fenspiride

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 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-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......
