چکیده انگلیسی
Benzo[3,4]azepino[1,2-b]isoquinolinones were designed and developed as constraint forms of 3-arylisquinolines with an aim to inhibit topoisomerase I (topo I). Ring closing metathesis (RCM) of 3-arylisoquinolines with suitable diene moiety provided seven membered azepine rings of benzoazepinoisoquinolinones. Spectral analyses of these heterocyclic compounds demonstrated that the methylene protons of the azepine rings are nonequivalent. The shielding environment experienced by these geminal hydrogens differs unusually by 2.21Â ppm. As expected, benzoazepinoisoquinolinones displayed potent cytotoxicity. However, cytotoxic effects of the compounds were not related to topo I inhibition which is explained by non-planar conformation of the rigid compounds incapable of intercalating between DNA base pairs. In contrast, flexible 3-arylisoquinoline 8d attains active conformation at drug target site to exhibit topo I inhibition identical to cytotoxic alkaloid, camptothecin (CPT).
