GLS1 inhibitor is an inhibitor of glutaminase 1 (GLS1; IC = 0.021 μM). It inhibits the growth of NCI H1703 non-small cell lung cancer (NSCLC) cells in vitro (GI = 0.011 μM). GLS1 inhibitor (100 mg/kg) reduces tumor growth, increases tumor levels of glutamine, and decreases tumor levels of glutamate and aspartate in an NCI H1703 mouse xenograft model.
GLS1 Inhibitor is an orally active, allosteric, selective GLS1 inhibitor with an IC50 of 0.021 µM for GLS1 and an IC50 of 0.051 µM for the GLS1 GAC splice variant. GLS1 Inhibitor increases glutamine and decreases glutamate and aspartate. GLS1 Inhibitor exhibits anticancer activity against non-small cell lung cancer. GLS1 Inhibitor can be used for research on non-small cell lung cancer.

体内研究
GLS1 Inhibitor (100 mg/kg; oral; Once a day; 21 days) was effective in the NCI-H1703 SCID mouse xenograft model, producing 37% tumor growth inhibition by day 21 and reaching a maximum of 73% by day 12, accompanied by changes in tumor glutamine, glutamate, and aspartate biomarkers.
