KU-0060648 is a dual inhibitor of PI3K and DNA-PK with IC₅₀s of 4 nM, 0.5 nM, 0.1 nM, 0.594 nM and 8.6 nM for PI3Kα, PI3Kβ, PI3Kγ, PI3Kδ and DNA-PK, respectively^[1].

KU-0060648 inhibits cellular DNA-PK auto-phosphorylation with IC₅₀ values of 0.019 μM (MCF7 cells) and 0.17 μM (SW620 cells), and PI-3K-mediated AKT phosphorylation with IC₅₀ values of 0.039 μM (MCF7 cells) and >10 μM (SW620 cells)^[1].
KU-0060648 (30-500 nM; 72 hours) dose-dependently inhibits HepG2 cell proliferation, IC₅₀=134.32nM^[2].
KU-0060648 (0.1-1 μM；5 days) inhibits cell lines growth with GI₅₀s of 0.95 μM, 0.21 μM, 0.27 μM, 0.41 μM and 1 μM in SW620, LoVo, MCF7, T47D and MDA-MB-231 cells^[1].
KU-0060648 (100-300 nM;12 hours) significantly inhibits activation of PI3K (p85 phosphorylation), AKT (Ser-473 and Thr-308 phosphorylations) and mTOR (p70S6K1 Thr-389 phosphorylation) in HepG2/Huh-7 lines and primary human HCC cells^[2].

KU-0060648 (intraperitoneal injection; 10 and 50 mg/kg; once daily; daily for 21 days) dramatically inhibits HepG2 xenograft growth in nude mice, the tumor weights (at week 5) of KU-0060648 group mice are dramatically lighter than that of vehicle control mice and exert a dose-dependent effect in vivo^[1].
