合成了一系列含有 4-氨基-3-羟基-5-苯基戊酸所有可能异构体的抑制剂,并测试了其对 HIV-1 蛋白酶的抑制作用。将叔丁氧羰基保护的氨基酸的 (3S,4S) 异构体掺入 Glu-Phe 序列中,产生了有效的 HIV-1 蛋白酶抑制剂 (Ki= 63 nM)。该抑制剂的效力比含有 4-氨基-3-羟基-5-苯基戊酸其他异构体的抑制剂至少强 47 倍,表明 (3S,4S) 异构体是与 HIV-1 蛋白酶结合的优选异构体。
A series of inhibitors containing all possible isomers of 4-amino-3-hydroxy-5-phenylpentanoic acid was synthesized and tested for inhibition of HIV-1 protease. Incorporation of the (3S,4S) isomer of the t-butyloxycarbonyl protected amino acid into the sequence Glu-Phe resulted in a potent inhibitor of HIV-1 protease (Ki= 63 nM). This inhibitor is at least 47- times more potent than the inhibitors containing other isomers of 4-amino-3-hydroxy-5-phenylpentanoic acid, indicating that the (3S,4S) isomer is the preferred isomer for binding to HIV-1 protease.
