Potent and selective small-molecule human urotensin-II antagonists with improved pharmacokinetic profiles
摘要:
Lead compound 1 was successfully redesigned to provide compounds with improved pharmacokinetic profiles for this series of human urotensin-II antagonists. Replacement of the 2-pyrrolidinylmethyl-3-phenyl-piperidine core of 1 with a substituted N-methyl-2-(1-pyrrolidinyl) ethanamine core as in compound 7 resulted in compounds with improved oral bioavailability in rats. The relationship between stereochemistry and selectivity for hUT over the kappa-opioid receptor was also explored. (C) 2008 Elsevier Ltd. All rights reserved.
Development of potent and selective small-molecule human Urotensin-II antagonists
摘要:
This work describes the development of potent and selective human Urotensin-II receptor antagonists starting from lead compound 1, (3,4-dichlorophenyl) methyl{2-oxo-2-[3-phenyl-2-(1-pyrrolidinylmethyl)1-piperidinyl]ethyl}amine. Several problems relating to oral bioavailability, cytochrome P450 inhibition, and off-target activity at the kappa opioid receptor and cardiac sodium channel were addressed during lead development. hUT binding affinity relative to compound 1 was improved by more than 40-fold in some analogs, and a structural modi. cation was identified which significantly attenuated both off-target activities.
