Application

STF-31 has been used in glucose transporter 1 (GLUT1) inhibition.

Biochem/physiol Actions

STF-31 selectively inhibits the glucose transporter GLUT1 and selectively impairs cancer cell growth of kidney and other types of cancer cells that lack the von Hippel-Lindau (VHL) tumor suppressor protein. Inactivation of VHL increases the activity of hypoxia-inducible factor transcription factor HIF, which in turn stimulates the transcription of genes involved in glucose metabolism, including the GLUT1 gene. VHL-deficient cancer cells, which include about 80% of renal cell carcinomas, are dependent on the high affinity GLUT1 transporter and aerobic glycolysis for ATP production. STF-31 binds directly to the GLUT1 transporter, blocking glucose uptake, resulting in necrosis in VHL-deficient cancer cells, but not in normal cells or cancer cells with intact VHL.
STF-31 selectively inhibits the glucose transporter GLUT1.
