N-Adamantane-substituted tetrapeptide amides and the pharmacologically acceptable salts thereof are disclosed herein. These compounds are analogs of enkephalin wherein the methionine or leucine of position 5 has been substituted by an adamantyl amide and the glycine of position 2 has been substituted by various amino acid residues. Optionally the tyrosine of position 1 and the phenylalanine of position 4 may be substituted by various amino acid residues. These compounds exhibit agonist activity at opiate receptor sites and are useful as analgesics.
本文披露了N-戊二醛基取代的四肽酰胺及其药理学上可接受的盐。这些化合物是镇痛肽恩啡啶的类似物,其中第5位的蛋氨酸或亮氨酸被戊二醛基酰胺取代,第2位的甘氨酸被各种氨基酸残基取代。可选地,第1位的酪氨酸和第4位的苯丙氨酸可以被各种氨基酸残基取代。这些化合物在阿片受体位点表现出激动剂活性,并可用作镇痛剂。
