Coclaurine
Based on 1 publication(s) in Google Scholar
Coclaurine is a class of tetrahydroisoquinoline alkaloids that can be isolated from Sarcopetalum harveyanum with anticancer activity. Coclaurine is a nicotinic acetylcholine receptor (nAChRs) antagonist. Coclaurine is a key molecule in S. tetrandra responsible for EFHD2 inhibition. Coclaurine can downregulate EFHD2-related NOX4-ABCC1 signaling and enhanced Cisplatin (HY-17394) sensitivity. Coclaurine suppresses the stemness and metastatic properties of NSCLC cells. Coclaurine disrupts the interaction between the transcription factor FOXG1 and the EFHD2 promoter, leading to a reduction in EFHD2 transcription.

Solvent & Solubility
DMSO : 100 mg/mL (350.46 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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
