A Novel Class of Orally Active Non-Peptide Bradykinin B<sub>2</sub> Receptor Antagonists. 4. Discovery of Novel Frameworks Mimicking the Active Conformation
a molecular modeling study reported in part1 of this series, we designed and synthesized a series of sterically constrained analogues by replacing the N-methylamide group with cis-amide-like rigid moieties. We discovered several bioisosteres and chemically proved that the N-methylamide moiety adopts the cis-amide form in the active conformation. Extensive chemical modification led to the identification
