All publications, patents, and patent applications mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication, patent, or patent application was specifically and individually indicated to be incorporated by reference.
As used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise.
The term “about” as used herein, when referring to a numerical value or range, allows for a degree of variability in the value or range, for example, within 10%, or within 5% of a stated value or of a stated limit of a range.
All percent compositions are given as weight-percentages, unless otherwise stated.
All average molecular weights of polymers are weight-average molecular weights, unless otherwise specified.
As used herein, “individual” (as in the subject of the treatment) means both mammals and non-mammals. Mammals include, for example, humans; non-human primates, e.g. apes and monkeys; and non-primates, e.g. dogs, cats, cattle, horses, sheep, and goats. Non-mammals include, for example, fish and birds.
The term “disease” or “disorder” or “malcondition” are used interchangeably, and are used to refer to diseases or conditions wherein a bacterial SPase plays a role in the biochemical mechanisms involved in the disease or malcondition such that a therapeutically beneficial effect can be achieved by acting on the enzyme. “Acting on” SPase can include binding to SPase and/or inhibiting the bioactivity of an SPase.
The expression “effective amount”, when used to describe therapy to an individual suffering from a disorder, refers to the amount of a compound described herein that is effective to inhibit or otherwise act on SPase in the individual's tissues wherein SPase involved in the disorder is active, wherein such inhibition or other action occurs to an extent sufficient to produce a beneficial therapeutic effect.
“Substantially” as the term is used herein means completely or almost completely; for example, a composition that is “substantially free” of a component either has none of the component or contains such a trace amount that any relevant functional property of the composition is unaffected by the presence of the trace amount, or a compound is “substantially pure” is there are only negligible traces of impurities present.
“Treating” or “treatment” within the meaning herein refers to an alleviation of symptoms associated with a disorder or disease, or inhibition of further progression or worsening of those symptoms, or prevention or prophylaxis of the disease or disorder, or curing the disease or disorder. Similarly, as used herein, an “effective amount” or a “therapeutically effective amount” of a compound refers to an amount of the compound that alleviates, in whole or in part, symptoms associated with the disorder or condition, or halts or slows further progression or worsening of those symptoms, or prevents or provides prophylaxis for the disorder or condition. In particular, a “therapeutically effective amount” refers to an amount effective, at dosages and for periods of time necessary, to achieve the desired therapeutic result. A therapeutically effective amount is also one in which any toxic or detrimental effects of compounds described herein are outweighed by the therapeutically beneficial effects.
By “chemically feasible” is meant a bonding arrangement or a compound where the generally understood rules of organic structure are not violated; for example a structure within a definition of a claim that would contain in certain situations a pentavalent carbon atom that would not exist in nature would be understood to not be within the claim. The structures disclosed herein, in all of their embodiments are intended to include only “chemically feasible” structures, and any recited structures that are not chemically feasible, for example in a structure shown with variable atoms or groups, are not intended to be disclosed or claimed herein.
When a substituent is specified to be an atom or atoms of specified identity, “or a bond”, a configuration is referred to when the substituent is “a bond” that the groups that are immediately adjacent to the specified substituent are directly connected to each other in a chemically feasible bonding configuration.
All chiral, diastereomeric, racemic forms of a structure are intended, unless a particular stereochemistry or isomeric form is specifically indicated. Compounds described herein can include enriched or resolved optical isomers at any or all asymmetric atoms as are apparent from the depictions, at any degree of enrichment. Both racemic and diastereomeric mixtures, as well as the individual optical isomers can be isolated or synthesized so as to be substantially free of their enantiomeric or diastereomeric partners, and these are all within the scope of the invention.
