With the aim of finding new renin inhibitors with improved bioavailability properties, two angiotensinogen transition state analogues 1a and 1b, containing a novel unnatural amino acid at the P(2) position, namely the (2R,3S)- and (2S,3S)-2-amino-3-(1,3-dithiolan-2-yl)-3-hydroxypropanoic acid (ADHPA), have been synthesized and tested for human renin inhibitory activity and for chemical and enzymatic
为了找到具有改善的生物利用度特性的新的肾素抑制剂,两个血管紧张素原过渡态类似物1a和1b在P(2)位置包含一个新的非天然氨基酸,即(2R,3S)-和(2S,3S)已经合成了-2-氨基-3-(1,3-二硫杂环戊-2-基)-3-羟基丙酸(ADHPA),并测试了其对人肾素的抑制活性以及化学和酶稳定性。仅化合物1a(S-异构体)具有显着的活性,该活性低于相应的组氨酸衍生物KRI-1314的活性,并且对肠胰凝乳蛋白酶的稳定性较低。
