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.

At equivalent molar concentrations, both the salt and free forms of a compound exhibit comparable biological activity. Nevertheless, the salt form (Mecamylamine hydrochloride) usually boasts enhanced water solubility and stability.

    In Vivo

    Mecamylamine (subcutaneous pumps, 50 mg/kg/day, 2 days) inhibits choroidal neovascularization (CNV) in CNV mice model[4].
    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[5].

    Animal Model: Choroidal neovascularization (CNV) mice model[1]
    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[5]
    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.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
