PFKFB3 Inhibitor III, YN1

A cell-permeable isoflavone compound that acts as a potent and competitive inhibitor of fructose-2,6-bisphosphatase 3 (PFKFB3; IC₅₀ = 670 nM; K_i = 240 nM). Directly docks into the Fru-6-P binding pocket of PFKFB3 and down-regulates Fru-2,6-BP levels (40% decrease in 48 h in HeLa cells) resulting in reduced glycolysis and lactate production. Shown to diminish the proliferation of HCT-116 human adenocarcinoma cells (GI₅₀ = 8.2 µM) and inhibit HeLa cells colony formation on soft agar (~79% reduction at 25 µM). Induces apoptotic (~25 µM) and necrotic (~50 µM) cell death depending on the level of ATP depletion. Also reported to increase autophagy in HCT-116 cells as evidenced by an increase in LC3-II levels and a decrease in p62 levels.

Please note that the molecular weight for this compound is batch-specific due to variable water content.
