Functionally, 27and 29 were the two most efficacious compounds from this study, producing sustained inhibition of ECE-1 activity in rats, as measured by their ability to block the hypertensive effects induced by big ET-1. This profile was similar to that of a potent ET(A)/ET(B) dual receptor antagonist, SB 209670. Due to their favorable in vitro and in vivo profiles, 27 (CGS 34043) and 29 (CGS 35066) constitute
人类内皮素转化酶-1(ECE-1)的有效和选择性非肽类抑制剂已被设计为体内内皮素(ET-1)生产的潜在调节剂。由于其独特的结构特征和在体内的长效作用,双重ECE-1和中性肽链内切酶24.11(NEP)抑制剂CGS 26303被选为进一步优化效能和选择性的诱人先导。用构象受限的3-二苯并呋喃基取代CGS 26303的P(1)'联苯取代基导致更有效和更具选择性的ECE-1抑制剂,如四唑27。这种P(1)'修饰的显着效果首次允许膦酰基甲基羧酸(如29)显示出强效(IC(50)= 22 nM)和选择性(相对NEP的104倍)ECE-1抑制作用。开发了新的α-氨基酸(S)-3-二苯并呋喃-3-基丙氨酸中间体的化学合成方法,并设计了改进的程序来生成取代的α-氨基烷基膦酸以支持各种类似物的生产。尽管通过添加P(1)侧链偶尔可以实现内在ECE-1抑制能力的额外提高,但这些化合物(例如43a)在大ET-1加