The inclusion of an isotopic form of one or more atoms in a molecule that is different from the naturally occurring isotopic distribution of the atom in nature is referred to as an “isotopically labeled form” of the molecule. All isotopic forms of atoms are included as options in the composition of any molecule, unless a specific isotopic form of an atom is indicated. For example, any hydrogen atom or set thereof in a molecule can be any of the isotopic forms of hydrogen, i.e., protium (1H), deuterium (2H), or tritium (3H) in any combination. Similarly, any carbon atom or set thereof in a molecule can be any of the isotopic form of carbons, such as 11C, 12C, 13C, or 14C, or any nitrogen atom or set thereof in a molecule can be any of the isotopic forms of nitrogen, such as 13N, 14N, or 15N. A molecule can include any combination of isotopic forms in the component atoms making up the molecule, the isotopic form of every atom forming the molecule being independently selected. In a multi-molecular sample of a compound, not every individual molecule necessarily has the same isotopic composition. For example, a sample of a compound can include molecules containing various different isotopic compositions, such as in a tritium or 14C radiolabeled sample where only some fraction of the set of molecules making up the macroscopic sample contains a radioactive atom. It is also understood that many elements that are not artificially isotopically enriched themselves are mixtures of naturally occurring isotopic forms, such as 14N and 15N, 32S and 34S, and so forth. A molecule as recited herein is defined as including isotopic forms of all its constituent elements at each position in the molecule. As is well known in the art, isotopically labeled compounds can be prepared by the usual methods of chemical synthesis, except substituting an isotopically labeled precursor molecule. The isotopes, radiolabeled or stable, can be obtained by any method known in the art, such as generation by neutron absorption of a precursor nuclide in a nuclear reactor, by cyclotron reactions, or by isotopic separation such as by mass spectrometry. The isotopic forms are incorporated into precursors as required for use in any particular synthetic route. For example, 14C and 3H can be prepared using neutrons generated in a nuclear reactor. Following nuclear transformation, 14C and 3H are incorporated into precursor molecules, followed by further elaboration as needed.

In general, “substituted” refers to an organic group as defined herein in which one or more bonds to a hydrogen atom contained therein are replaced by one or more bonds to a non-hydrogen atom such as, but not limited to, a halogen (i.e., F, Cl, Br, and I); an oxygen atom in groups such as hydroxyl groups, alkoxy groups, aryloxy groups, aralkyloxy groups, oxo(carbonyl) groups, carboxyl groups including carboxylic acids, carboxylates, and carboxylate esters; a sulfur atom in groups such as thiol groups, alkyl and aryl sulfide groups, sulfoxide groups, sulfone groups, sulfonyl groups, and sulfonamide groups; a nitrogen atom in groups such as amines, hydroxylamines, nitriles, nitro groups, N-oxides, hydrazides, azides, and enamines; and other heteroatoms in various other groups. Non-limiting examples of substituents that can be bonded to a substituted carbon (or other) atom include F, Cl, Br, T, OR′, OC(O)N(R′)2, CN, NO, NO2, ONO2, azido, CF3, OCF3, R′, O (oxo), S (thiono), C(O), S(O), methylenedioxy, ethylenedioxy, N(R′)2, SR′, SOR′, SO2R′, SO2N(R′)2, SO3R′, C(O)R′, C(O)C(O)R′, C(O)CH2C(O)R′, C(S)R′, C(O)OR′, OC(O)R′, C(O)N(R′)2, OC(O)N(R′)2, C(S)N(R′)2, (CH2)0-2N(R′)C(O)R′, (CH2)0-2N(R′)N(R′)2, N(R′)N(R′)C(O)R′, N(R′)N(R′)C(O)OR′, N(R′)N(R′)CON(R′)2, N(R′)SO2R′, N(R′)SO2N(R′)2, N(R′)C(O)OR′, N(R′)C(O)R′, N(R′)C(S)R′, N(R′)C(O)N(R′)2, N(R′)C(S)N(R′)2, N(COR′)COR′, N(OR′)R′, C(═NH)N(R′)2, C(O)N(OR′)R′, or C(═NOR′)R′ wherein R′ can be hydrogen or a carbon-based moiety, and wherein the carbon-based moiety can itself be further substituted.
When a substituent is monovalent, such as, for example, F or C1, it is bonded to the atom it is substituting by a single bond. When a substituent is more than monovalent, such as O, which is divalent, it can be bonded to the atom it is substituting by more than one bond, i.e., a divalent substituent is bonded by a double bond; for example, a C substituted with O forms a carbonyl group, C═O, which can also be written as “CO”, “C(O)”, or “C(═O)”, wherein the C and the O are double bonded. When a carbon atom is substituted with a double-bonded oxygen (═O) group, the oxygen substituent is termed an “oxo” group. When a divalent substituent such as NR is double-bonded to a carbon atom, the resulting C(═NR) group is termed an “imino” group. When a divalent substituent such as S is double-bonded to a carbon atom, the results C(═S) group is termed a “thiocarbonyl” group.
