General description

Bupropion is structurally linked to the phenylethylamine family. It is a monocyclic aminoketone (chloropropiophenone).


Bupropion hydrochloride has been used as an anti-depressant and injected into mice intraperitoneally for forced swim test. It has also been used to study its effects on depression, anxiety and smoking cessation.
