al.,
Contributions ofAntibiotic Penetration, Oxygen Limitation, and Low Metabolic Activity to
Tolerance ofPseua’omonas aeruginosa biofilms t0 Ci'profloxacin ana1 Tobramycin,
Antimicrobial Agents and Chemotherapy 47, 317-323 (2003); Borriello et al., Oxygen
Limitation Contributes to Antibiotic nce ofPseudomonas aeruginosa in Biofilms,
Antimicrobial Agents and Chemotherapy 48, 2659-2664 (2004). This may result in reduced
lic activity in those cells that dwell in the interior of the biofilm. Importantly,
traditional antibiotics are typically ive against bacterial cells that are rapidly dividing,
i.e., in a logarithmic phase of growth. Mandell, Interaction ofIntraleukocytic Bacteria and
Antibiotics, The Journal of Clinical Investigation 52, 1673—1673 (1973); Gilbert et al.,
Influence ofGrowth Rate on Susceptibility to Antimicrobial Agents: Biofilms, Cell Cycle,
Dormancy, ana1 Stringent Response, crobial Agents and Chemotherapy 34, 1865-1868
(1990). Fourth, in a mature m, water channels form throughout the community.
Stoodley et al., Liquidflow in biofilm systems, App Env Microbiol 60, 2711-2716 (1994).
These water channels have the ability to dlffilSC, remove or t toxic byproducts as well
as antibiotics from interacting with cells in the biofilm. For novel antimicrobial agents to be
effective over the long term, addressing each of these four characteristics may increase the
potential for success in a variety of applications including healthcare, industrial,
environmental, agricultural and sanitation industries. rmore, biofilms tend to secrete
proteoglycan materials that create an extracellular matrix, which has the y to potentially
bind and hinder the activity of antibiotics.
ative approaches to killing ia include the use of antimicrobial agents
that have fast-acting and nonspecific mode of activity against the cell membrane of bacteria.
These alternate compounds include detergents, squalamine, quaternary ammonium
compounds, and lly occurring antimicrobial peptides, among others. By attacking and
depolarizing the cell membrane in a nonspecific fashion at a faster rate, agents that attack the
cell membrane globally can kill bacteria before they have time to upregulate their defense
mechanisms. In addition, modes of action of these alternate crobials are not limited to
a specific protein or enzyme within a metabolic pathway.
r, as important as it is to kill bacteria and prevent their ability to cause
infections in humans or animals, or inate ed processes in industrial,
agricultural or environmental applications, when bacteria are attached to a surface, it
sometimes may be more beneficial to not only kill bacteria, but also to cause them to “fall
off’ of a surface as well, 6. g. disperse or ge bacteria in a biofilm community. In certain
aspects, the present invention provides compounds, compositions, and methods that have
shown the ability to disperse or dislodge bacterial cells in a biofilm, such that the cells are no
longer able to reattach and form new biofilm communities, and, notably, the same
compounds, compositions, and methods kill substantially all ia cells in a biofilm.
By dispersing a biofilm and killing the cells within it, at least two benefits are
provided. This may be particularly important when considering the fact that although
bacteria in a biofilm, which may be attached to a surface, can be killed by an antimicrobial
agent, the dead cells and extracellular matrix residues may provide an attachment point for
viable bacteria to re-adhere and form a biofilm once again with greater y. If biofilms
are dispersed and killed, viable bacteria that are introduced to a surface will have reduced
ability to preferentially adhere to that area. This can be particularly important in industrial
applications wherein the formation of biofilms on a surface can be problematic, as well as
medical applications wherein bacteria may adhere to the surface of a medical device. It has
been surprisingly discovered that compositions of the t invention have cant
potential to eradicate bacteria within a biofilm as well as cause the biofilm to se or
dislodge, resulting in a y of potential applications across multiple settings.
Thus, there is a need for novel compounds, compositions, and methods that have
potent antimicrobial and anti-biofilm activity against a variety of bacterial strains, especially
at high bacterial concentrations and against antibiotic-resistant ia.
BRIEF SUMMARY OF THE INVENTION
It is an object of the present ion to provide novel compounds, compositions,
and methods having antimicrobial ty and dispersing activity t a wide y of
bacterial strains capable of forming biofilms. In some preferred aspects, the invention
provides compounds, compositions, and methods that are effective against antibiotic—resistant
ial biofilms.
It has been discovered that nds, compositions, and s of the present
invention rapidly disperse biofilms and kill microorganisms such as bacteria, so that the
microorganisms do not have an opportunity to upregulate their defense mechanisms. Thus,
there may be a reduced risk of bacteria developing resistance to the compounds,
compositions, and s of the present invention. Furthermore, such compounds,
compositions, and methods may not be limited to eradicating bacteria that are in log-phase
growth. The ability of compounds, compositions, and methods of the t invention to
disperse biofilms while demonstrating antimicrobial activity may address many of the
characteristics that make biofilm communities difficult to treat using traditional antibiotics.
More specifically, by dispersing and killing bacteria in a biofilm, water channels and the
bacterial community as a whole may be broken apart, allowing for broader distribution of
antimicrobial agent(s) to a greater number, or even substantially all, of the cells within a
biofilm.
Aspects of this disclosure feature methods of g, dispersing, dislodging,
treating, and reducing biofilms as well as preventing or inhibiting biofilm formation. In some
ments, the method comprises exposing a biofilm to an effective amount of a
composition of the present invention to thereby kill, disperse, dislodge, treat, , prevent,
or inhibit ial biofilms.

DEFINITIONS
Unless otherwise defined, all technical and scientific terms used herein have the
same g as ly understood by one of ordinary skill in the art to which this
invention belongs. Although methods and materials r or equivalent to those described
herein can be used in the practice or testing of the present invention, suitable methods and
materials are described below. In addition, the materials, methods, and examples are
illustrative only and not intended to be limiting. All publications, patent applications,
patents, and other references mentioned herein are incorporated by reference in their entirety,
including U.S. Appl. Nos. 61/482,522; 61/482523; 61/591,601; 61/616,944; 61/826,453;
61/826,761; 61/836,555; 61/834,l49; 13/379,191; 14/076,143; and 14/076,149 as well as Int’l
Pat. Publ. Nos. , 2012/151555, and 2013/148230. In case of conflict, the
present specification, including these definitions, will control.
The terms “a,” “an,” and “the” as used herein not only includes aspects with one
member, but also es aspects with more than one member. For example, an
ment including “a polyamine compound and an excipient” should be understood to
present certain aspects with at least a second polyamine compound, at least a second
excipient, or both.
The term “about” as used herein to modify a numerical value indicates a defined
range around that value. If “X” were the value, “about X” would generally te a value
from 0.95X to 1.05X. Any nce to “about X” specifically indicates at least the values X,
0.95X, 0.96X, 0.97X, 0.98X, 0.99X, 1.01X, 1.02X, 1.03X, 1.04X, and 1.05X. Thus, “about
X” is intended to teach and provide written description support for a claim limitation of, e.g.,
“0.98X.” When the quantity “X” only includes whole—integer values (e.g., “X carbons”),
“about X” indicates from (X-l) to (X+l). In this case, “about X” as used herein specifically
indicates at least the values X, X-1, and X+1.
When “about” is applied to the beginning of a numerical range, it applies to both
ends of the range. Thus, “from about 5 to 20%” is equivalent to “from about 5% to about
%.” When “about” is applied to the first value of a set of values, it applies to all values in
that set. Thus, “about 7, 9, or 11%” is equivalent to “about 7%, about 9%, or about 11%.”
[0064] The term “acyl” as used herein includes an alkanoyl, aroyl, heterocycloyl, or
heteroaroyl group as defined . Examples of acyl groups include, but are not limited to,
acetyl, benzoyl, and nicotinoyl.
The term “alkanoyl” as used herein es an alkyl-C(O)- group wherein the alkyl
group is as defined herein. Examples of alkanoyl groups include, but are not limited to,
acetyl and propanoyl.
The term “agent” as used herein includes a compound or mixture of compounds
that, when added to a composition, tend to e a particular effect on the composition’s
properties. For example, a composition sing a thickening agent is likely to be more
s than an otherwise identical comparative composition that lacks the ning agent.
[0067] The term “alkenyl” as used herein includes a straight or branched chain
hydrocarbon ning at least one carbon-carbon double bond. The chain may contain an
indicated number of carbon atoms. For example, “Cl-Cu alkenyl” indicates that the group
may have from 1 to 12 (inclusive) carbon atoms and at least one carbon-carbon double bond.
When the indicated number of carbon atoms is 1, then the Ci alkenyl is double bonded to a
carbon (i.e., a carbon lent to an oxo group). In certain aspects, the chain includes 1 to
12, about 2 to 15, about 2 to 12, about 2 to 8, or about 2 to 6 carbon atoms. Examples of an
alkenyl group may include, but are not limited to, ethenyl (z'.e., vinyl), allyl, propenyl,
butenyl, crotyl, pentenyl, hexenyl, heptenyl, octenyl, nonenyl, decenyl, dodecenyl,
cyclopentenyl, cyclohexenyl, 2-isopentenyl, l, butadienyl, pentadienyl, 3-(l,4-
pentadienyl), and hexadienyl.

of a disorder or a symptom thereof. Such improvements can include, but are not d to,
alleviation or amelioration of one or more ms or conditions, diminishment of the
extent of a disease, stabilizing (i.e., not worsening) the state of disease, prevention of a
disease’s transmission or spread, delaying or slowing of disease progression, amelioration or
palliation of the disease state, diminishment of the reoccurrence of disease, and remission,
whether partial or total and whether detectable or undetectable.
This can be evidenced by, e.g., an improvement in a ter associated with a
m or with a m-related disorder or an indication or symptom thereof, a biofilm-
related industrial, agricultural, environmental, etc. condition, e.g., to a tically significant
degree or to a degree detectable to one d in the art. An effective amount, manner, or
mode can vary depending on the surface, application, or subject and may be ed to the
e, application, or subject. By eradicating a biofilm or preventing or slowing
progression of a biofilm or of a biofilm-related disorder or an indication or symptom thereof,
or a biofilm-related industrial, agricultural, environmental, etc. condition, a treatment can
prevent or slow deterioration or corrosion resulting from a biofilm or from a biofilm-related
disorder or an indication or symptom thereof on an affected surface or in an affected or
sed subject.
ing” and “treatment” as used herein also include prophylactic treatment. In
certain embodiments, treatment methods comprise administering to a subject a
therapeutically effective amount of a ition of the invention. The administering step
may consist of a single administration or may comprise a series of administrations. The
length of the treatment period depends on a variety of factors, such as the severity of the
condition, the age of the patient, the concentration of active agent in the composition, the
ty of the compositions used in the treatment, or a combination thereof. It will also be
appreciated that the effective dosage of an agent used for the ent or laxis may
increase or decrease over the course of a particular treatment or prophylaxis . Changes
in dosage may result and become apparent by standard diagnostic assays known in the art. In
some aspects, chronic administration may be required. For example, the compositions are
administered to the subject in an amount, and for a duration, sufficient to treat the patient.

