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].

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

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.

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.

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

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].

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 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.

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-induced relaxation. Behav

IRL-1620 acetate is an effective and selective agonist of Endothelin B receptor (ETB) with a Ki of 16 pM which is more selective than ETA with a Ki of 19 μM.

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.

BQ-123 is a selective endothelin A receptor (ETA) antagonist with IC50 of 7.3 nM. Phase 2.

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].

[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].

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.

Atrial Natriuretic Peptide (ANP) (1-28), human, porcine Acetate is an atrial natriuretic peptide (ANP) hormone secreted by atrial myocytes that is capable of acting as an natriuretic peptide receptor-A(NPR-A) agonist, used in the treatment of acute decompensated heart failure (ADHF). By binding to specific receptors on the surface of the kidney, blood vessel, and heart cells, Carperitide causes an increase in cyclic guanosine monophosphate (cGMP) levels and induces vasodilatation, diuresis, and sodium excretion, which in turn reduces the heart's workload.

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.
