1. WS009 A and B, new endothelin receptor antagonists isolated from Streptomyces sp. no. 89009. II. Biological characterization and pharmacological characterization of WS009 A and B
S Miyata, M Hashimoto, K Fujie, M Shouho, K Sogabe, S Kiyoto, M Okuhara, M Kohsaka J Antibiot (Tokyo). 1992 Jul;45(7):1041-6. doi: 10.7164/antibiotics.45.1041.
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.
2. WS009 A and B, new endothelin receptor antagonists isolated from Streptomyces sp. no. 89009. I. Taxonomy, fermentation, isolation, physico-chemical properties and biological activities
S Miyata, N Ohhata, H Murai, Y Masui, M Ezaki, S Takase, M Nishikawa, S Kiyoto, M Okuhara, M Kohsaka J Antibiot (Tokyo). 1992 Jul;45(7):1029-40. doi: 10.7164/antibiotics.45.1029.
WS009 A and B novel endothelin receptor antagonists, have been isolated from the fermentation broth of Streptomyces sp. No. 89009. These antagonists were purified from the culture filtrate followed by Diaion SP-207, DEAE Toyopearl column chromatography and HPLC. WS009 A and B showed selective activity in an endothelin receptor binding assay with IC50 of 5.8 x 10(-6) M and 6.7 x 10(-7) M, respectively. On the basis of spectroscopic and chemical evidence, the structures of WS009 A and B have been established as 1 and 3, and are highly hydroxylated benz[a]anthraquinone chromophores.
