orphenadrine

Orphenadrine 是一种非竞争性的 N-甲基-D-天冬氨酸（NMDA）受体拮抗剂，以浓度依赖性方式抑制克隆的 HERG 通道，在 HEK 细胞中产生0.85μM 的 IC。Orphenadrine 是中枢和外周毒蕈碱受体的拮抗剂，通过孔残基 Y652或 F656突变阻断衰减。 Orphenadrine 具有抗痉挛、镇痛和抗胆碱能活性，对在体外和体内对谷氨酸神经毒性具有保护作用。Orphenadrine 对钠离子通道具有抑制作用，可用来治疗帕金森。

Orphenadrine hydrochloride (Mephenamin) 是一种非竞争性的NMDA 受体拮抗剂, Ki=6.0 ± 0.7 μM。

Orphenadrine Citrate (Flexon) 是NMDA 受体拮抗剂，Ki 为6.0μM，还是HERG 钾离子通道阻断剂。它是一种骨骼肌松弛剂，它作用于中枢神经系统以产生肌肉松弛作用。

Tofenacin (free base) is an antidepressant drug with a tricyclic-like structure. It acts as a serotonin-norepinephrine reuptake inhibitor, and based on its close relation to orphenadrine, may also possess anticholinergic and antihistamine properties. Tofenacin is also the major active metabolite of orphenadrine and likely plays a role in its beneficial effects against depressive symptoms seen in Parkinson's disease patients.
