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.

Purpose: Lacking effective targeted therapies, triple-negative breast cancer (TNBCs) is highly aggressive and metastatic disease, and remains clinically challenging breast cancer subtype to treat. Despite the survival dependency on the proteasome pathway genes, FDA-approved proteasome inhibitors induced minimal clinical response

EBV infection of preinvasive nasopharyngeal epithelium is believed to be an initiation step during pathogenesis of nasopharyngeal carcinoma (NPC), but the mechanisms remain poorly understood. Here we report a novel mechanism driving NPC metastasis through the EBV-encoded LMP1-mediated metabolic reprogramming
