A series of 1,3,4-oxadiazole-2-thione and 1,2,4-triazole-5-thione derivatives have been successfully synthesized and studied for their antitumor activity. These compounds were prepared from carboxylic acids and chiral aminoacid esters. The prepared compounds were evaluated for their cytotoxicity against cancer in vitro using hydroxyurea (HU) as positive control. A fair number of compounds were found to have significant antitumor activity. To study the molecular basis of interaction and affinity of binding of the target molecules, all the compounds were docked into the ATPase domain of TP-II and tubulin using Schrodinger.
