Biological Activity: Orphenadrine ((±)-Orphenadrine) is a skeletal muscle relaxant and NMDA antagonist that also has antiparkinsonian, antihistamine, antitremor, antispasmodic, and analgesic effects. Orphenadrine inhibits the binding of [3H]MK-801 to the phencyclidine (PCP) binding site of the NMDA receptor. Orphenadrine is also an anticholinergic and CYP2B inducer. Orphenadrine may exert pro-tumor effects, causing CAR nuclear translocation, resulting in microsomal reactive oxygen species (ROS) production and oxidative stress. Orphenadrine also exerts neuronal protection, protecting rat cerebellar granule cells (CGC) from 3-NPA-induced death and has inhibitory potential against neurodegenerative diseases mediated by NMDA receptor overactivation[1][2][3].

Toladryl | 97.23% | Toladryl is a derivative of Diphenhydramine (HY-B0303), capable of penetrating the blood-brain barrier and possessing oral activity, as well as antihistamine and anticholinergic activities. The anticholinergic activity of Toladryl is approximately one-tenth that of Diphenhydramine (HY-B0303), and its protective effect against lethal doses of histamine in guinea pigs is 2 to 4 times that of Diphenhydramine (HY-B0303). The side effects of Toladryl are fewer and milder than those of Diphenhydramine (HY-B0303), but at higher doses, it may cause central nervous system symptoms such as insomnia, agitation, and disorientation. Toladryl can be used for research in allergic diseases. | ||||||||||||||||||||
