Twenty-two novel 1,3,4-thiadiazole derivatives were synthesized using different aromatic acids as starting materials, followed by cyclization, coupling and deprotection reaction. The structures of all the target compounds were identified by means of IH nuclear magnetic resonance（NMR）, laC NMR and high resolution mass spectrometer（HRMS）. Further biological evaluations were performed for chronic myelogenous leukemia cell and breast cancer cell. The results suggest that most of the target compounds exhibit potent anti-proliferative activities. Especially, compound 5b shows better antiproliferative activities against MDA-MB-231 and K562 cell lines compared with gossypol.
