Bupropion, chemically (±)-1-(3-chlorophenyl)-2-(1-piperidinyl)propan-1-one (C13H17ClN2O; molecular weight 252.74 g/mol), is a piperidine-based dopamine-norepinephrine reuptake inhibitor. Its structure features a chlorophenyl ring, a piperidine moiety, and a ketone group. Therapeutically, it treats major depressive disorder and aids smoking cessation. Bupropion exhibits low water solubility, a melting point of 100–105°C, and lipophilicity. Mechanistically, it inhibits presynaptic dopamine and norepinephrine reuptake via blockade of their respective transporters, enhancing neurotransmitter availability in synaptic clefts. It lacks significant serotonergic activity, distinguishing it from other antidepressants.
