Structure–activity relationships of novel HIV-1 protease inhibitors containing the 3-amino-2-chlorobenzoyl-allophenylnorstatine structure

Abstract

A series of peptidomimetic human immunodeficiency virus (HIV) protease inhibitors containing substituted allophenylnorstatine (Apns: (2 S,3 S)-3-amino-2-hydroxy-4-phenylbutyric acid) were designed and synthesized. From the structure–activity relationship of this series of compounds, SM-309515 was found to have potent antiviral activity against wild-type and resistant HIV-1s and to possess a desirable pharmacokinetic profile in dogs.
