Mecamylamine (0.5-9 μM) in bath solution increases the frequency of firing in 5-HT DRN (dorsal raphe nucleus) neurons that have been identified [1]. Mecamylamine increases glutamatergic and decreases GABAergic input to 5-HT DRN neurons when administered in bath solution at concentrations of 0.5–9 μM [1]. In spiral cut strips of rabbit aorta, mecamylamine (1 mM, 5 min) inhibits histamine receptors and histamine-induced contraction [2]. Nicotine's neuroprotective effects are lessened by mecamylamine (10 μM, 48 h) [3]. Mecamylamine (1-100 nM, 30 min) in HDMVEC attenuates the formation of endothelial tubes in a dose-dependent manner [4].

| ln Vivo |
Using a CNV mouse model, mecamylamine (subcutaneous pump, 50 mg/kg/day, 2 days) inhibits choroidal neovascularization (CNV) [4]. Dependent on β2 and α7 subtypes, mecamylamine (ip, 0.5-1 mg/kg) has antidepressant-like effects in the tail suspension test (TST) and forced swim test (FST) in C57BL/6J mice. base[5].

| ADME/Pharmacokinetics |
Absorption, Distribution and Excretion
Mecamylamine is almost completely absorbed from the gastrointestinal tract Mecamylamine is excreted slowly in the urine in the unchanged form. The rate of its renal elimination is influenced markedly by urinary pH. Alkalinization of the urine reduces, and acidification promotes, renal excretion of mecamylamine. Mecamylamine crosses the blood-brain and placental barriers. |

| Additional Infomation |
Mecamylamine is a primary aliphatic amine.
A nicotinic antagonist that is well absorbed from the gastrointestinal tract and crosses the blood-brain barrier. Mecamylamine has been used as a ganglionic blocker in treating hypertension, but, like most ganglionic blockers, is more often used now as a research tool. Mecamylamine has been reported in Wettsteinia inversa with data available. A nicotinic antagonist that is well absorbed from the gastrointestinal tract and crosses the blood-brain barrier. Mecamylamine has been used as a ganglionic blocker in treating hypertension, but, like most ganglionic blockers, is more often used now as a research tool. See also: Mecamylamine Hydrochloride (has salt form); Dexmecamylamine (narrower). Drug Indication For the treatment of moderately severe to severe essential hypertension and in uncomplicated cases of malignant hypertension Mechanism of Action Mecamylamine is a ganglionic blocker which prevents stimulation of postsynaptic receptors by acetylcholine released from presynaptic nerve endings. The hypotensive effect of Mecamylamine is attributed to reduction in sympathetic tone, vasodilation, and reduced cardiac output, and is primarily postural. Pharmacodynamics Mecamylamine is a potent, oral antihypertensive agent and ganglion blocker, and is a secondary amine. Mecamylamine is indicated for the management of moderately severe to severe essential hypertension and in uncomplicated cases of malignant hypertension. Mecamylamine reduces blood pressure in both normotensive and hypertensive individuals. A small oral dosage often produces a smooth and predictable reduction of blood pressure. Although this antihypertensive effect is predominantly orthostatic, the supine blood pressure is also significantly reduced. Mecamylamine crosses the blood-brain and placental barriers. |

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
