CAS No. : 2183470-12-2
MCE 国际站:GCN2iB
产品活性:GCN2iB 是具有 ATP 竞争性的、一种丝氨酸/苏氨酸蛋白激酶 ——压力应答激酶 (GCN2) 的抑制剂,其 IC50 值为 2.4 nM。
研究领域:Cell Cycle/DNA Damage | Autophagy
作用靶点:Eukaryotic Initiation Factor (eIF) | Autophagy
In Vitro: GCN2iB shows an IC50 value of 2.4 nM for GCN2 and potent cellular activity. In a panel of 468 kinases, only GCN2 shows >99.5% inhibition, and three kinases (MAP2K5, STK10, and ZAK) show >95%inhibition at 1 μM GCN2iB, demonstrating high kinase selectivity.
In Vivo: In the antitumor activity study of the CCRF-CEM xenografts, ASNase or GCN2iB alone does not significantly affect tumor growth. Notably, a combination of ASNase and GCN2iB elicit potent antitumor activity (P=0.0002) with synergistic effects. In MV-4-11 and SU.86.86 xenografts, robust antitumor activity of the combination of GCN2iB and ASNase is observed with synergistic effect, respectively. ASNase/GCN2iB-treated tumors do not show significant growth even after drug cessation. The combination of ASNase and GCN2iB yield survival advantage compared with the vehicle treated control with synergistic effect.