POLYAMINE COMPOUNDS
Aliphatic polyamines, for example, spermine, spermidine, norspermine,
norspermidine, hexamethylenediamine, 1,12-diaminododecane, 1,3-diaminopropane, etc.,
have been shown to have some activity against a y of bacterial strains when used alone.
In particular, it has been shown that norspermine and norspermidine may be effective in
dispersing various biofilm strains. However, it does not appear that these polyamines have
sufficient bactericidal activity.
It has been surprisingly discovered that by attaching one or more polyamine chains
to a lipophilic or hydrophobic moiety, examples of which may include cyclic or aromatic
IO backbone molecules, results in novel compounds that are capable of dispersing biofilms and
that also have substantial antimicrobial activity against a variety of s of bacteria (e. g.,
by killing the bacteria).
Referring now to there is shown a simplified schematic of an exemplary
polyamine compound of the t ion, generally indicated at 10. The polyamine
compound 10 may be generally characterized as including a lipophilic or hydrophobic moiety
, and one or more ic residues 30. In some embodiments, the polyamine compound
may e one or more cationic residues 30 comprising primary amines 40 and one or
more secondary amines 50. In some embodiments, the polyamine compound 10 may include
one or more cationic residues 30 having a tertiary or quaternary amine (not shown).
[0108] As depicted in exemplary polyamine nds 10 of the present invention
may be amphipathic, e.g. the cationic residues 30 may be generally disposed along one face
ofthe molecule, while the lipophilic or hydrophobic moiety 20 is generally ed along
the opposite face of the molecule.
In n embodiments, the present invention provides polyamine compounds and
compositions and methods comprising such compounds. In certain embodiments, the
polyamine compounds comprise one or more polyamine side chains (e.g., l, 2, 3, 4, 5, 6, 7, 8,
... n polyamine moieties/side chains) that may be the same or different. In n
embodiments, the amino groups of the one or more polyamine side chains may be ionizable.
In n ments, the amino groups may be positively d. In some embodiments,
the ine side chains are branched. In some embodiments, the polyamine chains are
linear.
FIGs. 2A-2H show ary backbone les, which may be used to prepare
certain novel polyamine compounds. It will be appreciated by those skilled in the art that
alternative backbone molecules may be used to produce ine compounds according to
certain aspects of the present invention. Without being bound by , it is believed that
the lipophilicity or hydrophobicity of a ne molecule of novel polyamine compounds
may contribute to the antimicrobial activity or biofilm dispersing activity of these novel
compounds.
shows exemplary polyamine chains, which may be used to prepare certain
novel ine compounds according to certain s of the present invention. It will be
appreciated by those skilled in the art that polyamine chains are intended to only be
representative. Without being bound by theory, it is believed that increasing the number of
primary or secondary amines of polyamine compounds of the present invention may increase
the antimicrobial activity or biofilm dispersing activity of these novel compounds.

(3 -aminopropylamino)propyl]propane-l,3—diamine), or a combination thereof.
[0115] Exemplary compositions of the present invention may include a compound
comprising a single polyamine chain or multiple polyamine chains attached to a base
backbone compound to improve their antimicrobial activities or improve certain other
features or aspects not present when polyamines are used alone such that the itions
may be ed for use in a specific application. Furthermore, it has been surprisingly
discovered that by increasing the number ofprimary and ary amines within a single
molecule an increase in the antimicrobial activity of a compound may result. rmore,
exemplary novel polyamines may be used in combination (6.g. formulated as a composition)
with already approved, commercial antimicrobial products (6.g. chlorhexidine gluconate) to
improve the dispersing or killing ability of such compositions.

In some apects, the ine compound is a compound of Formula I-P, Formula

from 1 to 6. The polyamine compound comprises a hydrophobic phenyl group and at least

[0201] In certain aspects, the compounds of the t invention are antimicrobial and
provide triple action against bacteria and biofilms. ageously, the antimicrobial
compounds of the t invention have specific activity against biofilms.
Organisms residing in biofilms present a complex extracellular matrix of
polysaccharides (exopolysaccharides) and proteins. As a result of this complex matrix,
nutrient-limiting conditions exist that alter the normal or planktonic metabolic state. These
conditions reduce the efficacy of ional antibiotic agents, rendering them up to l,000x
less active against biofilms. A hallmark of these exopolysaccharides is the presentation of
acidic es from repeated glucoronic acid motifs and pyruvate derived acetals. A recent
study by Losick and kers demonstrated that the simple polyamines spermine and
norspermidine (A) were naturally occurring inhibitors of biofilm formation,
endogenously produced at high concentrations (5 0-80 uM) in response to nutrient limiting
conditions and waste accumulation in mature pellicles (Kolodkin-Gal, I. et al., A self-
produced trigger for biofilm disassemby that targets exopolysaccharide. Cell 149 (2012)). In
this study, they were able to demonstrate that norspermidine could t biofilm formation
at 25 uM and showed that, at similar concentrations, it could disperse the exopolysaccharide
component of the matrix but not the protein ent. Interestingly, dine was only
active at much higher concentrations (~l mM) leading them to propose a ale for this
activity in the ability of the polyamines to engage the acidic es in the matrix at regular
intervals (B).
In certain aspects, compounds of the present invention having increased numbers of
chains, produce a more effective compound against A. baumanniz’. For example, compounds
with four polyamine chains can be generated with Pd(II) mediated dimerization of 5-
bromoisopthalaldehyde followed by reductive amination ().
[0204] In certain s, the compounds of present invention combine a hobic
backbone with a cationic tail that have the functionality to inhibit biofilm formation, disrupt
established biofilms, and kill the emerging planktonic bacteria. Certain of the compounds of
the ion are set forth in FIGS. 27 and 28.
In a particular embodiment, the polyamine compound may comprise a hydrophobic
I5 moiety head and at least one hydrophilic moiety tail comprising a polyamine group. When
the polyamine compound comprises more than one hydrophilic moiety tails, the hydrophilic
moiety tails may be the same, or alternatively, the hydrophilic moiety tails may be different.
As discussed above, the exemplary polyamine nds shown herein are not
ed to be ng.
SYNTHESIS
The synthesis of diaminopropane substituted backbones is straightforward and
results in CZ-4, 12, 32 () from the known mono-Boc protected diaminopropane and
commercially available aldehydes (benzaldehyde, isopthalaldehyde or 1,3,5—
benzenetricarboxaldehyde). This three-step synthetic procedure ds Via ive
amination (Baxter, E. W. & Reitz, A. B. Reductive Aminations of Carbonyl nds with
Borohydride and Borane Reducing Agents. Org Reac l, 59 (2004)) and acidic removal of the
Boc group. The norspermidine series (e.g., CZ-7, CZ-25, and CZ-52) can be prepared in a
similar manner from the mono-Boc protected norspermidine (). No purification is
required until a final recrystallization of the HCl salt, which has allowed easy preparation of
these compounds on larger scale.
In some embodiments, the polyamine compound may be produced by the reductive
amination method of General tic Scheme 1.

butyldicarbonate nd [(Boc)20] to protect at least one terminal amine group of the
polyamine [1], while leaving at least one terminal amine group of the polyamine [1]
unprotected. The resulting polyamine of formula [2] having at least one Boc-protected

protected with a Boc-protecting group, in a presence of base such as triethylamine (NEt3) to

The polyamine compounds exhibit unexpectedly superior ability in treating
biofilms, compared to most known antimicrobial compounds. The microorganisms in the
biofilm community may be eradicated ively and rapidly such that they have minimum,
if any, opportunity to upregulate their defense ism and develop resistance against the
polyamine compound. Without being bound by any theory, it is believed that the
unexpectedly superior biofilms treatment is due to the beneficial synergistic of
hobicity and hydrophilicity of the polyamine compound. It is believed that the
hobic moiety of the ine compound facilitates the dispersion of the
microorganisms in biofilms, while the hydrophilic polyamine moiety provides an
antimicrobial effect on the dispersed microorganisms.
The polyamine compounds may eradicate the biofilms, reduce the formation of
biofilms, or inhibit the formation of ms. The hydrophobicity and hydrophilicity of the
polyamine compounds may be designed by tailoring the hydrophobic moieties and
hydrophilic es of the polyamine compounds such that the desired level of antimicrobial
effect on the biofilms may be achieved. One d in the arts recognizes the ters
controlling the hydrophobicity/hydrophilicity effect, and, therefore, may readily modify the
teachings of t disclosure to produce various polyamine compounds without departing
from the scope of present sure. As non-limiting examples, the hydrophilicity effect of
the polyamine compound may be modified by varying numbers of the hydrophilic ine
chains in the polyamine compound, numbers of amine groups in the hilic polyamine
chains, numbers of s between amine groups in the hydrophilic polyamine chains, etc.
As non-limiting examples, the hydrophobicity effect of the polyamine compound may be
modified by g positions of the hydrophilic polyamine chains on the hydrophobic
groups, altering chemical structures of the hydrophobic groups to other known non-polar
functional group, etc.
The polyamine compounds may exhibit enhanced antimicrobial effect on ms
comprised of Gram-negative or Gram-positive bacteria. The polyamine compounds may
exhibit enhanced antimicrobial effect on biofilms consisting of mycobacteria.
In one embodiment, the antimicrobial composition may comprise a polyamine
compound and at least one additive. Various additives may be used for the antimicrobial
composition. By way of non-limiting examples, the additives may further enhance the
dispersion of microorganisms in biofilms, impart the antimicrobial effect against the
dispersed microorganisms, facilitate the application/administration of the antimicrobial
composition to the biofilms, improve the stability of the antimicrobial composition, control
the release/application rate of the antimicrobial composition to the biofilms, etc. Non-
ng examples of additives for further enhancing the antimicrobial effect may be e
and other bactericide. By way of non-limiting examples, the additives for facilitating the
administration of the antimicrobial composition may e a pharmaceutically acceptable
carrier typically used for medical or pharmaceutical ations, an emulsifier or dispersant
typically used for industrial applications.
The antimicrobial composition may be formulated to provide the desired level of
crobial effect on the biofilms by selecting a polyamine compound and other ves
as well as by adjusting the amount of each component in the antimicrobial composition. In
some ments, the antimicrobial composition may be formulated to inhibit the formation
of biofilms. In some embodiment, the antimicrobial composition may be formulated to
disrupt the biofilms. In still other embodiments, the antimicrobial composition may be
formulated to ate substantially all microorganisms in the biofilms.
Any suitable amount amine can be used in the compositions and methods of
the invention. In general, the polyamines are used in concentrations ranging from about 1
ppm to about 100,000 ppm, or higher. The concentration of a polyamine used in a
composition or method of the invention can be, for example, from about 1 to about 100,000
ppm, or from about 10 to about 10,000 ppm, or from about 100 to about 1,000 ppm, or from
about 1 to about 100 ppm, or from about 1,000 to about 10,000 ppm, or from about 10,000 to
about 100,000 ppm. The concentration of a polyamine can be about 1; 2; 3; 4; 5; 6; 7; 8; 9;
; 15; 20; 25; 30; 35; 40; 45; 50; 55; 60; 65; 70; 75; 80; 85; 90; 95; 100; 125; 150; 175; 200;

