Synonym(s): AT2 receptor agonist C21 hydrochloride
- CAS No.: 1947313-60-1
- Formula:C23H30ClN3O4S2
- Molecular Weight:512.09
InChIKey: BIIVOXDZWDUHOO-UHFFFAOYSA-N
SMILES: O=C(NS(=O)(C1=C(C2=CC=C(CN3C=NC=C3)C=C2)C=C(CC(C)C)S1)=O)OCCCC.Cl
Biological Activity:
Buloxibutid (AT2 receptor agonist C21) hydrochloride is an orally active, selective angiotensin II type 2 receptor (AT2R) agonist, with a Ki value of 0.4 nM for porcine AT2R. Buloxibutid hydrochloride exerts vasodilatory, anti-inflammatory, antifibrotic (promoting the expression of collagenase MMP-13) and tissue repair effects mainly by activating the NO/cGMP pathway, inhibiting the pro-proliferative MAPK signaling, and suppressing the pro-fibrotic TGF-β/Smad pathway and inflammatory NF-κB pathway. Buloxibutid hydrochloride can be used in research related to idiopathic pulmonary fibrosis, hypertension, systemic sclerosis and other conditions[1][2][3][4].
