This application is a 35 U.S.C. §371 national phase application of PCT/US2008/070893 (WO 2009/015208), filed on Jul. 23, 2008, entitled “Antibacterial Amide and Sulfonamide Substituted Heterocyclic Urea Compounds”, which application claims the benefit of U.S. Provisional Application Ser. No. 60/961,634, filed Jul. 23, 2007, and claims benefit of U.S. Provisional Application Ser. No. 61/022,725, filed Jan. 22, 2008, each of which is incorporated herein by reference in its entirety.

The present invention relates to novel heterocyclic urea compounds and in particular to novel amide and sulfonamide substituted heterocyclic urea compounds and to their uses in the treatment of bacterial infections.

Antibacterials kill or inhibit the growth of bacteria by interfering with major processes of cellular function that are essential for survival. The development of antibacterial agents has significantly reduced the morbidity and mortality associated with bacterial infections over the last century, particularly in developed countries. However, the emergence of drug-resistant bacterial strains threatens the resurgence of bacterial-borne diseases long thought to have been conquered.

Resistance to antibacterials can occur when the target of a drug mutates so that it can still function, but is no longer inhibited by the drug (e.g., mutations in the quinolone resistance determining regions of bacterial gyrases and topisomerase enzymes that confer resistance to the fluoroquinolones). In a recent congressional report, the General Accounting Office (GAO) has summarized the current and future public health burden resulting from drug-resistant bacteria (Antimicrobial Resistance (1999). General Accounting Office (GAO/RCED-99-132)). According to this report, the number of patients treated in a hospital setting for an infection with drug-resistant bacteria has doubled from 1994 to 1996 and again almost doubled from 1996 to 1997. The same GAO report also provides clear evidence that previously susceptible bacteria are increasingly becoming resistant and spreading around the world. As a consequence of the increase and prevalence of resistant bacteria there is a growing need to identify new antibacterial agents.

It has now been found that amide and sulfonamide substituted heterocyclic urea compounds are useful in the treatment of bacterial infections. The present invention relates to these antibacterial compounds and salts thereof, pharmaceutical compositions comprising these compounds and methods of use thereof in the treatment of bacterial infections, including resistant bacterial infections.

In one aspect the invention provides compounds of Formula (I):

in which:

R₁is selected from the group consisting of a substituted or unsubstituted aryl, substituted or unsubstituted arylalkyl and substituted or unsubstituted heteroaryl;

X is selected from the group consisting of a C and N atom;

Y is selected from the group consisting of CO and SO₂;

R₂, R₃and R₄are independently selected from the group consisting of, H, OH, substituted or unsubstituted aryl, substituted or unsubstituted arylalkyl, substituted or unsubstituted linear, cyclic or branched alkyl, cyano, and perfluoroalkyl;

and further, optionally

wherein R₂, R₄, Y, and N together can form a substituted or unsubstituted 4-7 member saturated ring;

or alternatively, optionally

wherein R₂, R₃and N together can form a substituted or unsubstituted 4-7 member saturated ring; and

R₅is selected from the group consisting of H, halogen, alkyl, cyano and null, wherein R₅is null when X is N.

These and various other features as well as advantages which characterize the invention will be apparent from a reading of the following detailed description and a review of the appended claims.

The present invention relates to antibacterial compounds and salts thereof, pharmaceutical compositions comprising these compounds and methods of use thereof. The compounds of the present invention are useful in the protection of patients from bacterial infections, including antibiotic resistant bacterial infections.

The bond to the parent moiety is through the carbonyl. Preferred acyls contain a lower alkyl. Non-limiting examples of suitable acyl groups include formyl, acetyl and propanoyl.

When used herein, the term “substituted” means that one or more hydrogens on the designated atom is replaced with a selection from the indicated group, provided that the designated atom's normal valency under the existing circumstances is not exceeded, and that the substitution results in a stable compound. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds. By “stable compound” or “stable structure” is meant a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent. The term “optionally substituted” means optional substitution with the specified groups, radicals or moieties.

