(+)-Thiocolchicine (2b) was prepared from (+/-)-colchicine (1) in a five-step reaction sequence that included chromatographic separation of appropriate camphanylated diastereomers. Acid hydrolysis of the (+)-diastereomer, followed by acetylation, yielded the desired product 2b. (+)-Thiocolchicine has 15-fold lower inhibitory activity against

During a cellular screening of thiocolchicine analogs, thiocolchicine dimers resulted particularly active in cisplatin-resistant A2780-CIS cells. In order to discover by which mechanism(s) thiocolchicine dimers overcame cisplatin resistance, p53, p21waf1 and MLH1 were assessed by Western blot. Results pointed out
