SB 247083

Catalog No.: A60239
Endothelin-A Receptor Antagonist
SB 247083 is a selective and competitive antagonist of the endothelin-A receptor, exhibiting a Ki value of 0.41 nM. It displays a significantly lower affinity for the endothelin-B receptor with a Ki of 467 nM. SB 247083 effectively inhibits ET-1-induced contractions in rat aorta, with a Kb of 3.5 nM. This reagent is valuable for research focusing on cardiovascular diseases and their underlying mechanisms.