It should also be noted that any heteroatom with unsatisfied valences in the text, schemes, examples and Tables herein is assumed to have the hydrogen atom to satisfy the valences. When a functional group in a compound is termed “protected”, this means that the group is in modified form to preclude undesired side reactions at the protected site when the compound is subjected to a reaction. Suitable protecting groups will be recognized by those with ordinary skill in the art as well as by reference to standard textbooks such as, for example, T. W. Greene et al, Protective Groups in Organic Synthesis (1991), Wiley, N.Y.

When any variable (e.g., aryl, heterocycle, R₂, 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.

When used herein, the term “composition” is intended to encompass a product comprising the specified ingredients in the specified amounts, as well as any product which results, directly or indirectly, from combination of the specified ingredients in the specified amounts.

The compounds according to the invention are suitably provided in substantially pure form, for example at least 50% pure, suitably at least 60% pure, advantageously at least 75% pure, preferably at least 85% pure, more preferably at least 95% pure, especially at least 98% pure, all percentages being calculated as weight/weight. An impure or less pure form of a compound according to the invention may, for example, be used in the preparation of a more pure form of the same compound or of a related compound (for example a corresponding derivative) suitable for pharmaceutical use.

It will be appreciated that certain compounds of the present invention may comprise one or more chiral centers so that compounds may exist as stereoisomers, including diastereoisomers and enantiomers. The present invention covers all such stereoisomers, and mixtures thereof, including racemates.

Prodrugs and solvates of the compounds of the invention are also contemplated herein. The term “prodrug”, as employed herein, denotes a compound that is a drug precursor which, upon administration to a subject, undergoes chemical conversion by metabolic or chemical processes to yield a compound of Formula (I) (note that Formula (I) includes Formula (Ia) and Formula (Ib)) or a salt and/or solvate thereof. A discussion of prodrugs is provided in T. Higuchi and V. Stella, Pro-drugs as Novel Delivery Systems (1987) 14 of the A.C.S. Symposium Series, and in Bioreversible Carriers in Drug Design, (1987) Edward B. Roche, ed., American Pharmaceutical Association and Pergamon Press, both of which are incorporated herein by reference thereto.

When used herein, the term “solvate” means a physical association of a compound of this invention with one or more solvent molecules. This physical association involves varying degrees of ionic and covalent bonding, including hydrogen bonding. In certain instances the solvate will be capable of isolation, for example when one or more solvent molecules are incorporated in the crystal lattice of the crystalline solid. “Solvate” encompasses both solution-phase and isolatable solvates. Non-limiting examples of suitable solvates include ethanolates, methanolates, and the like.

When used herein, the term “hydrate” is a solvate wherein the solvent molecule is H₂O.

As used herein, the phrases “effective amount” or “therapeutically effective amount” are meant to describe an amount of compound or a composition of the present invention effective in inhibiting bacterial replication and thus producing the desired therapeutic, ameliorative, inhibitory or preventative effect.

The compounds of Formula (I) (as defined herein Formula (I) includes Formula (Ia) and (1b)) can form salts which are also within the scope of this invention. Reference to a compound of Formula (I) herein is understood to include reference to salts thereof, unless otherwise indicated. The term “salt(s)”, as employed herein, denotes acidic salts formed with inorganic and/or organic acids, as well as basic salts formed with inorganic and/or organic bases. In addition, when a compound of Formula (I) contains both a basic moiety, such as, but not limited to a pyridine or imidazole, and an acidic moiety, such as, but not limited to a carboxylic acid, zwitterions (“inner salts”) may be formed and are included within the term “salt(s)” as used herein. Pharmaceutically acceptable (i.e., non-toxic, physiologically acceptable) salts are preferred, although other salts are also useful. Salts of the compounds of the Formula (I) may be formed, for example, by reacting a compound of Formula (I) with an amount of acid or base, such as an equivalent amount, in a medium such as one in which the salt precipitates, or in an aqueous medium followed by lyophilization.

