Renin-Angiotensin System Studies

Introduction of the 2,2-dimethyl-4-phenylpiperazin-5-one scaffold into the P(3)-P(1) portion of the (2S,4S,5S)-5-amino-6-dialkylamino-4-hydroxy-2-isopropylhexanamide backbone dramatically increased the renin inhibitory activity without using the interaction to the S(3)(sp) pocket. Compound 31 exhibited >10,000-fold selectivity over other human proteases, and 18.5% oral bioavailability in monkey.
