Based on 1 publication(s) in Google Scholar
Ginkgolic acid C17:1 is a fatty acid synthase (FAS) inhibitor with an IC50 of 10.5 µM. Ginkgolic acid C17:1 shows anti-tumor activity by inhibiting the phosphorylation of STAT3 and inducing apoptosis. Ginkgolic acid C17:1 can block the interaction between S-RBD and ACE2, and has anti-SARS-CoV-2-S pseudovirus activity. Ginkgolic acid C17:1 inhibits the biofilm formation of enterohemorrhagic Escherichia coli and Staphylococcus aureus.

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 (6.67 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.67 mM); Clear solution
