Described herein are carbapenem compounds, their stereoisomers, pharmaceutically acceptable salts or N-oxides thereof, which may be useful for the treatment of bacterial infections, particularly drug-resistant bacterial infections. Also described herein are the processes for the preparation of compounds, the pharmaceutical compositions of these compounds and their use in the treatment of bacterial infection.
Antimicrobial resistance is the most important crisis in the antibacterial therapy. One of the mechanisms of resistance development is due to enzymes, which deactivate certain class of antibiotics by hydrolysis, e.g. β-lactam ring of β-lactam antibiotics. In the mid 1980's, it was found that the enzymes which are responsible for the deactivation of the β-lactams are β-lactamases, particularly Extended Spectrum β-Lactamase (ESBL). ESBL is produced mainly by Enterobacteriaceae group (Chaudhary et al., Indian Journal of Medical Microbiology, 2004, 22(2), 75-80, Extended Spectrum β-Lactamases (ESBL)—An Emerging Threat to Clinical Therapeutics).
The risk factors involved in the expression of ESBL are increased length of hospitalization or ICU stay, increased severity of illness, use of a central venous or arterial catheter or urinary catheter, ventilatory support, hemodialysis, emergency abdominal surgery, gastrostomy or jejunostomy, gut colonization, prior administration of antibiotics, particularly of oxyimino-β-lactams (Falagas et al., Journal of Antimicrobial Chemotherapy, 2007, 60, 1124-1130, Risk factors of carbapenem-resistant Klebsiella pneumoniae infections: a matched case—control study).
The antibiotics which are used as a last resort because of their broad spectrum of antimicrobial activity are carbapenems. Carbapenems such as Imipenem (U.S. Pat. No. 4,194,047 A), Meropenem (European Pat. No. EP0126587 B1), Ertapenem (European Pat No. EP0579826 B1) and Doripenem (European Pat. No. EP0528678 B1) are ultrabroad spectrum injectable antibiotics. These antibiotics give rise to cell death by binding to penicillin-binding proteins (PBPs) and inhibiting cell wall biosynthesis. The emergence of carbapenemases belonging to class A and class D β-lactamases threatens their clinical utility.
It has been reported that the presence of a hydroxyethyl side chain in carbapenems provides stability to these compounds. (Sumita, Y et al., Journal of Antibiotics, 1995, 48(2), 188-190).
Sunagawa M et al., Journal of Antibiotics, 1997, 50(7), 621-627, discloses carbapenem compounds having antimicrobial activity.
Carbapenem compounds with potency against carbapenem-resistant gram negative bacteria have not been reported. Therefore, the development of a novel carbapenem compound with broad antibacterial spectrum, preferably a compound possessing potent activity against resistant bacteria which produce β-lactamase is desirable.
Still there remains a huge unmet medical need for new antimicrobial agents due to the emerging bacterial resistance over the current therapies.
The objective of the present invention is to provide carbapenem compounds, their stereoisomers, pharmaceutically acceptable salts or N-oxides thereof.
Yet another objective of the present invention is to provide processes for the preparation of Carbapenem compounds and pharmaceutical compositions containing these compounds.
A further objective of the present invention is to provide a method for preventing or treating bacterial infection and to provide carbapenem compounds as broad spectrum antibacterial agents.

Another embodiment of the present invention is a compound of Formula I, or a pharmaceutically acceptable salt thereof, as originally defined or as defined in any of the foregoing embodiments, sub-embodiments, aspects, classes or sub-classes, wherein the compound or its salt is in a substantially pure form. As used herein “substantially pure” means suitably at least about 60 wt. %, typically at least about 70 wt %, preferably at least about 80 wt. %, more preferably at least about 90 wt. % (e.g., from about 90 wt. % to about 99 wt. %), even more preferably at least about 95 wt. % (e.g., from about 95 wt. % to about 99 wt. %, or from about 98 wt. % to 100 wt. %), and most preferably at least about 99 wt. % (e.g., 100 wt. %) of a product containing a compound of Formula I or its salt (e.g., the product isolated from a reaction mixture affording the compound or salt) consists of the compound or salt. The level of purity of the compounds and salts can be determined using a standard method of analysis such as thin layer chromatography, gel electrophoresis, high performance liquid chromatography, and/or mass spectrometry. If more than one method of analysis is employed and the methods provide experimentally significant differences in the level of purity determined, then the method providing the highest level of purity governs. A compound or salt of 100% purity is one which is free of detectable impurities as determined by a standard method, of analysis.
Recitation or depiction of a specific compound in the claims (i.e., a species) without a specific stereoconfiguration designation, or with such a designation for less than all chiral centers, is intended to encompass the racemate, racemic mixtures, each individual enantiomer, a diastereoisomeric mixture and each individual diastereomer of the compound where such forms are possible due to the presence of one or more asymmetric centers:
With respect to a compound of the invention which has one or more asymmetric centers and can occur as mixtures of stereoisomers, a substantially pure compound can be either a substantially pure mixture of the stereoisomers or a substantially pure individual diastereomer or enantiomer. All isomeric forms of these compounds, whether individually or in mixtures, are within the scope of the present invention.
