A series of new 3-amino-5-sulfanyl-1,2,4-triazole and 2-amino-5-sulfanyl-1,3,4-thiadiazole derivatives have been synthesized and their cytotoxicities were evaluated on a panel of human cancer cell lines (BxPC-3, H1975, SKOV-3, A875, HCT116, etc.). The best one (compound 5m) exhibited activities with...
