N-Aryl-benzimidazolones as novel small molecule HSP90 inhibitors
摘要:
We describe the development of a novel series of N-aryl-benzimidazolone HSP90 inhibitors ( 9) targeting the N-terminal ATP-ase site. SAR development was influenced by structure-based design based around Xray structures of ligand bound HSP90 complexes. Lead compounds exhibited high binding affinities, ATPase inhibition and cellular client protein degradation. (C) 2010 Elsevier Ltd. All rights reserved.
Compounds which bind to and inhibit the activity of HSP90, compositions containing the compounds and methods of treating diseases that are caused or exascerbated by overexpression of HSP90 are disclosed.

environmentally friendly. A new and convenient protocol is presented for the synthesis of 1-arylbenzimidazol-2-ones by a one-pot reaction of N-aryl-2-nitrosoanilines using solid carbon dioxide as a source of the key carbonyl moiety. The metal-free process is carried out under mild conditions and is compatible with a variety of substituents. The atom economy of the synthesis of the starting nitrosoanilines
