Definitions
- the present invention is directed, in part, to compounds (e. g. oxacazones) , or pharmaceutically acceptable salts thereof, for treating Clostridium difficile (C. diff. or C. difficile)
- Clostridium difficile Clostridium difficile
- Toxin A is an enterotoxin which stimulates infiltration of neutrophils and release of mediators of inflammation, resulting in fluid secretion, altered membrane permeability and hemorrhagic necrosis.
- C. difficile also produces Toxin B which is a cytotoxin.
- AAD antibiotic-associated diarrhea
- PMC pseudomembranous colitis
- C. difficile-associated diarrhea is a disease characterized by severe and painful diarrhea. C. difficileis responsible for approximately 20% of all cases of antibiotic-associated diarrhea (AAD) and the majority of the cases of antibiotic-associated colitis (AAC) . These diseases are typically caused by toxin producing strains of C. difficile. AAD is a significant problem in hospitals and long-term care facilities and in the community. The rising incidence of C. difficile-associated diarrhea (CDAD) has been attributed to the frequent prescription of broad-spectrum antibiotics to hospitalized patients.
- CDAD pseudomembranous colitis
- Vancomycin is not recommended for first-line treatment of CDAD mainly because it is the only antibiotic active against some serious life-threatening multi-drug resistant bacteria.
- Metronidazole is used for treating CDAD.
- C. difficileresistance may be more than >6% in some locations.
- Fidaxomicin was approved for treatment of CDAD in May, 2011. This compound is described in U. S. Pat. 7,906,489.
- LFF-571 which is a semi-synthetic thiopeptide is currently undergoing clinical trials for the treatment of patients with moderate C. difficile infections.
- LFF-571 is active against a variety of Gram-positive pathogens and has been shown to be more effective than vancomycin in hamsters. (Trzasko et al. , ICAAC, 9/12/2010, Boston, MA. )

Abstract
Compounds, compositions, and methods for treating C. difficile are provided.
Description
The present invention is directed, in part, to compounds (e. g. oxacazones) , or pharmaceutically acceptable salts thereof, for treating Clostridium difficile (C. diff. or C. difficile)
One species of Gram-positive bacteria, Clostridium difficile (C. difficile) , is known to cause a number of serious conditions and diseases. C. difficile produces Toxin A which is an enterotoxin which stimulates infiltration of neutrophils and release of mediators of inflammation, resulting in fluid secretion, altered membrane permeability and hemorrhagic necrosis. C. difficile also produces Toxin B which is a cytotoxin. C. difficile can cause antibiotic-associated diarrhea (AAD) that can lead to pseudomembranous colitis (PMC) , asevere inflammation of the colon. These conditions often arise from the reduction or eradication of the normal gut flora by antibiotics or, less c ommonly, by cancer chemotherapy.
C. difficile-associated diarrhea (CDAD) is a disease characterized by severe and painful diarrhea. C. difficileis responsible for approximately 20% of all cases of antibiotic-associated diarrhea (AAD) and the majority of the cases of antibiotic-associated colitis (AAC) . These diseases are typically caused by toxin producing strains of C. difficile. AAD is a significant problem in hospitals and long-term care facilities and in the community. The rising incidence of C. difficile-associated diarrhea (CDAD) has been attributed to the frequent prescription of broad-spectrum antibiotics to hospitalized patients.
The most serious form of CDAD is pseudomembranous colitis (PMC) , which is manifested histologically by colitis with mucosal plaques, and clinically by severe diarrhea, abdominal cramps, and systemic toxicity. The overall mortality rate from CDAD is low, but is much greater in patients who develop severe colitis or systemic toxicity.
There are currently several therapies for CDAD including vancomycin, metronidazole, and fidaxomicin. Vancomycin is not recommended for first-line treatment of CDAD mainly because it is the only antibiotic active against some serious life-threatening multi-drug resistant bacteria.
Metronidazole is used for treating CDAD. However, C. difficileresistance may be more than >6% in some locations. Fidaxomicin was approved for treatment of CDAD in May, 2011. This compound is described in U. S. Pat. 7,906,489. Additionally, a new compound, LFF-571, which is a semi-synthetic thiopeptide is currently undergoing clinical trials for the treatment of patients with moderate C. difficile infections. LFF-571 is active against a variety of Gram-positive pathogens and has been shown to be more effective than vancomycin in hamsters. (Trzasko et al. , ICAAC, 9/12/2010, Boston, MA. )
However, these compounds have significant side effects, may not be effective for important strains of C. difficile, and are not sufficiently selective for inhibiting C. difficile. Thus, there is a need for enhanced methods for inhibiting C. difficile and for treating C. difficile infection.

