3R)‐DAHHA‐Leu‐Pro‐OH, 4], analogue of the N‐terminal tripeptide of probestin, has been synthesized, and tested as inhibitor of AP‐B, Leu‐AP, AP‐M, and enkephalin‐degrading APs, and as analgesic. In order to establish structure‐activity relationships the dipeptide (2S,3R)‐DAHHA‐Pro‐OH (5) and the tripeptide (2S, 3R)‐DAHHA‐Ala‐Pro‐OH (6) were also prepared. Compounds 4 and 6 were potent and selective inhibitors of enkephalin‐degrading
(2S, 3R) -3,7-diamino-2-hydroxy-heptanoyl-Leu-Pro-OH [(2S, 3R) -DAHHA-Leu-Pro-OH, 4],探针蛋白 N 端三肽的类似物, 已被合成,并被测试为 AP-B、Leu-AP、AP-M 和脑啡肽降解 AP 的抑制剂,以及作为镇痛剂。为了建立结构-活性关系,还制备了二肽(2S,3R)-DAHHA-Pro-OH(5)和三肽(2S,3R)-DAHHA-Ala-Pro-OH(6)。化合物 4 和 6 是脑啡肽降解 AP 的有效和选择性抑制剂,并显示出延长的镇痛作用。
