  Novel, potent and orally bioavailable indolizidinone-derived inhibitors of the hepatitis C virus NS3 protease

  摘要：

  A novel, potent, and orally bioavailable class of product-like inhibitors of the HCV NS3 protease was discovered by constraining the P2-P3 amide bond and the P3 hydrocarbon substituent to the proteasebound conformation. This preorganization was accomplished by incorporation of the P2-P3 amide into a six-membered ring attached to the P2-proline 5-position. isothermal calorimetric characterization of the role of hydrocarbon substitution of this six-membered ring, upon binding the HCV NS3 protease, was found to be exclusively entropic in nature. The synthesis, preliminary SAR and pharmacokinetic profiling of this compact, indolizidinone-derived scaffold are described. (C) 2011 Elsevier Ltd. All rights reserved.