When any variable (e.g., R1, Ra, etc.) occurs more than one time in any constituent or in formula I, its definition on each occurrence is independent of its definition at every other occurrence. Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds. A squiggly line across a bond ii a substituent variable represents the point of attachment.
Under standard nomenclature used throughout this disclosure, the terminal portion of the designated side chain is described last, preceded by the adjacent functionality toward the point of attachment.
In choosing compounds of the present invention, one of ordinary skill in the art will recognize that the various substituents, i.e. R1, R2, etc., are to be chosen in conformity with well-known principles of chemical structure connectivity and stability.
The term “substituted” shall be deemed to include multiple degrees of substitution by a named substituent. Where multiple substituent moieties are disclosed or claimed, the substituted compound can be independently substituted by one or more of the disclosed or claimed substituent moieties, singly or plurally. By independently substituted, it is meant that the (two or more) substituents can be the same or different.
When a group, e.g., C1-8alkyl, is indicated as being substituted, such substitutions can also be occur where such group is part of a larger substituent, e.g., —C1-8alkyl-C3-7cycloalkyl and —C1-8alkyl-aryl.
In the compounds of formula I, the atoms may exhibit their natural isotopic abundances, or one or more of the atoms may be artificially enriched in a particular isotope-having the same atomic number, but an atomic mass or mass number different from the atomic mass or mass number predominantly found in nature. The present invention is meant to include all suitable isotopic variations of the compounds of formula I. For example, different isotopic forms of hydrogen (H) include protium (1H) and deuterium (2H or D). Protium is the predominant hydrogen isotope found in nature. Enriching for deuterium may afford certain therapeutic advantages, such as increasing in vivo half-life or reducing dosage requirements, or may provide a compound useful as a standard for characterization of biological samples. Isotopically-enriched compounds within formula I can be prepared without undue experimentation by conventional techniques well known to those skilled in the art or by processes analogous to those described in the EXAMPLES herein using appropriate isotopically-enriched reagents and/or intermediates.
Unless expressly stated to the contrary in a particular context, any of the various cyclic rings and ring systems described herein may be attached to the rest of the compound at any ring atom (i.e., any carbon atom or any heteroatom) provided that a stable compound results.
Unless expressly stated to the contrary, all ranges cited herein are inclusive. For example, a heteroaromatic ring described as containing from “1 to 4 heteroatoms” means the ring can contain 1, 2, 3 or 4 heteroatoms. It is also to be understood that any range cited herein includes within its scope all of the sub-ranges within that range. Thus, for example, a heterocyclic ring described as containing from “1 to 4 heteroatoms” is intended to include as aspects thereof, heterocyclic rings containing 2 to 4 heteroatoms, 3 or 4 heteroatoms, 1 to 3 heteroatoms, 2 or 3 heteroatoms, 1 or 2 heteroatoms, 1 heteroatom, 2 heteroatoms, 3 heteroatoms, and 4 heteroatoms. Similarly, C1-6 when used with a chain, for example an alkyl chain, means that the chain can contain 1, 2, 3, 4, 5 or 6 carbon atoms. It also includes all ranges contained therein including C1-5, C1-4, C1-3, C1-2, C2-6, C3-6, C4-6, C5-6, and all other possible combinations.
A “stable” compound is a compound which can be prepared and isolated and whose structure and properties remain or can be caused to remain essentially unchanged for a period of time sufficient to allow use of the compound for the purposes described herein (e.g., therapeutic administration to a subject). The compounds of the present invention are limited to stable compounds embraced by Formula I.
The term “compound” refers to the free compound and, to the extent they are stable, any hydrate or solvate thereof. A hydrate is the compound complexed with water, and a solvate is the compound complexed with an organic solvent.
As indicated above, the compounds of the present invention can be employed in the form of pharmaceutically acceptable salts. The term “pharmaceutically acceptable salt” refers to a salt which possesses the effectiveness of the parent compound and which is not biologically or otherwise undesirable (e.g., is neither toxic nor otherwise deleterious to the recipient thereof). A pharmaceutically acceptable salt can be formed, for example, by treating the compound of the invention (e.g., a compound of Formula I) with one molar equivalent of a mild base (e.g., sodium carbonate, sodium bicarbonate, potassium bicarbonate, or sodium acetate). In this case, M is a cation, such as Na+ in the event of treatment with a sodium base.
Described herein are also prodrugs of a compound of the invention, which on administration undergo chemical conversion by metabolic processes before becoming active pharmacological substances. In general, such prodrugs will be functional derivatives of a compound of the invention that are readily convertible in vivo into compound of formula (I).
As set forth above, the present invention includes pharmaceutical compositions comprising a compound of Formula I of the present invention, optionally one or more other active components, and a pharmaceutically acceptable carrier. The characteristics of the carrier will depend on the route of administration. By “pharmaceutically acceptable” is meant that the ingredients of the pharmaceutical composition must be compatible with each other; do not interfere with the effectiveness of the active ingredient(s), and are not deleterious (e.g., toxic) to the recipient thereof. Thus, compositions according to the invention may, in addition to the inhibitor, contain diluents, fillers, salts, buffers, stabilizers, solubilizers, and other materials well known in the art.