Other resolving agents suitable for fractional crystallization methods include, but are not limited to, stereoisomerically pure forms of α-methylbenzylamine (e. g. , Sand R forms, or diastereomerically pure forms) , 2-phenylglycinol, norephedrine, ephedrine, N-methylephedrine, cyclohexylethylamine, 1, 2-diaminocyclohexane, and the like. Resolution of racemic mixtures can also be carried out by elution on a column packed with an optically active resolving agent (e. g. , dinitrobenzoylphenylglycine) . Suitable elution solvent compositions can be determined by one skilled in the art.
Compounds may also include tautomeric forms. Tautomeric forms result from the swapping of a single bond with an adjacent double bond together with the concomitant migration of a proton. Tautomeric forms include prototropic tautomers which are isomeric protonation states having the same empirical formula and total charge. Examples of prototropic tautomers include, but are not limited to, ketone-enol pairs, amide-imidic acid pairs, lactam-lactim pairs, amide-imidic acid pairs, enamine-imine pairs, and annular forms where a proton can occupy two or more positions of a heterocyclic system including, but not limited to, 1H-and 3H-imidazole, 1H-, 2H-and 4H-1, 2, 4-triazole, 1H-and 2H-isoindole, and 1H-and 2H-pyrazole. Tautomeric forms can be in equilibrium or sterically locked into one form by appropriate substitution.
Compounds also include hydrates and solvates, as well as anhydrous and non-solvated forms.
Compounds can also include all isotopes of atoms occurring in the intermediates or final compounds. Isotopes include those atoms having the same atomic number but different mass numbers. For example, isotopes of hydrogen include tritium and deuterium.
In some embodiments, the compounds, or salts thereof, are substantially isolated. Partial separation can include, for example, a composition enriched in the compound of the invention. Substantial separation can include compositions containing at least about 50% , at least about 60% , at least about 70% , at least about 80% , at least about 90% , at least about 95% , at least about 97% , or at least about 99% by weight of the compound of the invention, or salt thereof. Methods for isolating compounds and their salts are routine in the art.
Although the disclosed compounds are suitable, other functional groups can be incorporated into the compound with an expectation of similar results. In particular, thioamides and thioesters are anticipated to have very similar properties. The distance between aromatic rings can impact the geometrical pattern of the compound and this distance can be altered by incorporating aliphatic chains of varying length, which can be optionally substituted or can comprise an amino acid, a dicarboxylic acid or a diamine. The distance between and the relative orientation of monomers within the compounds can also be altered by replacing the amide bond with a surrogate having additional atoms. Thus, replacing a carbonyl group with a dicarbonyl alters the distance between the monomers and the propensity of dicarbonyl unit to adopt an anti arrangement of the two carbonyl moiety and alter the periodicity of the compound. Pyromellitic anhydride represents still another alternative to simple amide linkages which can alter the conformation and physical properties of the compound. Modern methods of solid phase organic chemistry (E. Atherton and R. C. Sheppard, Solid Phase Peptide Synthesis A Practical Approach IRL Press Oxford 1989) now allow the synthesis of homodisperse compounds with molecular weights approaching 5,000 Daltons. Other substitution patterns are equally effective.
The compounds also include derivatives referred to as prodrugs.
Compounds containing an amine function can also form N-oxides. A reference herein to a compound that contains an amine function also includes the N-oxide. Where a compound contains several amine functions, one or more than one nitrogen atom can be oxidized to form an N-oxide. Examples of N-oxides include N-oxides of a tertiary amine or a nitrogen atom of a
nitrogen-containing heterocycle. N-Oxides can be formed by treatment of the corresponding amine with an oxidizing agent such as hydrogen peroxide or a per-acid (e. g. , aperoxycarboxylic acid) (see, Advanced Organic Chemistry, by Jerry March, 4th Edition, Wiley Interscience) .

The amount of compound to be administered is that amount which is therapeutically effective. The dosage to be administered will depend on the characteristics of the subject being treated, e. g. , the particular animal treated, age, weight, health, types of concurrent treatment, if any, and frequency of treatments, and can be easily determined by one of skill in the art (e. g. , by the clinician) . The standard dosing for protamine can be used and adjusted (i. e. , increased or decreased) depending upon the factors described above. The selection of the specific dose
regimen can be selected or adjusted or titrated by the clinician according to methods known to the clinician to obtain the desired clinical response.
The amount of a compound described herein that will be effective in the treatment and/or prevention of a particular disease, condition, or disorder will depend on the nature and extent of the disease, condition, or disorder, and can be determined by standard clinical techniques. In addition, in vitro or in vivo assays may optionally be employed to help identify optimal dosage ranges. The precise dose to be employed in the compositions will also depend on the route of administration, and the seriousness of the disorder, and should be decided according to the judgment of the practitioner and each patient’ scircumstances. However, a suitable dosage range for oral administration is, generally, from about 0.001 milligram to about 200 milligrams per kilogram body weight, from about 0.01 milligram to about 100 milligrams per kilogram body weight, from about 0.01 milligram to about 70 milligrams per kilogram body weight, from about 0.1 milligram to about 50 milligrams per kilogram body weight, from 0.5 milligram to about 20 milligrams per kilogram body weight, or from about 1 milligram to about 10 milligrams per kilogram body weight.

