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.

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

A linear peptide analog of endothelin (ET)-1, [Ala1,3,11,15]ET-1 (4AlaET-1), and its truncated peptide analogs were synthesized to study the structural requirements of ET-1 for the recognition of ETs-nonselective ETB receptors. ET-1 exhibited sub-nanomolar binding to two distinct ET receptor subtypes
