生物活性:
Mecamylamine is an orally active, nonselective, noncompetitive nAChR antagonist. Mecamylamine is also a ganglionic blocker. Mecamylamine can across the blood-brain barrier. Mecamylamine can be used in the research of neuropsychiatric disorders, hypertension, antidepressant area.

体内研究:
Mecamylamine (subcutaneous pumps, 50 mg/kg/day, 2 days) inhibits choroidal neovascularization (CNV) in CNV mice model.Mecamylamine (intraperitoneal injection, 0.5-1 mg/kg) has antidepressant-like effects in both the TST (tail suspension test) and FST (forced swim test) in C57BL/6J mice, which are dependent on both β2 and α7 subunits.Animal Model:Choroidal neovascularization (CNV) mice model
Dosage:50 mg/kg/day, 2 days
Administration:Subcutaneous pumps implanted beneath the skin of the back, 200 μL and mean pumping rate of 0.5 μL/h.
Result:Suppressed the development of CNV at Bruch’s membrane rupture sites in the absence of nicotine.
Animal Model:C57BL/6J mice
Dosage:0.5-1 mg/kg
Administration:Intraperitoneal injection
Result:Had no effect in β2 knockout mice and α7 knockout mice, but decreased immobility time in wildtype littermates in the FST.

体外研究:
Mecamylamine (0.5-9 μM, bath administered) increases the firing frequency of identified 5-HT DRN (dorsal raphe nucleus) neurons.Mecamylamine (0.5-9 μM, bath administered) increases the glutamatergic and decreases the GABAergic input of 5-HT DRN neurons.Mecamylamine (1 mM, 5 min) blocks the histamine receptor and the histamine-induced contractions in helically cut strips of rabbit aorta.Mecamylamine (10 μM,48 h) attenuates the effect of nicotine’s action of neuroprotection.Mecamylamine (1-100 nM, 30 min) dose-dependently attenuates endothelial tube formation in HDMVECs.
