产品描述 Asapiprant (S-555739) is a potent and selective DP1 receptor antagonist (Ki: 0.44 nM). It exhibited high affinity and selectivity for the DP1 receptor.
靶点活性 DP1 receptor:0.44 nM (Ki)
体外活性 Asapiprant strongly inhibited the cAMP elevation elicited by PGD2 in human platelets with a half-maximal inhibitory concentration (IC50) value of 16 nM. Strong inhibition by asapiprant was observed in the cAMP elevation induced by PGD2 in guinea pigs, rats, and sheep with IC50 values (nM) of 61, 74, and 15, respectively.
体内活性 Intranasal challenge with 0.5% PGD2 led to a rapid increase in nasal resistance (sRaw) from 5 min to 60 min in sensitized guinea pigs. Oral administration of asapiprant at 1 and 3 mg/kg significantly suppressed the increase in nasal resistance by 82% and 92%, respectively. By contrast, S-5751 showed partial suppression on PGD2-induced nasal resistance in guinea pigs at 30 mg/kg by 76% that was inferior to the suppression by asapiprant at 3 mg/kg.
细胞实验 The functional antagonist activity of asapiprant on the DP1 receptor was evaluated by examining PGD2-induced elevation of cyclic adenosine monophosphate (cAMP) in platelet-rich plasma derived from venous blood (humans, guinea pigs, and sheep), and in rat DP1-transfected cells stimulated with PGD2, as described elsewhere. The functional antagonist activity of asapiprant on the DP2 receptor was evaluated by examining PGD2-induced shape change of peripheral eosinophils derived from humans and guinea pigs, as reported previously.
动物实验 After the oral administration of asapiprant or S-5751 to rats, guinea pigs, dogs, and sheep at 10 mg/kg in suspension with 0.5% methylcellulose solution, the plasma concentrations of the drugs were measured by liquid chromatography/tandem mass spectrometry or high-performance liquid chromatography.

TargetMol Calculator 体内实验配液计算器

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。
