体外研究
M2698 (0.3 nM to 50 M; 72 hours) inhibits proliferation in a dose-dependent manner in breast tumors cell lines with IC50s of 0.02-8.5 µM.
M2698 (0.3, 1 µM; 24 hours) inhibits p70S6K activity and induces feedback loop phosphorylation on Akt and suppresses Akt activity in breast cancer cell lines.
M2698 inhibits indirectly pGSK3β (IC50=17 nM) and pS6 (IC50=15 nM).

体内研究
M2698 (10-30 mg/kg/day; PO; 28 days) results in dose-dependent inhibition of tumor growth and results in tumor regression with the highest dose of 30 mg/kg.
M2698 (20 mg/kg/day; PO; 4 days) has a tumor:plasma exposure ratio of 12:1 over 24 hours and leads to increased levels of pAkt in tumor tissue.
The mean total concentration of M2698 after 16-hour infusion in rats is 1750 ng/g and 175 ng/mL in brain and plasma, respectively.
M2698 (po; 1, 5, 10, or 20 mg/kg/day; for 7 days) inhibits the phosphorylation of S6 in a dose-proportional manner over time after a single administration or daily treatments over 7 days.
Animal Model:
Female nude mice bearing MDA-MB-468 tumors
Dosage:
