- 产品描述： Emedastine is an orally active, selective and high affinity histamine H1 receptor antagonist with a Ki value of 1.3 nM. Emedastine is a benzimidazole derivative with potent antiallergic properties and used for allergic rhinitis, allergic skin diseases and allergic conjunctivitis
- 靶点： H1 Receptor:1.3 nM (Ki);H2 Receptor:49067 nM (Ki);H3 Receptor:12430 nM (Ki)
- 体内研究： Emedastine (0.03, 0.1, 0.3 mg/kg; orally; pretreatment of 30 min) significantly suppresses histamine-induced scratching with 0.1 and 0.3 mg/kg but not 0.03 mg/kg. Pretreatment with Emedastine (0.03, 0.1, 0.3 mg/kg; orally) significantly inhibits the scratching induced by substance P and leukotriene B. Emedastine (0.3 mg/kg, p.o.) produces significant inhibition of passive peritoneal anaphylaxis in guinea-pigs. Emedastine inhibits histamine-induced contractions of isolated ileum (IC50=6.1 nM). Animal Model: Male ICR mice 5-6 weeks of age Dosage: 0.03, 0.1, 0.3 mg/kg Administration: Orally; 30 min before pruritogen injection Result: Significantly suppressed histamine-induced scratching with pretreatment of 0.1 and 0.3 mg/kg.
