Fexofenadine (MDL-16455) hydrochloride 是一种具有口服活性和非镇静性的H1受体拮抗剂。Fexofenadine hydrochloride 可用于过敏性鼻炎和慢性特发性荨麻疹的研究。
生物活性 | Fexofenadine (MDL-16455) hydrochloride is an orally active and nonsedativeH1receptorantagonist. Fexofenadine hydrochloride can be used in allergic rhinitis and chronic idiopathic urticarial research[1][2][3]. |
IC50& Target[1] | |
体外研究 (In Vitro) | Fexofenadine (1-100 μM; 1 h) inhibits the expression of IL-6 protein in nasal fibroblasts in a dose-dependent manner[2]. Fexofenadine (1-100 μM; 1 h) blocks phosphorylated p38 activation in histamine-induced nasal fibroblasts, but shows no effect on either pERK or pJNK[2].
Western Blot Analysis[2] Cell Line: | Nasal Fibroblasts | Concentration: | 100 μM | Incubation Time: | 1 hour | Result: | Blocked pp38 activation in histamine-induced nasal fibroblasts, showed histamine-induced IL-6 production mediated by the p38 pathway. |

体内研究 (In Vivo) | Fexofenadine hydrochloride (oral administration; 5-20 mg/kg; once daily; 3 w) suppresses both eosinophilia and systemic anaphylaxis in C57BL/6 mice infected withT. spiralis[1].
Animal Model: | C57BL/6 mice infected withTrichinella spiralis[1] | Dosage: | 5, 10 and 20 mg/kg | Administration: | Oral administration; 5, 10 and 20 mg/kg; once daily; 3 weeks | Result: | Inhibited eosinophilia in a dose-dependent manner. Suppressed the decrease in rectal temperature (p<0.01), a marker for systemic anaphylaxis. |
