The cyclic peptide RES-701-1, originally isolated from the culture broth of Streptomyces sp. RE-701, shows high selectivity for ET-B receptors. RES-701-1 inhibited ET-1 binding to ET-B receptors with an IC₅₀ value of 10 nM and blocked ET-B receptor-mediated responses. It may provide a powerful tool for understanding the physiological roles of the ET-B receptor.
