endothelin 3

Endothelin-3, human, mouse, rabbit, rat TFA is a 21-amino acid vasoactive peptide that specifically interacts with G-protein-linked transmembrane receptors [ET-RA and ET-RB].

[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].

Endothelin-3 (human, mouse, rabbit, rat) is a cyclic 21-amino acid peptide, acting as an endogenous neuropeptide and potent vasoconstrictor.

[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

[Ala1,3,11,15]-Endothelin (53-63) (TFA) is a selective ET B agonist with IC50 values from 0.33 nM to 0.61 nM, indicating a high affinity for ET B receptors, and is used in vasoconstriction research.

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].

Atrial natriuretic peptide (3-28) (human) (ANP (3-28) (human)), a peptide hormone produced by the atrial myocardium, critically regulates blood pressure, fluid balance, and electrolyte homeostasis [1] [2].

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.
