A series of 2-(naphthalen-1-yl)-methyl-6-arylimidazo[2,1-b][1,3,4]thiadiazole derivatives was prepared and studied for cytotoxicity against murine leukemia L1210, human cervix carcinoma HeLa, and human T-lymphocyte CEM cell lines. The preliminary study showed that compounds 5g, 6g, 7a-c, 7e, and 8e were more potent among the tested compounds. The pharmacokinetic properties of all compounds were then investigated with FAF-Drugs, a tool for prediction of ADME and toxicity. Finally, in order to support in vitro studies, molecular docking studies were performed by using AutoDock Vina with a Lamarckian genetic algorithm to determine whether or not the synthesized compounds could be used as inhibitors for the protein structure 1m17 (EGFR). The docking scores of many compounds were found to be higher than [6,7-bis(2-methoxy-ethoxy)quinazoline-4-yl]-(3-ethynyl phenyl)amine, an inhibitor of the 1m17 EGFR receptor. Among the selected compounds 7b, 7c, 7e, 7f, 7g, and 8g showed better stability in the molecular dynamics simulation study.

A lead compound with the (1,3,4-thiadiazol-2-yl)-acrylamide scaffold was discovered to have significant cytotoxicity on several tumor cell lines in an in-house cell-based screening. A total of 60 derivative compounds were then synthesized and tested in a CCK-8 cell viability assay. Some of them exhibited improved cytotoxic activities. The most potent compounds had IC50 values of 1–5 μM on two acute leukemia tumor cell lines, i.e. RS4;11 and HL-60. Flow cytometry analysis of several active compounds and detection of caspase activation indicated that they induced caspase-dependent apoptosis. It was also encouraging to observe that these compounds did not have obvious cytotoxicity on normal cells, i.e. IC50 > 50 μM on HEK-293T cells. Although the molecular targets of this class of compound are yet to be revealed, our current results suggest that this class of compound represents a new possibility for developing drug candidates against acute leukemia.
