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

靶点活性 | TSPO (rat and human):(ki)0.33-9.30 nM |
体外活性 | ONO-2952 at a concentration of 10 μM displayed good selectivity for TSPO against 98 off-targets (<50% inhibition). ONO-2952 Ki value for the GABAA receptor is more than 600 times higher than that for TSPO. Determination of ONO-2952 Ki or IC50 values for the remaining 35 targets (50% inhibition at 10 μM) reveals 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 [1]. |
体内活性 | ONO-2952 inhibits both neurosteroid accumulation and noradrenaline release in the brain of rats exposed to acute stress. ONO-2952 also inhibits conditioned fear stress-induced freezing behavior in rats. ONO-2952 (0.03-3 mg/kg; p.o.; male Sprague Dawley rats) treatment dose-dependently inhibits restraint stress-induced defecation in rats with brain TSPO occupancy of more than 50% [1]. |

对于不同动物的给药剂量换算,您也可以参考 更多...
请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
