Scientific background
Atrasentan (A-127722) is a synthetic compound that acts as a potent and selective antagonist of endothelin A (ET-A) receptor. Atrasentan is highly selective towards ET-A receptor, exhibiting 1000-fold selectivity over ET-B receptors1. It inhibits endothelin-1 radioligand binding with an IC50 value of 0.36 nM and endothelin-1-stimulated phosphoinositol hydrolysis with an IC50 of 0.16 nM1.ET-A receptors are predominantly detected in peripheral tissues, especially in vascular smooth muscle tissues where they mediate vasoconstriction. They are also expressed in several regions of the brain. The ET-A receptor has high affinity for endothelin-1 and endothelin-2 and relatively low affinity for endothelin-3, while the ET-B receptor has high affinity for all endothelin isopeptides2.
