Fasentin (392721-37-8) is a novel inhibitor of glucose uptake which acts via inhibition of the glucose transporter GluT1 and GluT4 (IC50=68 μM).1?Inhibition of glucose uptake is cell type specific2?and is a promising approach to new cancer therapeutics3. Rescues cardiac progenitor cell dysfunction and mitochondrial fission induced by high glucose.4?Sensitizes cells to FAS-induced cell death.5,6

Fasentin is a novel glucose transport inhibitor that blocks glucose uptake and is also a chemical sensitizer to the death receptor stimuli FAS and tumor necrosis factor apoptosis-inducing ligand.

Fasentin has been used as a glucose transporter (GLUT1) inhibitor to assess its effects on the vulnerability of a wide range of triple-negative breast cancer (TNBC) cell lines and to study its effects on cytotoxic drugs induced by hydrocortisone (HC).

Fasentin is a novel inhibitor of glucose uptake, GluT1 inhibitor. Fasentin is a novel inhibitor of glucose uptake that sensitizes cells to FAS-induced cell death. Fasentin selectively sensitized to death ligands, but did not decrease FLIP expression. It alters expression of genes associated with nutrient and glucose deprivation. Fasentin interacted with a unique site in the intracellular channel of the glucose transport protein GLUT1.
