Abstract
Three kinds of 1,5-benzothiazepines containing 1,2,3-triazole, 3-(1H-1,2,3-triazolyl)-4-aryl-2,5-dihydro-1,5-benzothiazepines (5a~5f), 3-(2H-1,2,3-triazolyl)-4-aryl-2,3-dihydro-1,5-benzothiazepines (6a~6f) and 3-(1H-1,2,3-triazolyl)-4aryl-2,3,4,5-tetrahydro-1,5-benzothiazepines (7a~7f), were designed and synthesized. The synthesis conditions of intermediates and target products were studied. Two by-products were separated and their structures were determined. The antifungal activity test of the target products showed that compounds 5a~5f exhibited high inhibitory effects against fungi especially for Cryptococcus neoformans. The preliminary study on the structure-activity relationship of antifungal activity reveled that 1H-1,2,3-triazolyl and C=C double bond were the key function groups in the antifungal activity of 5a~5f.
