Peptides that contain difluorostatine and difluorostatone residues have been shown to be potent inhibitors of the aspartyl protease renin. The readily hydrated fluoro ketone is proposed to mimic the tetrahedral intermediate that forms during the enzyme-catalyzed hydrolysis of a peptidic bond. It is suggested that the sp3-hybridized ketal acts as a transition-state analogue renin inhibitor. The fluoro
已显示含有二氟他汀和二氟他酮残基的肽是天冬氨酰蛋白酶肾素的有效抑制剂。提议将易水合的氟代酮模拟在肽催化的酶催化水解过程中形成的四面体中间体。建议将sp3杂化的缩酮用作过渡态类似物肾素抑制剂。氟代酮显示出比相应的非氟代酮更有效的抑制剂,后者是伪底物。P1位点上更多的亲脂性侧链可以增强二氟他汀类似物的抑制能力,但这在二氟他酮系列中无法得到证实。另外,对于含二氟他酮的肽已经显示出高的肾素特异性。