92,500; 95,000; 97,500; or about 100,000 ppm. Other concentrations ofpolyamines can be
usefial in the compositions and methods of the ion, depending in part on factors
including the specific polyamine used, the presence of potentiating agents if any, or the
species ofmicroorganisms that are targeted.
In certain aspects, increasing number of polyamine chains on the hydrophobic
backbone systematically increase the antimicrobial activity. For example, it is demonstrated
herein that with a single chain of diaminopropane added to a benzyl backbone (CZ-4, ), the MIC (as defined by the Clinical and Laboratory Standards Institute (CLSI)) against
MRSA is greater than 1,200 ug/mL, whereas two chains decrease the MIC to 300 ug/mL
) and three chains reduce it r to 45 ug/mL (CZ-32). Similarly, with a single
chain ofnorspermidine attached to a benzyl backbone (CZ-7, ), the MIC against
MRSA is greater than 1,200 ug/mL. By adding a second chain of norspermidine (CZ-25),
the MIC is 45 ug/mL. With a third chain of norspermidine attached (CZ-52), the MIC
becomes 3 ug/mL ().
This trend of ing antimicrobial activity by sing the number of
polyamine chains attached to a backbone is effective for treating MRSA, but modulating this
trend with increased hydrophobicity enhances the activity of CZ compounds against A.
baumanm‘i. Interestingly, CZ-52, with three norspermidine chains, has greater activity
against MRSA s than against A. nii, whereas CZ-58 () has greater
activity (10-fold increase) against A. baumanm’z’ biofilms than MRSA biofilms (see Table 4
below).

In some embodiments, the composition is administered to a surface of the t
selected from the group of dermal and mucosal surfaces and combinations thereof. In other
embodiments, the surface is an oral surface, a skin surface, a urinary tract surface, a vaginal
tract surface, or a lung surface.
In some embodiments, the ition is administered to the subject via
subcutaneous, intra-muscular, intra-peritoneal, intravenous, oral, nasal, or topical
administration, and a combination thereof.
In some aspects, a subject is treated. A subject can be a mammal including, but not
limited to, a primate (e.g., a monkey, such as a cynomolgous monkey, a chimpanzee, and a
human). A t can be a non-human animal such as a bird (e.g., a quail, chicken, or
), a farm animal (e.g., a cow, goat, horse, pig, or sheep), a pet (e.g., a cat, dog, or
guinea pig, rat, or mouse), or laboratory animal (e.g., an animal model for a disorder). Non—
limiting entative subjects can be a human infant, a pre-adolescent child, an adolescent,
an adult, or a senior/elderly adult.
In some embodiments, the subject is a human.
In some instances, a subject in need of treatment can be one afflicted with one or
more of the infections or disorders described herein. In some aspects, the subject is at risk of
developing a biofilm on or in a biologically relevant surface, or already has developed such a
biofilm. Such a subject at risk can be a candidate for ent with a polyamine compound,
or ation of a polyamine compound with another compound, in order to inhibit the
development or onset of a biofilm—production—related er/condition or prevent the
3O recurrence, onset, or development of one or more symptoms of a biofilm-related disorder or
ion. Such a subject can be harboring an immature biofilm that is ally evident or
detectable to the skilled n, but that has not yet fully formed. A subject at risk of
developing a biofilm can also be one in which implantation of an indwelling device, such as a
medical device, is scheduled. The risk of developing a biofilm can also be due to a
propensity of ping a biofilm—related disease (such as the presence of a channel
transporter mutation associated with cystic fibrosis). In such subjects, a biofilm-related
disorder can be at an early stage, e.g. no bacterial infection or biofilm formation is yet
detected.
In certain embodiments a biofilm—related disorder is selected from pneumonia,
cystic fibrosis, otitis media, chronic obstructive pulmonary disease, and a urinary tract
infection and combinations thereof. In other ments, the -related disorder is a
medical device-related infection. In r embodiments, the biofilm-related disorder is a
periodontal disease, such as gingivitis, periodontitis or breath malodor. In still further
embodiments, the biofilm—related disorder is caused by bacteria. In some embodiments, the
bacteria are Gram-negative or Gram-positive bacteria. In still other embodiments, the bacteria
are of the genus Actinobacillus, Acinetobacter, Aeromonas, Bordetella, Brevibacillus,
Brucella, Bacteroia'es, Burkhola'eria, Borelia, us, obacter, Capnocytophaga,
Cardiobacterium, Citrobacter, Clostridium, dia, Eikenella, Enterobacter,

Yersinia, or Xanthomonas.
[0307] miting examples of -related disorders include otitis media, prostatitis,
cystitis, bronchiectasis, bacterial endocarditis, osteomyelitis, dental caries, periodontal
disease, infectious kidney stones, acne, Legionnaire's disease, chronic obstructive pulmonary
disease (COPD), and cystic fibrosis. In one specific example, subjects with cystic fibrosis
display an accumulation of biofilm in the lungs and digestive tract. ts afflicted with
COPD, such as emphysema and chronic bronchitis, display a characteristic ation of
the airways wherein airflow through such airways, and subsequently out of the lungs, is
chronically obstructed.
Biofllm-related disorders can also encompass infections derived from
implanted/inserted devices, medical device-related infections, such as ions from biliary
stents, orthopedic t infections, and er-related infections (kidney, vascular,
peritoneal). An infection can also originate from sites where the integrity of the skin or soft
tissue has been compromised. miting examples include dermatitis, ulcers from
peripheral vascular disease, a burn , and trauma. For example, a ositive
bacterium, such as S. pneumoniae, can cause opportunistic ions in such tissues. The
ability of S. pneumoniae to infect burn wound sites, e. g., is enhanced due to the breakdown of
the skin, burn-related immune defects, and antibiotic selection.
[0309] In yet other embodiments, a biofilm-related disorder is pneumonia, cystic fibrosis,
otitis media, chronic ctive pulmonary disease, or a urinary tract infection. In some
embodiments, the biofllm-related disorder is a medical device-related infection.
In other aspects, this sure features compounds, compositions, or methods,
such as industrial, therapeutic or pharmaceutical compositions, comprising polyamine
compounds in combination with one or more additional active itions.
In some instances a polyamine nd can be administered alone or in
combination with a second agent, 6.g. a biocide, an antibiotic, or an antimicrobial agent, to
thereby kill, disperse, treat, reduce prevent, or inhibit bacterial biofilms. An antibiotic can be
co-administered with the polyamine compound either sequentially or simultaneously.
[0312] The antibiotic can be any compound known to one of ordinary skill in the art that
can inhibit the growth of, or kill, bacteria. UsefiJl, miting examples of antibiotics
include lincosamides (clindomycin); chloramphenicols; tetracyclines (such as tetracycline,
chlortetracycline, demeclocycline, methacycline, doxycycline, minocycline);

