title: Docking studies, synthesis, characterization of some novel oxazine substituted 9-anilinoacridine derivatives and evaluation for their antioxidant and anticancer activities as topoisomerase II inhibitors.
abstract: A series of 9-anilinoacridines substituted with oxazine derivatives were synthesized to evaluate their antioxidant and anticancer activity against Daltons Lymphoma Ascites (DLA) cell growth by in vitro method. It was revealed that these conjugates exhibited significant antioxidant and anticancer activity (inhibition of DLA cell proliferation). Among these agents, compounds 5a, 5h, 5i, 5j were the most cytotoxic with CTC(50) value of 140-250 μg/mL. The docking studies of the synthesized compounds were performed towards the key Topoisomerase II (1QZR) by using Schrodinger Maestro 9.2 version. The oxazine substituted 9-anilinoacridine derivatives 5a, 5h, 5i, 5j have significant anticancer activity as topoisomerase II inhibitors.
