应用： 盐酸普瑞迪芬可用作内标，用气相色谱-质谱联用（GC-MS）测定人尿样中的 O-去甲基曲马多、曲马多和 N-去甲基曲马多镇痛剂。 SKF-525A HCl (Proadifen) has many biochemical functions, some of which include: inhibitory effects on NOS1 (neuronal nitric oxide synthase; IC50 = 90 mM), adult mouse skeletal muscle AChR (acetyl choline receptor), hepatic drug metabolism via the CYP (cytochrome P450) system, CYP-dependent (cytochrome P450-dependent) arachidonate metabolism (90% at 50 μM), transmembrane calcium influx, and platelet thromboxane synthesis. This compound has also been shown to block KIR6.1 (ATP-sensitive inward rectifier potassium channel 8; IC50 = 4.4 mM) and stimulate endothelial cell prostacyclin production. An inhibitor of NOS1, AChR, cytochrome P-450, and KIR6.1.
