  Product Name    Sirolimus
  CAS#    53123-88-9
  Synonyms    Rapamycin
  中文名    雷帕霉素; 西罗莫司
  Molecular Formula    C51H79NO13


Biochem/physiol Actions Rapamycin is a macrocyclic triene antibiotic possessing potent immunosuppressant and anticancer activity. It forms a complex with FKBP12 that binds to and inhibits the molecular target of rapamycin (mTOR). mTOR is a member of the phosphoinositide kinase-related kinase (PIKK) family that enhances cellular proliferation via the phosphoinositol 3-kinase/Akt signaling pathway. Inhibition of this pathway by rapamycin blocks downstream elements that result in cell cycle arrest in G1. The effectors of mTOR action include 4EBP1 and S6K1.
