Background:

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.
