PP2(AGL 1879) 是可逆的ATP竞争性的Src家族抑制剂,对p56lck,p59fynT,Hck和Src的IC50分别为4,5,5和100 nM。An effective and selective inhibitor of Src family kinases
Information
PP2 PP2 (AG 1879, AGL 1879), a Src family kinase inhibitor, potently inhibits Lck/Fyn with IC50 of 4 nM/5 nM in cell-free assays, ~100-fold less potent to EGFR, inactive for ZAP-70, JAK2 and PKA.
In vitro
PP2 inhibits Src by binding to an area of the molecule that does not overlap with the ATP binding domain. PP2 (20 μM) induces 40-50% growth inhibition of HT29 cells, this concentration reduces the Src activity as early as 1 hour and maintains a 35% inhibition of Src activity for 2 days. PP2 (100 mM) decreases the Src activity of HT29 cells in a dose-dependent manner. PP2 (1 mM-100 mM) causes a dose-dependent growth inhibition of human colon cancer cells (HT29, SW480, and PMCO1), liver cancer cells (PLC/PRF/5, KYN-2, Li7, and HepG2), and breast cancer cells (MCF-7, MDA-MB-468, and BT-474). PP2 (20 μM) significantly increases aggregation in most of the cancer cells (HT29, SW480, PMCO1, PLC/PRF/5, KYN-2, Li7, MCF-7, and MDA-MB-468) in E-cadherin dependent manner. PP2 (20 μM) enhances E-cadherin expression and also strongly increases E-cadherin’s association with the actin cytoskeleton in cancer cells. PP2 (20 μM) increases the expression of α-catenin, β-catenin, and γ-catenin in HT29 cells, whereas in PLC/PRF/5 and MCF-7 cells, the total protein level of α-catenin does not change, but the levels of β- catenin and γ-catenin increases slightly. PP2 inhibits proliferation of two cervical cancer cells (HeLa and SiHa) in a time- and dose-dependent manner. PP2 (10 μM) down-regulates pSrc-Y416, pEGFR-Y845, and -Y1173 expression levels in HeLa and SiHa cells. PP2 (10 μM) could modulate cell cycle arrest by up-regulating p21(Cip1) and p27(Kip1) in both HeLa and SiHa cells and down-regulating expression of cyclin A, and cyclin dependent kinase-2, -4 (Cdk-2, -4) in HeLa and of cyclin B and Cdk-2 in SiHa.
In vivo
PP2 (5 mg/kg/day) induces some slowing in the growth rate of the primary tumors relative to the control treated with vehicle in SCID mice inoculated HT29 cells in the spleen. PP2 (5 mg/kg/day) induces some slowing in the growth rate of the primary tumors relative to the control treated with vehicle in SCID mice inoculated HT29 cells in the spleen. PP2 (5 mg/kg/day) significantly reduces the relative liver weight and liver metastasis volume compared with the controls in SCID mice inoculated HT29 cells in the spleen. PP2 (1.5 mg/kg i.p.) treated rats show approximately 50% reduction of infarct size on T2-weighted MRI and in TTC staining compared with controls in rats with focal ischemic brain injury. PP2 (1.5 mg/kg i.p.) results in better the neurological score than controls in rats with focal ischemic brain injury.
