Ambrisentan is a selective antagonist of ETA-receptor with Ki value of 1nM [1].

Ambrisentan is an orally active diphenyl propionic acid derivative. It is usually used to treat for pulmonary arterial hypertension. In the in vitro assay, ambrisentan shows selective affinity with ETA-receptor over ETB-receptor expressed in CHO cells. The Ki values of ETA- and ETB-receptor are 1nM and 195nM, respectively. This selectivity is much more higher for the recombinant human ET-receptors in intact cells. The Ki values of ETA- and ETB-receptor are 0.63nM and 48.7nM, respectively. As a selective antagonist of ETA-receptor, ambrisentan is preferential to non-selective receptor antagonism as it permitting maintenance of vasodilator and clearance functions specific to ETB- receptors on the endothelial cells. Moreover, ambrisentan also has possible use in the prevention of reperfusion injury and is appropriate to treat for cerebrovascular disorders [1, 2].