Exemplary acid addition salts include acetates, ascorbates, benzoates, benzenesulfonates, bisulfates, borates, butyrates, citrates, camphorates, camphorsulfonates, fumarates, hydrochlorides, hydrobromides, hydroiodides, lactates, maleates, methanesulfonates, naphthalenesulfonates, nitrates, oxalates, phosphates, propionates, salicylates, succinates, sulfates, tartarates, thiocyanates, toluenesulfonates (also known as tosylates,) and the like. Additionally, acids which are generally considered suitable for the formation of pharmaceutically useful salts from basic pharmaceutical compounds are discussed, for example, by S. Berge et al, Journal of Pharmaceutical Sciences (1977) 66(1) 1 19; P. Gould, International J. of Pharmaceutics (1986) 33 201 217; Anderson et al, The Practice of Medicinal Chemistry (1996), Academic Press, New York; and in The Orange Book (Food & Drug Administration, Washington, D.C. on their website). These disclosures are incorporated herein by reference thereto.

Exemplary basic salts include ammonium salts, alkali metal salts such as sodium, lithium, and potassium salts, alkaline earth metal salts such as calcium and magnesium salts, salts with organic bases (for example, organic amines) such as dicyclohexylamines, t-butyl amines, and salts with amino acids such as arginine, lysine and the like. Basic nitrogen-containing groups may be quarternized with agents such as lower alkyl halides (e.g. methyl, ethyl, and butyl chlorides, bromides and iodides), dialkyl sulfates (e.g. dimethyl, diethyl, and dibutyl sulfates), long chain halides (e.g. decyl, lauryl, and stearyl chlorides, bromides and iodides), arylalkyl halides (e.g. benzyl and phenethyl bromides), and others.

All such acid and base salts are intended to be pharmaceutically acceptable salts within the scope of the invention and all acid and base salts are considered equivalent to the free forms of the corresponding compounds for purposes of the invention.

Compounds of Formula (I) and salts, solvates and prodrugs thereof, may exist in their tautomeric form (for example, as an amide or imino ether). All such tautomeric forms are contemplated herein as part of the present invention. All stereoisomers (for example, geometric isomers, optical isomers and the like) of the present compounds (including those of the salts, solvates and prodrugs of the compounds as well as the salts and solvates of the prodrugs), such as those which may exist due to asymmetric carbons on various substituents, including enantiomeric forms (which may exist even in the absence of asymmetric carbons), rotameric forms, atropisomers, and diastereomeric forms, are contemplated within the scope of this invention, as are positional isomers (such as, for example, 4-pyridyl and 3-pyridyl). Individual stereoisomers of the compounds of the invention may, for example, be substantially free of other isomers, or may be admixed, for example, as racemates or with all other, or other selected, stereoisomers. The chiral centers of the present invention can have the S or R configuration as defined by the IUPAC 1974 Recommendations. The use of the terms “salt”, “solvate” “prodrug” and the like, is intended to equally apply to the salt, solvate and prodrug of enantiomers, stereoisomers, rotamers, tautomers, positional isomers, racemates or prodrugs of the inventive compounds.

Compounds of Formula (I) are inhibitors of PolC, a type II DNA Polymerase III, which is the major replicative polymerase responsible for chromosomal replication in low GC Gram-positive bacteria. Compounds of Formula (I) are generally selective for PolC, showing little or no inhibition of the eukaryotic replicative polymerase, i.e., provides an optimal combination of high activity against various pathogenic bacteria and low or no activity against mammalian calls, allowing the use of compounds of the invention in the treatment of mammals, and in particular humans.

Compounds of the present invention show antibacterial activity against clinically relevant Gram-positive pathogens, including S. pyogenes, S. aureus, S. pneumoniae and E. faecalis. Compounds of the present invention demonstrate preferential inhibition of DNA synthesis over RNA, protein, or cell wall synthesis in whole cell assays. Therapeutic compositions of the present invention have antibacterial activity against clinically important Gram-positive pathogens, including staphylococci and streptococci, and particularly including isolates resistant to currently marketed agents.

