 emedastine fumarate Biological Activity

DescriptionEmedastine difumarate is an orally active, selective and high affinity histamine H1 receptor antagonist with a Ki value of 1.3 nM. Emedastine difumarate is a benzimidazole derivative with potent antiallergic properties and used for allergic rhinitis, allergic skin diseases and allergic conjunctivitis[1][2][3].

Target

H1 Receptor:1.3 nM (Ki)

H2 Receptor:49067 nM (Ki)

H3 Receptor:12430 nM (Ki)

In VitroEmedastine difumarate inhibits histamine H2 receptor (Ki=49067 nM) and histamine H3 receptor (Ki=12430 nM)[1]. High concentrations of Emedastine difumarate (1 and 10 ng/ml) significantly inhibits type 1 collagen production in normal human dermal fibroblasts[2]. Emedastine difumarate (1, 10, 100, 1000 nM) at concentrations of ≥ 10 nM inhibits CC chemokine-elicited eosinophil migration[2].
In VivoEmedastine difumarate (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[3]. Pretreatment with Emedastine difumarate (0.03, 0.1, 0.3 mg/kg; orally) significantly inhibits the scratching induced by substance P and leukotriene B[3]. Emedastine difumarate (0.3 mg/kg, p.o.) produces significant inhibition of passive peritoneal anaphylaxis in guinea-pigs[2]. Emedastine difumarate inhibits histamine-induced contractions of isolated ileum (IC50=6.1 nM)[2]. Animal Model: Male ICR mice 5-6 weeks of age[3] 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.
