General description

[Ala1,3,11,15]-Endothelin 1 is a linear endothelin (ET)-1 analogue, and acts as an ETB receptor agonist. ET-1 is a peptide that acts as both, a vasodilator and a vasoconstrictor. It is a ligand for ET receptor, which is of two types, ETA and ETB. ETB receptor is found in the vascular endothelial cells of cardiovascular tissues.

Application

[Ala1,3,11,15]-Endothelin 1 may be used to assess the effects of endothelin-1 and [Ala1,3,11,15]-endothelin 1 produced by ETA and ETB receptors, in the presence of BQ-123, in anaesthetized rat.

Biochem/physiol Actions

Selective agonist for ETB endothelin receptors.

The physiologic role of endothelin-1 (ET-1) and its receptors in regulating fetal pulmonary vascular tone is unknown. We therefore investigated the role of ET-1 and its receptors in the regulation of fetal pulmonary vascular tone using BQ 123 (an ETa

1. The aim of the present study was to examine the contractile responses evoked by the recently characterized vasoactive peptide endothelin-1 (ET-1) and by two of its structural analogues, [Ala3,11]ET-1 and [Ala1,15]ET-1 in endothelium-denuded rat isolated aorta, and also to

1. The effects of endothelin-1 and of three analogues in which alanyl residues had been substituted in place of cysteinyl residues were studied in the rat, isolated, Krebs-Henseleit-perfused mesenteric bed and the in situ, blood-perfused, mesenteric and hindquarters circulations of

An in vitro model of endothelial cell injury was used to investigate the role of endothelins and related peptides in endothelial repair. Endothelin-3 (10-100 nM) enhanced wound repair over an 18 h period by promoting proliferation, an effect not inhibited

1. The influence of BQ-123 (a selective ETA-receptor antagonist) on the haemodynamic response elicited by endothelin-1 (ET-1) and [Ala1,3,11,15]ET-1 (a selective ETB-receptor agonist) was studied in anaesthetized rats instrumented with ultrasonic Doppler flow probes on the carotid, coeliac, mesenteric, renal