Alternatively, a divalent substituent such as O, S, C(O), S(O), or S(O)2 can be connected by two single bonds to two different carbon atoms. For example, O, a divalent substituent, can be bonded to each of two adjacent carbon atoms to provide an epoxide group, or the O can form a bridging ether group, termed an “oxy” group, between adjacent or non-adjacent carbon atoms, for example bridging the 1,4-carbons of a cyclohexyl group to form a [2.2.1]-oxabicyclo system. Further, any substituent can be bonded to a carbon or other atom by a linker, such as (CH2)n or (CR′2)n wherein n is 1, 2, 3, or more, and each R′ is independently selected.
C(O) and S(O)2 groups can be bound to one or two heteroatoms, such as nitrogen, rather than to a carbon atom. For example, when a C(O) group is bound to one carbon and one nitrogen atom, the resulting group is called an “amide” or “carboxamide.” When a C(O) group is bound to two nitrogen atoms, the functional group is termed a urea. When a S(O)2 group is bound to one carbon and one nitrogen atom, the resulting unit is termed a “sulfonamide.” When a S(O)2 group is bound to two nitrogen atoms, the resulting unit is termed a “sulfamate.”
Substituted alkyl, alkenyl, alkynyl, cycloalkyl, and cycloalkenyl groups as well as other substituted groups also include groups in which one or more bonds to a hydrogen atom are replaced by one or more bonds, including double or triple bonds, to a carbon atom, or to a heteroatom such as, but not limited to, oxygen in carbonyl (oxo), carboxyl, ester, amide, imide, urethane, and urea groups; and nitrogen in imines, hydroxyimines, oximes, hydrazones, amidines, guanidines, and nitriles.
Substituted ring groups such as substituted cycloalkyl, aryl, heterocyclyl and heteroaryl groups also include rings and fused ring systems in which a bond to a hydrogen atom is replaced with a bond to a carbon atom. Therefore, substituted cycloalkyl, aryl, heterocyclyl and heteroaryl groups can also be substituted with alkyl, alkenyl, and alkynyl groups as defined herein.
By a “ring system” as the term is used herein is meant a moiety comprising one, two, three or more rings, which can be substituted with non-ring groups or with other ring systems, or both, which can be fully saturated, partially unsaturated, fully unsaturated, or aromatic, and when the ring system includes more than a single ring, the rings can be fused, bridging, or spirocyclic. By “spirocyclic” is meant the class of structures wherein two rings are fused at a single tetrahedral carbon atom, as is well known in the art.
As to any of the groups described herein, which contain one or more substituents, it is understood, of course, that such groups do not contain any substitution or substitution patterns which are sterically impractical and/or synthetically non-feasible. In addition, the compounds of this disclosed subject matter include all stereochemical isomers arising from the substitution of these compounds.
Selected substituents within the compounds described herein are present to a recursive degree. In this context, “recursive substituent” means that a substituent may recite another instance of itself or of another substituent that itself recites the first substituent. Because of the recursive nature of such substituents, theoretically, a large number may be present in any given claim. One of ordinary skill in the art of medicinal chemistry and organic chemistry understands that the total number of such substituents is reasonably limited by the desired properties of the compound intended. Such properties include, by of example and not limitation, physical properties such as molecular weight, solubility or log P, application properties such as activity against the intended target, and practical properties such as ease of synthesis.
Recursive substituents are an intended aspect of the disclosed subject matter. One of ordinary skill in the art of medicinal and organic chemistry understands the versatility of such substituents. To the degree that recursive substituents are present in a claim of the disclosed subject matter, the total number should be determined as set forth above.

A “pharmaceutically acceptable” or “pharmacologically acceptable” salt is a salt formed from an ion that has been approved for human consumption and is generally non-toxic, such as a chloride salt or a sodium salt. A “zwitterion” is an internal salt such as can be formed in a molecule that has at least two ionizable groups, one forming an anion and the other a cation, which serve to balance each other. For example, amino acids such as glycine can exist in a zwitterionic form. A “zwitterion” is a salt within the meaning herein. The compounds described herein may take the form of salts. The term “salts” embraces addition salts of free acids or free bases which are compounds described herein. Salts can be “pharmaceutically-acceptable salts.” The term “pharmaceutically-acceptable salt” refers to salts which possess toxicity profiles within a range that affords utility in pharmaceutical applications. Pharmaceutically unacceptable salts may nonetheless possess properties such as high crystallinity, which have utility in the practice of the present disclosure, such as for example utility in process of synthesis, purification or formulation of compounds of the present disclosure.
