Partial retro-inverso modification of a single peptide bond was applied to pGlu-Phe-Phe-Gly-Leu-Met-NH2 (I), a C-terminal hexapeptide analogue of the neuropeptide substance P. Two analogues with reversed peptide bonds, between the pGlu-Phe and Phe-Gly residues, were prepared, purified and characterized. The analogue gpGlu-(RS)-mPhe-Phe-Gly-Leu-Met-NH2 (II) was devoid of either agonistic or antagonistic
单肽键的部分逆向逆向修饰应用于pGlu-Phe-Phe-Gly-Leu-Met-NH2(I),这是神经肽物质P的C端六肽类似物。两个具有反向肽键的类似物之间制备,纯化和鉴定pGlu-Phe和Phe-Gly残基。类似物gpGlu-(RS)-mPhe-Phe-Gly-Leu-Met-NH2(II)没有激动或拮抗活性。发现第二种伪肽类似物,即pGlu-Phe-gPhe-mGly-Leu-Met-NH2(III),是完全的激动剂,在豚鼠回肠测定中具有I的22%的效价。