A pharmaceutical composition containing a ine compound, or combination
of a polyamine compound with another compound, can be ated to be compatible with
its intended route of administration as known by those of ordinary skill in the art. Nonlimiting
es of routes of administration include parenteral, e. g., intravenous, intradermal,
subcutaneous, oral {e.g., inhalation), transdermal (topical), transmucosal, vaginal and rectal
administration. Solutions or suspensions used for parenteral, intradermal, or subcutaneous
application can include the following components: a sterile diluent such as water for
injection, saline solution, fixed oils, polyethylene glycols, glycerine, propylene glycol or
other synthetic solvents; antibacterial agents such as benzyl alcohol or methyl ns;
antioxidants such as ascorbic acid or sodium bisulfite; chelating agents such as
nediaminetetraacetic acid; buffers such as acetates, citrates or phosphates and agents
for the adjustment of tonicity such as sodium chloride or dextrose. The pH can be adjusted
with acids or bases, such as hydrochloric acid or sodium hydroxide. The parenteral
preparation can be enclosed in ampoules, disposable syringes or multiple dose Vials made of
glass or plastic.
Pharmaceutical itions suitable for injectable use include sterile aqueous
solutions (where water —soluble) or dispersions and sterile s for the extemporaneous
preparation of sterile inj ectable solutions or dispersion. For intravenous administration,
suitable carriers e physiological saline, bacteriostatic water, Cremophor ELTM (BASF,
Parsippany, N.J.) or ate buffered saline (PBS). In all cases, the composition can be
sterile and can be fluid to the extent that easy syringability exists. It should be stable under
the conditions of manufacture and storage and must be preserved against the contaminating
action of microorganisms such as ia and fungi. The carrier can be a solvent or
dispersion medium containing, for example, water, ethanol, polyol (for example, glycerol,
propylene glycol, and liquid polyethylene glycol, and the like), and suitable mixtures thereof.
The proper fluidity can be maintained, for example, by the use of a g such as lecithin,
by the maintenance of the required particle size in the case of dispersion and by the use of
surfactants. Prevention of the action of microorganisms can be achieved by various
antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, ascorbic
acid, thimerosal, and the like. It may be desirable to include isotonic agents, for example,
sugars, polyalcohols such as mannitol, sorbitol, or sodium chloride in the composition.
Prolonged absorption of the injectable itions can be accomplished by including in the
composition an agent that delays absorption, for e, aluminum monostearate and
n (see, e. g., Remington: The Science and ce of cy, 21st edition, Lippincott
Williams & Wilkins, Gennaro, ed. (2006)).
Sterile inj ectable solutions can be prepared by orating a polyamine
compound, or combination of a polyamine compound with another compound, in the ed
amount in an riate solvent with one or a combination of ingredients enumerated above,
as required, followed by filtered sterilization. Generally, dispersions are ed by
incorporating an active compound into a sterile vehicle that contains a basic dispersion
medium and the required other ingredients from those enumerated above. In the case of
sterile powders for the preparation of sterile inj e solutions, the methods of preparation
include, without limitation, vacuum drying and freeze-drying which yields a powder of the
active ingredient plus any additional desired ingredient from a usly sterile-filtered
solution thereof.
Oral compositions may include an inert diluent or an edible carrier or binders. For
the purpose of oral eutic stration, a polyamine, or a combination of a polyamine
compound, or combination of a polyamine compound with another compound, can be
incorporated with excipients and used in the form of tablets, pills, troches, or capsules, e.g.,
gelatin capsules. Oral compositions can also be prepared using a fluid carrier for use as a
mouthwash. Pharmaceutically compatible binding agents, or adjuvant als can be
included as part of the composition. The tablets, pills, capsules, troches and the like can
contain any of the ing ingredients, or compounds of a similar nature: a binder such as
microcrystalline cellulose, gum tragacanth or gelatin; an excipient such as starch or lactose, a
disintegrating agent such as alginic acid, Primogel, or corn starch; a lubricant such as
magnesium stearate or Sterotes; a glidant such as colloidal silicon e; a sweetening
agent such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate,
or orange flavoring.
For administration by inhalation, polyamine compound, or combination of a
polyamine compound with another compound, can be delivered in the form of an aerosol
spray from pressured ner or dispenser that contains a suitable propellant, e.g. a gas
such as carbon dioxide, or a zer.
Systemic administration can also be by transmucosal or transdermal means. For
transmucosal or transdermal administration, penetrants appropriate to the barrier to be
ted are used in the formulation. Such penetrants are generally known in the art, and
include, but are not limited to, for example, for transmucosal administration, detergents, bile
salts, and c acid derivatives. Transmucosal administration can be accomplished through
the use of nasal sprays or suppositories. For transdermal administration, the active
compounds and itions are formulated into pharmaceutically able formulation
embodiments, such as nts, salves, gels, or creams as generally known in the art.
For treatment of acute or chronic wounds, polyamine compound, or combination of
a polyamine compound with another compound, can be formulated as a ng, a wash
solution, gel, or a synthetic tissue, etc.
The pharmaceutical compositions containing a polyamine compound, or
combination of a polyamine compound with another compound, can also be prepared in the
form of suppositories (e.g., with conventional itory bases such as cocoa butter and
other glycerides) or retention enemas for rectal delivery.
Some pharmaceutical compositions containing a polyamine compound, or
combination of a polyamine compound with r compound, can be prepared with a
carrier that protects the polyamine compound, or combination of a polyamine compound with
another nd, against rapid elimination from the body, such as a controlled release
formulation, including implants and microencapsulated delivery systems as described, e.g., in
Tan et al., Pharm. Res. 7-2308 (2007).
Additionally, biodegradable, biocompatible polymers can be used, such as ethylene
vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic
acid. Methods for preparation of such formulations are apparent to those skilled in the art.
The materials can also be obtained commercially (e.g., from Alza Corp, Mountain View,
Calif). Liposomal suspensions (including mes targeted to particular cells with
onal antibodies to cell surface antigens) can also be used as pharmaceutically
acceptable carriers. These can be prepared according to methods known to those skilled in the
art, e.g., as described in US. Pat. No. 4,522,811.
ty and therapeutic efficacy of such compounds and compositions can be
determined by standard pharmaceutical procedures in cell cultures or experimental animals,
e.g., for determining the LD50 (the dose lethal to 50%> of the population) and the ED 50 (the
dose therapeutically effective in 50% of the population). The dose ratio between toxic and
therapeutic effects is the therapeutic index and it can be expressed as the ratio LDSQ/EDso.
While nds and compositions that t toxic side effects can be used, care should be
taken to design a delivery system that targets active components to the site of affected tissue
in order to minimize potential damage to normal cells and, thereby, reduce side effects.
The data obtained from the cell culture assays and animal studies can be used in
formulating a range of dosage for use in humans. The dosage of such compounds and
compositions lies generally within a range of circulating concentrations that include the ED50
with little or no toxicity. The dosage can vary within this range depending upon the dosage
form employed and the route of administration utilized. For any nds or compositions
used in the methods described herein, the therapeutically effective dose can be estimated
lly from cell culture assays. A dose can be ated in animal models to achieve a
circulating plasma concentration range that includes the ICso (i.e., the concentration of the
test compound or composition that achieves a half-maximal inhibition of symptoms) as
determined in cell culture. Such information can be used to more tely determine useful
doses in humans. Levels in plasma can be measured, for example, by high performance liquid
chromatography. Information for preparing and testing such compositions are known in the
art. See, e.g., Remington: The Science and Practice of Pharmacy, 21st ed., Lippincott
Williams & Wilkins, Gennaro, ed. (2006).
A physician will appreciate that certain factors may influence the dosage required to
ively treat a subject, including but not limited to the severity of the e or disorder,
previous treatments, the general health or age of the subject, and other diseases present.
Moreover, treatment of a subject with a therapeutically effective amount of a polyamine
compound, or combination of a polyamine nd with another compound, can include a
single treatment or a series of treatments.
The compounds or pharmaceutical compositions can be included in a container,
pack, or ser together with instructions for stration. A person of ry skill in
the art will appreciate that the compounds or ceutical compositions described herein
can be formulated as single—dose vials.
ine compounds, or combination of a polyamine compound with another
compound, may be suitable as antibiofilm active substances in personal care ations, for
example shampoos, bath additives, hair care preparations, liquid and solid soaps (based on
synthetic surfactants and salts of saturated or unsaturated fatty acids), lotions and creams,
deodorants, other aqueous or alcoholic solutions, e. g. cleansing solutions for the skin, moist
cleaning cloths, oils or powders.
Any suitable amount ofpolyamine can be used in the compositions and methods of
the invention. In general, the polyamines are used in concentrations ranging from about 1
ppm to about 0 ppm, or higher. The concentration of a polyamine used in a
composition or method of the invention can be, for example, from about 1 to about 100,000

[0341] There is thus disclosed compounds, compositions, or methods comprising novel
polyamine compounds, or combinations of polyamine compounds with other compounds,
that have antimicrobial activity and dispersing activity against a y of ial strains
capable of forming biofilms, and methods of using the same.
EXAMPLES
[0342] The following examples serve to n ments of the present disclosure in
more detail. These examples should not be construed as being exhaustive or exclusive as to
the scope of this disclosure.
The ing material and methods were used.
Bacterial strains. A al strain of MRSA, isolated from a patient who underwent
arthroscopic knee surgery and characterized by ARUP tories, Salt Lake City, UT, was
used for this study in addition to monas aeruginosa ATCC 27853 and Alcanivorax
ensz's ATCC 700651. Both ATCC strains were purchased as freeze-dried pellets from
ATCC. P. aeruginosa was resuspended in BHI broth, grown overnight at 37° C and
transferred to fresh BHI with 30% glycerol for e at -80° C. The MRSA isolate was
likewise stored in BHI with 30% glycerol at -80° C. Notably, the clinical MRSA isolate was
not passaged more than three times prior to or during the study. Prior to performing MIC
analysis and biofilm experiments, the frozen stocks ofMRSA and P. aeruginosa were
streaked onto Columbia blood agar plates and grown overnight at 37° C. A. ensz's
ATCC 70065] was resuspended from a lyophilized pellet into marine broth, grown overnight
at 30° C and passaged on marine agar plates prior to experimentation.
Example 1
[0345] MIC Determination. To determine the MIC of the polyamine chains alone and the
synthesized compounds against MRSA and P. aeruginosa ATCC 27853, a modified protocol
from the al and Laboratory Standards Institute (CLSI) guideline M26-A was used.
Consistent with this guideline, the MIC was defined as the tration of antimicrobial that
was ed to reduce approximately 5 x 105 cells per mL to approximately 5 x 102 per mL
in a 24-hour period. Each MIC experiment was performed n=10 times for each antimicrobial.
All data was collected using cation adjusted MHB for standardization.
As mentioned, MRSA and P. aeruginosa ATCC 27853 were grown on Columbia
blood agar plates prior to experimentation. From the blood agar plates, a 0.5 McFarland
standard was made of each isolate. This equated to approximately 5 x 107 cells/mL for the
MRSA isolate and approximately 3 x 107 cells/mL for the P. aeruginosa ATCC 27853
isolate. Of the 0.5 and stock solution, 50 [LL were added to MHB. All of the
antimicrobials were kept in PBS stock solutions at 10 mg/mL and diluted in the MHB to
reach the desired concentration that would determine the MIC value. All tests were
performed such that a final volume of 5 mL ofMHB were obtained. This provided a final
bacterial concentration of approximately 5 x 105 cells/mL.
Each sample was incubated in glass test tubes at 37° C for 24 hours, then plated in
duplicate on tryptic soy agar (TSA) using a 10-fold dilution series. TSA plates were further
incubated 24 hours at 37° C. The number of colony forming units (CFU) that grew were
d in order to calculate the number of bacteria that were present per mL in the original
MHB solution. The concentration of compound that ed in a reduction of approximately
x 105 cells/mL to imately 5 x 102 cells/mL in a r period was defined as the
MIC.
For comparison to a current rd of care, the MICs of vancomycin against the
MRSA isolate and tobramycin against the P. aeruginosa ATCC 27853 isolate were also
determined. MIC results for various compounds are shown in
MRSA and P. aeruginosa Biofilm Eradication. s ofMRSA and P.
aeruginosa ATCC 27853 were grown on the surface of PEEK nes using a membrane
biofilm r. Data demonstrating the design and repeatability of this reactor have been

