产品详情
A-317491 sodium salt hydrate 是一种有效,选择性和非核苷酸的 P2X3 和 P2X2/3 受体的拮抗剂,对 hP2X3,rP2X3,hP2X2/3 和 rP2X2/3 的 Ki 值分别为 22,22,9 和 92 nM。A-317491 sodium salt hydrate 对其他 P2 受体和神经递质受体,离子通道以及酶具有高度选择性 (IC50>10 μM)。A-317491 sodium salt hydrate 通过阻断 P2X3 和 P2X2/3 受体介导的钙通量减轻炎性和神经性疼痛。
生物活性
A-317491 sodium salt hydrate is a potent, selective and non-nucleotide antagonist of P2X 3 and P2X 2/3 receptors, with K i s of 22, 22, 9, and 92 nM for hP2X 3 , rP2X 3 , hP2X 2/3 , and rP2X 2/3 , respectively. A-317491 sodium salt hydrate is highly selective (IC50>10 μM) over other P2 receptors and other neurotransmitter receptors, ion channels, and enzymes. A-317491 sodium salt hydrate reduces inflammatory and neuropathic pain by blocking P2X 3 and P2X 2/3 receptor-mediated calcium flux.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
