Biological Activity

Description GCN2iB is an ATP-competitive serine/threonine-protein kinase general control nonderepressible 2 (GCN2) inhibitor with IC50 of 2.4 nM.
Targets
GCN2 [1]
(Cell-free assay)
2.4 nM
In vitro
In vitro

The treatment of acute lymphoblastic leukemia (ALL) cells with GCN2iB renders ALL cells sensitive to ASNase by preventing the induction of ASNS, resulting in reduced levels of de novo protein synthesis. Combined treatment with ASNase and GCN2iB induces the stress-activated MAPK pathway, thereby triggering apoptosis. By using cell-panel analyses, we also shows that acute myelogenous leukemia and pancreatic cancer cells are highly sensitive to the combined treatment. [1]
Kinase Assay GCN2 kinase assay
Recombinant GCN2 (1 nmol/L) protein is pre-incubated with GCN2 inhibitors for 60 min and then incubated with ATP (KM value of GCN2 = 190 μmol/L) and the green fluorescent protein-eIF2α substrate (130 nmol/L) at 25°C. The amount of phosphorylated substrate is determined using the LanthaScreen Tb-anti-p-eIF2α (pSer52) antibody kit. The IC50 value of eIF2α kinase is measured using the XLfit software.
Cell Research Cell lines Pancreatic cancer cells, CCRF-CEM cells, MEF cells (GCN2-WT or -KO), CCRF-CEM, MV-4-11, SU.86.86 cells
Concentrations 37 nM, 110 nM, 330 nM, 1.0 μM
Incubation Time 4 h, 72 h
Method

CCRF-CEM cells are treated with GCN2iB as indicated for 4 h. Cell lysates are analyzed by western blot; MEF cells (GCN2-WT or -KO) are treated with GCN2 inhibitors as indicated for 72 h. Cell viability is measured; CCRF-CEM, MV-4-11, and SU.86.86 cells are treated with 1 μmol/L GCN2iB as indicated for 72 h. Cell viability is measured at day 0 and day 3; CCRF-CEM and SU.86.86 cells are treated with GCN2 inhibitors as indicated for 72 h. Cell viability is measured.
In Vivo
In vivo

The combination of ASNase treatment with GCN2iB synergistically blocks in vivo tumor growth in ALL, AML, and pancreatic xenograft models. [1]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
