- Design, synthesis and antitubercular evaluation of benzothiazinones containing an oximido or amino nitrogen heterocycle moiety
-
A series of 8-nitro-6-(trifluoromethyl)-1,3-benzothiazin-4-ones (BTZs) bearing an oximido or amino nitrogen heterocycle moiety through modifications at the C-2 position of BTZ043 and BPTZ169 were designed and synthesized as new antitubercular agents. Many of the target compounds demonstrate excellent in vitro activity (MIC: ?1) against the drug susceptive H37Rv strain and two clinically isolated multidrug-resistant Mycobacterium tuberculosis (MTB) strains. Compound 10a displays acceptable safety, aqueous solubility and pharmacokinetic properties, opening up a new possibility for further development.

- BENZOTHIAZINONE DERIVATIVES AS ANTI -TUBERCULOSIS AGENTS
-
Novel benzothiazinone derivatives of formula (I) or pharmaceutically acceptable salts or solvates thereof have been found to be effective against Mycobacterium tuberculosis strains and may thus be useful in the treatment of tuberculosis: wherein EWG (electron withdrawing group) = NO2, CN, CF3, F, Cl, Br, OCF3, OH, OR, OCHF2, COOR, wherein R is hydrogen or a straight or branched C1-C4 alkyl group, X = a bond or a straight or branched C1-C4 alkylene group which may be substituted with a group selected from F, Cl, Br, I or C1-C4 alkoxy; Y = hydrogen, a straight or branched C1-C4 alkyl group, OH or OR, wherein R is hydrogen or a straight or branched C1-C4 alkyl group; n = 0, 1 or 2; R1, R2 = hydrogen or substituent (s) which may be the same or different from each other and are selected from the group consisting of D, F, Cl, Br, CF3, a straight or branched C1-C4 alkyl group, a phenyl group, OR, SR, NR3R4, wherein R, R3, R4 may be the same or different from each other and are hydrogen or a straight or branched C1-C4 alkyl group or a phenyl group.
