Renin inhibitors. Dipeptide analogs of angiotensinogen utilizing a structurally modified phenylalanine residue to impart proteolytic stability
摘要:
A series of renin inhibitors have been prepared and evaluated for their susceptibility to cleavage by the serine protease chymotrypsin. The compounds were designed by consideration of the structural requirements in the active-site region of renin and chymotrypsin. By systematic alteration of the P3 phenylalanine residue, compounds with varying degrees of renin inhibitory potency and chymotrypsin susceptibility were obtained. Selected analogues from this group were examined in vivo for both their hypotensive effects and metabolic patterns.

Enantiodivergent Deprotonation/Acylation of α-Amino Nitriles
title reaction of enantioenriched α‐ureidonitriles was found to proceed in a highly enantiodivergent manner despite the intermediacy of stereolabile α‐nitrile metallocarbanions. Enantiodivergence is dependent upon the base used. For the less basic hexamethyldisilazides (HMDS), deprotonation in which a metal (M) cation is precomplexed with an electrophile is proposed. LDA=lithiumdiisopropylamide.
