Abstract
Due to the unusual structure and chemical composition of the mycobacterial cell wall, effective tuberculosis (TB) treatment is difficult, making many antibiotics ineffective and hindering the entry of drugs. With approximately 33% of infection, TB is still the second most deadly infectious disease worldwide. The reasons for this are drug-resistant TB (multidrug resistant and extensively drug resistant), persistent infection (latent TB) and synergism of TB with HIV; furthermore no new chemical entity has emerged in last 40 years. New data available from the recently sequenced genome of the mycobacterium and the application of methods of modern drug design promise much for the fight against this disease. In this review, we present an introduction to TB, followed by an overview of new heterocyclic anti-tubercular moieties published during the last decade.

Abstract
Three new series of quinoline-4-yl-1,2,3-triazoles carrying amides, sulphonamides and amidopiperazines were synthesized through multi-step reactions. The required intermediate, [1-(6-methoxy-2-methylquinolin-4-yl)-1H-1,2,3-triazol-4-yl]methanol (2) was prepared by treating 4-azido-6-methoxy-2-methylquinoline (1) with propargyl alcohol. Three different series of compounds were synthesized from this intermediate. All the newly synthesized compounds were characterized by spectral and elemental analyses. The structure of 2 was confirmed by X-ray crystallographic study. Further, the title compounds were evaluated for their in vitro anti-bacterial activity against five different bacterial strains and antimycobacterial activity against Mycobacterium tuberculosis H37Rv, Mycobacterium smegmatis (ATCC 19420) and Mycobacterium fortuitum (ATCC 19542). Title compounds, 6a, 6d, 6i, 6j, 7e, 10a and 10i were found to be active against Mycobacterium tuberculosis H37Rv strain and could be lead molecules of interest.

Abstract
Fourteen 5-nitro-2,6-dioxohexahydro-4-pyrimidinecarboxamides (3a-n) were synthesized and evaluated for their in vitro activity against Mycobacterium tuberculosis H37Rv (MTB), multidrug-resistant Mycobacterium tuberculosis (MDR-TB), and Mycobacterium smegmatis (MC(2)), as well as their cytotoxicity and MTB isocitrate lyase (ICL) inhibition activity. 1-Cyclopropyl-6-fluoro-8-methoxy-7-(3-methyl)-4-[(5-nitro-2,6-dioxohexahydro-4-pyrimidinyl)carbonyl]piperazino-4-oxo-1,4-dihydro-3-quinolinecarboxylic acid (3n) was found to be the most active compound in vitro with MICs of < 0.17 and 0.17 μM against log-phase MTB and MDR-TB, respectively. Some compounds showed 20-45% inhibition against MTB ICL at 10 μM.

Abstract
Twenty four novel 2-[3-(4-bromo-2-fluorobenzyl)-4-oxo-3,4-dihydro-1-phthalazinyl]acetic acid amides were synthesized from phthalic anhydride and were subjected to in vitro and in vivo evaluation against log- and starved phase of mycobacterial species and Mycobacterium tuberculosis isocitrate lyase enzyme inhibition studies. Among the compounds screened, 2-(2-(4-bromo-2-fluorobenzyl)-1,2-dihydro-1-oxophthalazin-4-yl)-N-(2,6-dimethylphenyl)acetamide (5j) inhibited all eight mycobacterial species with MIC's ranging from 0.08 to 5.05 microm and was non-toxic to Vero cells till 126.43 microm. Four compounds were tested against starved culture of Mycobacterium tuberculosis and they inhibited with MIC's ranging from 3.78 to 23.2 microm. Some compounds showed 40-66% inhibition against Mycobacterium tuberculosis isocitrate lyase enzyme at 10 microm. The docking studies also confirmed the binding potential of the compounds at the isocitrate lyase active site. In the in vivo animal model, 5j reduced the mycobacterial load in lung and spleen tissues with 1.38 and 2.9-log10 protections, respectively, at 25 mg/kg body weight dose.

Abstract
A series of 26 new quinoline derivatives carrying active pharmacophores has been synthesized and evaluated for their in vitro antituberculosis activity against Mycobacterium tuberculosis H37Rv (MTB), Mycobacterium smegmatis (MC(2)), and Mycobacterium fortuitum following the broth micro dilution assay method. Compounds 13e, 13i, 13k, 14a, 14c, 14i, and 14k exhibited significant minimum inhibition concentrations, when compared with first line drugs isoniazid (INH) and rifampicin (RIF) and could be ideally suited for further modifications to obtain more efficacious compounds in the fight against multi-drug resistant tuberculosis.

Abstract
Twenty two novel 2,10-dihydro-4aH-chromeno[3,2-c]pyridin-3-yl derivatives were synthesized by reacting 3-formyl chromone, (sub)-2-amino pyridines, N1-(prop-2-ynyl)arylamides in the presence of indium triflate. The compounds were evaluated their preliminary in-vitro and in-vivo activity against Mycobacterium tuberculosis H37Rv (MTB) and multi-drug resistant M. tuberculosis (MDR-TB). Among them N-[(4aS)-2-(3-methyl-2-pyridinyl)-10-oxo-2,10-dihydro-4aH-chromeno[3,2-c]pyridin-3-yl]methyl-4-ethylbenzenecarboxamide 4d was found to be the most active compound in-vitro with MIC's of 0.22 and 0.07 microg/mL against MTB and MDR-TB respectively. In the in-vivo animal model 4d decreased the bacterial load in lung and spleen tissues with 1.11 and 2.94-log10 protections respectively at 25 mg/kg body weight dose.
