Everolimus, also known as RAD001, is a potent and orally bio-available inhibitor of mammalian target of rapamycin (mTOR), a key component of active PI3K/Akt pathway in human cancers. It binds to intracellular receptor FKBP12 in the mTOR pathway with high affinity forming an everolimus-FKBP12 complex. The complex further binds to mTOR resulting in reducing the activity of the downstream effectors S6 ribsomal protein kinase (S6K1) and translational repressor protein eukaryotic elongation factor 4E-binding protein (4EBP). Besides its immunosuppressive activity for the prevention of organ transplant rejection, everolimus exhibits antineoplastic activity and is currently used to treat renal cell cancer and other tumors.

Cell lines
The pancreatic tumor cell line Panc-1 and the small cell lung cancer cell line ScLc.
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.
Reaction Conditions
IC50: 50 μg/mL (Panc-1); 5 μg/mL (ScLc), 24h
Applications
Everolimus exerted antiproliferation activity. It dose-dependently inhibited BrdU incorporation in Panc-1 and ScLc with IC50 values of 50 μg/mL and 5 μg/mL, respectively. Both are high concentrations that would not be possible in humans. Therapeutic serum levels of everolimus range between 0.005 and 0.01 μg/mL.
Animal models
TgMISIIR-TAg-DR26 mice model of ovarian cancer
Dosage form
RAD001 was formulatedat 2% (w/v) in a microemulsion vehicle and was diluted in double-distilled water just before administration by gavage. Mice were treated with placebo (control) or 5 mg/kg of RAD001 twice weekly started from age of 5 weeks and continued to 20 weeks. Mice treated with placebo or RAD001 were scanned by MRM.
RAD001 suppressed tumorigenesis. Body weights of RAD001-treated mice were ~10% lower than in placebo treated mice.
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.
