  Inhibition of the severe acute respiratory syndrome 3CL protease by peptidomimetic α,β-unsaturated esters

  摘要：

  The proteolytic processing of polyproteins by the 3CL protease of severe acute respiratory syndrome coronavirus is essential for the viral propagation. A series of tripeptide alpha,beta-unsaturated esters and ketomethylene isosteres, including AG7088, are synthesized and assayed to target the 3CL protease. Though AG7088 is inactive (IC50 > 100 mu M), the ketomethylene isosteres and tripeptide alpha,beta-unsaturated esters containing both P1 and P2 phenylalanine residues show modest inhibitory activity (IC50 = 11-39 mu M). The Phe-Phe dipeptide inhibitors 18a-e are designed on the basis of computer modeling of the enzyme-inhibitor complex. The most potent inhibitor 18c with an inhibition constant of 0.52 mu M is obtained by condensation of the Phe-Phe dipeptide alpha,beta-unsaturated ester with 4-(dimethylamino)cinnamic acid. The cell-based assays also indicate that 18c is a nontoxic anti-SARS agent with an EC50 value of 0.18 mu M. (c) 2005 Elsevier Ltd. All rights reserved.
