Chemical Structure
A-317491
- CAS No.: 475205-49-3
- Formula:C33H27NO8
- Molecular Weight:565.57
IUPAC Name: (S)-5-((3-phenoxybenzyl)(1,2,3,4-tetrahydronaphthalen-1-yl)carbamoyl)benzene-1,2,4-tricarboxylic acid
InChIKey: VQGBOYBIENNKMI-LJAQVGFWSA-N
SMILES: O=C(C1=CC(C(N(CC2=CC=CC(OC3=CC=CC=C3)=C2)[C@H]4CCCC5=C4C=CC=C5)=O)=C(C(O)=O)C=C1C(O)=O)O
Biological Activity: A-317491 is a potent, selective and non-nucleotide antagonist of P2X3 and P2X2/3 receptors, with Kis of 22, 22, 9, and 92 nM for hP2X3, rP2X3, hP2X2/3, and rP2X2/3, respectively. A-317491 is highly selective (IC50>10 μM) over other P2 receptors and other neurotransmitter receptors, ion channels, and enzymes. A-317491 reduces inflammatory and neuropathic pain by blocking P2X3 and P2X2/3 receptor-mediated calcium flux[1][2].