Examples
Example 1: Methods of Making Compounds. All oxygen and/or moisture sensitive reactions were carried out under N2 atmosphere in glassware that had flame-dried under vacuum (0.5 mmHg) and purged with N2 prior to use. All reagents and solvents were purchased from commercial vendors and used as received, or synthesized according to the footnoted references. NMR spectra were recorded on a Bruker 400 (400 MHz 1H, 75 MHz 13C) or Varian (400 MHz 1H, 75 MHz 13C) spectrometer. Proton and carbon chemical shifts are reported in ppm (δ)
referenced to the NMR solvent. Data are reported as follows: chemical shifts, multiplicity (br=broad, s=singlet, t=triplet, q=quartet, m=multiplet; coupling constant (s) in Hz) . Unless otherwise indicated NMR data were collected at 25 ℃. Flash chromatography was performed using 100-200 mesh Silica Gel. Liquid Chromotography /Mass Spectrometry (LCMS) was performed on Agilent1200HPLC and 6110MS. Analytical thin layer chromatography (TLC) was performed on 0.2 mm silica gel plates. Visualization was accomplished with UV light and aqueous potassium permanganate (KMnO4) stain followed by heating.
(2S, 3S) -4- ( (tert-butoxycarbonyl) (methyl) amino) -3-hydroxy-2-methylbutanoic acid, S2. A jacketed 5-L, 3-neck round bottom flask was fitted with a magnetic stirrer and internal temperature probe. Under a positive flow of N2, the reactor was charged with (4S) -4-benzyl-3-propanoyl-oxazolidin-2-one (78.00 g, 334.39 mmol) followed by CH2Cl2 (835 mL) . The colorless solution was cooled to an internal temperature of -10 ℃ and sparged with N2 for 30 min. Dibutylboron triflate (402 mL, 401.26 mmol, 1 M in toluene) was added by dropwise addition, maintaining an internal temperature below -0.5 ℃. To the resulting yellow-green colored solution was added TEA (50.75 g, 501.58 mmol) dropwise while maintaining the internal temperature below -0.5 ℃ and the resulting bright yellow enolate solution was stirred at -5 ℃ for 90 min. Tert-butyl N-methyl-N- (2-oxoethyl) carbamate (75.29 g, 434.70 mmol) was added dropwise, keeping the internal temperature below -0.5 ℃. Upon complete addition, the light yellow solution was stirred at -5 ℃ for 90 min. The solution was cooled to -10 ℃ and quenched by the slow addition of MeOH (420 mL) followed by a solution of THF: H2O2 (1.2L, 2: 1) that changed the yellow homogenous solution to a biphasic milky-white suspension. The initial rapid exotherm induced by the peroxide addition can be minimized by slow addition until no further exotherm is observed. The reaction was stirred at -10 ℃ for 90 min at which time both layers became homogeneous. LiOH (70.2 g, 1.67 mol) was added to the biphasic mixture and the mixture was allowed to warm to r. t. and stirred for 12 h.
Excess peroxides were reduced by the careful addition of solid Na2SO3, organic solvents were removed in vacuo, and the slurry was dissolved in CH2Cl2. The organic layer was washed with
aq. NaOH (1.0 M, 1 L) and brine (100 mL) . The aqueous layer was back extracted with CH2Cl2 (2x100 mL) to remove the oxazolidinone. The combined aqueous layers were cooled to 0 ℃, agitated with a magnetic stir bar and then carefully acidified with concentrated HCl (12 M) until pH=4 as indicated by pH strip. The aqueous layer was extracted with ethyl acetate (3x600 mL) . The combined organics were dried over MgSO4 and concentrated to provide (2S, 3S) -4- [tert-butoxycarbonyl (methyl) amino] -3-hydroxy-2-methyl-butanoic acid S2 (80.00 g, 323.51 mmol, 97% yield) as a yellow oil.

The reaction mixture was cooled to -78 ℃ and tert-butyldimethylsilyl trifluoromethanesulfonate (TBSOTf) (325.17 g, 1.23 mol) was added dropwise over 20 min. The reaction mixture was stirred at -78 ℃ for 1 h, quenched with aqueous sat. NaHCO3, the layers were separated, and the aqueous layer was extracted with CH2Cl2. The combined organic extracts were washed with sat. NH4Cl and brine, dried (Na2SO4) , filtered and the solvent evaporated. The residue was dissolved in MeOH (800 mL) and THF (800 mL) and cooled to 0 ℃. An aqueous solution of K2CO3 (98.09 g, 709.70 mmol, 210 mL) was added and the mixture was stirred at 0 ℃ for 1 h. The reaction mixture was concentrated to remove volatiles and the remaining aqueous layer was extracted with EtOAc. The organic layer was washed with 1 N HCl, then dried over Na2SO4, filtered and concentrated in vacuo to yield the crude product as a clear oil which was coevaporated with toluene to remove excess TBSOH and dried to provide (2S, 3S) -4- [tert-

The resulting mixture was cooled in an ice bath before (2S) -1- [ (4-methoxyphenyl) methoxy] propan-2-amine (71.29 g, 365.10 mmol, 1.20 equiv) was added as a solution in CH2Cl2 (0.5L) by addition funnel. The rate of addition was controlled so as to maintain an internal temperature between 3-5 ℃. When addition was complete, the mixture was warmed to ambient temperature and allowed to stir for 15 h. The reaction was quenched with water, and extracted with CH2Cl2. The combined organic extracts were dried over MgSO4, filtered and concentrated. The yellow oil was taken up in Et2O and the phosphoramide byproducts were removed via filtration. The solvent was removed in vacuo and the crude product was isolated.

Example 2: Compounds inhibit Clostridium difficile.
Vancomycin was purchased from Sigma (Sigma 94747-5G) . Bacteria tested were Clostridium difficile ATCC 700057, ATCC BAA-1870, ATCC BAA-1382 and ATCC 43255. All bacterial strains were purchased from American Type Culture Collection (ATCC) . The bacteria were cultured according to the manual from ATCC and frozen in 25% (final concentration) glycerol at -80 ℃.
Broth Microdilution based Minimum Inhibition Concentration (MIC) determination: On the day of testing, the compounds were dissolved in pure DMSO (Sigma 276855-2L) to 3.2mg/ml as stock. In a v-bottom 96-well plate (Axygen-wipp02280) , 30 μl DMSO was added into well 1 to well 12 by manual pipetting. Into well 1, 30 μl of compound DMSO stock (3.2 mg/ml) was added and mixed by pipetting. Two fold serial dilutions were performed by transferring and mixing 30 μl of solution from well 1 to well 2, then well 2 to well 3 and so forth until well 11. The well 12 was loaded with 30 μl DMSO without compounds. This was drug ‘mother plate’ . From well 1 to well 12, the drug concentrations in the mother plate were 1.6, 0.8, 0.4, 0.2, 0.1, 0.05, 0.025, 0.0125, 0.00625, 0.003125, 0.0015625 and 0 mg/ml in DMSO. A multi-pipette was used to perform the serial dilutions.
For preparing u-bottom 96-well ‘daughter plates’ (Costar 3788) , 98 μl of Brain Heart Infusion (BHI) (BD 237500) broth was added into each well of a daughter plate. An aliquot of 2 μl solution from mother plate was then replicating transferred into the daughter plate using a multi-pipette. The daughter plate was then transferred into an YQX-II anaerobic workstation (Shanghai Yuejin Medical instruments Co. , Ltd. ) to equilibrate in anaerobic atmosphere for 3 hours before adding the bacterial suspension.
The preparation of bacterial inoculum was done in YQX-II anaerobic workstation. Two days prior to the day of MIC test, bacterial strains were streaked out from-80 ℃ glycerol stock onto Brain Heart Infusion Agar (BHA) (BD-211065) plates and incubated at 37 ℃ for 48 h. The single colonies were picked by using an inoculation loop (Greiner-731175) and suspended into 5 ml sterile saline. The turbidity of the suspension was adjusted to 0.12 (Siemens MicroScan turbidity meter) , equal to ~4×107 cfu/ml. The bacterial suspension was then diluted 40× in BHI. This was used for inoculation of daughter plates.
An aliquot of 100 μl of the bacterial suspension was inoculated into each well of the daughter plates using a multi-pipette. Each well contains ~1.0×105 cfu bacteria, 1% DMSO and serially diluted compounds at 16, 8, 4, 2, 1, 0.5, 0.25, 0.125, 0.0625, 0.03125, 0.015625 and 0 μg/ml from well 1 to well 12 respectively, in 200 μl BHI.
The plates were incubated at 37 ℃ in YQX-II anaerobic workstation for 48 hours.
The MIC values were determined by following the standards of CLSI methods M11-A7, broth microdilution method. Briefly, MIC is the lowest compound concentration that completely or markedly inhibits the growth of bacteria in the testing medium.
Figures 1-8 illustrate the results obtained for the various compounds against Clostridium difficile. The compounds were found to be specifically active against Clostridium difficile, which can be seen through the lack of significant activity against Staphylococcus aureus.
