PI-103 Chemical Properties,Usage,Production

Description

PI-103 (371935-74-9) is a potent inhibitor of PI-3 kinase, mTOR and DNA-PK, IC50 = 8, 88, 150, 48,? 20, 83 and 2 nM for p110α, p110?, p110γ, p110δ, mTORC1, mTORC2 and DNA-PK respectively.1,2 Synergizes with arsenic disulfide to eradicate AML stem cells by induction of differentiation.3 Inhibits the growth of gefitinib-resistant non-small cell lung cancer cell lines.4 Induces autophagy in drug-resistant glioma.5 Protects against a-synuclein-induced toxicity in human neurons by induction of macroautophagy.6

Uses

PI 103 is a dual inhbitor of Class IA phosphatidylinositol 3-kinase and mammalian target of rapaymycin complex 1 (mTORC1), both of which are involved in pathways often activated in myelogenous leukemia. PI 103 also functions to enhance tumour radiosensitivity.

Definition

ChEBI: An organic heterotricyclic compound that is pyrido[3',2':4,5]furo[3,2-d]pyrimidine substituted at positions 2 and 4 by 3-hydroxyphenyl and morpholin-4-yl groups respectively. A dual-kinase inhibitor with anti-cancer properties.

General Description

A cell-permeable pyridinylfuranopyrimidine compound that acts as a potent and ATP-competitive inhibitor of DNA-PK, PI3-K, and mTOR (IC₅₀ = 2, 8, 88, 48, 150, 26, 20, and 83 nM for DNA-PK, p110α, p110β, p110δ, p110γ, PI3-KC2β, mTORC1, and mTORC2, respectively). It inhibits ATR and ATM only at much higher concentrations (IC₅₀ = 850 and 920 nM, respectively) and exhibits little activity towards a panel of more than 40 other kinases even at concentrations as high as 10 μM. Shown to effectively block PI3-K/Akt signaling and cell proliferation in glioma cell lines both in vitro and in vivo. A 10 mM (2 mg/574 μl) solution of PI-103 (Cat. No. 528101) in DMSO is also available.

Biological Activity

Inhibitor of DNA-PK, PI 3-kinase (p110 α ) and mTOR (IC 50 values are 2, 8, 20, 26, 48, 83, 88, 150, 850, 920, ~ 1000 and 2300 nM for DNA-PK, p110 α , mTORC1, PI3KC2 β , p110 δ , mTORC2, p110 β , p110 γ , ATR, ATM, PI3KC2 α and hsVPS34 respectively). Inhibits growth of human tumor xenografts in mice in vivo .
