endothelin-2

Endothelin-2 (49-69), human (Human endothelin-2), is a 21-amino-acid vasoactive peptide that binds to G-protein-coupled receptors ET-RA and ET-RB.

Endothelin-2 (49-69), human (TFA), is a 21-amino acid vasoactive peptide that binds to ET-RA and ET-RB receptors.

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

[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].

BQ-3020 ammonium, a selective endothelin receptor (ET B receptor) agonist, demonstrates inhibition of [125 I] ET-1 binding to ET B receptors with an IC50 of 0.2 nM and induces vasoconstriction in rabbit pulmonary arteries. Additionally, it promotes relaxation of the pig urinary bladder neck, rendering it useful for research into cardiovascular diseases [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.
