In search of novel anticancer agents, a series of N-methyl colchiceinamide derivatives (7a–7i) containing 1,3,4-thiadiazole moieties were synthesized, and their structures were confirmed by spectral analysis. Cytotoxicity of these compounds was evaluated by MTT assay in vitro against four human tumor cell lines, i.e. A2780, A549, BEL7402, and MCF-7. The results indicated that most of the derivatives...
To search for more potent antitumor agent, a series of novel nitric oxide-donating colchicine (Col) derivatives (6a–f, 8a and b) were synthesized by coupling nitrates with N-methyl colchiceinamide. Their cytotoxicity against four human cancer cell lines in vitro were evaluated by MTT assay. It was found that many of the derivatives displayed significant activity, particularly, compounds 6c, 8a and...
