Amberlite IR-120H catalyzed MCR: Design, synthesis and crystal structure analysis of 1,8-dioxodecahydroacridines as potential inhibitors of sirtuins
摘要:
A rapid, inexpensive and high yielding method has been developed for the synthesis of 1,8-dioxodecahydroacridines using Amberlite IR-120H as a reusable catalyst under open air. These compounds were designed as potential inhibitors of sirtuins and prepared via the MCR of 5,5-dimethyl-1,3-cyclohexanedione, (hetero)aryl aldehydes and (hetero)aromatic amines under mild conditions. Further structure elaboration of a representative compound was performed via Pd catalyzed C-C bond forming reactions. The crystal structure analysis and H-bonding patterns along with in vitro inhibitory activity against yeast Sir2 of the same compound is presented. Docking studies indicated that the compound interacts well with the yeast Sir2. (C) 2013 Elsevier Ltd. All rights reserved.
