We hypothesized that constitutive endothelial NO synthase (eNOS) and inducible NO synthase (iNOS) have opposite effects on the regulation of endothelin and its receptors. We therefore sought to determine whether deletions of iNOS or eNOS genes in mice modulate pressor

Endothelins (ETs) are vasoactive peptides evolutionary well conserved that exert their effects through two specific receptors (ET(A) and ET(B)) widely distributed in all vertebrates. In snakes, the presence and function of endothelins and their receptors are still scarcely described. We

The signal transduction pathways of endothelin (ET)-induced vasorelaxation in rat aorta were investigated. An agonist for ETB receptors, IRL 1620, induced transient increases in cytosolic Ca++ (peak at about 10 sec) and cyclic GMP (peak at about 20 sec) accompanied

IRL-1620, a highly selective ET(B) receptor agonist, is presently in a phase I clinical trial (NCT00613691) in the United States for patients with recurrent or progressive carcinoma. The effect of acute repeated administration of IRL-1620 on the development of tachyphylaxis

Suc-[Glu9,Ala11,15]-endothelin(ET)-1(8-21), IRL 1620, is a linear ET-analog specific for the ET-isopeptide-nonselective ETB receptor. The radio-iodinated analog, [125I]IRL 1620, showed a single class of saturable binding to the ETB receptors in porcine lung membranes with a Kd of 18 pM and