Also as set forth above, the present invention includes a method for treating a bacterial infection which comprises administering to a subject in need of such treatment a therapeutically effective amount of a compound of Formula I, or a pharmaceutically acceptable salt thereof. The term “subject” (or, alternatively, “patient”) as used herein refers to an animal, preferably a mammal, most preferably a human, who has been the object of treatment, observation or experiment. The term “administration” and variants thereof (e.g., “administering” a compound) in reference to a compound of Formula I mean providing the compound, or a pharmaceutically acceptable salt thereof, to the individual in need of treatment. When a compound or a salt thereof is provided in combination with one or more other active agents, “administration” and its variants are each understood to include provision of the compound or its salt and the other agents at the same time or at different times. When the agents of a combination are administered at the same time, they can be administered together in a single composition or they can be administered separately. It is understood that a “combination” of active agents can be a single composition containing all of the active agents or multiple compositions each containing one or more of the active agents. In the case of two active agents a combination can be either a single composition comprising both agents or two separate compositions each comprising one of the agents; in the case of three active agents a combination can be either a single composition comprising all three agents, three separate compositions each comprising one of the agents, or two compositions one of which comprises two of the agents and the other comprises the third agent; and so forth.
The compositions and combinations of the present invention are suitably administered in effective amounts. The term “effective amount” as used herein with respect to a nargenicin compound means the amount of active compound sufficient to inhibit DnaE and/or cause a bacteriocidal or bacteriostatic effect. In one embodiment, the effective amount is a “therapeutically effective amount” meaning the amount of active compound that can overcome bacterial drug resistance and which is sufficient to inhibit bacterial replication and/or result in bacterial killing. When the active compound (i.e., active ingredient) is administered as the salt, references to the amount of active ingredient are to the free acid or free base form of the compound.
The administration of a composition of the present invention is suitably parenteral, oral, sublingual, transdermal, topical, intranasal, intratracheal, intraocular, or intrarectal, wherein the composition is suitably formulated for administration by the selected route using formulation methods well known in the art, including, for example, the methods for preparing and administering formulations described in chapters 39, 41, 42, 44 and 45 in Remington—The Science and Practice of Pharmacy, 21st edition, 2006. In one embodiment, compounds of the invention are administered intravenously in a hospital setting. In another embodiment, administration is oral in the form of a tablet or capsule or the like. The dosage of the compounds of the invention and of their pharmaceutically acceptable salts may vary within wide limits and should naturally be adjusted, in each particular case, to the individual conditions and to the pathogenic agent to be controlled. In general, for a use in the treatment of bacterial infections, the daily dose may be between 0.005 mg/kg to 100 mg/kg, 0.01 mg/kg to 10 mg/kg, 0.05 mg/kg to 5 mg/kg, 0.05 mg/kg to 1 mg/kg. For oral administration, the compositions are preferably provided in the form of tablets containing 1.0 to 1000 mg of the active ingredient, particularly 1.0, 5.0, 10.0, 15.0, 20.0, 25.0, 50.0, 75.0, 100.0, 150.0, 200.0, 250.0, 300.0, 400.0, 500.0, 600.0, 750.0, 800.0, 900.0, and 1000.0 mg of the active ingredient for the symptomatic adjustment of the dosage to the patient to be treated. The compounds may be administered on a regimen of 1 to 4 times per day, preferably once or twice per day.

Thus, in some embodiments, the formulation can be prepared in a dosages form, such as but not limited to, a tablet, capsule, liquid (solution or suspension), suppository, ointment, cream, or aerosol. In some embodiments, the presently disclosed subject matter provides such compounds and/or formulations that have been lyophilized and that can be reconstituted to form pharmaceutically acceptable formulations for administration, for example, as by intravenous or intramuscular injection.
Intravenous administration of a compound of the invention can be conducted by reconstituting a powdered form of the compound with an acceptable solvent. Suitable solvents include, for example, saline solutions (e.g., 0.9% Sodium. Chloride Injection) and sterile water (e.g., Sterile Water for Injection, Bacteriostatic Water for Injection with methylparaben and propylparaben, or Bacteriostatic Water for Injection with 0.9% benzyl alcohol). The powdered form of the compound can be obtained by gamma-irradiation of the compound or by lyophilization of a solution of the compound, after which the powder can be stored (e.g., in a sealed vial) at or below room temperature until it is reconstituted. The concentration of the compound in the reconstituted IV solution can be, for example, in a range of from about 0.1 mg/mL to about 20 mg/mL.

To this solution was added the thiol (0.372 g, 0.65 mmol) at 0° C. under N2 atmosphere followed by addition of diisopropylethylamine (0.2 mL, 1.15 mmol). The resultant solution was degassed again for 15 minutes. The reaction mixture was stirred under N2 at 0° C. for 2 hours. After the completion of reaction, the reaction mixture was quenched using water and extracted by ethyl acetate. The organic layer was then washed with water, brine, dried over sodium sulphate and evaporated under vacuum to give the crude. The crude reaction mixture was purified by column chromatography to give the product (450 mg, 64%) as a solid.
