However, there have been relatively few new agents discovered in the last 40 years to treat TB [Aristoff, et al., Tuberculosis 90, 94-118 (2010), Koul., et al., Nature 469, 483-490 (2100)]. Among the most used TB drugs are rifampin and its analogs, isoniazid, pyrazinamide, ethambutol and fluoroquinolone. The drug pipeline today is relatively thin with only 10 new or repurposed drugs in clinical trials [Zumla, et al, Nat. Rev.

MDR-TB is resistant to isoniazid and rifampin, the two drugs that are used commonly for drug-susceptible TB and with treatment-adherent TB patients. MDR-TB that has also developed resistance to one of the injectable second line TB drugs (kanamycin, capreomycin or amikacin) and also to a fluoroquinolone drug is classed as XDR-TB. XDR-TB can be treated with other second-line TB drugs, but the treatment is more difficult, more expensive and there may be more side effects. XXDR-TB is resistant to both first line and second line TB drugs and is extremely difficult to treat. In general, treatment for all drug-resistant TB can be complicated, lengthy and may be problematic, in part because of issues of toxicity.
Our research work on retroviral integrase inhibitors has led to the discovery of highly active compounds against a diverse set of primary HIV-1 isolates [Nair, et al, US 2012 0282218 Al, Nair, et al, PCT International Patent Application No. WO 2011/071849 A2, Nair, et al, ASM ICAAC Conference H2-801(2011)]. In investigating the molecular modeling details of the mechanism of action of our active integrase inhibitors, it was apparent that these inhibitors had one common feature, i.e., they were all interacting with the DDE catalytic triad and also with two divalent magnesium ions in the catalytic core domain of HIV integrase. The DDE motif is essential for integrase catalysis [Nair, et al, Rev. Med. Virol. 17, 277-295 (2007), Nair, et al, J. Med. Chem. 49, 445-447 (2006), Frankel, et al, Annu. Rev. Biochem. 67, 1-25 (1998)]. However, our best integrase inhibitors of this class, while exhibiting potent anti-HIV activity [Nair, et al, US 2012 0282218 Al, Nair, et al, PCT International Patent Application No. WO 2011/071849 A2, Nair, et al, ASM ICAAC
Conference H2-801(2011], did not show as compelling a level of anti-MDR TB activity as the novel compounds of the current invention.
The catalytic core domain of DNA-dependent RNA polymerase (RNAP) of bacteria is conserved among cellular organisms [Archambault, et al, Microbiol. Mol. Biol Rev. 57, 703- 724 (1993)]. Examination of the crystal structure [Zhang, et al, Cell 98, 811-824 (1999)] of the RNAP of Thermus acquaticus (a model for TB RNAP), with bound rifampin, a first-line drug for TB, shows that rifampin binds to the β-site on the RNAP and inhibits RNA synthesis by blocking the path of the elongating RNA, which is believed to be its mechanism of action [Campbell, et al, Cell 104, 901-912 (2001)]. However, there are other sites existing on TB RNAP that could be targeted by inhibitors to interfere with this RNAP's functional mechanism. For example, there is a pocket on the TB RNAP catalytic core domain that contains a structural region that bears some resemblance to the catalytic triad area of the catalytic core domain of HIV-1 integrase [Frankel, et al, Annu. Rev. Biochem. 67, 1-25 (1998), Cox and Nair, Antimicrob. Agents Chemother. 17, 343-353 (2006)]. This is the β'- site of this RNAP, which is close to 18 A away from the binding location of rifampin in the β-site. Computational chemical biology and molecular modeling experiments revealed that our novel anti-TB compounds described in this invention are capable of binding inside the catalytic channel of the RNAP β'-pocket, interacting with a Mg 2+ ion and a number of other residues in the β'-pocket, as well as with a few residues that are in the structural region that forms the interface between β'- and β-pockets. Our compounds appear to bind to the TB RNAP holoenzyme either before or after binding of the promoter DNA, which produces obstruction of transcription, resulting in failure of RNAP catalysis to initiate transcription. It is relevant to state that our compounds are not alternate substrates or transition state mimics of the RNAP polymerization reaction.
The new class of compounds described in this invention are multifunctional and are designed with the following structural components: dibenzyl pyridinone scaffold, diketo- enolic functionality, and a piperazine carboxamide moiety that carries an aromatic or substituted aromatic group on the second piperazine nitrogen. The compounds have been designed as treatments for MDR-TB and have therapeutic applications in XDR-TB and XXDR-TB. An example is shown below (Figure 1). This compound is active against MDR- TB with a minimum inhibitory concentration (MIC, i.e., the lowest concentration to completely inhibit growth of MDR-TB) of <1 microgram/mL (Agar dilution susceptibility method). In addition, this compound exhibits significant in vitro anti-HIV activity in cell culture with EC90 (concentration for 90% inhibition of virus replication) in the nM range.

