描述 | A-317491 exhibits high efficacy and selectivity as a non-nucleotide P2X3 and P2X2/3 receptor blocker, presenting Kis of 22, 22, 9, and 92 nM against hP2X3, rP2X3, hP2X2/3, and rP2X2/3, respectively. Its selective action (IC50>10 μM) spans beyond other P2 receptors and a range of neurotransmitter receptors, ion channels, and enzymes, mitigating inflammatory and neuropathic pain by obstructing P2X3 and P2X2/3 receptor-mediated calcium movement . |
Animal study | Given as a single subcutaneous injection ranging from 0.1 to 30 mg/kg, it systematically alleviates inflammatory mechanical sensitivity in rats .Administered intravenously at doses between 3 and 30 mg/kg, A-317491 displays a half-life of 7.38 hours, a clearance rate of 1.83 L/h/kg, and a distribution volume of 0.17 L/kg . |
