Some dipeptide-type human immunodeficiency virus (HIV) protease inhibitors derived from KNI-102, with a N-carbomethoxycarbonylprolyl-phenylalanine benzyl ester (CPF) moiety as a binding site to gp120, were synthesized. Compounds 11a showed 7--100 times higher HIV protease-inhibitory activity (11a; IC50 = 0.90 microgram/ml, 1.1 microM) than the standard compound 3 or 4 (3; IC50 = 3.7 micrograms/ml, 7.7 microM, 4; IC50 = 75 micrograms/ml, 155 microM). Generally, the compounds substituted at the o-position of the phenoxyacetyl group 7a, 11a, 16a and 21a showed several times higher inhibitory activity than 3.

HIV-1 protease inhibitors containing allophenylnorstatine [Apns; (2S,3S)-3-amino-2-hydroxy-4-phenylbutyric acid]-Pro (syn diastereomer) as a transition-state mimic were established to be potent and highly selective. Z-Asn-Apns-Pro-NHBut (KNI-102) is the only tripeptide exhibiting substantial anti-HIV activity and may be of minimum size for potent, selective inhibition of HIV protease. Ready availability due to its simple chemical structure and stability should make it valuable for studies of the development of metabolically stable anti-AIDS drugs.
