ECE-1 and NEP with IC50 values of 14 nM and 2 microM, respectively. Similarly, (S)-[[1-[(2-biphenyl-4-ylethyl)carbamoyl]-4-(2-fluorophenyl)but-3- yny l]amino]methyl]phosphonic acid (56), an arylacetylene amino phosphonate amide, had IC50's of 33 nM and 6.5 microM for ECE-1 and NEP, respectively. Slight modification of the aryl moiety was found to have dramatic effects on ECE-1/NEP selectivity. The 2-fluoro
内皮素-1是迄今为止发现的最有效的肽血管收缩剂。该肽的翻译后加工的最后一步是内皮素转化酶-1(ECE-1)对其前体的转化,该酶是一种金属蛋白酶,与中性内肽酶24.11(NEP)表现出很高的氨基酸序列同一性,尤其是在催化中心。已经制备了一系列有效的和选择性的含芳基乙炔的ECE-1抑制剂。(S,S)-3-环己基-2-[[5-(2,4-二氟苯基)-2-[(膦酰基甲基)氨基]戊-4-炔基]氨基]丙酸(47),芳基乙炔基氨基发现膦酸二肽可抑制ECE-1和NEP,IC50值分别为14 nM和2 microM。类似地,(S)-[[[[[1-[(2-联苯-4-基乙基)氨基甲酰基] -4-(2-氟苯基)丁-3-yny]氨基]甲基]膦酸(56),芳基乙炔氨基膦酸酯酰胺,对ECE-1和NEP的IC50分别为33 nM和6.5 microM。发现芳基部分的轻微修饰对ECE-1 / NEP选择性具有显着影响。2-氟
