A practical diastereodivergent access to β-fluoropyrrolidines with two adjacent stereocenters has been demonstrated, by either enhancing or completely reversing the substrate control, in the diastereoselective fluorination of a series of diverse pyrrolidi

The small-molecule trans-3,4-disubstituted pyrrolidine 6 was identified from in silico three-dimensional (3D) pharmacophore searches based on known X-ray structures of renin-inhibitor complexes and demonstrated to be a weakly active inhibitor of the human enzyme. The unexpected binding mode of the more potent enantiomer (3S,4S)-6a in an extended conformation spanning the nonprime and S1′ pockets of the recombinant human (rh)-renin active site was elucidated by X-ray crystallography. Initial structure-activity relationship work focused on modifications of the hydrophobic diphenylamine portion positioned in S1 and extending toward the S2 pocket. Replacement with an optimized P3-P1 pharmacophore interacting to the nonsubstrate S3sp cavity eventually resulted in significantly improved in vitro potency and selectivity. The prototype analogue (3S,4S)-12a of this new class of direct renin inhibitors exerted blood pressure lowering effects in a hypertensive double-transgenic rat model after oral administration.

Novel 3-mono-, 3,4-di- and 3,4,4,-tri-substituted pyrrolidine compounds, these compounds for use in the diagnostic and therapeutic treatment of a warm-blooded animal, especially for the treatment of a disease (= disorder) that depends on inappropriate activity of renin; the use of a compound of that class for the preparation of a pharmaceutical formulation for the treatment of a disease that depends on inappropriate activity of renin; the use of a compound of that class in the treatment of a disease that depends on inappropriate activity of renin; pharmaceutical formulations comprising a said substituted pyrrolidine compound, and/or a method of treatment comprising administering a said substituted pyrrolidine compound, a method for the manufacture of said substituted pyrrolidine compounds, and novel inter-mediates and partial steps for their synthesis are described. The substituted pyrrolidine compounds are especially of the formula (I), wherein the substituents are as described in the specificacion.
