Vývoj nové skupiny potenciálních antituberkulotik

Abstract

In this rigorous paper three problems were solved: a) synthesis and antimycobacterial activity of new halogenated salicylanilides substituted in position 4' with branch chain. b) synthesis and antimycobacterial activity of new halogenated 3-(4-alkylphenyl)-1,3-benzoxazine-2,4-(3H)-diones. c) influence of replacement of oxo group by thioxo group in the previously group of compounds. a) It was synthesized 8 halogenated derivatives of 4'-alkylsalicylanilides with branched alkyl chain. These compounds were evaluated in vitro on antimycobacterial activity against Mycobacterium tuberculosis, Mycobacterium kansasii and Mycobacterium avium. b) It was synthesized 7 halogenated derivatives of benzoxazinediones with branch chain by reaction of salicylanilides with methylchloroformiate. Antimycobacterial activity of synthesized compounds was evaluated against three different mycobacterial strains. The most active compound was 7- chloro-3-(4-sec-butylphenyl)-1,3-benzoxazine-2,4-(3H)-dione. c) There were synthesized the following compounds: 7-chloro-3-(4-isopropylphenyl)-4-thioxo-2H-1,3- benzoxazine-2(3H)-one, 6-bromo-3-(4-isopropylphenyl)-4-thioxo-2H-1,3-benzoxazine-2(3H)-one, 6- bromo-3-(4-sec-butylphenyl)-4-thioxo-2H-1,3-benzoxazine-2(3H)-one, 6-chloro-3-(4-sec-...
