| 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. |
| General description | Rapamycin, a macrocyclic triene antibiotic, possesses immunosuppressant, anti-proliferative, and anti-cancer activity. It complexes with FK-binding protein (FKBP12) and inhibits mTOR (FRAP, RAFT), a member of the phosphoinositide kinase-related kinase (PIKK) family. mTOR enhances phosphoinositol 3-kinase (PI3K)/Akt signaling. Inhibition by rapamycin results in cell cycle arrest in G1. |
