Glutor

Glutor is a selective GLUT 1/2/3 inhibitor that can suppress glucose uptake. Glutor can inhibit glycolysis and has anti-tumor activity, inducing cell apoptosis.

Glutor reduced the uptake of 2-DG with similar efficacy in different cancer cell lines, such as HCT116 (IC50 = 10.8 nM), UM-UC-3 (IC50 = 8.3 nM), UO-31 (IC50 = 3.6 nM), and MIA PaCa-2 (IC50 = 1.1 nM)[1].Glutor effectively decreases glycolysis in HCT116 cells, thereby preventing the reduction of oxidative phosphorylation rates after glucose addition[1]. Glutor inhibits the proliferation of malignant cell lines without harming the growth of non-malignant peripheral blood mononuclear cells (PBMCs) and IMR-90 embryonic lung cells[1]. Glutor (0.5μM, 24-48h) suppresses the glucose uptake-induced upregulation of GLUT-1 and GLUT-3 expression[1]. Glutor (0.0001-1μM, 24h) inhibits the number of DL cells in a time- and dose-dependent manner, with an Glutor reduced the uptake of 2-DG with similar efficacy in different cancer cell lines, such as HCT116 (IC50 = 10.8 nM), UM-UC-3 (IC50 = 8.3 nM), UO-31 (IC50 = 3.6 nM), and MIA PaCa-2 (IC50 = 1.1 nM)[1].Glutor effectively decreases glycolysis in HCT116 cells, thereby preventing the reduction of oxidative phosphorylation rates after glucose addition[1].
