fenspiride

Fenspiride 是 H1-组胺受体的拮抗剂。 Fenspiride 是一种具有口服活性的非甾体类抗炎药，可用于治疗呼吸道感染和中耳炎。 Fenspiride 抑制磷酸二酯酶 4 和磷酸二酯酶 3 的活性，-logIC50 值分别为 4.16+ -0.09 和 3.44+ -0.12。 磷酸二酯酶 5 活性也受到抑制，-logIC50 值约为 3.8。

Fenspiride hydrochloride (Decaspiride) 是一种口服活性的非甾体抗炎剂，是 H1-组胺受体的拮抗剂，可用于呼吸系统疾病的研究。

Fenspiride-d5 is intended for use as an internal standard for the quantification of fenspiride by GC- or LC-MS. Fenspiride is an antagonist of histamine H1 receptors and a non-steroidal anti-inflammatory drug (NSAID). It inhibits histamine-induced contraction of isolated guinea pig trachea but not histamine-induced inotropy of isolated guinea pig heart. It also inhibits phosphodiesterase 4 (PDE4), PDE5, and PDE3 (IC50s = 69, ~158, and 363 µM, respectively, in isolated human bronchi derived from patients with lung cancer). It is selective for these phosphodiesterases over PDE1 and PDE2, where it provides less than 25% inhibition. Fenspiride potentiates the airway relaxant effects of isoproterenol and sodium nitroprusside indicating an effect on cAMP and cGMP phosphodiesterases, respectively. Aerosolized fenspiride (1 mg ml) reverses bronchoconstriction induced by capsaicin and, when used at aerosolized concentrations ranging from 1-10 mg ml, reduces cough induced by citric aci......
