生物活性:
Bupropion (Amfebutamone) hydrobromide is an orally active, selective serotonin reuptake inhibitor (SSRI).Bupropion hydrobromide block dopamine (DA) uptake or Methamphetamine-induced DA release with IC50s of 1.76 μM and 14.2 μM, respectively. Bupropion hydrobromide is an atypical antidepressant that can be used for the research of smoking cessation aid.

体内研究:
Bupropion (Amfebutamone) shows convulsant and anticonvulsant effects in mice. Bupropion dose-dependently causes clonic convulsions in mice, with the CD50 (convulsive dose50, i.e., the dose producing convulsions in 50% of mice) at 119.7 mg/kg.Animal Model:Male Swiss mice weighing 20-25 g
Dosage:100-160 mg/kg
Administration:I.p.
Result:Caused clonic convulsions, with the CD50 and CD97 being 119.7 (104.1-137.6) and 156.7 mg/kg, respectively. When given at a full convulsant dose of 160 mg/kg, the median latency was 6.00 min (3.50-8.15). Tonic convulsions were observed occasionally (1 per 8 mice) only in the groups receiving 140 or 160 mg/kg.

体外研究:
Bupropion (Amfebutamone) inhibits CYP2D6 with the IC50 of 58 μM.Bupropion, an atypical antidepressant, induces endoplasmic reticulum stress and caspase-dependent cytotoxicity in SH-SY5Y cells.Bupropion activates caspase 3 through the induction of endoplasmic reticulum stress responses and activation of JNK, and consequently induces apoptotic cell death in SH-SY5Y cells.Bupropion (1-100 μg/mL) reduces cell viability. Bupropion-induced reduction in cell viability may have been a consequence of apoptotic mechanisms.Bupropion (100 μg/mL) increases the phosphorylated forms of EIF-2α, JNK, and p38 MAPK, and the expression of GRP78 within 1 h.Bupropion is a weak, competitive inhibitor of norepinephrine (NE) uptake into rat hypothalamic synaptosomes and of dopamine (DM) uptake into rat striatal synaptosomes, having IC50 values of 6.5 μM and 3.4 μM, respectively.