mature biofilms on the surface ofPEEK membranesfor an in vivo animal model application,
Curr Microbiol 62, 663 (2011). Prior to growing the biofilms, PEEK nes were
first sonicated for 10 min in medical grade detergent, rinsed with running reverse osmosis
water for 10 min, sonicated in reverse osmosis water for 10 min and rinsed once again using
70% ethanol.
Four guillotine—like holders were designed to hold eight PEEK nes (two per
holder). All components were washed, assembled and the reactor autoclaved prior to each
use. Following American Society for Testing and Materials (ASTM) standard E2562-07, the
modified reactor was run under the following conditions: approximately 5 x 107 ial
cells were inoculated into 500 mL of BHI in the biofilm reactor. A paddle in the base of the
reactor was stirred at 130 rpm. The unit was placed on a hot plate set at 33° C for 24 hrs. A
% BHI broth solution was then fiowed through the reactor at 6.94 mL/min for an additional
24 hrs.
Following the 48-hour growth period, six of the PEEK membranes were cally
removed and placed into 5 mL of MHB that contained varying concentrations of the
synthesized compounds. For ison, vancomycin was also tested against MRSA
biofilms and tobramycin was tested against P. aeruginosa ATCC 27853 biofilms. The
membranes and broth were incubated in glass test tubes at 370 C for 24 hours. The test tubes
containing membranes were vortexed for 1 minute, sonicated at 42 kHz for 10 minutes and
plated in duplicate on TSA using a 10-fold dilution series and incubated at 37° C for 24
hours. This process allowed for the ination ofwhat was defined as the effective
biofilm eradication concentration (EBEC) of the selected compounds. In this case, the EBEC
was defined as the concentration of compound required to reduce the number of cells in the
biofilms from approximately 109 cells/PEEK membrane to 105 cells/membrane. A level of
109 bacteria in the biofilms represented an amount of bacteria that may be present in one
gram of soil in a natural ecosystem. See e.g., Bakken, Separation and Purification of
Bacteriafrom Soil, Appl Environ Microbiol 49, 1482-1487 (1985); Torsvik et al., High
Diversity in DNA ofSoil Bacteria, Applied and Environmental Microbiology 56, 782-787
(1990).
[0352] Two membranes from each run of the reactor were aseptically removed and
quantified to serve as positive controls of biofilm . All of the biofilm eradication
studies were repeated n=5 times. EBEC s are summarized in FIGs. 12A and 12B.

Example 2
A compound was screened for its ability to create zones of inhibition on cation
adjusted Mueller Hinton agar. It is believed that the compound of Example 2 may be
represented by the structure disclosed in . To perform this test, lawns of methicillin—
resistant Staphylococcus aureus (MRSA) or Pseudomonas aerugz'nosa ATCC 27853 were
made on cation adjusted Mueller Hinton agar using standard microbiological ques.
Immediately after g bacteria on agar, a 50 [LL drop of the compound was placed onto
the agar surface. The compound was tested in duplicate at 100 ug/mL, 50 ug/mL, 25 ug/mL
and 10 ug/mL. All plates were incubated at 370 C for 24 hours. Results indicated that total
clearing was seen against MRSA at 10 ug/mL. Partial ng was seen against P.
aerugz'nosa at 25 ug/mL and total clearing at 50 ug/mL.
The second test determined the minimum inhibitory concentration (MIC) of the
compound t MRSA and P. aerugz'nosa ATCC 27853. In this instance, the MIC was
defined as the amount of antimicrobial required to reduce 105 cells/mL to 102 cells/mL in a
24-hour period. This definition was tent with the al and Laboratory Standards
Institute (CLSI). More specifically, the microdilution method as outlined in the M26-A CLSI
guideline was used. All tests were med with cation adjusted Mueller Hinton broth.
MIC data are presented in Table l.
[0359] In addition to determining the MIC, the minimum biofilm ation concentration
(MBEC) of PBC-51 was also ined. The MBEC was determined using the MBEC
assay, formerly known as the Calgary Biofilm Device, developed by Innovotech. In this
instance, the MBEC was defined as the amount of antimicrobial required to eradicate 100%
of detectable biofilm after being grown in the MBEC device. To grow the biofilms within
this device, 150 uL of on containing a concentration of 105 cells/mL were inoculated
into each well of a 96-well plate. A lid containing 96 pegs was placed onto the plate and
incubated for 24 hours at 370 C while being shaken at 110 rpm. Biofilms developed on the
surface of the polystyrene pegs within the 96-well plate. After 24 hours, each peg contained
between 105 and 106 cells in well-established biofilms. The lid with pegs was transferred to a
96-well plate that contained 200 uL of varying trations of the compound and was
incubated at 37° C for an additional 24 hours. The plate was then sonicated, and the biofilms
quantified using a 10-fold on series to determine the MBEC. Data are presented in
Table 1.

[0360] The fourth test that was performed was the ive biofilm eradication
concentration (EBEC). To determine the EBEC, biofilms ofMRSA and P. aeruginosa
ATCC 27853 were grown on the surface of PEEK membranes using a previously established
protocol. Briefly, 500 mL of brain heart infusion (BHI) broth were inoculated with 105
cells/mL of MRSA or P. nosa. BHI broth was placed into a membrane biofilm reactor
and placed on a hot plate set at 34° C for 24 hours with a stir bar rotating at 130 rpm.
Following the initial r growth period, a 10% BHI broth solution was flowed through
the reactor at a rate of 6.944 mL/min for another 24 hours. After 48 hours of growth, each
PEEK membrane had biofllm grth on it. In this experiment, there were ~2 x 1011 cells of
MRSA per PEEK membrane and ~2 x 1010 cells ofP. aeruginosa per PEEK membrane. The
EBEC was defined as the tration of the compound that was required to eradicate all
detectable amounts (100%) of bacteria within the s. Data are presented in Table 1.
In addition to determining the antimicrobial efficacy of the compound, an initial test
was performed to determine its hemolytic nature. To do so, the nd was suspended in
concentrations of 100 ug/mL, 50 ug/mL and 25 ug/mL. Twenty uL of each concentration
was placed onto the surface of Columbia blood agar and incubated at 37° C for 24 hours.
Results indicated that none of these concentrations displayed tic activity.
Initial tests based on visual observation were performed to determine the ability of
the compound to disperse biofllms. This was done by observing the biofilms ofMRSA and
P. aeruginosa that had grown on the surface ofPEEK membranes after they had been placed
in three separate concentrations of the compound (300 ug/mL, 200 ug/mL and 100 ug/mL).
Biofilms were observed every 30 s to see if they ted from the PEEK membrane.
Within 2 hours, biofilms began to separate from the PEEK membranes, by 4 hours
approximately half of the biofilms had separated and by 24 hours, all detectable amounts of
biofilm had separated from the PEEK membrane. For comparison, it is the understanding of
the inventors hereof that this dispersal effect is not seen with other antimicrobials such as
chlorhexidine gluconate, glutaraldehyde, or honium chloride.
The MIC, MBEC and EBEC ofvancomycin were also determined for comparison,
and the results are presented in Table 2.

MIC Analysis
[0364] To determine the MIC of polyamine compounds, the protocol described herein was
used. The MIC is defined as being the concentration of antimicrobial (in ug/mL) ed to
reduce the number of bacteria in a solution from 105 colony forming units (CFU)/mL to 102
CFU/mL in a 24-hour period.
In brief, a 0.5 McFarland of each bacterial isolate was made. A 0.5 and is a
measure of turbidity in a liquid sample that contains approximately 1 x 10A8 CFU/mL. The
0.5 McFarland rd was diluted in cation adjusted Mueller Hinton Broth (CAMHB), and
50 [LL of broth were added to a well of a 96-well plate. In addition, 50 uL of CAMHB that
contained a desired concentration of antimicrobial were also added to the well for a final
volume of 100 [LL and a final concentration of approximately 5 x 104 CFU/well (which
equated to imately 5 x 105 CFU/mL). Each well contained a desired amount of
polyamine compound in order to experimentally determine the MIC. Each 96-well plate was
incubated at 37° C for 24 hours. The contents of each well were plated on tryptic soy agar
(TSA). TSA plates were ted for 37° C for 24 hours after which the number of CFU
were counted and used to calculate the CFU/mL that remained after re to varying
concentrations of compound. This procedure was repeated n=8 times for each concentration
of antimicrobial. The concentration of polyamine nd that reduced bacteria from 105
CFU/mL to 102 CFU/mL in 24 hours was considered the MIC.
MICs from representative polyamine compounds as well as select antibiotics are
ed in Table 3A and 3B. Consistent with what was mentioned previously, these data
te that with an increase in the number of polyamine chains attached to a lipophilic
ne, the MIC is lowered, indicating it has greater antimicrobial ial. CZ-7 has one
chain ofnorspermidine attached, CZ-25 has two chains ofnorspermidine and CZ-51 and CZ-
52 have three chains attached.

