New Groups of Potential Antituberculotics: 3-(4-Ethoxythiocarbonylphenyl)-2H-benzoxazin-2,4(3H)-dithiones and 3-(4-Ethoxythiocarbonylphenyl)-4-thioxy-2H-benzoxazin-2,4(3H)-ones

In connection with the search for new antituberculotics, the present authors prepared a group ofderivatives of 3-(4-ethoxythiocarbonylphenyl)-2H-benzoxazin-2,4(3H)-dithione and 3-(4-ethoxythiocarbonylphenyl)-4-thioxy-2H-benzoxazin-2,4(3H)-one. The modifications of substituents were carriedout on the benzoxazine ring. The study was based on the present authors' previous assumptionthat the substitution of the oxo group for the thioxo group was connected with an increase inantimycobacterial activity. The prepared substances were evaluated by the activity against Mycobacteriumtuberculosis, Mycobacterium kansasii, and Mycobacterium avium. However, it was concludedthat there was no assumed increase in antimycobacterial activity in the groups of3-(4-ethoxythiocarbonylphenyl)-4-thioxy-2H-benzoxazin-2,4(3H)-one and 3-(4-ethoxythiocarbonylphenyl)-2H-benzoxazin-2,4(3H)-dithione derivatives.
