A series of 3,4,5-trisubstituted aminothiophenes were designed, synthesized, and evaluated for their p53-MDM2 binding inhibitory potency and anti-proliferation activities against A549 and PC3 tumor cell lines. Fourteen compounds had appreciably improved MDM2 binding affinities than lead compound MCL0527 (3) and a few compounds showed comparable activities to that of Nutlin-3. Meanwhile, most of the 3,4,5-trisubstituted aminothiophenes displayed better or equivalent anti-proliferation activities against wild-type p53 cell line A549 compared to that of Nutlin-3. Over ten compounds exhibited desirable selective profiles of p53 status. Particularly, compounds 9, 16 and 18 displayed 22-, 6- and 22-fold selectivity of p53 status, respectively, much better than that of Nutlin-3 (fourfold). (C) 2013 Elsevier Ltd. All rights reserved.
