PI-103 is a dual inhibitor of PI3K/Akt and mTOR with IC50 value of 0.002 μM , 0.003μM, 0.003μM, 0.015μM, 0.030μM for P110α, P110β, P110γ, P110 and mTOR, respectively .
PI3K/AKT/mTOR pathway is an intracellular signaling pathway and plays an important role in regulating cell cycle. It has been shown that PI3K/AKT/MTOR pathway is directly related to cellular quiescence, proliferation, cancer, and longevity. And many studies have shown that activation of the PI3K/Akt signaling pathway is correlated with poor prognosis in a variety of cancers which demonstrated that inhibition of the pathway may be regarded as a promising therapy [2, 3].
PI-103 is a selective PI3K/Akt and mTORC1 inhibitor. When tested with leukemic cell lines (MOLM14, OCI-AML3 and MV4-11) with activation of PI3K/Akt, mTORC1 and ERK/MAPK signaling pathways, PI-103 blocked cells proliferation via inhibiting PI3K/Akt and mTORC1 activity in a concentration of 1μM . In HCC cell line--Huh7 cells, treated PI-103 alone or combined with sorafenib inhibited cells proliferation in a dose-dependent manner through inhibition of PI3K/Akt and mTORC1 pathways . When tested with U87MG glioblastoma cells, PI-103 treatment in 30 nM/L showed significant inhibition of PI3K/Akt and mTORC1 phosphorylation . In neuroblastoma cell lines SK-N-BE (2), IMR-32 with amplified MYCN, PI-103 inhibited cell growth in a time- and concentration-dependent manner via inhibiting PI3K/Akt and mTORC1 activity .
In SK-N-BE (2) with MYCN-mutant xenografted nude mice model, treated PI-103 intraperitoneally (10 mg/kg) markedly reduced the tumor volume index and tumor weight via inhibiting PI3K/ mTOR pathways .
