β-Amino acid substitutions and structure-based CoMFA modeling of hepatitis C virus NS3 protease inhibitors
摘要:
In an effort to develop a new type of HCV NS3 peptidomimetic inhibitor, a series of tripeptide inhibitors incorporating a mix of alpha- and beta-amino acids has been synthesized. To understand the structural implications of beta-amino acid substitution, the P-1, P-2, and P-3 positions of a potent tripeptide scaffold were scanned and combined with carboxylic acid and acyl sulfonamide C-terminal groups. Inhibition was evaluated and revealed that the structural changes resulted in a loss in potency compared with the a- peptide analogues. However, several compounds exhibited mu M potency. Inhibition data were compared with modeled ligand-protein binding poses to understand how changes in ligand structure affected inhibition potency. The P-3 position seemed to be the least sensitive position for beta-amino acid substitution. Moreover, the importance of a proper oxyanion hole interaction for good potency was suggested by both inhibition data and molecular modeling. To gain further insight into the structural requirements for potent inhibitors, a three-dimensional quantitative structure-activity relationship (3D- QSAR) model has been constructed using comparative molecular field analysis (CoMFA). The most predictive CoMFA model has q(2) = 0.48 and r(pred)(2) = 0.68. (C) 2008 Elsevier Ltd. All rights reserved.
