Biological Activity
Ki: 500 nM (Nicotinic receptor) and 11000 nM (Muscarinic receptor)[1]
Lupanine shows binding affinity for nicotinic receptor with a Ki value of 500 nM. While, Lupanine shows a very weak affinity for the muscarinic receptor with a Ki value of 11000 nM[1].
Lupanine (0-100 μM) is a weak agonist and desensitizer in SH-SY5Y cells, with EC50 and DC50 of 10.7 μM and 28.2 μM, respectively[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Lupanine (1-7.5 mg/kg; i.v.) is more efficient than Sparteine for antagonizing secondary reflex hypertension in carotid occlusion and hypotension resulting from the stimulation of the pneumogastric nerve in both the cat and the dog[1].
Lupanine has an inhibitory action on nicotinic type hypertension produced by injection of Acetylcholine (500 p.g/kg i.v.) in the Atropine-treated dog[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1.25 mg/mL (5.03 mM); Clear solution
This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 1.25 mg/mL (5.03 mM); Clear solution
This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
