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 μg/ml, 1.1 μM) than the standard compound 3 or 4 (3; IC50=3.7 μg/ml, 7.7 μM, 4; IC50=75 μg/ml, 155 μM). Generally, the compounds substituted at the o-position of the phenoxyacetyl group 7a, 11a, 16a and 12a showed several times higher inhibitory activity than 3.
一些来源于KNI-102的二肽类人免疫缺陷病毒(HIV)蛋白酶抑制剂被合成,这些抑制剂具有N-羧甲氧基碳酰脯氨酸-苯丙氨酸苄基酯(CPF)基团作为与gp120结合的位点。化合物11a的HIV蛋白酶抑制活性比标准化合物3或4高出7-100倍(11a;IC50=0.90 μg/ml,1.1 μM;3;IC50=3.7 μg/ml,7.7 μM;4;IC50=75 μg/ml,155 μM)。一般来说,在苯氧乙酰基团o位取代的化合物7a、11a、16a和12a显示出的抑制活性比3高出几倍。
