Isopimaric acid
Based on 1 Customer Validation
Isopimaric acid is a coniferous tree defense compound. Isopimaric acid binds to AKT and inhibits mTOR phosphorylation, thereby regulating the AKT/mTOR pathway. Isopimaric acid inhibits oxidative stress, inflammation, microglial migration, apoptosis, autophagic flux, ornithine decarboxylase activity, breast cancer proliferation and metastasis, and fungal spore germination. Isopimaric acid also induces M2 microglial polarization, mitochondrial damage, ROS accumulation, starvation-induced colon cancer cell apoptosis, and breast cancer cell cycle arrest. Isopimaric acid activates potassium channels, regulates sodium channels and calcium channels, reduces myocardial excitability, and improves arrhythmia. Isopimaric acid acts as an oxidative substrate for CYP6BW1/3, down-regulates PINK1/Parkin, and regulates calcium homeostasis, oxidative phosphorylation, EMT, and the Wnt pathway. Isopimaric acid exhibits activity against drug-resistant Staphylococcus aureus, repels feeding, and promotes the growth of rice seedlings. Isopimaric acid is suitable for research related to epilepsy, tumors, drug-resistant bacterial infections, atrial fibrillation, hypertension, hyperlipidemia, pulmonary tuberculosis, etc.

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 (8.27 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.
Please enter the basic information of animal experiments:

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