To determine the MBEC of each polyamine compound, the MBEC Inoculation Tray
by Innovotech, formerly known as the Calgary biofilm device, was used. Within this device,
biofilms grow on the surface of polystyrene pegs, 96 of which are ed to a lid. These
pegs are inserted into a flat bottom 96-well plate. In this instance, the MBEC of a molecule
was defined as the concentration of compound (in ug/mL) required to reduce 105 or 106
CFU/peg (biofilm levels varied by e) to 102 CFU/peg in a 24-hour period.
Following the manufacturer's guidelines, biofilms were grown on the surface of
each peg by first making a 0.5 McFarland of each isolate. The 0.5 McFarland was diluted
1:100 in CAMHB. Into each well of a flat bottom 96-well plate, 150 uL of broth were
ed. The plate was shaken at 100 rpm for 24 hours (P. aeruginosa and A. baumannii) or
48 hours (MRSA). The pegs were then placed into a te flat bottom 96-well plate for 10
seconds with 200 uL of phosphate buffered saline (PBS) in each well to remove nonadherent
cells. The lid was then placed into a 96-well plate that contained g concentrations of
antimicrobial with 200 uL per well. The plate was incubated for 24 hours at 37° C after
which time 100 uL of broth were plated on TSA. TSA plates were incubated 24 hours at 370
C and the number of CFU counted to calculate the CFU/peg. In this instance, the MBEC was
defined as the concentration of antimicrobial required to reduce 105 or 106 CFU/peg to 102
CFU/peg in a 24 hour period.
[0369] MBEC data are presented in Table 4. Similar to the MIC data, the trend of
sing antimicrobial activity by increasing the number ofpolyamine chains ed to a
backbone was confirmed against low number s.
EBECAnalysis
In addition to determining the MIC and the MBEC ofpolyamine compounds against
planktonic bacteria and low number biofilms, our group wanted to determine the efficacy of
polyamine compounds t high number biofilms. To do so, biofilms were grown on the
surface of polyetheretherketone (PEEK) membranes using a membrane biofilm reactor. This
reactor is similar to the CDC biofilm reactor, but rather than growing biofilms on coupon
surfaces, the reactor was modified to hold PEEK membranes. In short, to grow biofilms
within this system, 500 mL of brain heart infusion (BHI) broth were inoculated with 1 mL of
a 0.5 McFarland. The reactor was placed on a hot plate set at 34° C and the ia were
grown under batch conditions for 24 hours. ing this protocol, biofilms typically grow
to 109 CFU/PEEK membrane. each PEEK membrane has high number biofilms A solution
of 10% BHI was then flowed through the reactor at a rate of 6.94 mL/min for an additional
24 hours. PEEK membranes were then removed and placed into 2 mL of CAMHB that
contained a desired concentration of polyamine compound or antibiotic. The EBEC was
defined as the concentration of antimicrobial ed to reduce a biofilm from approximately
109 CFU/PEEK membrane to approximately 102 CFU/PEEK membrane in a 24-hour period.
EBEC data are presented in Table 4. One of the most striking results was the
difference in efficacy between CZ-52 and ycin. At 25,000 ug/mL, vancomycin did
not have the ability to reduce biofilms of MRSA by even 1 logo unit. In contrast, at 250
ug/mL CZ-52 was able to reduce MRSA biofilms by greater than 7 logo units in a 24-hour
period.
Example 4
Release OfPolyamz'ne Compoundsfrom Carrier Products
[0372] To collect proof-of-concept/preliminary data that r(s) will release these
products in sufficient amounts to have antimicrobial efficacy, a polytherapy formula was
ed. A Vanicream—based cream from the University of Utah compounding cy
was used as the formulation base, and active ingredients were added to create a cream with
final concentrations of 0.25% CZ-52, 0.25% CZ-25 and 0.1% Polymyxin B sulfate. To test
its efficacy, 0.5 McFarland standards of MRSA, P. aeruginosa, and A. baumannii were made,
and a lawn of each isolate was spread on Columbia blood agar. Approximately 20 mg of
cream was placed in the center of each lawn. The plates were incubated 24 hours at 37° C.
Zones of clearing in each experiment ed a preliminary indication that the
antimicrobials will elute out of the cream in sufficient quantities to eradicate each bacterial
isolate (). Notably, the cream alone (negative control) created no zones of inhibition,
and polyamine nds used alone in the cream likewise created zones of clearing. In
broth samples, the polytherapy composition has shown similar results by eradicating all
detectable amounts of each ial isolate after they had been grown as biofilms on PEEK
membranes with approximately 109 CFU/PEEK membrane. In short, these data indicate that
the polytherapy antimicrobial agents will elute out of carrier product(s) and eradicate
bacteria, including those in biofilms.
Biofilm Dispersion
CZ—25 and CZ-52 were tested for their ability to disperse s ofMRSA and P.
aeruginosa. To test for dispersion, s of each isolate were grown on the e of
commercially pure titanium (Ti) coupons (l/2” diameter x l/8” height) in a CDC biofilm
reactor. The growth conditions for this reactor were the same as those for the membrane
biofilm reactor. After biofilms were grown for 48 hours, each Ti coupon was aseptically
d and placed into 2 mL of CAMHB for 2 hours. The CAMHB had a final
concentration of 0.25% (2.5 mg/mL) CZ-25 or CZ-52. Each nd was tested n=3 times.
Following the 2-hour exposure, each coupon was fixed in 0.25% glutaraldehyde for
24 hours, dehydrated using ascending concentrations of ethanol (70%, 95%, 100%) with 3x
min. changes and desiccated. One side of each coupon was carbon coated and imaged
using a JEOL ISM-6610 SEM to ly observe the surface of the coupons and determine
the ability of polyamine compounds to disperse biofilms compared to positive controls that
had no treatment.
When compared to untreated controls, data have indicated that CZ-25 and CZ-52
have the ability to disperse biofilms from the e of a material () such that a
yer of cells or reduced communities remain.
The MRSA ms were grown on the surface of um (Ti) coupons using a
CDC biofilm reactor. For this reactor, an initial inoculum of N5 x 10A5 cells/mL were put
into 500 mL of brain heart on (BHI) broth. The reactor was placed on a hot plate set at
34 C for 24 hours and the bacteria were allowed to grow in batch culture. For an additional
24 hours, 10% BHI broth was flowed through the reactor at a rate of 6.94 mL/min. After the
48-hour growth period, the coupons were cally removed and placed into 2 mL of cation
adjusted Mueller Hinton broth (CAMHB) for 2 hours. Digital images of the biofilm
dispersion process were collected after 30 minutes of exposure to polyamine compounds.
After 2 hours, the same procedure as above was used to fix the biofilms and image them by
SEM.
Digital images of MRSA biofilms being dispersed from the surface of the Ti coupon
also help to highlight the dispersive ability of CZ-25 ().
Data has also been collected to determine the dispersive capacity amine
compounds against vorax borkumensz's, an oil-eating bacterium (FIGS. 19 and 20).
For the dispersal data with the Alcanivorax borkumensis, 1/2 inch diameter
galvanized steel pipe that was approximately 6 inches long was purchased. Two strips of
galvanized sheet metal were cut into 1/2 cm x 2 cm strips, and two of those were placed into
the pipe. The pipe was connectedto silicone tubing, and marine broth was run through the
pipes with an um of 5 x 10A5 cells/mL. The broth was flowed through the pipes at a
rate of 6.94 mL/min using a peristaltic pump. Biofilms were grown on the surface of the
galvanized steel for 48 hours, then exposed to polyamine compounds or aldehyde for
two hours. The strips of galvanized steel were then removed, fixed in 0.25% glutaraldehyde
for 2 hours (those that had already been exposed to glutaraldehyde were not fixed twice), and
dehydrated in ascending concentrations of l (70%, 95%, 100%) with 3x 10 minute
exchanges of each. Lastly, the strips were carbon-coated and were imaged using a JEOL
JSM-6610 ng on microscope (SEM) with a lanthanum hexaboride (LaB6)
filament.
e 6
One of the most promising s of polyamine compounds is that preliminary data
suggests that these compounds address the characteristics of biofilms that have made them
resistant to antibiotic treatment. Specifically, polyamine compounds have potent
crobial activity against very high inocula of bacteria and kill bacteria in a rapid fashion.
Without meaning to be bound by theory, initial characterization suggests that polyamine
compounds are membrane-active, meaning they are cific in nature. This nonspecific
action reduces the ial for bacteria to upregulate their defense mechanisms and reduces
the risk of resistance development. From the data collected to date, it does not appear that
polyamine compounds are limited to eradicating bacteria that are in log-phase growth as
indicated by their activity against bacteria in the biofilm phenotype. Bacteria in a biofilm
have reduced metabolic activity, which is one of the primary contributing factors that allows
biofilms to resist traditional antibiotic therapy. Typically, antibiotics affect bacteria in log-
phase growth. Finally, ine compounds have the ability to disperse biofilms while
demonstrating antimicrobial kill. By sing and killing bacteria in a biofilm, it is
hypothesized that polyamine compounds interrupt water channels and the community as a
whole, allowing for distribution of polyamine compounds to a greater number, if not all, of
the cells within a biofilm.
A key aspect ofpolyamine compounds is the process by which they are synthesized
to provide triple action against bacteria and biofilms. The ability to synthesize antimicrobial
compounds with specific activity t biofilms is cant. Traditional approaches to
discovering or ping antibiotics has primarily been done through cumbersome, high—
throughput screening methods with limited results wherein perhaps 1 in 1,000 compounds
may be of interest. Using the below method, our group was able to produce a lead product
after synthesizing approximately 20 compounds.
Organisms residing in biofilms present a complex extracellular matrix of
polysaccharides (exopolysaccharides) and proteins. As a result of this complex ,
nutrient limiting conditions may exist that alter the normal or planktonic metabolic state. As
stated above, this produces to a reduced efficacy of ional antibiotic agents, rendering
them up to 1,000 times less active. A hallmark of these exopolysachharides is the
presentation of acidic es from repeated glucoronic acid motifs and pyruvate derived
acetals. A recent study by Losick and co-workers demonstrated that the simple polyamines
spermine and norspermidine were naturally occurring inhibitors of biofilm ion,
endogenously produced at high concentrations (5 0-80 uM) in response to nutrient limiting
conditions and waste accumulation in mature pellicles. In this study they were able to
demonstrate that norspermidine could inhibit biofilm formation at 25 uM and showed that at
similar concentrations it could disperse the exopolysaccharide component of the matrix but
I5 not the protein ent. This does suggest, however, that these agents might be capable of
disassembling established biofilms. Interestingly, spermidine was only active at much higher
trations (~ 1 mM) leading them to propose a rationale for this activity in the ability of
the polyamines to engage the acidic residues in the matrix at regular intervals.
Given the lack of activity for dine vs. norspermidine, it is interesting to note
that many secondary metabolites containing the polyamine frameworks have been fied
as potent antimicrobials against planktonic bacteria. Most y squalamine, which
ns a spermidine tail, and the related natural product incorporating a spermine tail show
potent antimicrobial activity against Gram-positive and Gram-negative bacteria ().
Lysine-rich cationic peptides such as magainin and pexiganin are also potent anti-microbials
against a wide range of organisms and have been developed as topical crobials for the
ent of diabetic foot ulcers.
Ofnote is the incorporation of hydrophobic and cationic residues that are present in
these antimicrobial “kill” compounds, without adhering to the strict en bond donor-
acceptor pattern of the biofilm disruptors. Thus, an l study was made to investigate the
utility of combining a simplified hobic backbone with a cationic tail that might impart
molecules with the ability to inhibit biofilm formation, disrupt established biofilms and kill
the emerging planktonic bacteria. The study began with the synthesis of benzylic substituted
polyamines (). The synthesis of opropane substituted nes is
straightforward to provide CZ-4, 12,32 from the known mono-Boc protected diaminopropane
and the commercially available aldehydes (benzaldehyde, isopthalaldehyde or 1,3,5-
benzenetricarboxaldehyde). This step synthetic procedure ds via reductive
amination and acidic removal of the Boc group. Of note is that no purification is required
until a final recrystallization of the HCl salt. The norspermidine series (CZ-7,25,52) can be
prepared in a similar manner from the mono-Boc protected norspermidine. Of note is that no
purification is required until a final recrystallization of the HCl salt, which allows easy
preparation of these compounds on at least a ~ 10 g scale.
[0386] In some cases, increasing number of polyamine chains on the hydrophobic
backbone systematically increases activity. For example, with a single chain of
diaminopropane added to a benzyl backbone (CZ-4, ), the minimum inhibitory
concentration (MIC; as defined by the Clinical and Laboratory Standards ute (CLSI))
against MRSA is greater than 1,200 ug/mL, whereas two chains se the MIC to 300
ug/mL ) and three chains reduce it further to 45 ug/mL (CZ-32). Similarly, with a
single chain of norspermidine attached to a benzyl backbone (CZ-7, ), the MIC
against MRSA is greater than 1,200 ug/mL. By adding a second chain of norspermidine
(CZ-25), the MIC is 45 ug/mL. With a third chain of norspermidine attached (CZ-52), the
MIC becomes 3 ug/mL.
[0387] Concurrently to the other goals of this project, a focused synthetic effort will
continue to exploit this trend and generate related chemotypes with increased efficacy (e. g.,
compounds with four polyamine ). This is expected to be accomplished, for example,
via Pd(II) mediated dimerization of 5-bromoisopthalaldehyde followed by reductive
ion ().
Example 7
Evaluation ofBiofilm ation and Removal Chemistries
A series of experiments is ted to investigate the impact ofbiofilm
ation and removal chemistries on mimetic multispecies biofilms commonly associated
with anthropogenic heating and cooling water systems.
[0389] The criteria for success is to demonstrate that these chemistries:
(1) Remove a multispecies biofilm from a copper, mild steel, galvanized steel, and
stainless steel substrate to a greater extent than that which can be achieved by the existing
water treatment tries.
(2) Do not aggressively corrode the metal ates when used in an optimum
concentration.
(3) Avoid material ibility issues with the existing treatment chemicals used to
minimize scale formation and prevent corrosion of the metal parts of the anthropogenic
heating and cooling system.
Biofilm Generation on the Metal Coupons
[0390] Normally, monoculture bacteria ing to the Pseudomonas genus have been
used to investigate the physical and mechanical properties of biofilm on different heat
exchanger es and substrates under changing flow conditions. However, to more
accurately represent conditions that would be found in the real environment, a mixture of
Pseudomonasfluorescens and Pseudomonas putida together with a 0.1% mixture ofNCH
3010 Bacillus subtilis, NCH 3032 Bacillus subtilis, NCH 3016 Bacillus licheniformis, and
NCH 3040 Bacillus thuringiensis all of which are naturally occurring soil bacteria is used.
The microorganisms will be provided in pellet form from Eco-Bionics, and each pellet
contains a starter e and riate nutrients that produce actively growing bacteria
with the addition of water.
[0391] The experimental test procedure is a modified version of the single tube method.
Biofilm are grown on the metal coupons using a m reactor designed around a
continuous stir tank reactor (). Prior to operation the reaction chamber and the
individual components are disassembled, soaked in a 10% bleach solution, then scrubbed in
hot soapy water and rinsed in distilled water. Once cleaned, the stir tank reactor is d
with 2 liters of DI water, and 20 g of the Free Flow pellets will be added to the water.
Coupons are placed onto the coupon holding rods, which is then inserted into the Free Flow
pellet on. The reactor runs for 6 days with the Free Flow solution being replaced every
2 days.
Biofilm growth isvisually observed and documented photographically. To quantify
the presence of viable microorganisms within the biofilm structure formed on the metal
coupons (see for an example of the typical biofilm formed on the substrate) the
biofilm d coupons is removed from the reactor and lightly rinsed with sterile buffer to
remove any loose debris from the surface. The coupons are then transferred to a container
with 40 ml of Phosphate buffer on (PBS) and vortexed for 30 sec then placed in a
sonication bath (Branson model 3200) for 30 sec. After sonication, the container with the
buffer and coupon is d and vortexed again for 30 sec before being returned to the
sonication bath for an additional 30 sec of processing. A third and final vortexing step
ensures that the d biofilm will be thoroughly removed. After processing to remove the
bioflim the PBS solution will be serially diluted onto tryptic soy agar (TSA) plates which will
be incubated at 30 0C for up to 36 hours before being enumerated.
The biofilm coupons are exposed to a high, medium, and low concentration of the
product (based on the recommended dosing rates) for a prescribed time. After treatment, the
coupons are d, and the eluant and treatment solutions are assayed to enumerate viable
bacteria A standard dispersant used for biofilm removal, together with a standard biocide
(oxidizing and non-oxidizing) used at the recommended label use concentrations, are used as
controls.
Corrosion Testing
ent solution of the same concentrations used in the ments above is
prepared with standard corrosion tor products and m deposit products in regular
tap water and tested in a standard corrosion test. The solution is added to a treatment tank
that is stirred continually for two weeks, after which the coupons are removed and analyzed
for ion using standard corrosion test methods. Corrosion rates of less than 3.0 mpy for
mild steel and 0.2 mpy for copper are considered non corrosive. A standard dispersant used
for biofilm removal together with a standard biocide (oxidizing and non-oxidizing) used at
the recommended label use concentrations are used as controls.
Conclusions
[0395] We have been able to determine minimum s of our polyamine compounds
that will have activity against biofilms of P. aeruginosa. In general, the polyamine
compounds do better against Bacilli than P. aeruginosa, so what is active against P.
aeruginosa is likely active against Bacilli.
These formulas are made in PBS, water or broth.

