nitroprusside

Nitroprusside disodium dihydrate (Sodium Nitroprusside Dihydrate) 是一种血管扩张剂，通过在血液中自发释放 NO 发挥作用。它可在谷胱甘肽耗竭的成骨细胞中诱导自噬，用于急性高血压和心力衰竭的研究。

Sodium Nitroprusside (Ro 21-2498) 是一种血管舒张剂，能促使 NO 释放到血液中。

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......
