GCN2-IN-6 (Compound 6d) is a potent, and orally available GCN2 inhibitor confirmed by in-house enzymatic (IC₅₀ of 1.8 nM) and cellular assays (IC₅₀ of 9.3 nM). GCN2-IN-6 is also a eIF2α kinase PERK inhibitor with an IC₅₀ of 0.26 nM (in enzymatic assay) and 230 nM (in cells)^[1].

IC50: 1.8 nM (GCN2, in-house enzymatic) and 9.3 nM (GCN2, cellular assays); 0.26 nM (PERK, in-house enzymatic) and 230 nM (PERK, cellular assays)^[1]

To examine the impact of GCN2 inhibition on cancer cell proliferation, acute lymphoblastic leukemia (ALL) CCRFCEM cells are treated with GCN2-IN-6 (Compound 6d) in the presence of asparaginedepleting agent asparaginase. Treatment with GCN2-IN-6 greatly sensitizes CCRF-CEM cells to asparaginase. The moderate antiproliferative effects achieved by combining asparaginase and GCN2-IN-6 treatment are observed in GCN2-wildtype (WT) mouse embryonic fibroblast (MEF) cells but not in GCN2-knockout (KO) MEF. GCN2-IN-6 demonstrates suppression on p-GCN2, p-eIF2α, and ATF4 activated by asparaginase^[1].

GCN2-IN-6 (Compound 6d; 0.3-3 mg/kg; oral administration; for 8 hours; mice) treatment at 3 mg/kg suppresses both self-phosphorylation of GCN2 and the downstream effector ATF4 to the basal level following pretreatment with asparaginase^[1].
