Epinastine (WAL801) 是一种抗组胺剂和肥大细胞稳定剂。Epinastine 是一种有效的,选择性的,口服活性的组胺 H1 受体 (histamine H1 receptor) 拮抗剂。Epinastine 还抑制人嗜酸性粒细胞释放 IL-8 并具有抗过敏作用。 在相同实验条件下,摩尔浓度相同的化合物盐形式与游离态具有相同的生物活性,但盐形式 Epinastine hydrochloride 的水溶性和稳定性通常比游离态更好。

产品描述 | Epinastine (WAL801), a potent, selective, and orally-active antihistamine and mast cell stabilizer, functions as a histamine H1 receptor antagonist. It also inhibits IL-8 release from human eosinophils, showcasing antiallergic action [1] [2] [3] [4]. |
体外活性 | Epinastine can displace specific [ 3 H]NC-5Z binding at low concentrations in the locust nervous tissue. Epinastine binds to the honey bees neuronal octopamine receptor with K i of 1.1 nM. Epinastine antagonises octopamine-induced cAMP formation in the insect brain [2]. Epinastine results in an inhibition of histamine release from rat peritoneal mast cells induced by both antigen-antibody reaction and compound 48/80. Epinastine is similarly effective in inhibiting compound 48/80-induced histamine release not only from isolated rat peritoneal mast cells but also from rat mesenterial pieces. Epinastine is effective in inhibiting not only Ca 2+ uptake into lung mast cells in actively sensitized guinea pigs but also Ca 2+ release from the intracellular Ca store of rat peritoneal mast cells exposed to both compound 48/80 and substance P [3]. Epinastine shows a dose- and time-dependent suppressive effect on IL-8, one of the chemokines for eosinophils, released from eosinophils isolated from atopic diseases [4]. |
体内活性 | In receptor binding studies, Epinastine shows a high affinity to H1-receptors in the guinea pig ileum. Epinastine inhibits histamine-induced reactions in the skin or the lung of rats, dogs and guinea pigs [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。
