Novel benzothiazinone derivatives of formula (I) or a pharmaceutically acceptable salt or solvate thereof have been found to be effective against Mycobacterium tuberculosis strains and may thus be useful in the treatment of tuberculosis (I) wherein, EWG (electron withdrawing group) = N02, CN, CF3, F, CI, 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; Y = a bond, or a straight or branched C1-C4 alkylene group; wherein either one of X or Y is a bond and the other is a Ci-C4-alkylene group, Z = N or C, n = 1 or 2; R1 = hydrogen, a straight or branched C1-C6 alkyl group, or a C3-C6 cycloalkyl group, which may be substituted with a group selected from F, CI, Br, I or a C1-C4 alkoxy; R2 = a phenyl group, a naphthyl group or a thienyl group, each of which may be unsubstituted or substituted with one or more substituent(s) which may be the same or different from each other, selected from the group consisting of F, CI, Br, I, CN, NO2, or a straight or branched C1-C6 alkyl or phenyl group, which may be substituted with a group selected from F, CI, Br, I, or C1-C4 alkoxy.

- Identification of antitubercular benzothiazinone compounds by ligand-based design
-
1,3-Benzothiazin-4-ones (BTZs) are a novel class of TB drug candidates with potent activity against M. tuberculosis. An in silico ligand-based model based on structure-activity data from 170 BTZ compounds was used to design a new series. Compounds were tested against a panel of mycobacterial strains and were profiled for cytotoxicity, stability, and antiproliferative effects. Several of the compounds showed improved activity against MDR-TB while retaining low toxicity with higher microsomal, metabolic, and plasma stability.
