  New cholesterol esterase inhibitors based on rhodanine and thiazolidinedione scaffolds

  摘要：

  We present a new class of inhibitors of pancreatic cholesterol esterase (CEase) based on 'priviledged' 5-benzylidenerhodanine and 5-benzylidene-2,4-thiazolidinedione structural scaffolds. The lead structures (5-benzylidenerhodanine 4a and 5-benzylidene-2,4-thiazolidinedione 4b) were identified in an in-house screening and these inhibited CEase with some selectivity over another serine hydrolase, acetylcholinesterase (AChE) (4a, CEase IC50 = 1.76 mu M vs AChE IC50 = 5.14 mu M and 4b, CEase IC50 = 5.89 mu M vs AChE IC50 > 100 mu M). A small library of analogs (5a-10a) containing a core amino acid in place of the glycerol group of the lead structures, was prepared to explore other potential binding interaction with CEase. These analogs inhibited CEase with IC50 values ranging from 1.44 to 85 mu M, with the majority exhibiting some selectivity for CEase versus AChE. The most potent compound of the library (10a) had 17-fold selectivity over AChE. We also report molecular docking (with CEase) and detailed kinetic analysis on the amino acid analogs to further understand the associated structure-activity relationships. (C) 2011 Elsevier Ltd.
