Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	5.000mg/ml (8.84mM)	Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
Clear solution	5% DMSO 1 95% Corn oil この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	0.300mg/ml (0.53mM)	Taking the 1 mL working solution as an example, add 50 μL of 6 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	A-317491 is a novel potent and selective non-nucleotide antagonist of P2X₃ and P2X_2/3 receptors with Ki values of 22 nM and 9 nM for human P2X₃ and P2X_2/3 receptors.
in vitro	A-317491 potently blocks recombinant human and rat P2X3 and P2X2/3 receptor-mediated calcium flux (Ki = 22-92 nM) and is highly selective (IC50 >10 μM) over other P2 receptors and other neurotransmitter receptors, ion channels, and enzymes. This compound does not undergo any detectable metabolism (oxidation or glucuronidation) in in vitro assays using human and rat liver microsomes^[1].
in vivo	A-317491 dose-dependently (ED50 = 30 μmol/kg s.c.) reduces complete Freund's adjuvant-induced thermal hyperalgesia in the rat. This compound is most potent (ED50 = 10-15 μmol/kg s.c.) in attenuating both thermal hyperalgesia and mechanical allodynia after chronic nerve constriction injury. Although active in chronic pain models, this chemical is ineffective (ED50 >100 μmol/kg s.c.) in reducing nociception in animal models of acute pain, postoperative pain, and visceral pain. Preliminary pharmacokinetic studies in rats indicate that 10 μmol/kg of this compound had high (≈80%) systemic bioavailability after s.c. dosing (estimated plasma concentration = 15 μg/ml, >99% protein bound) and a half-life in plasma of 11 h^[1]. It is effective in reducing pain associated behavior in several animal models of inflammatory and neuropathic pain when administered systemically. This compound does not significantly penetrate into the CNS^[2].
