生物活性
ONO-2952 is a potent, selective and orally active translocator protein 18 kDa (TSPO) antagonist with K i of 0.33-9.30 nM for rat and human TSPO. ONO-2952 is more selective for TSPO than other receptors, transporters, ion channels and enzymes. ONO-2952 exerts its anti-stress effects through inhibition of excessive activation of noradrenergic system in the brain without the amnesic effect. ONO-2952 has the potential for irritable bowel syndrome treatment.

Ki: 0.33-9.30 nM (Rat and human TSPO)
体外研究(In Vitro)
As for its selectivity for TSPO, ONO-2952 at a concentration of 10 μM showed good selectivity for TSPO against 98 off-targets (<50% inhibition). Determination of ONO-2952 Ki or IC50 values for the remaining 35 targets (50% inhibition at 10 μM) reveal Ki values of less than 1 μM only for 3 receptors, i.e. melatonin 2, progesterone B, and adrenergic α2C. The affinity of ONO-2952 for these receptors is at least 59 times lower than that for TSPO. ONO-2952 Ki value for the GABAA receptor is more than 600 times higher than that for TSPO. has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
ONO-2952 (0.03-3 mg/kg; oral administration; male Sprague Dawley rats) treatment dose-dependently suppresses restraint stress-induced defecation in rats with brain TSPO occupancy of more than 50%. ONO-2952 also suppresses conditioned fear stress-induced freezing behavior in rats.
ONO-2952 inhibits both neurosteroid accumulation and noradrenaline release in the brain of rats exposed to acute stress. has not independently confirmed the accuracy of these methods. They are for reference only.

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。
