The emergence of drug-resistant HIV from a widespread antiviral chemotherapy targeting HIV protease in the past decades is unavoidable and provides a challenge to develop alternative inhibitors. We synthesized a series of allophenylnorstatine-based peptidomimetics with various P-3, P-2, and P-2' moieties. The derivatives with P-2 tetrahydrofur-anylglycine (Thfg) were found to be potent against wild type HIV-1 protease and the virus, leading to a highly potent compound 21f (KNI-1657) against lopinavir/ritonavir- or darunavir-resistant strains. Co-crystal structures of 21f and the wild-type protease revealed numerous key hydrogen bonding interactions with Thfg. These results suggest that the strategy to design allophenylnorstatine-based peptidomimetics combined with Thfg residue would be promising for generating candidates to overcome multidrug resistance.
