Design, synthesis and biological evaluation of 1,4-benzodiazepine-2,5-dione-based HDAC inhibitors
摘要:
New histone deacetylase inhibitors have been synthesized and evaluated for their activity against non-small lung cancer cell line H661. These compounds have been designed with diversely substituted 1,4-benzodiazepine-2,5-dione moieties as cyclic peptide mimic cap structures, and a hydroxamate side chain. Biological evaluations demonstrated that benzodiazepine-based HDACi bearing an aromatic substituent at the N1 position exhibited promising anti proliferative and HDAC-inhibitory activities.

The melanocortin system consists of five seven-transmembrane spanning G-protein coupled receptors (MC1-5) that are stimulated by endogenous agonists and antagonized by the only two known endogenous antagonists of GPCRs, agouti and agouti-related protein (AGRP). These receptors have been associated with many physiological functions, including the involvement of the MC4R in feeding behavior and energy homeostasis, making this system an attractive target for the treatment of obesity. Small-molecule mimetics of endogenous ligands may result in the development of compounds with properties more suitable for use as therapeutic agents. The research presented herein involves the synthesis and analysis of 12 melanocortin receptor agonists using the 1,4-benzodiazepine-2,5-dione template and is the first report of these derivatives as melanocortin receptor agonists. Structure-activity relationship studies using this privileged structure, template has resulted in molecules with molecular weights around 400 that possess nanomolar agonist potency at the melanocortin receptors examined in this study.
