endothelin-1

Ac-Endothelin-1 (16-21), human acetate, the principal peptide of the endothelin family, has been shown to have a variety of biological activities in both vascular and nonvascular tissues. The C-terminal fragment, which is a highly conserved sequence in th

Endothelin 1 (swine, human) acetate is a synthetic peptide with the sequence of human and swine Endothelin 1. Endothelin 1 is a potent endogenous vasoconstrictor and acts through two types of receptors ETA and ETB.

Endothelin-1 (1-31) (Human) acetate, a potent vasoconstrictor and hypertensive agent, is produced through the selective hydrolysis of big ET-1 by chymase [1].

Endothelin 1 (swine, human), Alexa Fluor 488-labeled, is a synthetic peptide mirroring human and swine Endothelin 1, an endogenous vasoconstrictor, and is tagged with Alexa Fluor 488 for fluorescence, operating via two receptor types, ET A and ET B [1].

Endothelin-1 (1-31) (Human) is a potent vasoconstrictor and hypertensive agent, derived from the specific hydrolysis of big ET-1 by chymase [1].

[Asn18] Endothelin-1, human, a peptide, represents a predominant isoform of Endothelin, significantly contributing to the regulation of vascular function [1].

Endothelin 1 (swine, human) (TFA) is a synthetic peptide mirroring the sequence of the potent endogenous vasoconstrictor found in both human and swine Endothelin 1, operating via two receptor types, ET A and ET B [1].

Big endothelin-1 (rat 1-39), a 39-residue peptide, induces diuretic and natriuretic responses in conscious Sprague-Dawley rats and elevates blood pressure in mice [1].

Endothelin 1 (swine, human), a synthetic peptide mirroring the sequence of both human and swine Endothelin 1, functions as a robust endogenous vasoconstrictor by interacting with two receptor types, ETA and ETB.

Endothelin-1 is one of the there isoforms of endothelin (identified as ET-1, -2, -3) with varying regions of expression and binding to at least four known endothelin receptors, ETA, ETB1, ETB2 and ETC.

The big endothelins comprise residues 53-90 (human big ET-1) and 53-91 (porcine big ET-1) of the endothelin precursor (preproendothelin). Compared to the mature endothelin-1 (ET-1), both peptides show less vasoconstrictor activity in vitro, but similar pressor effects in vivo. Former CAS-number 121014-54-8.

Human Big ET-1 comprises residues 53-90 of the endothelin precursor (preproendothelin). Compared to the mature endothelin-1 (hET-1), the peptide show less vasoconstrictor activity in vitro, but similar pressor effects in vivo. Former CAS-number 121014-53-7.

Urantide acetate is a selective and competitive urotensin-II (UT) receptor antagonist (pKB = 8.3). Blocks hU-II induced contractions in thoracic aorta ex vivo. Exhibits no effect on noradrenaline or endothelin 1-induced contraction or on acetylcholine-ind

Carperitide acetate (Atrial Natriuretic Peptide (ANP) (1-28), human, porcine Acetate), a 28-amino acid hormone, is naturally produced and released by the human heart upon cardiac injury or mechanical stretch. This compound effectively inhibits the secretion of endothelin-1 in a dose-dependent manner.

Atrial Natriuretic Peptide (ANP) (1-28), rat (TFA), is the primary circulating form of ANP in rats and significantly inhibits Ang II-stimulated secretion of endothelin-1.

Sarafotoxin S6a TFA, an analogue of sarafotoxin, functions as an endothelin receptor agonist with an ET_A/ET_B selectivity profile akin to Endothelin-3. It demonstrates an EC_50 of 7.5 nM in stimulating the pig coronary artery [1].

Carperitide, a 28-amino acid hormone known as Atrial Natriuretic Peptide (ANP) (1-28), is naturally synthesized and released by the human heart in reaction to cardiac injury and mechanical stretch. This compound effectively suppresses endothelin-1 secretion in a dose-dependent manner.

[Ala1,3,11,15]-Endothelin (TFA) is a highly selective for endothelin A (ETA) and endothelin B (ETB) receptor.[Ala1,3,11,15]-Endothelin is a selective ETB endothelin receptor agonist (IC50 values are 0.33 and 2200 nM for displacing [125I]-ET-1 from ET

[Lys4] Sarafotoxin S6c, an analogue of sarafotoxin, serves as a potent, partial agonist of the endothelin receptor, inducing contraction in pig coronary artery with an effective concentration (EC 50) of 1.5 nM [1].

[Ala2] Endothelin-3, human is a linear analog of endothelin-3 (ET-3) with Ala substituting for Cys residues. ET-3, a vasoactive peptide produced by human rhabdomyosarcoma cell lines and not expressed in non-muscle-origin human sarcoma cell lines, serves as a paracrine factor by promoting endothelial cell migration [1] [2].

Adrenomedullin (13-52) is a truncated form of adrenomedullin (1-52) . It induces nitric oxide-dependent relaxation of and inhibits release of angiotensin II and endothelin-1 from isolated rat aorta. In vivo, adrenomedullin (13-52) decreases mean arterial pressure (MAP) in spontaneously and renal hypertensive rats in a dose-dependent manner. Adrenomedullin (13-52) (10-3,000 ng per animal) reverses increases in lobar arterial pressure induced by U-46619 in a dose-dependent manner in cats but has no effect on basal lobar arterial pressure or systemic arterial pressure. It also potentiates inflammatory edema and neutrophil accumulation in rats.
