Description générale

[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.

Actions biochimiques/physiologiques

Selective agonist for ETB endothelin receptors.

1. We performed radioligand binding experiments on rat cerebellar homogenates using [125I]-endothelin-1 ¿[1251]-ET-1¿ and [125I]-BQ3020 to examine the pharmacology of endothelin receptors in rat brain. Saturation experiments demonstrated a single population of binding sites with high affinity for both radioligands

[Ala1,3,11,15]-Endothelin-1, a linear analogue of endothelin-1 in which alanines replace the cystine residues, has been prepared by solid-phase synthesis in approximately 17% yield. Fmoc amino acids were coupled using an economical modified double-coupling (symmetrical anhydride followed by O-benzotriazolyl ester) procedure

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

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 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
