چکیده
WS009 A and B, produced by Streptomyces sp. No. 89009, were found to be competitive and specific antagonists against endothelin (ET)-1 receptors in in vitro studies and also active in in vivo studies. Furthermore, WS009 A and B were specific antagonists for vascular ET-1 receptors (ETA receptors) and significantly prevented the accumulation of intracellular inositol 1,4,5-triphosphate (IP3) in endothelin treated rat aorta tissues.

متن کاملRES-701-2, -3 and -4, novel and selective endothelin type B receptor antagonists produced by Streptomyces sp. I. Taxonomy of producing strains, fermentation, isolation, and biochemical properties.
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.
متن کاملControl of Bipolaris Oryzae the Causal Agent of Rice Brown Spot Disease Via Soil Streptomyces Sp. Isolate G
Bipolaris oryzae causes rice brown spot disease which reduces rice yield with substantial global impact. Streptomycetes isolated from rice fields of Guilan Province, Iran, showed antifungal activity against the tested pathogen. From five active Streptomyces spp. isolates, isolate G showed high antagonistic activity. To determine its taxonomical identity, its colonies character...