A kit comprising a pharmaceutical composition according to the present invention and instructions on how to administer the composition to a patient in need represent a further aspect of the invention.
DETAILED DESCRIPTION OF THE INVENTION The following terms are used throughout the specification to describe the present invention. Unless otherwise indicated, a term used to describe the present invention shall be given its ordinary meaning as understood by those skilled in the art.
The term "compound", as used herein, unless otherwise indicated, refers to any specific chemical compound disclosed herein and includes tautomers, regioisomers and geometric isomers, as well as pharmaceutically acceptable salts thereof. Within its use in context, the term compound generally refers to a single chemically stable compound which can be administered to a patient or subject, but also may include other compounds such as tautomers, regioisomers and geometric isomers. The breadth of the term "compound" shall be construed within the context of the use of the term. It is noted that where a substituent should be present in context but is not specifically signified, it is understood that such substituent represents a hydrogen (H) atom.
The term "patient" or "subject" is used throughout the specification to describe an animal, generally a mammal and preferably a human, to whom treatment, including prophylactic treatment, with the compositions according to the present invention is provided. For treatment of those infections, conditions or disease states which are specific for a specific animal such as a human patient, the term patient refers to that specific animal.
The term "effective" is used herein, unless otherwise indicated, to describe an amount of a compound or composition or component which, in context, is used to produce or effect an intended result, whether that result relates to the treatment of a microbial, viral or other disease state, disorder or condition associated with TB or alternatively, is used to produce another compound, agent or composition. This term subsumes all other effective amount or effective concentration terms which are otherwise described in the present application.
The term "scaffold" is used to mean a dibenzyl pyridinone chemical structure. The dibenzyl group has R 1? R 2 , R 3 and R4 substituents which are as defined herein. The scaffold contains additional functionalities including a diketo-enol group and a substituted piperazine carboxamide moiety of which the X groups are as defined herein.
The term "minimum inhibitory concentration" is defined as the lowest concentration of an anti-mycobacterial compound that will inhibit completely the growth of the microorganism as visibly discerned after a delineated period.
The term "prevention" is used within context to mean "reducing the likelihood" of a condition or disease state from occurring as a consequence of administration or concurrent administration of one or more compounds or compositions according to the present invention, alone or in combination with another agent. Thus, the term prevention is used within the context of a qualitative measure and it is understood that the use of a compound according to the present invention to reduce the likelihood of an occurrence of a condition or disease state as otherwise described herein will not be absolute, but will reflect the ability of the compound to reduce the likelihood of the occurrence within a population of patients or subjects in need of such prevention.
The term "multi-drug resistant Mycobacterium tuberculosis, " which is referred to with the acronym, MDR-TB, describes tuberculosis that is resistant to isoniazid and rifampin, the two drugs that are used commonly for drug-susceptible TB and with treatment-adherent TB patients.
The term "extensively drug-resistant Mycobacterium tuberculosis, "which is referred to with the acronym, XDR-TB, describes MDR-TB that has also developed resistance to one or more of the injectable second line TB drugs (kanamycin, capreomycin or amikacin) and also to a fluoroquinolone drug. The term "extremely drug-resistant Mycobacterium tuberculosis, " referred to as XXDR-TB, is TB that is resistant to both first line and second line TB drugs.
The term "human immunodeficiency virus" or "HIV" shall be used to describe human immunodeficiency viruses 1 and 2 (HIV-1 and HIV-2). The terms "ARC" and "AIDS" refer to syndromes of the immune system caused by the human immunodeficiency virus, which are characterized by susceptibility to certain diseases and T cell counts which are depressed compared to normal counts. HIV progresses from Category 1 (Asymptomatic HIV Disease) to Category 2 (ARC), to Category 3 (AIDS), with the severity of the disease.
The term "coadministration" shall mean that at least two compounds or compositions are administered to the patient at the same time, such that effective amounts or concentrations of each of the two or more compounds may be found in the patient at a given point in time. Although compounds according to the present invention may be co-administered to a patient at the same time, the term embraces both administration of two or more agents at the same time or at different times, provided preferably that effective concentrations of coadministered compounds or compositions are found in the subject at a given time. The term
coadministration also encompasses, in certain instances, the serial administration of agents which are administered serially in a patient to produce an intended effect, regardless of the time of administration and concentration of agent found in the subject.
The term "independently" is used herein to indicate that a variable, which is independently applied, varies independently from application to application. The present invention is directed to compounds of the general molecular Formula below , including tautomer, geometric isomer, regioisomer and pharmaceutically acceptable salts or esters thereof. The groups labeled as A and B represent unsubstituted and fluoro-substituted phenyl rings, with substitutions from mono- through to tetra- substituted, involving the ortho, meta and para positions (with reference to the methylene group to which the phenyl group is bound), and combinations thereof.