Another aspect of this invention is a method of protecting a patient from a bacterial infection. A patient may be an animal, preferably a mammal and even more preferably a human having or susceptible to a disease or condition associated with a bacterial infection. Protecting may be prophylactic, i.e., administering a compound of the present invention in the absence of a diagnosed bacterial infection, or therapeutic, i.e., administering a compound of the present invention upon diagnosis of a bacterial infection. Protection may be achieved by administering a therapeutically effective amount of at least one compound of Formula (I), or a pharmaceutically acceptable salt or solvate of said compound to the patient. A preferred dosage is about 0.001 to 500 mg/kg of body weight/day of the compound of Formula (I) or a pharmaceutically acceptable salt or solvate of said compound. An especially preferred dosage is about 0.01 to 25 mg/kg of body weight/day of a compound of Formula (I), or a pharmaceutically acceptable salt or solvate of said compound.

Methods to diagnose bacterial infection in patients are known in the art. Preferred bacterial infections to treat include bacterial infections caused by any bacteria type or species against which the compounds of the present invention have an antibacterial effect. Particularly preferred bacteria types or species include Gram-positive and Gram-negative bacteria and most preferred bacterial types include Gram-positive bacteria.

In order to protect an animal from bacterial infection, a therapeutic or prophylactic composition of the present invention is administered to the animal in an effective manner such that bacterial infection is minimized and/or reduced. Preferably, the bacterial infection and/or bacterial burden of the infectious bacteria is reduced by at least about 50%, at least about 70%, and more preferably at least about 90%, 95% or 97%.

Suitable patients to treat include humans; birds such as chickens, ostriches, quail, and turkeys; other mammals such as companion animals (including dogs, cats, and rodents) and economic food and/or fur or other product animals, such as horses, cattle, llamas, chinchillas, ferrets, goats, sheep, rodents, minks, rabbits, raccoons, and swine.

The compounds of this invention can also be useful in combination (administered together or sequentially) with one or more of antibacterial treatments, such as, for example, treatment with other known antibacterial drug classes such as, for example, β-lactams, glycopeptides, oxazolidinones, macrolides, ketolides, quinolones, fluoroquinolones, aminoglycosides, tetracyclines, and lipopeptides. If formulated as a fixed dose, such combination products employ the compounds of this invention within the dosage range described herein and the other pharmaceutically active agent or treatment within its dosage range. Compounds of Formula (I) may also be administered sequentially with known antibacterial agents when a combination formulation is inappropriate. The invention is not limited in the sequence of administration; compounds of Formula (I) may be administered either prior to or after administration of the known antibacterial agent. Such techniques are within the skills of persons skilled in the art as well as attending physicians.

Accordingly, in an aspect, this invention includes combinations comprising an amount of at least one compound of Formula (I), or a pharmaceutically acceptable salt or solvate thereof, and an amount of one or more antibacterial agents or treatments listed above wherein the amounts of the compounds/treatments result in desired therapeutic effect. The pharmacological properties of the compounds of this invention may be confirmed by a number of pharmacological assays. The exemplified pharmacological assays which are described herein have been carried out with compounds according to the invention and/or their salts.

In another aspect, the invention includes pharmaceutical compositions which comprise at least one compound of Formula (I), or a pharmaceutically acceptable salt or solvate of said compound, and at least one pharmaceutically acceptable carrier. Accordingly, the present invention further includes compositions comprising one or more compounds of Formula (I) and a pharmaceutically acceptable carrier.

When used herein, the phrase “pharmaceutically acceptable carrier” refers to media generally accepted in the art for the delivery of biologically active agents to patients, in particular, mammals Pharmaceutically acceptable carriers are typically formulated according to a number of factors well within the purview of those of ordinary skill in the art. These include, without limitation: the type and nature of the active agent being formulated; the subject to which the agent-containing composition is to be administered; the intended route of administration of the composition; and, the therapeutic indication being targeted. Pharmaceutically acceptable carriers include both aqueous and non-aqueous liquid media, as well as a variety of solid and semi-solid dosage forms. Such carriers can include a number of different ingredients and additives in addition to the active agent, such additional ingredients being included in the formulation for a variety of reasons, e.g., stabilization of the active agent, binders, etc., well known to those of ordinary skill in the art. Descriptions of suitable pharmaceutically acceptable carriers, and factors involved in their selection, are found in a variety of readily available sources such as, for example, Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., 1985, which is incorporated herein by reference in its entirety.

