Chlorphenoxamine

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