基本描述

别名 地氯雷他定
英文别名 8-Chloro-6,11-dihydro-11-(4-piperidinylidene)-5H- benzo[5,6]cyclohepta[1,2,b]pyridine
规格或纯度 >98.0%(HPLC)(T)
英文名称 Desloratadine
生化机理 It is a selective and nonsedating histamine H1 receptor antagonist, an active metabolite of loratadine (Claritin), used to relieve hay fever and allergy symptoms with less drowsiness than other antihistamines; does not significantly inhibits cardiac K+ channels at clinically achievable blood levels. Free from antimuscarinic/anticholinergic effects.Highly potent, selective H 1 receptor antagonist (K i = 0.97 pM). Inhibits release of inflammatory mediators, including IL-4, IL-6, IL-8, IL-13, PGD(2), leukotriene C4 and tryptase. Anti-inflammatory and antihistaminergic. Orally active. Active in vivo an

产品介绍

Desloratadine is a potent and selective histamine H1-receptor agonist with a half life of 21-24 hours. Experiments sμggest that this compound also exerts antioxidant effects in vitro. Other studies show that H1-receptor binding by desloratadine is reversible and that, over time, desloratadine dissociates from membrane H1-recepters. Desloratadine has also demonstrated the ability to block ICAM-1 upregulation and NFκB activation in primary bronchial and transformed respiratory epithelial cells in vitro.Desloratadine是人H1受体拮抗剂。
