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:
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;
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 C1-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, Cl, 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, Cl, 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, Cl, Br, I, or C1-C4 alkoxy.
化合物(I)的新型苯并噻唑酮衍生物或其药学上可接受的盐或溶剂已被发现对结核分枝杆菌菌株有效,并因此可能在结核病治疗中有用:其中EWG(电子提取基团)= NO2、CN、CF3、F、Cl、Br、OCF3、OH、OR、OCHF2、COOR,其中R为氢,或直链或支链C1-C4烷基;X为键,或直链或支链C1-C4亚烷基;Y = 键,或直链或支链C1-C4亚烷基;其中X或Y中的一个为键,另一个为C1-C4亚烷基,Z = N或C,n = 1或2;R1 = 氢,直链或支链C1-C6烷基,或C3-C6环烷基,可用F、Cl、Br、I或C1-C4烷氧基中选择的基团取代;R2 = 苯基,萘基或噻吩基,每个基团可以未取代或取代一个或多个取代基(s),其可相同或不同于来自F、Cl、Br、I、CN、NO2或直链或支链C1-C6烷基或苯基的基团,可用F、Cl、Br、I或C1-C4烷氧基中选择的基团取代。