Suitable pharmaceutically-acceptable acid addition salts may be prepared from an inorganic acid or from an organic acid. Examples of inorganic acids include hydrochloric, hydrobromic, hydriodic, nitric, carbonic, sulfuric, and phosphoric acids. Appropriate organic acids may be selected from aliphatic, cycloaliphatic, aromatic, araliphatic, heterocyclic, carboxylic and sulfonic classes of organic acids, examples of which include formic, acetic, propionic, succinic, glycolic, gluconic, lactic, malic, tartaric, citric, ascorbic, glucuronic, maleic, fumaric, pyruvic, aspartic, glutamic, benzoic, anthranilic, 4-hydroxybenzoic, phenylacetic, mandelic, embonic (pamoic), methanesulfonic, ethanesulfonic, benzenesulfonic, pantothenic, trifluoromethanesulfonic, 2-hydroxyethanesulfonic, p-toluenesulfonic, sulfanilic, cyclohexylaminosulfonic, stearic, alginic, β-hydroxybutyric, salicylic, galactaric and galacturonic acid.

Pharmaceutically acceptable base addition salts also include organic salts made from basic amines such as, for example, N,N′-dibenzylethylenediamine, chloroprocaine, choline, diethanolamine, ethylenediamine, meglumine (N-methylglucamine) and procaine. Examples of pharmaceutically unacceptable base addition salts include lithium salts and cyanate salts. Although pharmaceutically unacceptable salts are not generally useful as medicaments, such salts may be useful, for example as intermediates in the synthesis of Formula (I), (I′), (Ia), (Ib), (Ic), (Id), (II), (II′), (IIa), (IIb), (IIc), (IId), or (IIe) compounds, for example in their purification by recrystallization. All of these salts may be prepared by conventional means from the corresponding compound according to Formula (I), (I′), (Ia), (Ib), (Ic), (Id), (II), (II′), (IIa), (IIb), (IIc), (IId), or (IIe) by reacting, for example, the appropriate acid or base with the compound according to Formula (I), (I′), (Ia), (Ib), (Ic), (Id), (II), (II′), (IIa), (IIb), (IIc), (IId), or (IIe). The term “pharmaceutically acceptable salts” refers to nontoxic inorganic or organic acid and/or base addition salts, see, for example, Lit et al., Salt Selection for Basic Drugs (1986), Int J. Pharm., 33, 201-217, incorporated by reference herein.
A “hydrate” is a compound that exists in a composition with water molecules. The composition can include water in stoichiometic quantities, such as a monohydrate or a dihydrate, or can include water in random amounts. As the term is used herein a “hydrate” refers to a solid form, i.e., a compound in water solution, while it may be hydrated, is not a hydrate as the term is used herein.
A “solvate” is a similar composition except that a solvent other that water replaces the water. For example, methanol or ethanol can form an “alcoholate”, which can again be stoichiometic or non-stoichiometric. As the term is used herein a “solvate” refers to a solid form, i.e., a compound in solution in a solvent, while it may be solvated, is not a solvate as the term is used herein.
A “prodrug” as is well known in the art is a substance that can be administered to a patient where the substance is converted in vivo by the action of biochemicals within the patients body, such as enzymes, to the active pharmaceutical ingredient. Examples of prodrugs include esters of carboxylic acid groups, which can be hydrolyzed by endogenous esterases as are found in the bloodstream of humans and other mammals. Further examples examples of prodrugs include boronate esters which can be hydrolyzed under physiological conditions to afford the corresponding boronic acid. Conventional procedures for the selection and preparation of suitable prodrug derivatives are described, for example, in “Design of Prodrugs”, ed. H. Bundgaard, Elsevier, 1985.
In addition, where features or aspects of the present disclosure are described in terms of Markush groups, those skilled in the art will recognize that the presently described compounds is also thereby described in terms of any individual member or subgroup of members of the Markush group. For example, if X is described as selected from the group consisting of bromine, chlorine, and iodine, claims for X being bromine and claims for X being bromine and chlorine are fully described. Moreover, where features or aspects of the present disclosure are described in terms of Markush groups, those skilled in the art will recognize that the present disclosure is also thereby described in terms of any combination of individual members or subgroups of members of Markush groups. Thus, for example, if X is described as selected from the group consisting of bromine, chlorine, and iodine, and Y is described as selected from the group consisting of methyl, ethyl, and propyl, claims for X being bromine and Y being methyl are fully described.
