| Targets |
Nicotinic acetylcholine receptors at autonomic ganglia (ganglionic blocker).
|
|---|---|
| ln Vitro |
In vitro, Pempidine acts as a ganglionic blocking agent by antagonizing nicotinic acetylcholine receptors at autonomic ganglia. Quantitative in vitro activity data (e.g., IC50 values) is not detailed in publicly available sources.
|
| ln Vivo |
In vivo, Pempidine is an orally bioactive ganglionic blocking agent used in patients with hypertension. It reduces blood pressure by blocking sympathetic ganglionic transmission. Detailed dose-response and pharmacokinetic data are limited in publicly available literature.
|
| Enzyme Assay |
No specific cell-free nicotinic receptor binding assay protocol is detailed for Pempidine. For ganglionic blockers, typical cell-free assays include radioligand binding studies using [3H]epibatidine or [125I]α-bungarotoxin and membrane preparations from tissues expressing nicotinic receptors.
|
| Cell Assay |
Cellular nicotinic receptor antagonism is assessed in cells expressing nicotinic receptors (e.g., ganglionic neurons or heterologous expression systems). Cells are treated with Pempidine and stimulated with nicotine or acetylcholine; inhibition of the response (e.g., ion flux, membrane depolarization) is measured.
|
| Animal Protocol |
In vivo efficacy is evaluated in animal models of hypertension or in clinical use. Pempidine is administered orally. Endpoints include blood pressure, heart rate, and sympathetic nerve activity.
|
| ADME/Pharmacokinetics |
Molecular weight: 155.28 g/mol; molecular formula: C10H21N. CAS No.: 79-55-0. Appearance: clear colorless to light yellow liquid. Boiling point: 187-188°C. Storage: typical for amines (protected from light, inert atmosphere).
|
| Toxicity/Toxicokinetics |
No detailed toxicity data is publicly available. As a ganglionic blocker, potential side effects include orthostatic hypotension, dry mouth, blurred vision, constipation, and urinary retention due to autonomic blockade.
|
| Additional Infomation |
1,2,2,6,6-Pentamethylpiperidine is a type of piperidine compound. It is a nicotine receptor antagonist, most commonly used in laboratory settings. It was once used as a ganglion blocker to treat hypertension, but has since been superseded by more specific drugs.
Pempidine is a research-grade compound and was historically used as an antihypertensive agent. It is not commonly used in modern clinical practice due to the availability of safer antihypertensive drugs. No FDA approval in the US for current use has been reported. Its mechanism involves ganglionic nicotinic receptor blockade. |

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).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
