10.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 200 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to make it clear; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 Ridaforolimus (Deforolimus, MK-8669, AP23573) is a selective mTOR inhibitor with IC50 of 0.2 nM in HT-1080 cell line; while not classified as a prodrug, mTOR inhibition and FKBP12 binding is similar to rapamycin. Phase 3.
in vitro

Treatment of HT-1080 cells with Deforolimus induces a dose-dependent inhibition of phosphorylation of both S6 and 4E-BP1, with IC50 of 0.2 nM and 5.6 nM, respectively, and leads to a decrease in cell size, an increase in the proportion of cells in the G1 phase of the cell cycle, and inhibition of glucose uptake. Deforolimus displays significant antiproliferative activity a broad panel of cell lines with EC50 of 0.2-2.3 nM. Deforolimus potently and selectively inhibits VEGF production in a dose-dependent manner. [1] Deforolimus treatment significantly induces growth suppression in human NSCLC cell lines with IC30 values of 2.45-8.83 nM, with the exception of H157 with IC30 of >20 nM. Deforolimus treatment (2.8-5.9 nM) significantly dephosphorylates p70S6KThr389 in A549, H1703 and H157 cells, except H1666 that may express a resistant variant of mTORC1, and causes increased phosphorylation of pAKTser473 and pAKTThr308 in A549 and H1703 cells. Deforolimus in combination with the MEK inhibitors, CI-1040 or PD0325901 exhibits dose-dependent synergism in lung cancer cell lines, which is associated with the suppression of proliferation rather than enhancement of cell death, involving the inhibition of ribosomal biogenesis by 40% within 24 hours and a decreased polysome/monosome ratio. [2]

in vivo

Administration of Deforolimus exerts significant antitumor effects in mice bearing PC-3 (prostate), HCT-116 (colon), MCF7 (breast), PANC-1 (pancreas) or A549 (lung) xenografts in a dose-dependent manner, and inhibits mTOR signaling in in SK-LMS-1 xenograft model associated with inhibition of tumor growth.

プロトコル(参考用のみ)

キナーゼアッセイ Cell based target inhibition
HT-1080 cells are treated with increasing concentrations of Deforolimus (0-100 nM) for 2 hours, prior to harvest. Cellular lysates are extracted in denaturing lysis buffer, resolved on SDS-PAGE and transferred to PVDF membranes. After blocking, membranes are incubated with primary antibodies for 1 hour, followed by appropriate HRPconjugated secondary antibodies for 1 hour at room temperature. Immunoreactive proteins are detected using enhanced chemiluminescence and autoradiography performed by exposure to X-ray film. IC50 is determined from the inhibition of levels of phosphorylated ribosomal protein S6 (p-S6) and 4E-BP1 (p-4E-BP1).
細胞アッセイ 細胞株 Colo205, H1755, H1395, H1666, A549, H157, and H1703 cells
濃度 Dissolved in ethanol, final concentrations ~ 1 μM
反応時間 72-120 hours
実験の流れ

Cells are seeded at 2-3 × 104/mL, and serial dilutions of Deforolimus are added after 2 hours, for at least three cell doublings (72-120 hours). Deforolimus effects are measured using the CellTiter 96 Aqueous nonradioactive cell proliferation assay and Sulforhodamine B assays. For Deforolimus, growth effects are described as IC30 because rapamycin and its derivatives do not significantly impede cell proliferation.

動物実験 動物モデル Male and female athymic NCr-nu mice with xenografts established by subcutaneous implantation of PC-3, A549, HCT-116, MCF7, PANC-1 and SK-LMS-1 tumors
投薬量 ~10 mg/kg
投与方法 Intraperitoneally
