Structure-activity relationships of a series of 2-amino-4-thiazole-containing renin inhibitors
摘要:
A series of renin inhibitors was synthesized that contained a 2-amino-4-thiazolyl moiety at the P2 position. These derivatives are potent inhibitors of monkey renin in vitro and are selective in that they only weakly inhibit the closely related aspartic proteinase, bovine cathepsin D. Four compounds exhibited oral blood pressure lowering activity in high-renin normotensive monkeys. One of these compounds, 22 (PD 134672), was selected for further evaluation in renal hypertensive monkeys, on the basis of its superior efficacy and duration of action in the in vitro assays and the normotensive primate model.

for renin over cathepsin D by correct modification at the P2' and P1-P1' sites. Variations at the P4 site have been utilized to lower the log P values of these renininhibitors while maintaining high potency. Compound 42, which exhibited an IC50 of 3.70 nM, log P of 2.3, and showed high specificity for renin, was selected for further studies. It was found to be very stable under neutral, acidic, and

To understand the differences in the binding specificities within the asparticproteinase family of enzymes, we have carried out studies to determine the inhibition constants of a set of related compounds with various members of the human enzyme family. The inhibition constants (Ki values) were determined by competitive inhibition of the hydrolysis of chromogenic octapeptide substrates in the pH range
