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); Nordmann et al., The real threat ofKlebsiella pneumoniae carbapenemase—producing bacteria, Lancet Infect Dis 9, 228-236 (2009); Aloush et al., Multidrug-resistant 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 (2006); Huj er et al., Analysis ofAntibiotic Resistance Genes in Multidrug—Resistant 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 System ofPseudomonas nosa: Involvement ofthe Antibiotic-Inducible PA54 71 Gene Product, Journal of Bacteriology 188, 1847-1855 (2006); Tran et al., Heat-Shock Protein ClpL/HSPI00 Increases Penicillin nce in ococcus pneumoniae, Advances in Oto-rhino-laryngology 72, 126-128 (2011); Livorsi et al., nce Factors ofGram- 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. [0016a] According to an embodiment, there is provided a non-therapeutic method for dispersing or killing a biofilm, the method comprising a step of contacting the biofilm with an anti-biofilm composition, y sing or killing the biofilm; wherein the anti-biofilm composition comprises a biocidal polyamine nd selected from the group consisting of Ra Ra A1 A5 A1 A5 A3 Ra , Ra A3 Ra , and a salt thereof; wherein: A1, A2, A3, and A5 are each an independently selected CR5; each Ra is an independently selected group of Formula V: R1a R1b N R2c R4 Rm R2d R3 ; each R1a and R1b is a member ndently selected from hydrogen and alkyl; each R2a, R2b, R2c and R2d is a member independently ed from the group consisting of hydrogen, alkyl, and fluoroalkyl; 16584576_1 (GHMatters) P41348NZ01 each R3 is a member independently selected from the group consisting of -Z1-R4, -Z1-Y1-R4, -Z1-Y1-Y2-R4, and -Z1-Y1-Y2-Y3-R4; each Y1, Y2, and Y3 is an independently selected group of Formula IA: Rm R2d each Z1 and Z2 is an independently selected -N(R4)-; each Rm is -CH2-; each m is an integer independently selected from 1 to 2; each R4 is a member ndently selected from the group consisting of hydrogen, alkyl, fluoroalkyl, alkenyl, l, aryl, cycloalkyl, heteroaryl, arylalkyl, cycloalkylalkyl, and heteroarylalkyl; or, alternatively, for an -N(R4)2 group, one of the two R4 in the group is a member selected from the group consisting of -(CO)OR6a, -(CO)N(R6a)(R6b), and -C(NR6a)N(R6b)(R6c); or, alternatively, for an -N(R4)2 group, the two R4 groups join to form a heterocyclic ring; each R5 is a member independently selected from the group consisting of hydrogen, alkyl, yl, alkoxy, aminoalkoxy, alkylamino, alkylaminoalkoxy, alkenyl, alkynyl, aryl, aryloxy, arylamino, cycloalkyl, cycloalkoxy, cycloalkylalkoxy, cycloalkylamino, lkylalkylamino, heterocyclyl, heterocycyloxy, heterocycylamino, halo, haloalkyl, fluoroalkyloxy, aryl, heteroaryloxy, heteroarylamino, arylalkyl, arylalkyloxy, arylalkylamino, heteroarylalkyl, heteroarylalkyloxy, heteroarylalkylamino, hydroxyalkyl, aminoalkyl, and alkylaminoalkyl; and each R6a, R6b, and R6c is a member independently selected from en and alkyl; wherein if R4 is -(CO)OR6a, R6a is alkyl; wherein the polyamine compound comprises at least six primary or secondary amino groups.

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.
[0068] An alkenyl group can be unsubstituted or optionally substituted. When optionally substituted, one or more hydrogen atoms of the alkenyl group (e.g., from 1 to 4, from 1 to 2, or I) may be replaced with a moiety independently selected from fluoro, y, , amino, alkylamino, acylamino, thio, and hio, with the proviso that no hydrogen atom substituent on the carbon-carbon double bond is replaced by a hydroxy, amino, or thio group.
In some aspects, the alkenyl group is unsubstituted or not optionally tuted.
The term “alkyl” as used herein includes an aliphatic hydrocarbon chain that may be straight chain or branched. The chain may contain an indicated number of carbon atoms: For example, C1-C12 indicates that the group may have from 1 to 12 (inclusive) carbon atoms in it.

[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.

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.

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 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, Escherichia, Entembacter, Francisella, Fusobacterium, Flavobacterium, Haemophilus, Helicobacter, Kingella, Klebsiella, Legionella, Listeria, Leptospirae, Moraxella, Morganella, Mycoplasma, Mycobacterium, Neisseria, Pasteurella, Proteus, Prevotella, monas, Pseudomonas, Providencia, Rickettsia, Stenotrophomonas, Staphylococcus, Streptococcus, Streptomyces, Salmonella, Serratia, Shigella, Spirillum, Treponema, Veillonella, Vibrio, 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.

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.

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 published previously. Williams et al., In Vivo Efficacy ofa Silicone - Cationic d Antimicrobial Coating to Prevent Implant-Related Infection, Biomaterials 33, 8641—8656 (2012); Williams et al., Use ofdelrin plastic in a modified CDC biofilm reactor, Res J Microbiol 6, 425-429 (2011); Williams et al, Experimental model ofbiofilm implant-related osteomyelitis to test combination biomaterials using biofilms as initial inocula, J Biomed Mat Res A 100, 1888-1900 (2012); Williams et al., A modified CDC biofilm reactor to produce 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.
Model oil pipeline ination using Alcanivorax ensis. shows an example ofmicrobial contamination in the oil and gas industry. To test the ability and efficacy of the novel synthesized compounds to disperse and kill biofilms that may exist in a variety of settings, a model oil pipeline system was prepared to grow biofilms ofA. borkumensis, a gram-negative organism that metabolizes alkane chains. In cases of oil spills, this organism may be beneficial for bioremediation, but in this instance, it was used to represent bacteria in an oil field or pipeline that may have adverse or ed effects of oil degradation.
B shows a representative bacteria biofilm, such as the biofilm shown in FIG. l4A, d ing to certain standards in the oil and gas industry. The biofilm shown in B was d with a solution comprising 0.25% glutaraldehyde. A similar entative biofilm was treated with a solution comprising 0.5% of a polyamine compound described herein, and is shown in C. shows the results of treating biofilms of Alcam'vorax ensz's grown on the surface of galvanized steel with a solution comprising 0.25% of a polyamine compound ofthe present invention.
Combination ent. Data collected with benzylnorspermidine (CZ-7; PBC-7) at 0.25% mixed with chlorhexidine gluconate at 0.25% has shown significant dispersal of a biofilm ofMRSA that consisted of 1011 cells within one hour.
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.

[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.

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.
Example 8 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.

Data reported in ug/mL and uM concentrations.
EBEC data were collected to determine the efficacy of CZ-52, CZ-58 and traditional antibiotics against high number biofilms ning approximately 109 CFU grown on the surface of a polyetheretherketone (PEEK) membrane. Results are shown 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 MRSA ed to A. baumannz’z’, CZ-58 had greater activity against biofilms ofA. baumanm‘i than against MRSA biofilms in the EBEC assay. The EBEC ofpolymyxin B againstA. baumanm‘z‘ was 1,000); greater than the MIC, whereas the EBEC for CZ-58 was 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.

Example 98 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.

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.
