| Bioactivity | PI-103 Hydrochloride is a dual PI3K and mTOR inhibitor with IC50s of 8 nM, 88 nM, 48 nM, 150 nM, 20 nM, and 83 nM for p110α, p110β, p110δ, p110γ, mTORC1, and mTORC2. PI-103 Hydrochloride also inhibits DNA-PK with an IC50 of 2 nM. PI-103 Hydrochloride induces autophagy[1][2][3][4]. |
| Invitro | PI-103 exhibits antiproliferative properties in a panel of human cancer cell lines[1]. 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 [2]. 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[4]. |