When the variables involving Rj, R 2 , R 3 , and ^ occur more than once in any Formula I, the definition on each occurrence is independent of its definition at every other occurrence. Regioisomeric pyridinones, in addition to those structurally identified, are also part of this invention. There are variables and regioisomers involving the X groups on the piperazine ring. Combinations of pyridinones and R and X variables are permissible only if, in context, such combinations result in stable compounds. For the X groups, the term "aromatic," in context, refers to a substituted or unsubstituted aromatic group having a single ring (e.g., benzene) or multiple condensed rings (e.g., naphthyl, anthracenyl, phenanthryl) and this X group can be bound to the piperazine ring according to the present invention at any position on the "aromatic" ring. For substituted aromatic rings, this aromatic ring, which is bonded to the piperazine ring nitrogen, is also substituted at another position, such as at the para-position, with a nitrogen heterocyclic ring system (monocyclic or fused ring with one or more nitrogens) through its nitrogen or through one of its carbons. Substitutions of the nitrogen heterocyclic ring at other positions on the aromatic ring such as ortho- or meta- are also included in embodiments according to the present invention. In addition, other heterocyclic ring systems (in addition to nitrogen heterocycles) such as furan, thiophene, thiazole, oxazole and their corresponding fused ring systems are also contemplated for use in the present invention.

Therapeutically effective amounts of the compounds of the present invention may be administered to patients orally, including buccally, parenterally, by inhalation spray, topically, or rectally, in dosage unit formulations containing pharmaceutically-acceptable carriers, adjuvants and vehicles including nanoparticle drug delivery approaches. The term "pharmaceutically acceptable" is meant to infer that the carrier, diluent, excipient or other additive is biologically compatible with the other ingredients of the formulation and not deleterious to the patient or recipient. Pharmaceutical compositions are in pharmaceutical dosage form and may be administered in the form of orally-administrable suspensions or tablets, nasal sprays and injectible preparations (injectible aqueous or oleagenous suspensions or suppositories). This method of treatment is part of the invention. The administration approaches used (e.g., orally as solution or suspension, immediate release tablets, nasal aerosol or inhalation, injectible solutions or suspensions or rectally administered in the form of suppositories) involve techniques that are well-known in the art of pharmaceutical formulation.
The compounds of this invention can be administered orally to humans in a preferred form (such as tablets) and in an effective amount within a preferred dosage range. The specific dose level and frequency of dosage for any particular patient may be varied and will depend upon a variety of factors including compound activity, compound metabolism and duration of action, patient age, body weight, general health, sex, diet, mode and time of administration, rate of excretion, drug combination, the severity of the particular condition, and the condition of the patient undergoing therapy.
The present invention also includes therapeutically effective combinations of compounds of formula I with one or more other therapeutic agents such as other anti-TB drugs, AIDS antivirals, other antiviral agents, immunomodulators, anti-infectives, antibiotics, vaccines or other therapeutic agents. Some examples are given below. ANTI-TB DRUGS, ANTIVIRAL AGENTS, ANTI-INFECTIVES, IMMUNOMODULATORS, OPPORTUNISTIC INFECTION DRUGS, OTHER RELEVANT DRUGS TB TREATMENTS AND TB CO-INFECTIONS

Scheme 1 Chemical Synthesis: Representative Examples The following representative examples are provided to illustrate details for the preparation of the compounds of the present invention. The examples are not intended to be limitations on the scope of the present invention and they should not be so construed. Furthermore, the compounds described in the following examples are not to be viewed as forming the only set of compounds that is considered as the invention, and any combination of components of the compounds or their moieties may itself form a set. This has been addressed previously in this patent document. Those skilled in the art will readily comprehend that known variations of reaction conditions and synthetic conversions described in the following preparative procedures can be used to readily prepare these other compounds routinely.

