Biological Activity
GSK2194069 (100 nM; 24 h) inhibits fatty acid synthase (FAS) in cancer cell lines (KATO-III, MKN45, A549, SNU-1) without reducing FAS production protein level[1].
GSK2194069 decreases phosphatidylcholine levels in A549 cells with a half-maximum effective concentration (EC50) value of 15.5 ± 9 nM (n = 78), correlating with the decreased palmitate synthesis[1].
GSK2194069 (5 μM and 20 μM) shows higher efficacy in FASN-positive LNCaP cells rather than FASN-negative PC3 cells, with the higher FASN Expression level in LNCaP cells[2].
GSK2194069 (50 μM; 24 h) inhibits the growth of LNCaP-LN3 human prostate cancer cells[3].
GSK2194069 (60.4 nM; 24 h) displays properties of metabolomics, including L-acetyl carnitine, stearoyl carnitine, vaccenyl carnitine, and palmitoyl-L-carnitine decrease in LNCaP-LN3 cells[3].

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 (5.83 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 (5.83 mM); Clear solution
