M2698 (0.3 nM-50 M) dose-dependently inhibits proliferation in breast tumor cell lines (IC50s: 0.02-8.5 µM). M2698 (0.3-1 µM) induces feedback loop phosphorylation on Akt and suppresses Akt and p70S6K activity in HCC1419 and MDA-MB-453 cells. M2698 inhibits indirectly pGSK3β and pS6 with IC50s of 17 and 15 nM[1].

Gavage administration of M2698 (10-30 mg/kg) dose-dependently inhibits the growth of tumors and increases pAkt levels in tumor tissue. M2698 (30 mg/kg) causes tumor regression. M2698 (1-20 mg/kg) inhibits S6 phosphorylation in a dose-proportional manner over time[1].