If a value of a variable that is necessarily an integer, e.g., the number of carbon atoms in an alkyl group or the number of substituents on a ring, is described as a range, e.g., 0-4, what is meant is that the value can be any integer between 0 and 4 inclusive, i.e., 0, 1, 2, 3, or 4.
In various embodiments, the compound or set of compounds, such as are used in the inventive methods, can be any one of any of the combinations and/or sub-combinations of the above-listed embodiments.
In various embodiments, a compound as shown in any of the Examples, or among the exemplary compounds, is provided. Provisos may apply to any of the disclosed categories or embodiments wherein any one or more of the other above disclosed embodiments or species may be excluded from such categories or embodiments.
The present disclosure further embraces isolated compounds according to Formula (I), (I′), (Ia), (Ib), (Ic), (Id), (TI), (II′), (IIa), (Ib), (IIc), (IId), or (IIe). The expression “isolated compound” refers to a preparation of a compound of Formula (I), (I′), (Ia), (Ib), (Ic), (Id), (II), (II′), (IIa), (IIb), (IIc), (IId), or (IIe), or a mixture of compounds according to Formula (I), (I′), (Ia), (Ib), (Ic), (Id), (TI), (II′), (IIa), (IIb), (IIc), (IId), or (IIe), wherein the isolated compound has been separated from the reagents used, and/or byproducts formed, in the synthesis of the compound or compounds. “Isolated” does not mean that the preparation is technically pure (homogeneous), but it is sufficiently pure to compound in a form in which it can be used therapeutically. Preferably an “isolated compound” refers to a preparation of a compound of Formula (I), (I′), (Ia), (Ib), (Ic), (Id), (II), (II′), (IIa), (Ib), (IIc), (IId), or (IIe) or a mixture of compounds according to Formula (I), (I′), (Ia), (Ib), (Ic), (Id), (II), (II′), (IIa), (IIb), (IIc), (IId), or (IIc), which contains the named compound or mixture of compounds according to Formula (I), (I′), (Ia), (Ib), (Ic), (Id), (II), (II′), (IIa), (IIb), (IIc), (IId), or (IIe) in an amount of at least 10 percent by weight of the total weight. Preferably the preparation contains the named compound or mixture of compounds in an amount of at least 50 percent by weight of the total weight; more preferably at least 80 percent by weight of the total weight; and most preferably at least 90 percent, at least 95 percent or at least 98 percent by weight of the total weight of the preparation.
The compounds described herein and intermediates may be isolated from their reaction mixtures and purified by standard techniques such as filtration, liquid-liquid extraction, solid phase extraction, distillation, recrystallization or chromatography, including flash column chromatography, or HPLC.
Within the present disclosure it is to be understood that a compound of Formula (I), (I′), (Ia), (Ib), (Ic), (Id), (II), (II′), (IIa), (IIb), (IIc), (IId), or (IIe) or a salt thereof may exhibit the phenomenon of tautomerism whereby two chemical compounds that are capable of facile interconversion by exchanging a hydrogen atom between two atoms, to either of which it forms a covalent bond. Since the tautomeric compounds exist in mobile equilibrium with each other they may be regarded as different isomeric forms of the same compound. It is to be understood that the formulae drawings within this specification can represent only one of the possible tautomeric forms. However, it is also to be understood that the present disclosure encompasses any tautomeric form, and is not to be limited merely to any one tautomeric form utilized within the formulae drawings. The formulae drawings within this specification can represent only one of the possible tautomeric forms and it is to be understood that the specification encompasses all possible tautomeric forms of the compounds drawn not just those forms which it has been convenient to show graphically herein. For example, tautomerism may be exhibited by a pyrazolyl group bonded as indicated by the wavy line. While both substituents would be termed a 4-pyrazolyl group, it is evident that a different nitrogen atom bears the hydrogen atom in each structure.
Such tautomerism can also occur with substituted pyrazoles such as 3-methyl, 5-methyl, or 3,5-dimethylpyrazoles, and the like. Another example of tautomerism is amido-imido (lactam-lactim when cyclic) tautomerism, such as is seen in heterocyclic compounds bearing a ring oxygen atom adjacent to a ring nitrogen atom. For example, the equilibrium:
is an example of tautomerism. Accordingly, a structure depicted herein as one tautomer is intended to also include the other tautomer.
It will be understood that when compounds of the present disclosure contain one or more chiral centers, the compounds may exist in, and may be isolated as pure enantiomeric or diastereomeric forms or as racemic mixtures. The present disclosure therefore includes any possible enantiomers, diastereomers, racemates or mixtures thereof of the compounds described herein.
The isomers resulting from the presence of a chiral center comprise a pair of non-superimposable isomers that are called “enantiomers.” Single enantiomers of a pure compound are optically active, i.e., they are capable of rotating the plane of plane polarized light. Single enantiomers are designated according to the Cahn-Ingold-Prelog system. The priority of substituents is ranked based on atomic weights, a higher atomic weight, as determined by the systematic procedure, having a higher priority ranking. Once the priority ranking of the four groups is determined, the molecule is oriented so that the lowest ranking group is pointed away from the viewer. Then, if the descending rank order of the other groups proceeds clockwise, the molecule is designated (R) and if the descending rank of the other groups proceeds counterclockwise, the molecule is designated (S). In the example below, the Cahn-Ingold-Prelog ranking is A>B>C>D. The lowest ranking atom, D is oriented away from the viewer.
The present disclosure is meant to encompass diastereomers as well as their racemic and resolved, diastereomerically and enantiomerically pure forms and salts thereof. Diastereomeric pairs may be resolved by known separation techniques including normal and reverse phase chromatography, and crystallization.
“Isolated optical isomer” means a compound which has been substantially purified from the corresponding optical isomer(s) of the same formula. Preferably, the isolated isomer is at least about 80%, more preferably at least 90% pure, even more preferably at least 98% pure, most preferably at least about 99% pure, by weight.
Isolated optical isomers may be purified from racemic mixtures by well-known chiral separation techniques. According to one such method, a racemic mixture of a compound described herein, or a chiral intermediate thereof, is separated into 99% wt. % pure optical isomers by HPLC using a suitable chiral column, such as a member of the series of DAICEL® CHIRALPAK® family of columns (Daicel Chemical Industries, Ltd., Tokyo, Japan). The column is operated according to the manufacturer's instructions.
It is understood that due to chemical properties (i.e., resonance lending some double bond character to the C—N bond) of restricted rotation about the amide bond linkage (as illustrated below) it is possible to observe separate rotamer species and even, under some circumstances, to isolate such species (see below). It is further understood that certain structural elements, including steric bulk or substituents on the amide nitrogen, may enhance the stability of a rotamer to the extent that a compound may be isolated as, and exist indefinitely, as a single stable rotamer. The present disclosure therefore includes any possible stable rotamers of formula (I) which are biologically active in the treatment of cancer or other proliferative disease states.
In some embodiments, the compounds described herein have a particular spatial arrangement of substituents on the aromatic rings, which is related to the structure activity relationship demonstrated by the compound class. Often such substitution arrangement is denoted by a numbering system; however, numbering systems are often not consistent between different ring systems. In six-membered aromatic systems, the spatial arrangements are specified by the common nomenclature “para” for 1,4-substitution, “meta” for 1,3-substitution and “ortho” for 1,2-substitution as shown below.
In various embodiments, the compound or set of compounds, such as are among the inventive compounds or are used in the inventive methods, can be any one of any of the combinations and/or sub-combinations of the above-listed embodiments.

Methicillin-Resistant Staphylococcus aureus
Staphylococcus aureus (S. aureus), a spherical bacterium, is the most common cause of staph infections. S. aureus has been known to cause a range of illnesses from minor skin infections, such as pimples, impetigo, boils, cellulitis folliculitis, furuncles, carbuncles, scalded skin syndrome, abscesses, to life-threatening diseases such as pneumonia, meningitis, osteomyelitis endocarditis, toxic shock syndrome, and septicemia. Further, S. aureus is one of the most common causes of nosocomial infections, often causing postsurgical wound infections.
Methicillin was introduced in the late 1950s to treat infections caused by penicillin-resistant S. aureus. It has been reported previously that S. aureus isolates had acquired resistance to methicillin (methicillin-resistant S. aureus, MRSA). The methicillin resistance gene (mecA) encodes a methicillin-resistant penicillin-binding protein that is not present in susceptible strains. mecA is carried on a mobile genetic element, the staphylococcal cassette chromosome mec (SCCmec), of which four forms have been described that differ in size and genetic composition. The methicillin-resistant penicillin-binding protein allows for resistance to β-lactam antibiotics and obviates their clinical use during MRSA infections.

Vancomycin-Intermediate and Vancomycin-Resistant Staphylococcus aureus
Vancomycin-intermediate Staphylococcus aureus and vancomycin-resistant Staphylococcus aureus are specific types of antimicrobial-resistant Staph bacteria that are refractory to vancomycin treatment. S. aureus isolates for which vancomycin MICs are 4-8 g/mL are classified as vancomycin-intermediate and isolates for which vancomycin MICs are ≥16 μg/mL are classified as vancomycin-resistant (Clinical and Laboratory Standards Institute/NCCLS. Performance Standards for Antimicrobial Susceptibility Testing. Sixteenth informational supplement. M100-S16. Wayne, Pa.: CLSI, 2006).
As used herein, the term “minimum inhibitory concentration” (MIC) refers to the lowest concentration of an antibiotic that is needed to inhibit growth of a bacterial isolate in vitro. A common method for determining the MIC of an antibiotic is to prepare several tubes containing serial dilutions of the antibiotic, that are then inoculated with the bacterial isolate of interest. The MIC of an antibiotic is determined from the tube with the lowest concentration that shows no turbidity (no growth).

Vancomycin-Resistant Enterococci
Enterococci are bacteria that are normally present in the human intestines and in the female genital tract and are often found in the environment. These bacteria sometimes cause infections. In some cases, enterococci have become resistant to vancomycin (also known as vancomycin-resistant enterococci or VRE.) Common forms of resistance to vancomycin occur in enterococcal strains that involve the acquisition of a set of genes endoding proteins that direct peptidoglycan precursors to incorporate D-Ala-D-Lac instead of D-Ala-D-Ala. The six different types of vancomycin resistance shown by enterococcus are: Van-A, Van-B, Van-C, Van-D, Van-E and Van-F. In some cases, Van-A VRE is resistant to both vancomycin and teicoplanin, while in other cases, Van-B VRE is resistant to vancomycin but sensitive to teicoplanin; in further cases Van-C is partly resistant to vancomycin, and sensitive to teicoplanin.

As used herein, the term “pharmaceutically acceptable carrier” means a non-toxic, inert solid, semi-solid or liquid filler, diluent, encapsulating material or formulation auxiliary of any type. Some examples of materials which can serve as pharmaceutically acceptable carriers are sugars such as lactose, glucose and sucrose; starches such as corn starch and potato starch; cellulose and its derivatives such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; powdered tragacanth; malt; gelatin; talc; excipients such as cocoa butter and suppository waxes; oils such as peanut oil, cottonseed oil; safflower oil; sesame oil; olive oil; corn oil and soybean oil; glycols; such a propylene glycol; esters such as ethyl oleate and ethyl laurate; agar; buffering agents such as magnesium hydroxide and aluminum hydroxide; alginic acid; pyrogen-free water; isotonic saline; Ringer's solution; ethyl alcohol, and phosphate buffer solutions, as well as other non-toxic compatible lubricants such as sodium lauryl sulfate and magnesium stearate, as well as coloring agents, releasing agents, coating agents, sweetening, flavoring and perfuming agents, preservatives and antioxidants can also be present in the composition, according to the judgment of the formulator. The pharmaceutical compositions described herein can be administered to humans and other animals orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments, or drops), bucally, or as an oral or nasal spray, or a liquid aerosol or dry powder formulation for inhalation.
Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms optionally contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.
Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions are optionally formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation is optionally a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that are optionally employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.
The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.
In order to prolong the effect of a drug, it is often desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This is optionally accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is optionally accomplished by dissolving or suspending the drug in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the drug in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides).

Step 1: To a solution of (S)-methyl 2-((tert-butoxycarbonyl)amino)-3-(4-hydroxyphenyl)propanoate (100 g, 0.323 mol) in acetone (2.0 L) was added K2CO3(37 g, 0.34 mol). After the addition, Mel (32 mL, 0.97 mol) was added dropwise, and the reaction mixture was stirred at room temperature for 72 h and monitored by TLC. The reaction had not yet gone to completion, so NaOH (0.1 eq) was added to the reaction mixture. And after 2 h, the reaction was completed. The solid was filtered and the solvent was removed. The residue was taken up in ethyl acetate and washed with H2O, extracted with ethyl acetate (300 mL×3). The combined organic layers were washed with brine, dried over Na2SO4 and concentrated to give (S)-methyl 2-((tert-butoxycarbonyl)amino)-3-(4-methoxyphenyl)propanoate (100 g, 95.4%).
