Biphenyl/diphenyl ether renin inhibitors: Filling the S1 pocket of renin via the S3 pocket
摘要:
Structure-based design led to the discovery of a novel class of renin inhibitors in which an unprecedented phenyl ring filling the S1 site is attached to the phenyl ring filling the S3 pocket. Optimization for several parameters including potency in the presence of human plasma, selectivity against CYP3A4 inhibition and improved rat oral bioavailability led to the identification of 8d which demonstrated antihypertensive efficacy in a transgenic rat model of human hypertension.

nickel-catalyzed direct ortho-thiolation of N-benzoyl α-amino acidderivatives. This novel strategy showed wide generality, functional tolerance, and high regioselectivity. In addition, dipeptidederivatives were also compatible with this transformation system, providing a potential protocol for the direct modification of peptide derivatives.

established in the peptides Boc-Aib-Gpn-Aib-OMe and Boc-Gpn-Aib-NHMe, respectively. Selective line broadening of NH resonances and the observation of medium range NH(i) <--> NH(i+2) NOEs established the presence of conformational heterogeneity for the tetrapeptide in CDCl3 solution. The NMR results are consistent with the limited population of the continuous C12 helix conformation. Lengthening of the
