Abstract

RES-701-2, -3 and -4, novel cyclic peptide endothelin antagonists, were isolated from the culture broths of Streptomyces sp. RE-701 and RE-896, RES-701s selectively inhibited the ET-1 binding to endothelin type B receptor (ETB receptor) with IC50 values ranging from 5 to 20 nM. Taxonomy of the producing strains, fermentation, isolation and biochemical properties of RES-701s are described.

摘要

RES-701-2、-3和-4是新型环肽内皮素拮抗剂,从链霉菌属RE-701和RE-896的培养液中分离得到。RES-701s选择性抑制内皮素-1与B型内皮素受体(ETB受体)的结合,IC50值在5至20 nM之间。本文描述了产生菌的分类学、RES-701s的发酵、分离及生化特性。
