trans-3,4-Disubstituted pyrrolidines as inhibitors of the human aspartyl protease renin. Part II: prime site exploration using an oxygen linker.

Abstract:

:Inhibition of the aspartyl protease renin is considered as an efficient approach for treating hypertension. Lately, we described the discovery of a novel class of direct renin inhibitors which comprised a pyrrolidine scaffold (e.g., 2). Based on the X-ray structure of the lead compound 2 bound to renin we predicted that optimization of binding interactions to the prime site could offer an opportunity to further expand the scope of this chemotype. Pyrrolidine-based inhibitors were synthesized in which the prime site moieties are linked to the pyrrolidine core through an oxygen atom, resulting in an ether or a carbamate linker subseries. Especially the carbamate derivatives showed a pronounced increase in in vitro potency compared to 2. Here we report the structure-activity relationship of both subclasses and demonstrate blood pressure lowering effects for an advanced prototype in a hypertensive double-transgenic rat model after oral dosing.
