Chlorphenoxamine (hydrochloride)

Chlorphenoxamine hydrochloride, an antihistamine and anticholinergic agent is a GPCR antagonist. Chlorphenoxamine hydrochloride inhibits multiple lethal viral diseases, such as SARS-CoV, MERS-CoV, EBOV and malaria. Chlorphenoxamine hydrochloride shows anti-filovirus activity against both EBOV and Marburg virus (MARV) with IC50s of 1.1 μM and 6.2 μM, respectively. Chlorphenoxamine hydrochloride is used for allergic conditions, urticaria, viral diseases and Parkinson’s disease[1][2][3][4][5].
