Inhibitors of hepatitis C virus NS3.4A protease 1. Non-charged tetrapeptide variants

Bioorg Med Chem Lett. 2003 Nov 17;13(22):4059-63. doi: 10.1016/j.bmcl.2003.08.050.

Abstract

Tetrapeptide-based peptidomimetic compounds have been shown to effectively inhibit the hepatitis C virus NS3.4A protease without the need of a charged functionality. An aldehyde is used as a prototype reversible electrophilic warhead. The SAR of the P1 and P2 inhibitor positions is discussed.
