生物活性

A-740003 is a potent, selective and competitive P2X7 receptor antagonist with IC₅₀ values are 18 and 40 nM for rat and human P2X7 receptors, respectively.

体外研究

A 438079 or A 740003 (10 μM) significantly blocks the sustained phase of the BzATP-induced response. A-740003 infusion reduces SE-induced TNF-α expression in dentate granule cells. A-740003 infusions increases SE-induced neuronal death. A-740003 and A-438079 show significantly greater potency in blocking P2X7 receptor activation across all species compared with other antagonists. A-740003 and A-438079 show greater activity at rat and human, as compared with mouse P2X7 receptors. A-740003 potently blocks agonist-evoked IL-1β release with (IC₅₀=156 nM) and pore formation (IC₅₀=92 nM) in differentiated human THP-1 cells.

体内研究

Systemic administration of A-740003 produces dose-dependent antinociception in a spinal nerve ligation model (ED₅₀=19 mg/kg i.p.) in the rat. A-740003 also attenuates tactile allodynia in two other models of neuropathic pain, chronic constriction injury of the sciatic nerve and vincristine-induced neuropathy. In addition, A-740003 effectively reduces thermal hyperalgesia observed following intraplantar administration of carrageenan or complete Freund's adjuvant (ED₅₀=38-54 mg/kg i.p.). A-740003 is ineffective in attenuating acute thermal nociception in normal rats and does not alter motor performance at analgesic doses.

请依序添加每种溶剂： 10% DMSO 40% PEG300 5% Tween-80 45% saline
Solubility: ≥ 2.5 mg/mL (5.27 mM); Clear solution

此方案可获得 ≥ 2.5 mg/mL (5.27 mM，饱和度未知) 的澄清溶液。
以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；向上述体系中加入50 μL Tween-80，混合均匀；然后继续加入 450 μL生理盐水定容至 1 mL。
