CAY10566
Based on 18 publication(s) in Google Scholar
CAY10566 is a potent, orally bioavailable and selective stearoyl-CoA desaturase1 (SCD1) inhibitor with IC50s of 4.5 and 26 nM in mouse and human enzymatic assays, respectively. CAY10566 also shows excellent cellular activity in blocking the conversion of saturated long-chain fatty acid-CoAs (LCFA-CoAs) to monounsaturated LCFA-CoAs in HepG2 cells (IC50=7.9 nM or 6.8 nM).

CAY10566 purchased from MedChemExpress. Usage Cited in: Redox Biol. 2021 Jan;38:101807. [Abstract]
TEM imaging was conducted in FBW7T205A overexpressed PANC-1 cells. RSL3 (2 μmol/L) and CAY10566 (5 μmol/L) treated PANC-1 cells functioned as the positive control. Red arrows showed the shrunken mitochondria. Blue arrows showed lipid droplets. The values below the western blot band represent the relative mean gray values of three independent experiments. Gray values were calculated by Adobe Photoshop CS6.

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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.41 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (5.34 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
