  Potent and selective small molecule NS3 serine protease inhibitors of Hepatitis C virus with dichlorocyclopropylproline as P2 residue

  摘要：

  Starting from a pentapeptide Hepatitis C virus NS3 protease inhibitor, a number of alpha-ketoamide inhibitors based on novel dichlorocyclopropylproline P2 core were synthesized and investigated for their HCV NS3 serine protease activity. The key intermediate 3,4-dichlorocyclopropylproline was obtained through a dichloro carbene insertion to 3,4-dehydroproline. The size of the molecules was reduced significantly through a series of truncations of the initial pentapeptide. By varying P1 side chain in length and size, potency and selectivity were improved. A variety of aliphatic carbamate and urea capping groups were examined. In general, compounds with urea cappings were more potent and selective than their carbamate counterparts. The most potent compound was a tert-butyl urea analog. Variations at P3 position were also investigated. Among the three residues incorporated, tert-leucine was clearly superior, leading to compounds that had excellent enzyme potency and selectivity. The most potent compound achieved cell-based replicon assay EC50 of 40 nM. The most promising compound of all had excellent potency in both enzyme (K-i* = 9 nM) and replicon assays (EC50 = 100 nM). Its bioavailabilities were above 10% in all three animal species (rats, monkeys, and dogs). It has provided a lead for future investigations. (c) 2007 Elsevier Ltd. All rights reserved.
