A series of eleven (E)-2-benzothiazole hydrazones were synthesized and evaluated for their in vitro anticancer activities against three neoplastic cancer cells: HL-60 (leukemia), MDAMB-435 (breast) and HCT-8 (colon). Two of them, 3e and 3f, showed good cytotoxicity activity for HL-60. The results also demonstrated that compound 3f seems to be selective to HL-60 cell line, appearing as a good prototype for an antileukemia lead molecule.
