-Val-Leu-OR, with statine [3S,4S)-4-amino-3-hydroxy-6-methylheptanoic acid, Sta) or with Sta-Phe. The best inhibitor, Boc-Phe-Leu-Ala-(S,S)-Sta-Val-Leu-OMe, inhibited cathepsin D with a Ki value of 1.1 nM. In general, the more effective inhibitors were consistent with the proposal that statine functions as a replacement for a dipeptidyl unit. Thirty-five known pepstatin analogues also were evaluated
合成了五种新的组织蛋白酶D抑制剂并将其作为牛组织蛋白酶D的抑制剂进行测试。这些化合物是通过替换良好的组织蛋白酶D底物Boc-Phe-Leu-Ala-Phe-Phe-Val-Leu的Phe-Phe二肽基单元而衍生的。 -OR,与他汀[3S,4S)-4-氨基-3-羟基-6-甲基庚酸(Sta)或与Sta-Phe。最好的抑制剂Boc-Phe-Leu-Ala-(S,S)-Sta-Val-Leu-OMe抑制组织蛋白酶D,Ki值为1.1 nM。通常,更有效的抑制剂与他汀类药物作为二肽基单位的替代品的提议是一致的。还评估了三十五个已知的胃抑素类似物作为组织蛋白酶D抑制剂。P4和P3'位置的取代基对于最大限度抑制这种天冬氨酸蛋白酶很重要,
