Synthesis and evaluation of benzimidazole carbamates bearing indole moieties for antiproliferative and antitubulin activities
摘要:
A series of novel benzimidazole carbamates bearing indole moieties with sulphur or selenium atoms connecting the aromatic rings were synthesised and evaluated for their antiproliferative activities against three human cancer cell lines (SGC-7901. A-549 and HT-1080) using an MTT assay. Compounds 10a, 10b, 7a, 7b and 7f showed significant activities against these cell lines. The most potent compound in this series, 10a, was selected to investigate its antitumour mechanism. In addition, molecular docking studies suggested that compound 10a interacts very closely with the nocodazole docking pose through hydrogen bonds at the colchicine binding site of tubulin.

A practical method for the umpolung selenocyanation of aryl ketones, alkyl ketones, β-ketoesters and electron-rich arenes has been developed, affording various selenocyanates in moderate to excellent yields. This transformation proceeds by an oxidative umpolung selenocyanation through nitrogen oxides-mediated electrophilic selenocyanation process. This method is simpler, more efficient, and less costly

A new electrophilic selenocyanation reagent N-selenocyanato-dibenzenesulfonimide was readily prepared in two steps from commercially available dibenzenesulfonimide for the first time. A variety of electrophilic selenocyanato reactions of nucleophiles have been achieved using it as selenocyanato source under mild and simple conditions. Numerous SeCN-containing compounds were obtained in moderate to
