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.
已发现式(I)的新型苯并噻嗪酮衍生物或其药学上可接受的盐或溶液对结核分枝杆菌菌株有效,因此可用于治疗结核病:
其中
EWG(取电子基团)=NO2 CN、CF3、F、Cl、Br、OCF3、OH、OR、OCHF2、COOR,其中 R 是氢或直链或支链 C1-C4 烷基、
X = 键或可被选自 F、Cl、Br、I 或 C1-C4 烷氧基的基团取代的直链或支链 C1-C4 亚烷基;
Y = 氢、直链或支链 C1-C4 烷基、OH 或 OR,其中 R 是氢或直链或支链 C1-C4 烷基;
n = 0、1 或 2;
R1、R2 = 氢或取代基,这些取代基可以相同或不同,选自由 D、F、Cl、Br、CF3、直链或支链 C1-C4 烷基、苯基、OR、SR、NR3R4 组成的组,其中 R、R3、R4 可以相同或不同,并且是氢或直链或支链 C1-C4 烷基或苯基。
