| Selectively inhibits the mammalian target of rapamycin (mTOR) and blocks the subsequent activation of p70 S6 kinase (IC50=50pM). Specifically inhibits mTORC1, but mTORC2 that phosphorylates Akt at Ser473 appears to be insensitive to rapamycin. Prevents the translational activation of IGF-II. Also prevents resting T-cells from entering the cell cycle, but does not directly arrest cell cycle progression. Shown to inhibit later signaling events, such as p110Rb phosphorylation, p34cdc2 kinase activation, and cyclin A synthesis. Exhibits strong binding to FK-506 binding proteins. Also reported to induce apoptosis in a murine B-cell line, to inhibit lymphokine-induced cell proliferation at the G1 phase, and to irreversibly arrest Saccharomyces cerevisiae cells in the G1 phase. | | | Catalog # | 029598 | | Solubility | DMSO (25mg/ml) Ethanol (9mg/ml) or Methanol (1mg/ml) | | Storage and Stability | Lyophilized powder may be stored at -20°C.
