The action of the aspartyl protease renin is the rate-limiting initial step of the renin-angiotensin-aldosterone system. Therefore, renin is a particularly promising target for blood pressure as well as onset and progression of cardiovascular and renal diseases. New pyrimidine derivatives 5–14 were designed in an attempt to enhance the renin inhibitory activity of compound 3 identified by our previous fragment-based drug design approach. Introduction of a basic amine essential for interaction with the two aspartic acids in the catalytic site and optimization of the S1/S3 binding elements including an induced-fit structural change of Leu114 (‘Leu-in’ to ‘Leu-out’) by a rational structure-based drug design approach led to the discovery of N-(piperidin-3-yl)pyrimidine-5-carboxamide 14, a 65,000-fold more potent renin inhibitor than compound 3. Surprisingly, this remarkable enhancement in the inhibitory activity of compound 14 has been achieved by the overall addition of only seven heavy atoms to compound 3. Compound 14 demonstrated excellent selectivity over other aspartyl proteases and moderate oral bioavailability in rats.
