PI-103 is a potent and selective inhibitor of class I PI3K, mTOR and DNA-PK with IC50 values of 2, 3, 3, 15, 30 and 23 nM for p110α, p110β, p110δ, p110γ, mTOR and DNA-PK, respectively [1].
PI-103 showed potent antiproliferation activities in various cancer cell lines such as prostate, ovary and glioblastoma. It exerted GI50 values of 0.14, 0.06, 0.13, 0.10, 0.12 and 0.08 μM in U87MG, IGROV-1, DETROIT-562, PC3, SKOV-3 and HUVEC cells, respectively. In U87MG cells, 2 hour-treatment of PI-103 caused inhibition effects on various phosphorylated protein biomarkers of PI3K pathway with IC50 values of 15, 36, 111, 106 and 105 nM for p-AKTSer473, p-AKTThr308, p-GSK3βSer9, p-p70S6KThr421/Ser424 and p-S6RPSer235/Ser236, respectively [1].

| Cell experiment: [1] | |
|
Cell lines |
A549 and H460 cells |
|
Preparation method |
The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months. |
|
Reaction Conditions |
72 hours, 2 μM for A549 cells 0.5 μM for H460 cells |
|
Applications |
Incubation of A549 cells with 2 μM PI-103 for 72 h induced an ~60% reduction in cell number. In contrast to A549 cells, H460 cells were highly sensitive to low-dose PI-103. Treatment of H460 cells with 0.5 μM PI-103 for 72 h resulted in ~60% inhibition. Results showed that exposure of A549 and H460 cells to PI-103 with the indicated concentrations for 72 h induced growth inhibition in a dose-dependent manner. |
| Animal experiment: [2] | |
|
Animal models |
FVB/N wild type mice injected with 37-31E-F3 cells |
|
Dosage form |
Intraperitoneal injection, 10 mg/kg, daily |
|
Applications |
PI-103 treatment promoted a significant in vivo tumor growth compared with the DMSO treated mice. It was effective by partially inhibiting the Akt and S6 ribosomal protein phosphorylation. Tumors from PI-103-treated mice showed higher levels of cyclin D1 and more proliferating cells as indicated by the number of Ki67 positive cells. PI-103-treated tumors had the lowest apoptotic rate. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
