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 |

备注 | 如果有可能,您尽量在使用的当天配置溶液,并在当天使用完它。但是,如果您需要预先配制储备溶液,我们建议您将溶液等份保存在-20°C的密封小瓶中。通常,它们最多可以使用一个月。在使用前和打开样品瓶之前,我们建议您让您的产品在室温下平衡至少1小时。需要更多关于溶解度,用法和处理的建议吗?请访问我们的常见问题(FAQ)页面以获取更多详细信息。 |
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。 Desloratadine is a potent and selective histamine H1-receptor agonist with a half life of 21-24 hours.