Liquid form preparations may also include solutions for intranasal administration. Gelatin capsules can be used to contain the active ingredient and a suitable carrier such as, but not limited to, lactose, starch, magnesium stearate, steric acid, or cellulose derivatives. Similar diluents can be used to make compressed tablets. Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of time. Compressed tablets can be sugar-coated or film-coated to mask any unpleasant taste, or used to protect the active ingredients from the atmosphere, or to allow selective disintegration of the tablet in the gastrointestinal tract. Liquid dose forms for oral administration can also contain coloring or flavoring agents to increase patient acceptance.

Typically, water, pharmaceutically acceptable oils, saline, aqueous dextrose, and related sugar solutions and glycols, such as propylene glycol or polyethylene glycol, are suitable carriers for parenteral solutions. Solutions for parenteral administration can contain, for example, a water soluble salt of the active ingredient and suitable stabilizing agent(s). Antioxidizing agents, such as sodium bisulfite, sodium sulfite, or ascorbic acid, either alone or in combination, can act as suitable stabilizing agents. Also suitable as stabilizing agents are citric acid and its salts, and EDTA. In addition, parenteral solutions can contain preservatives such as, for example, benzalkonium chloride, methyl- or propyl-paraben, and chlorobutanol.

Oral compositions are preferred and will generally include an inert diluent or an edible carrier and may be compressed into tablets or enclosed in gelatin capsules. The oral dosage forms are administered to the patient weekly, twice weekly, three times weekly, four times weekly, five times weekly, six times weekly, or 1, 2, 3, or 4 times daily. It is preferred that the compounds of the invention be administered either three or fewer times daily, more preferably once or twice daily. For purposes of oral therapeutic administration, the active compound or compounds can be incorporated with excipients and used in the form of tablets, capsules, lozenges, or troches. Pharmaceutically compatible binding agents and adjuvant materials can be included as part of the composition. The tablets, pills, capsules, troches, and the like can contain any of the following ingredients or compounds of a similar nature: a binder such as, but not limited to, gum tragacanth, acacia, corn starch, or gelatin; an excipient such as microcrystalline cellulose, starch, or lactose; a disintegrating agent such as, but not limited to, alginic acid and corn starch; a lubricant such as, but not limited to, magnesium stearate; a glidant, such as, but not limited to, colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; and a flavoring agent such as peppermint, or fruit flavoring.

When the dosage unit form is a capsule, it can contain, in addition to material of the above type, a liquid carrier such as a fatty oil. In addition, dosage unit forms can contain various other materials, which modify the physical form of the dosage unit, for example, coatings of sugar and other enteric agents. The compounds can also be administered as a component of an elixir, suspension, syrup, wafer, chewing gum or the like. A syrup may contain, in addition to the active compounds, sucrose as a sweetening agent and certain preservatives, dyes, colorings, and flavors. The active materials can also be mixed with other active materials that do not impair the desired action, or with materials that supplement the desired action.

Solutions or suspensions used for parenternal, intradermal, subcutaneous, or topical application can include any of the following components: a sterile diluent such as water for injection, saline solution, fixed oil, a naturally occurring vegetable oil such as sesame oil, coconut oil, peanut oil, cottonseed oil, and the like, or a synthetic fatty vehicle such as ethyl oleate, and the like, polyethylene glycol, glycerine, propylene glycol, or other synthetic solvent; antimicrobial agents such as benzyl alcohol and methyl parabens; antioxidants such as ascorbic acid and sodium bisulfite; chelating agents such as ethylenediaminetetraacetic acid (EDTA); buffers such as acetates, citrates, and phosphates; and agents for the adjustment of tonicity such as sodium chloride and dextrose. Parenternal preparations can be enclosed in ampoules, disposable syringes, or multiple dose vials made of glass, plastic, or other suitable material. Buffers, preservatives, antioxidants, and the like can be incorporated as required.

Where administered intravenously, suitable carriers include physiological saline, phosphate buffered saline (PBS), and solutions containing thickening and solubilizing agents such as glucose, polyethylene glycol, polypropyleneglycol, and mixtures thereof. Liposomal suspensions including tissue-targeted liposomes may also be suitable as pharmaceutically acceptable carriers.
