产品描述	Irdabisant hydrochloride (CEP-26401) is a selective, orally active, and blood-brain barrier (BBB) penetrant histamine H3 receptor (H3R) inverse agonist/inverse agonist, demonstrating high affinity with Ki values of 7.2 nM and 2.0 nM for rat and human H3R respectively. It exhibits relatively low hERG current inhibitory activity, with an IC50 of 13.8 μM. This compound has been shown to enhance cognition and promote wakefulness in rat social recognition models, suggesting potential applications in schizophrenia or cognitive impairment research.
体外活性	Irdabisant (CEP-26401, compound 8a) shows antagonist activity with K b, app values of 1.0 nM and 0.4 nM for rat H3R and human H3R, respectively; shows inverse agonist activity with EC 50 values of 2.0 nM and 1.1 nM for rat H3R and human H3R, respectively [1]. Irdabisant has moderate activity at Muscarinic M 2 (K i = 3.7 ± 0.0 μM) and Adrenergic α 1A (K i = 9.8 ± 0.3 μM) receptors, Dopamine transporters (K i = 11 ± 2 μM), Norepinephrine transporters (K i = 10 ± 1 μM), and phosphodiesterase PDE3 (IC 50 = 15 ± 1 μM) [1]. Irdabisant inhibits the cytochrome P450 enzymes CYP1A2, 2C9, 2C19, 2D6, and 3A4 with IC 50 values of greater than 30 μM, indicating less potential for drug-drug interactions [1].
体内活性	CEP-26401 (0.01-0.3 mg/kg; p.o.; single dosage) dose-dependently inhibits H3R agonist RAMH -induced dipsogenia [1]. CEP-26401 (0.0001-0.1 mg/kg; i.v. or p.o.; single dosage) improves performance in the rat social recognition model of short-term memory [1]. CEP-26401 (3-30 mg/kg; p.o.; single dosage) exhibits wake-promoting activity in rat [2]. CEP-26401 (3-30 mg/kg; i.p.) increases prepulse inhibition (PPI) in DBA/2NCrl mice [2]. CEP-26401 (1 mg/kg for i.v. and 3 mg/kg for p.o.; single dosage) is rapidly absorbed with high oral bioavailability in rat and monkey, and shows a moderate clearance in monkey and dog compared to the rat [1]. Pharmacokinetic Parameters of Irdabisant (compound 8a) in rats, dogs and monkeys [1]. Rat Dog Monkey i.v. t 1/2 (h) 2.6 2.9 5.4 i.v. V d (L/kg) 9.4 3.5 ± 1.1 3.8 ± 0.9 i.v.

F (%) 83 22 ± 2 83 ± 18 Brain to plasma ratio 2.6 ± 0.2 2.4 ± 0.4 / Animal Model: Male Sprague-Dawley rats (i.p. 10 mg/kg RAMH-induced dipsogenia model) [1] Dosage: 0.01-0.3 mg/kg Administration: p.o.; single dosage Result: Dose-dependently inhibited H3R agonist RAMH -induced dipsogenia (which manifests as water drinking) with an EC 50 value of 0.06 mg/kg. Animal Model: Male Sprague-Dawley rats (adult rats were briefly exposed to a juvenile rat for build social recognition model) [2] Dosage: 0.0001, 0.001, 0.01 and 0.1 mg/kg for i.p.; 0.01 and 0.1 mg/kg for p.o. Administration: i.v. or p.o.; single dosage Result: Effectively reduced the ratio of investigation duration (RID) at doses over the range from 0.001 to 0.1 mg/kg i.p. and at 0.01 and 0.1 mg/kg p.o., demonstrating potent enhancement of short-term sensory memory in this model. Animal Model: Male Sprague-Dawley rats [2] Dosage: 3, 10 and 30 mg/kg Administration: p.o.; single dosage Result: Exhibited robust wake promotion with the treated animals awake 90% of the time up to 3 h postdosing at 30 mg/kg. Animal Model: Male Sprague-Dawley rats, male beagle dogs and male cynomolgus monkeys [1] Dosage: 1 mg/kg for i.v. and 3 mg/kg for p.o. Administration: i.v. and p.o. Result: Exhibited rapid absorption with high oral bioavailability in rat and monkey, and showed a moderate clearance in monkey and dog compared to the rat. Animal Model: Male DBA/2NCrl mice (19-27 g; 7-9 weeks) [2] Dosage: 3, 10 and 30 mg/kg Administration: i.p.; single dosage Result: Increased prepulse inhibition (PPI) in DBA/2NCrl mice, whereas the antipsychotic Risperidone is effective at 0.3 and 1 mg/kg i.p..

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。
