Recently, trans-disubstituted oxo-aryl-piperidines have been identified as small molecule nonpeptide renin inhibitors for the modulation of hypertension. Herein, we report on the discovery and preparation of a new class of novel cis-disubstituted amino-aryl-piperidines as a mixture of enantiomers that are potent in vitro renin inhibitors and also, possess in vivo antihypertensive activity in a double transgenic mouse model.