Methodsfor MIC, MBEC andEBECAnalysis
To determine the MIC of the compounds of the present invention the ing
procedure was used.
A 0.5 McFarland of A. baumanniz’ is made. A 0.5 McFarland is a measure of
turbidity in a liquid sample that ns approximately 7.5 x 107 CFU/mL. The 0.5
McFarland standard is diluted in CAMHB and 50 [LL of broth is added to a well of a 96-well
plate. In addition, 50 [LL of CAMHB that ns a desired concentration of antimicrobial is
added to the well for a final volume of 100 uL and a final concentration of approximately 5 x
104 CFU/well (which equates to approximately 5 x 105 CFU/mL). Each well contains a
desired amount of CZ nd in order to experimentally determine the MIC. Each 96-
well plate is incubated at 37° C for 24 hours. The contents of each well is plated on tryptic
soy agar (TSA). TSA plates is incubated at 37° C for 24 hours after which the number of
CFUs is d and used to calculate the CFU/mL that remain after exposure to varying
concentrations of compound. This procedure is repeated n=8 times for each concentration of
antimicrobial. The concentration of CZ compound that reduces bacteria from 105 CFU/mL to
102 CFU/mL in 24 hours is considered the MIC.
To ine the MBEC, the MBEC Inoculation Tray by Innovotech, formerly
known as the Calgary biofilm device, is used. Within this device, biofilms grow on the
surface of polystyrene pegs, 96 of which are attached to a lid. These pegs are inserted into a
flat bottom l plate. In this instance, the MBEC of a molecule is defined as the
concentration of compound required to reduce approximately 106 CFU/peg to imately
102 CFU/peg in a 24-hour period.
Following the manufacturer's guidelines, ms are grown on the e of each
peg by first making a 0.5 McFarland ofA. baumanm’z‘. The 0.5 McFarland is diluted 1:100 in
CAMHB broth. Into each well of a flat bottom 96-well plate, 150 uL of broth is pipetted.
The plate is shaken at 100 rpm for 24 hours. The pegs are placed into a separate flat bottom
96—well plate for 10 seconds with 200 uL ofphosphate buffered saline (PBS) in each well to
remove nonadherent cells. The lid is placed into a 96-well plate that contains varying
concentrations of antimicrobial with 200 uL of broth per well. The plate is incubated for 24
hours at 37° C after which time 100 uL of broth is plated on TSA. TSA plates is incubated
24 hours at 37° C and the number of CFU counted to calculate the CFU/peg.
In addition to determining the MIC and the MBEC of compounds against planktonic
bacteria and low number biofilms, the efficacy of the compounds of the invention against
high number biofilms is determined. To do so, biofilms are grown on the surface ofPEEK
membranes using a membrane biofilm reactor (Williams, D. L., Haymond, B. S. &
Bloebaum, R. D. Use of delrin plastic in a modified CDC biofilm reactor. Res JMicrobiol 6,
425-429 (2011); Williams, D. L., Woodbury, K. L., Haymond, B. S., Parker, A. E. &
Bloebaum, R. D. A d CDC biofilm reactor to produce mature biofilms on the surface
ofPEEK membranes for an in vivo animal model application. Curr Microbiol 62, 1657-1663
(2011); Williams, D. L. et al., In Vivo Efficacy of a Silicone - Cationic Steroid Antimicrobial
g to Prevent Implant-Related Infection. Biomaterials 33, 656 (2012); Williams,
D. L. et al., mental model ofbiofilm implant-related osteomyelitis to test combination
erials using biofilms as initial a. J Biomed Mat Res A 100, 1888-1900 (2012)).
This reactor is similar to the CDC biofilm reactor, but rather than growing biofilms on
coupon surfaces, the reactor was modified to hold PEEK membranes. In short, to grow
biofilms within this system, 500 mL of brain heart ll’lqulOl’l (BHI) broth is inoculated with 1
mL of a 0.5 McFarland. The reactor is placed on a hot plate set at 340 C and the bacteria
grown under batch conditions for 24 hours. A solution of 10% BHI will then be flowed
through the r at a rate of 6.94 mL/min for an additional 24 hours. ing this
protocol, biofilms typically grow to 109 CFU/PEEK membrane. PEEK membranes is
removed and placed into 2 mL of CAMHB that contain a desired concentration of the test
compound. The EBEC is defined as the concentration of antimicrobial required to reduce a
biofilm from approximately 109 CFU/PEEK membrane to approximately 102 CFU/PEEK
membrane in a 24-hour .
MIC, MBEC and EBECAnalysis
To determine the MIC of the test compounds and traditional antibiotics, a protocol
which defines the MIC as being the concentration of crobial required to reduce the
number of bacteria in a solution from 105 colony g units (CFU)/mL to 102 CFU/mL in
a 24-hour period. MICs for tests compounds as well as for select antibiotics are provided in
Table 4. Consistent with what was mentioned previously, these data indicate that, with an
se in the number of polyamine chains attached to a lipophilic backbone, the MIC is
lowered, indicating it has greater antimicrobial potential. CZ-7 has one chain of
norspermidine attached, CZ-25 has two chains of norspermidine, and CZ-52 has three chains
attached ().
The trend of increasing antimicrobial activity by increasing the number of
polyamine chains attached to a backbone while also modulating the hydrophobicity of that
backbone shows promising activity t A. baumannii, more specifically in the case of
CZ-58 (). The analysis below shows that compounds of the invention have increased
efficacy relative to current ies (e. g., polymyxin B).
MBEC data were collected using the MBEC Inoculation Tray by Innovotech. The
MBEC was defined in these preliminary results as the concentration of antimicrobial required
to reduce 105 or 106 CFU/peg to 102 CFU/peg in a r period. MBEC data are presented
in Table 4.

