General tipsFor obtaining a higher solubility, please warm the tube at 37°C and shake it in the ultrasonic bath for a while. Stock solution can be stored below -20°C for several months.


Cell experiment [1]:

Cell lines

Patient-derived AC-UPS01 and AC-RMS01 cell lines

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37°C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20°C for several months.

Reacting condition

0.25, 0.5, 1, 2.5 and 5 mM; 72 h


Caffeine significantly inhibited the patient-derived UPS and RMS cell lines in a dose-dependent manner with IC50 values of 2.02 ± 0.22 mM and 2.37 ± 0.48 mM, respectively. Addition of 0.3 mM or 0.6 mM VPA to varying concentrations of CAF enhanced efficacy against both the AC-UPS01 and AC-RMS01 cell lines.

Animal experiment [2]:

Animal models

diet-induced obesity (DIO) mice

Dosage form

10 μg per mouse, i.c.v. administration


In diet-induced obesity (DIO) mice, administration of caffeine into mouse brain significantly increased the numbers of c-Fos+ cells in the PVN, Arc and DMH nuclei, suggesting that caffeine stimulated the activities of neurons in the hypothalamic nuclei involved in energy balance control. Caffeine reduced the adipocyte sizes of epididymal white adipose tissue, plasma triglycerides (TG) levels and improved glucose tolerance. Mice gained significantly less body weights than the controls on day 7.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
