Endothelin-1 (ET-1) has been linked to a number of conditions including pulmonary arterial hypertension (PAH). ET-1 acts via 2 receptors, ETA and ETB.

Two receptors for endothelin, ETA and ETB, have been found in the human lung, and according to recent studies a non-ETA receptor seems to mediate the contraction of large sized human bronchi. E.M.

ORIGINAL ARTICLE Distortion of KB estimates of endothelin-1 ETA and ETB receptor antagonists in pulmonary arteries: Possible role of an endothelin-1 clearance mechanism James A. Angus1 | Richard J. A. Hughes1 | Christine E. Wright1 Endothelin-1 may therefore have an autocrine or paracrine role in the control of ADH release. Endothelin-1 stimulates atrial natriuretic peptide (ANP) production in vitro and in vivo (Haynes and Webb, 1993a). ANP inhibits generation of endothelin-1 and also attenuates its effects.

The goal of this study was to characterize the role of Endothelin (ET) type B receptors (ETB) on vascular function in healthy and diseased conditions and demonstrate how it affects the pharmacological activity of ET receptor antagonists (ERAs).

The efficacy of bosentan, a mixed ETA-ETB endothelin receptor antagonist, in protecting the myocardium from ischemia-reperfusion injury and oxidative stres …. Endothelin-1 has been shown to be associated with greater myocardial ischemia and reperfusion injury in which oxidative stress plays a key role. The efficacy of bosentan, a mixed ETA-ETB

The ETA and ETB receptors are members of the heptahelical G-protein-coupled receptor superfamily, range from 45 to 50 kDa in size (Levin 1995). In systemic and pulmonary vessels, ETA receptors are primarily located on the vascular smooth muscle cells Indeed, to prevent endothelin-induced re- ins have potent biological effects, eg, vasoconstriction, sponses, a combined ETA/ETB antagonist such as bosen- vasodilation, and potentiation of the effect of other tan is required, particularly at lower concentrations of vasoconstrictors and mitogenesis.1-4,6,2728 Endothelin endothelin (which are more likely to be achieved in also has been implicated endothelin-1 (ET) for the ET and ET receptors with of A B K i 4.7 nM and 95 nM in human SMC, respectively. Bioactivity: BQ-123 is an ETA endothelin receptor antagonist (Ki values are 1.4 and 1500 nM at ETA and ETB receptors respectively) . 1) Reduces ischemia-induced ventricular arrhythmias in … Endothelins (ETs) are a family of novel regulatory peptides and various lines of evidence suggest an important role for ETs in regulating pulmonary function.

The ability of ET-1 to promote collagen gel contraction was blocked by an endothelin receptor A/endothelin receptor B (ETA/ETB) receptor antagonist, bosentan Macitentan (ACT 064992) is an orally active, non-peptide, dual ETA/ETB ( endothelin) receptor antagonist with IC50 of 0.5 nM/391 nM.

Together with ET-1, ETA, and ETB receptor expression on endothelial cells of ingrown new blood vessels, this points to an involvement of ET-1 and its receptors in corneal angiogenesis. As potent ETA and ETB receptors are available, the endothelin system may represent an additional target for corneal antiangiogenic therapy. PMID: 16160501
