The design and synthesis of renin inhibitors that incorporate the novel dipeptide isostere (4S,5S)-5-amino-6-cyclohexyl-4-hydroxyhex-1-ene-2-carboxylic acid as a transition-state analogue are described. Titanium-promoted condensation of dilithiated N-alkylmethacrylamides with protected amino aldehydes results in efficient preparation of protected dipeptide analogues 7 and 8. Incorporation of 7 into
描述了肾素抑制剂的设计和合成,该抑制剂结合了新型二肽等排物(4S,5S)-5-氨基-6-环己基-4-羟基己基-1-烯-2-羧酸作为过渡态类似物。钛促进的二锂化N-烷基甲基丙烯酰胺与受保护的氨基醛缩合,可有效制备受保护的二肽类似物7和8。将7掺入血管紧张素原的部分序列可提供有效的人肾素体外抑制剂。对不饱和酰胺部分的进一步化学处理允许研究P1'和P2'位点的结构-活性关系。介绍了合成,立体化学测定和体外肾素抑制的详细信息。
