Highly active potential antituberculotics: 3-(4-alkylphenyl)-4-thioxo-2H-1,3-benzoxazine-2(3H)-ones and 3-(4-alkylphenyl)-2H-1,3-benzoxazine-2,4(3H)-dithiones substituted in ring-B by halogen

Abstrakt

The replacement of the oxo group bythioxo group of 3-(4-alkylphenyl)-2H-1,3-benzoxazine-2,4(3H)-diones often led to an improvement in the antimycobacterial activity against M. tuberculosis
