A series of pepstatin analogues having structural variations in the P2', P1', and P2 positions have been synthesized and tested for inhibition of porcine pepsin. The standard peptide for this study was Iva-Sta-Val-Ala-Iaa. Structural variations in the P2' and P1' positions have relatively little effect on Ki; however, small variations in the P2 position have a more dramatic effect on Ki and time-dependent
已经合成了一系列在P2′,P1′和P2位置具有结构变化的胃抑素类似物,并测试了其对猪胃蛋白酶的抑制作用。这项研究的标准肽是Iva-Sta-Val-Ala-Iaa。P2'和P1'位置的结构变化对Ki的影响相对较小;然而,P2位置的微小变化对Ki和时间依赖性抑制具有更显着的影响。还合成了一系列胃抑素片段,并测试了其对猪胃蛋白酶的抑制作用。
