Dapson in heterocyclic chemistry part VI: synthesis and molecular docking of some novel sulfonebiscompounds of expected anticancer activity.

To discover new bioactive lead compounds for medicinal purposes, herein, sulfone biscompounds bearing dihydrothiazoles (3-9, 14, 15), acrylamide (11), thiazolidinones (12, 13, 20), thiophenes (16, 17) and benzothiophene (19) were prepared and tested for their anticancer activity. The structures of the products were confirmed from elemental analysis as well as spectral data. All the synthesized compounds showed remarkable anticancer activity against human breast cancer cell line especially, compound (3) with IC50 value 23.02 µM which was better than that of Doxorubicin by three folds. In order to elucidate the mechanism of action of their cytotoxic activity molecular docking on the active sites of farnesyl transferase and arginine methyl transferase was performed for all synthesized compounds and good results were obtained.
