BQ-610
- CAS No.: 141595-53-1
- Formula:C36H44N6O6
- Molecular Weight:656.77
IUPAC Name: Na-((azepane-1-carbonyl)-L-leucyl)-1-formyl-D-tryptophyl-D-tryptophan
InChIKey: QHSRPPJQBFQWSC-OJDZSJEKSA-N
SMILES: O=C(O)[C@@H](CC1=CNC2=C1C=CC=C2)NC([C@@H](CC3=CN(C=O)C4=C3C=CC=C4)NC([C@H](CC(C)C)NC(N5CCCCCC5)=O)=O)=O
Biological Activity: BQ-610 is a selective antagonist of the endothelin A receptor (ETA receptor). BQ-610 specifically blocks the ETA receptor, competitively inhibiting the binding of endothelin-1 (ET-1) (a vasoconstrictive peptide) to the receptor, thereby blocking the effects of ET-1 such as vascular smooth muscle contraction, cell mitosis, and inhibition of hormone secretion. BQ-610 significantly alleviates cerebral vasospasm in rabbits. BQ-610 blocks the bronchial epithelial and pulmonary vascular cell proliferation caused by cigarette smoke in rat models. BQ-610 can delay the natural luteal regression in the cow's uterus. BQ-610 can be used for research on vasospasm, abnormal cell proliferation, and reproductive endocrine disorders[1][2][3].
