A series of 3-[3-[4-(substituted)-1-cyclicamine]propyl]thio-5-substituted[1,2,4]triazoles (8a-m) and 2-[3-[4-(substituted)-1-cyclicamine]propyl]-5-(substituted)-2,4-dihydro-3H[1,2,4]triazole-3-thiones (9a-h) were synthesized with good yields starting from corresponding carboxylic acids using two different methods. The cytotoxicity studies of these derivatives were studied against five different human cancer cell lines. Six compounds had shown good anticancer activity. The triazole derivatives, 9d, 8j, and 8i were most potent particularly against U937 and HL-60 cells. The cytotoxic potency of the compounds varied between the cell lines suggesting that a structural property of these compounds as possible determinant of their biological activity.
