Synthesis and structure-activity relationships of 2-substituted D-tryptophan-containing peptidic endothelin receptor antagonists: Importance of the C-2 substituent of the D-tryptophan residue for endothelin A and B receptor subtype selectivity
Continuing studies on modifications of potent cyclic pentapeptide endothelin (ET) receptor antagonists, represented by BQ-123, and potent linear tripeptide derivative ET receptor antagonists, represented by BQ-788, are described herein. The introduction o
