Resumen
Aim: Bozepinib is a potent and selective anticancer compound which chemical structure is made up of a benzofused seven-membered ring and a purine moiety. We previously demonstrated that the purine fragment does not exert antiproliferative effect per se. Methodology: A series of 1-(benzenesulfonyl)-4,1-benzoxazepine derivatives were synthesized in order to study the influence of the benzofused seven-membered ring in the biological activity of bozepinib by means of antiproliferative, cell cycle and apoptosis studies. Results & conclusion: Our results show that the methyleneoxy enamine sulfonyl function is essential in the antitumor activity of the structures and thus, it is a scaffold suitable for further modification with a view to obtain more potent antitumor compounds.
