N-[2-(Indan-1-yl)-3-mercapto-propionyl] amino acids as highly potent inhibitors of the three vasopeptidases (NEP, ACE, ECE): In vitro and In vivo activities

Bioorg Med Chem Lett. 2002 Aug 5;12(15):2001-5. doi: 10.1016/s0960-894x(02)00248-2.

Abstract

We have previously reported the design of a lead compound 1a for the joint inhibition of neprilysin (NEP, EC 3.4.24.11), angiotensin converting enzyme (ACE, EC 3.4.15.1) and endothelin converting enzyme (ECE-1, EC 3.4.24.71), three metallopeptidases which are implicated in the regulation of fluid homeostasis and vascular tone. We report here the synthesis and biological activities of analogues derived from this lead with inhibitory potencies in the nanomolar range for the three enzymes. Compounds 8b and 15c are the most potent triple inhibitors described to date.
