A new series of imidazo 2,1-b] 1,3,4]thiadiazoles 5(a-g), 6(a-g), 9(a-i) and 12(a-h) were synthesized. Among them, 23 compounds 5a, 5b, 5e, 5d, 5f, 5g, 6a, 6b, 6c, 6d, 6e, 9b, 9d, 9f, 9g, 9h, 9i, 12b, 12c, 12d, 12e, 12g, and 12h were evaluated at National Cancer Institute for single dose in vitro primary cytotoxicity assay. Compound 5b, 5e, 6c, 6d, 6e, 12c, 12d and 12e were further screened for 5-log dose molar range as they have shown prominent cell growth inhibition at 10-5 M concentration against variety of cell lines. Compound 5e shows significant inhibition against Leukemia HL-60 cell...
