Granuliberin-R and various fragment peptides were synthesized and their histaminereleasing activities were examined. The relative potencies of granuliberin-R, H-Phe-Gly-Phe-Leu-Pro-Ile-Tyr-Arg-Arg-Pro-Ala-Ser-NH2, as liberators of histamine from mast cells are very similar to those of substance P and bradykinin. Studies on the histamine-releasing activity of various fragment peptides of granuliberin-R showed that a 4-amino acid central sequence, -Ile-Tyr-Arg-Arg-, is the minimum requirement for the releasing action of this frog skin peptide.
我们合成了格拉苏木纤维素-R和各种片段肽,并研究了它们的组胺释放活性。格拉苏木纤维素-R(H-Phe-Gly-Phe-Leu-Pro-Ile-Tyr-Arg-Arg-Pro-Ala-Ser-NH2)作为肥大细胞组胺释放剂的相对效力与 P 物质和缓激肽非常相似。对颗粒纤维素-R 的各种片段肽的组胺释放活性的研究表明,4 氨基酸中心序列-Ile-Tyr-Arg-Arg-是这种蛙皮肽释放作用的最低要求。
