一种有效的 I 类 PI3K/mTOR 双抑制剂，p110α/β/δ/γ 的 IC50 分别为 2/3/3/15/。

A potent, dual class I PI3K/mTOR inhibitor with IC50 of 2/3/3/15/ for p110α/β/δ/γ, respectively; also inhibits TORC1 (>80% inhibition at 0.5 uM) and DNA-PK (IC50=14 nM), 15- to 20-fold less activity against class II PI3K C2β (IC50=43 nM), >1,300-fold selectivity over the class III PI3K Vsp34; potently inhibits proliferation and invasion of a wide variety of human cancer cells in vitro; shows activity in cancer xenograft models.

PI-103 exhibits antiproliferative properties in a panel of human cancer cell lines. PI-103 is essentially cytostatic for cell lines and induced cell cycle arrest in the G1 phase. In blast cells, PI-103 inhibits leukemic proliferation, the clonogenicity of leukemic progenitors and induces mitochondrial apoptosis, especially in the compartment containing leukemic stem cells . PI-103 potently inhibits both the rapamycin-sensitive (mTORC1, IC50=20 nM) and rapamycin-insensitive (mTORC2, IC50=83 nM) complexes of the protein kinase mTOR.

PI-103 shows therapeutic activity against a range of human tumor xenografts, exhibiting inhibition of angiogenesis, invasion, and metastasis, as well as direct antiproliferative effects. PI-103 induces immunosuppression promoting in vivo tumor growth and inhibiting apoptosis. Tumors from PI-103-treated mice shows higher levels of cyclin D1 and more proliferating cells.