EBEC data showed striking differences in efficacy between CZ-52 and vancomycin (Table
4). At 25,000 ug/mL, vancomycin did not have the ability to reduce biofilms ofMRSA by
even 1 logo unit. In contrast, at 250 ug/mL CZ-52 was able to reduce MRSA biofilms by
greater than 7 loglo units in a 24-hour period. gh the MIC of CZ—58 was lower against

only ~l3x greater than the MIC. gh the MIC of CZ-58 was “high” compared to MICs
of traditional antibiotics, the efficacy against biofilms was promising.

Biofilm Dispersion
The compounds of the present invention such as CZ 25, CS—58 and CS-52 have
excellent sal characteristics. To test for dispersion, biofilms of each isolate were grown
on the surface of commercially pure titanium (Ti) s (1/2” diameter x 1/8” height) in a
CDC biofilm reactor. The growth conditions for this reactor were the same as those for the
membrane biofilm reactor. After biofilms were grown for 48 hours, each Ti coupon was
aseptically removed and placed into 2 mL of cation adjusted Mueller Hinton broth (CAMHB)
for 2 hours. The CAMHB had a final concentration of 0.25% (2.5 mg/mL) CZ-25 or CZ-52.
Each compound was tested n=3 times.
Following the 2-hour exposure, each coupon was fixed in 0.25% glutaraldehyde for
24 hours, dehydrated using ascending concentrations of ethanol (70%, 95%, 100%) with 3x
min. changes and ated. One side of each coupon was carbon coated and imaged
using a JEOL ISM-6610 SEM to directly observe the surface of the coupons and determine
the ability of CZ compounds to disperse biofilms compared to ve controls that had no
treatment. When compared to untreated controls, data have ted that CZ—25, CZ—52 and
CZ-58 have the ability to disperse biofilms from the surface of a material () such that
a monolayer of cells or reduced communities .
[0409] provides SEM images of Ti coupons with MRSA biofilms exposed to CZ-
(left), CZ—52 (middle) or water only (right). CZ-25 and CZ—52 demonstrated the ability to
disperse the majority of biofilms such that a monolayer of cells remained on the surface of
the Ti. Those samples d with water only had biofilm communities that remained in all
areas of the coupons.

Step 2: N1,N1'-([1,1'-Bz'phenyl]-3,5-diylbis(methylene))bis(N3-(3-
(isobutylamino)pr0pyl)pr0pane-I,3-dz'amine). [1,1'-Biphenyl]—3,5-dicarbaldehyde (3.03 g,
14.4 mmol) and MeOH (60 mL) were added to a round—bottom flask. To the solution was
added N1-(3-aminopropyl)-]\]3-isobutylpropane-1,3-diamine (5.40 g, 28.8 mmol), and the
reaction mixture was stirred at rt for 24 h. Sodium dride (0.55 g, 14.4 mmol) was
added, and the reaction mixture was stirred for 2 h. The reaction mixture was concentrated
under reduced pressure to afford a white solid. Aqueous NaOH (10%, 50 mL) was added,
and the reaction mixture stirred for 30 min. The solution was extracted with CHC13 (3 x 75
mL). The c layers were combined, dried over Na2S04, filtered, and trated under
reduced pressure to afford a clear oil which was used without further purification.
Step 3; N1,N1'-([1,1'-Biphenyl]—3,5-diylbis(methylene))bis(]\]3-(3-

from step 2 was added methanolic HCl (75 mL, 2.0M). The resulting white solid was
collected by vacuum ion and washed with minimal MeOH and EtzO and stored under
high vacuum to afford the desired product (9.3 g, 89%) as a white solid.

(50 mL). The layers were separated and the aqueous layer was extracted with EtOAc (50
mL). The combined organics were dried over Na2S04, filtered, and concentrated under
reduced pressure to afford the desired product which was used without further purification.
Step 2: Ethylbut0xy)-I,3-phenylene)dimethanol. To a solution of dimethyl 5-
ylbutoxy)isophthalate (0.62 g, 2.10 mmol) in THF (20 mL) was added LiAlH4 (0.24 g,

HCl (10 mL) and extracted with EtzO (2 x 25 mL) and EtOAc (2 x 25 mL). The combined
organics were dried over Nast4, d, and concentrated under reduced pressure to afford
the desired product which was used without further purification.

Antimicrobial activity ofpolyamines in agar media
A 0.5 McFarland standard of each bacteria was made, then individual lawns of
bacteria spread onto the surface of tryptic soy agar (TSA). 500 uL of the suspended gel were
placed on the center of each lawn. Plates were incubated at 37 C for 24 hours, then imaged.
Images of the resulting gels are shown in FIGS. 30A to 301 show the effects of the
polyamines CZ-86, CZ-100, and CZ-110 on various bacterial cell cultures. The data shown
indicated that when the polyamine compounds were mixed with the gel, the compounds
diffused out of the gel and created zones of inhibition in the bacterial lawns. The gel alone
showed no signs of crobial activity (B).
The hydrogel that was used for those images is a LifeCore gel with 1% sodium
hyaluronate (1% Sodium Hyaluronate Solution Part #82). The CZ compound was suspended
in water at 1% (w/w) concentration and ed with the LifeCore gel 1:1 for a final
product that contained 0.5% sodium hyaluronate and 0.5% CZ compound.

Acceptance Criteria: The negative control must produce a ted hemolytic
index of less than 2%. The positive control must produce a corrected hemolytic index of
greater than 5%.
Procedure: The PBS used in testing was calcium and magnesium free. The method
has been validated using human blood from one donor. This is in compliance with ISO
10993-4 which states due to differences in blood activity, human blood should be used where
possible. Furthermore, pooling unmatched human blood from multiple donors may cause red
blood cell agglutination which in turn could cause hemolysis; this supports the use of a single
donor.
The blood was drawn using vacutainers containing 0.1 M sodium citrate at a ratio of
9:1 (3.2% anticoagulant to blood). The blood in this test was used within four hours ofblood
draw. The ted blood was refrigerated until g was performed.
A hemoglobin standard was d with Drabkin's reagent to give solutions at
concentrations of 0.80, 0.60, 0.40, 0.30, 0.20, 0.10, 0.02, and 0.01 mg/ml. These solutions
were allowed to stand at room temperature for a minimum of five minutes. The absorbance
was read on a spectrophotometer at 540 nanometers (nm). A standard curve was determined
with the absorbance values and the standard concentrations of hemoglobin.
Human blood was centrifuged at 700-800 x g for 15 minutes. A 1 mL aliquot of the
plasma was added into 1 mL of n's reagent, and placed at room temperature for a
minimum of 15 minutes. The absorbance was read on a ophotometer at 540 nm. The
hemoglobin concentration was determined from the standard curve and then multiplied by a
factor of 2 to obtain the total plasma free hemoglobin. The plasma free hemoglobin was less
than 2 mg/mL (actual value 0.221 mg/mL). A 20 uL aliquot of blood was added to 5 mL of
Drabkin's reagent in duplicate and allowed to stand at room temperature for a minimum of 15
minutes. The absorbance was read on a spectrophotometer at 540 nm then multiplied by 251
to account for the dilution.
[0564] Based on the plasma hemoglobin and the blood absorbance against Drabkin's
reagent, the blood was diluted out to 10 :: 1 mg/mL with PBS. To verify the blood on, a
300 [LL t of this blood was added to 4.5 mL of Drabkin's reagent in cate and
allowed to stand at room temperature for a minimum of 15 minutes. The absorbance was
read on a spectrophotometer at 540 nm then multiplied by 16 to account for the dilution.
[0565] Glass test tubes were labeled appropriately. Both samples were prepared the same
way. The samples were allowed to thaw prior to testing. To each test tube, 7 mL of the test
article and 1 mL of the diluted blood were added. The controls consisted of the appropriate
amount of control material, 7 mL of PBS and 1 mL of blood. Three tubes were prepared for
each test article and control. The tubes were ted at 37 :: 2°C for 3 hours :: 5 minutes.
Tubes were gently inverted twice at 30 minute intervals throughout the incubation period. A
non-hemolytic ve control, a hemolytic ve control and a PBS blank were included.
After incubation, test articles were centrifuged at 700-800 K g for 15 minutes and 1
mL of the supernatant fluid was ed with 1 mL of Drabkin's reagent and allowed to
stand at room temperature for a minimum of 15 minutes. Following the fugation phase,
the supernatant of both test articles visually appeared clear and were particulate free. The
PBS blank and the negative control supernatant visually appeared clear and were particulate
free. The supernatant of the positive control visually appeared red and were particulate free.
The test articles and controls were read at 540 nm in a spectrophotometer.
The hemolytic index (percent hemolysis) was interpreted using the following
equation:
Hemoglobin ed (mg/mL)
H emo y 1C1 t' I 11dex —_ x 100
obin t (mg/mL)
Where: Hemoglobin Released (mg/mL) = (Optical y x X Coefficient+ nt) x 16
Hemoglobin Present (mg/ml) = Diluted Blood 10 :: 1 mg/mL
[0568] The corrected hemolytic index was calculated by subtracting the hemolytic index of
the PBS blank solution from the hemolytic index of the test article and controls.
The test article is compared to the negative control by cting the hemolytic
index of the negative control from the hemolytic index of the test article.
