Rapamycin (Sirolimus) is a potent and specific mTOR inhibitor with an IC50 of 0.1 nM.
Antifungal and immunosuppressant. Specific inhibitor of mTOR (mammalian target of Rapamycin). Complexes with FKBP-12 and binds mTOR inhibiting its activity. Inhibits interleukin-2-induced phosphorylation and activation of p70 S6 kinase. Induces autophagy in yeast and mammalian cell lines. Drives hPSC differentiation to mesendoderm and blood progenitor cells. Also used as a chemical dimerizer; rapamycin and GA3-AM (Cat. No. 5407) chemically inducible dimerization systems are orthogonal.