Step 2: To a solution of (S)-methyl 2-((tert-butoxycarbonyl)amino)-3-(4-methoxyphenyl)propanoate (80 g, 40 g each ×2, run in two separate batches, 259 mmol overall) in methanol (1.5 L in each of the two flasks) was added sequentially Ag2SO4 (85 g, 272 mmol, ½-added to each flask) and I2 (72 g, 283 mmol, ½-added to each flask). The reaction mixture was stirred at room temperature for 2 h. The reaction was monitored by LCMS. When all (S)-methyl 2-((tert-butoxycarbonyl)amino)-3-(4-methoxyphenyl)propanoate had been consumed, then a solution of 10% (w/w) sodium thiosulfate was added until the reaction turned pale yellow. The solid was filtered and most of the methanol was evaporated by rotary evaporation. Water and ethyl acetate were added to each batch. The aqueous layer was extracted with ethyl acetate (3×200 mL). The combined organic layers were washed with brine, dried over sodium sulfate and concentrated. The crude material was combined for the two batches and they were purified together by flash column chromatography on silica gel (25% then 35% then 40% ethyl acetate in hexanes) to give (S)-methyl 2-((tert-butoxycarbonyl)amino)-3-(3-iodo-4-methoxyphenyl)propanoate (97 g, 89%).
Step 3: (S)-Methyl 2-((tert-butoxycarbonyl)amino)-3-(3-iodo-4-methoxyphenyl)propanoate (92 g, 46 g each run in two separate batches, 211 mmol) was dissolved in anhydrous DMSO (1.5 L, ½-added for each batch) under argon and to the solution was added bis(pinacolato) diboron (80.5 g, 317 mmol, ½-added for each batch) and KOAc (103 g, 1.05 mol, ½-added for each batch). This mixture was degassed with argon for twenty minutes, then Pd(dppf)Cl2 (4.6 g, 6 mmol, ½-added for each batch) was added. The mixture was degassed with argon five times, then kept under argon and heated to 80° C. for 3 h. TLC showed that the reaction was complete, and the reaction mixture was cooled to room temperature and filtered. The reaction mixture was dissolved in EA and washed with H2O. The aqueous layer was extracted ethyl acetate (3×200 mL). The combined organic layers were dried over sodium sulfate, filtered and concentrated to give the crude product. The batches were then combined and purified together by flash column chromatography on silica gel (3% ethyl acetate in hexanes, then 20% to 25% ethyl acetate in hexanes to give (S)-methyl 2-((tert-butoxycarbonyl)amino)-3-(4-methoxy-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)propanoate (70 g, 76%).
Step 4: (S)-Methyl 2-((tert-butoxycarbonyl)amino)-3-(4-methoxy-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)propanoate (22 g, 50.6 mmol) was dissolved in dichloromethane (150 mL) and treated with trifluoroacetic acid (50 mL). The reaction mixture was stirred at room temperature and the reaction was monitored by HPLC. When all of the starting material had been consumed, the solvents were evaporated, DCM was added and Na2CO3 was added to neutralize the TFA. The mixture was filtered, and the solution was concentrated. DCM was added to the concentrated oil, and the mixture was cooled at 0° C. for 1 hr, whereupon the solid precipitates that formed were filtered. The filtrate was concentrated to give (S)-methyl 2-amino-3-(4-methoxy-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)propanoate. The material was used without further purification.
Step 1: To a stirred mixture of (S)-2-amino-2-(4-hydroxyphenyl)acetic acid (100 g, 0.6 mol, 1 eq) in a mixture of acetone (400 mL) and water (400 mL) was added di-tert-butyl dicarbonate (130.5 g, 0.6 mol, 1 eq) and NaHCO3 (75.4 g, 0.9 mol, 1.5 eq). The mixture was allowed to stir at 25° C. overnight. After HPLC showed the reaction was complete, the mixture was acidified with 5% citric acid (pH ˜3).
