摘要:
Novel diallyl and dibenzylthiosemicarbazones were prepared by three-step reactions. The compounds were tested for their in vitro activity against Mycobacterium tuberculosis H37Rv (MTB) and multi-drug-resistant Mycobacterium tuberculosis (MDR-TB). Most of the compounds showed excellent activity toward MDR-TB. Among the thirty compounds (4,5a-o) tested N,N-dibenzyl-2-((5-nitrofuran-2-yl)methylene)hydrazinecarbothioamide (5g) was found to be the most potent compound MICs of 0.55 and 0.12 mu M against MTB and MDR-TB.
