Isopteropodine
Based on 1 Customer Validation
Isopteropodine is a positive modulator that selectively acts on muscarinic M1 and 5-HT2 receptors. Isopteropodine has an EC50 of 9.92 μM for acetylcholine and 14.5 μM for 5-HT. Isopteropodine also has antibacterial activity against Gram-positive bacteria, with MICs of 150 μg/mL and 250 μg/mL for Staphylococcus aureus and Bacillus subtilis, respectively. Isopteropodine enhances receptor function by increasing the affinity of agonists for receptors and can also inhibit the growth of specific Gram-positive bacteria, and can be used in cognitive impairment and antibacterial research.

5-HT2 Receptor |
Isopteropodine (1-30 μM) can enhance the Ca2+-activated Cl- currents induced by acetylcholine and 5-HT in a concentration-dependent manner in Xenopus oocytes expressing rat cortical total RNA, without significant effect on the currents mediated by metabotropic glutamate receptors (mGlu1/5) and ionotropic receptors (NMDA, kainic acid, glycine)[1].
Isopteropodine (353-679 μM; 24 h) has antibacterial activity against Staphylococcus aureus and Bacillus subtilis in vitro, with minimum inhibitory concentrations (MIC) of 408 μM and 679 μM, respectively, without inhibitory effect on fungi[2].

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: ≥ 2.5 mg/mL (6.79 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
