Description
IC50 & Target
|
ETB |
In Vitro
IRL-1620 is the most potent and specific ligand for the ETB receptor (KiETA/ KiETB=120,000) as judged by the Ki values for ETA (19 μM) and ETB (16 PM) receptors[1]. IRL-1620 is 60 times more selective for the ETB receptor than ET-3 (KiETA/ KiETB=1,900)[1]. IRL-1620 (1-100 nM) induces contractions of the guinea pig trachea. The effective concentration that produces 30 % of 60 mM KCI-induced contraction is estimated to be 28 nM for IRL 1620[1]. IRL-1620 (1-100 nM) increases cytosolic Ca2+ in the vascular endothelium ([Ca]E) with little effect on resting muscle tone, and relaxes the norepinephrine-stimulated tone with an increase in [Ca]E, in rat aorta[1].