To a chilled solution of 4-(l-(2-fluorobenzyl)-2-oxo-5-(2,4,6-trifluorobenzyl)-l,2- dihydropyridin-3-yl)-4-hydroxy-2-oxobut-3-enoic acid 1, prepared using modifications of methodologies previously described by us, J Org. Chem. 72, 8577-8579 (2007); ACS Med. Chem. Lett. 2, 877-881(2011), (103 mg, 0.224 mmol) in dimethylformamide (DMF) (1.3 mL) was added hydroxybenzotriazole (HOBT) (33 mg, 0.246 mmol), followed by l-(3- dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDCI-HC1) (47 mg, 0.246 mmol) The mixture was stirred at 0°C for 20 minutes and then 4-(naphthalen- 1 -yl)piperazin- 1 -ium chloride 3, (61 mg, 0.2463 mmol) and NaHC0 3 (21 mg, 0.246 mmol) were added. Stirring was continued for 2.5 h at 0 °C. Water was then added to precipitate the product, which was filtered and washed with additional water. This solid was dissolved in ethyl acetate (50 mL) and the solution washed with water (4 x 50 mL). The ethyl acetate extract was concentrated in vacuo and the resulting oily product was dried in vacuo to give the crude product, which was passed through a short silica gel column with chloroform as the eluting solvent. The eluent was removed and the residue was triturated with pentane to give a yellow amorphous powder (44.1 mg, 30%). UV (methanol): λ 387 nm (ε 16,349); 305 nm (ε 10,899). 1H-NMR (DMSO-d 6 , 500MHz), 5 15.00 (bs, IH), 8.21-8.12 (m, 3H), 7.95-7.91 (m, IH), 7.68-7.00 (m, 12H), 5.25 (bs, 2H), 3.88-3.74 (m, 6H), 3.74-2.82 (m, 4H).

BIOLOGY Method for Agar Dilution Drug Susceptibility Assays Against Multidrug-Resistant Mycobacterium Tuberculosis (MDR-TB) The following assays were conducted against MDR-TB following the screening guidelines of the Clinical and Laboratory Standards Institute (CLSI). Materials. The compounds were stable at room temperature and were stored at room temperature until the day of the drug susceptibility assay. Prior to screening, the compounds were solubilized in a minimum amount of DMSO. The screening was done with an isolate of MDR-TB that was resistant to both isoniazid (INH) and rifampin (R). This isolate used for the screening assays was an aliquot from a working stock culture collection that had been stored frozen at -80°C. The aliquot was allowed to thaw at room temperature and subsequently diluted in test media. The screening assays used the following positive and negative controls: (a) organism only (negative control); (b) streptomycin (anti-MDR-TB drug, positive control). Methods. The agar dilution susceptibility assay method and format were utilized for susceptibility testing. The agar medium, Middlebrook 7H10 (BD Biosciences; Sparks, MD), was prepared according to the manufacturer's guidelines and the test compounds were serially diluted two-fold to achieve a testing concentration range from 25 micrograms/mL to 0.012 micrograms/mL (total of 12 concentrations). Each concentration of compound was mixed with Middlebrook 7H10 agar, poured into sterile petri dishes (plates) and allowed to solidify. The plates were subsequently inoculated with approximately 2.0 xlO 3 CFU M. tuberculosis and incubated for 21 days at 37°C. Testing was conducted in triplicate and the MICs (minimum inhibitory concentrations) were reported as the lowest concentration (micrograms/mL) of drug that completely inhibited growth of the organism as visibly determined. Activity. Anti-MDR TB activities were observed for a significant number of compounds of this invention. The X substitutions were aromatic groups and also those in which the X aromatic group was additionally substituted with heterocyclic rings. The more active compounds had MICs against MDR-TB that were either less than one microgram/mL or significantly less than one microgram/mL.
