Ordering Information

Biological Activity

KAN0438757 is a potent inhibitor of the metabolic kinase PFKFB3 that exhibits selectivity over PFKFB4. By target-specific suppression of PFKFB3, the compound decreases intracellular fructose-2,6-bisphosphate production and inhibits glycolytic flux in cancer cells. Downstream, PFKFB3 inhibition impairs homologous recombination repair of DNA double-strand breaks, promoting apoptotic cell death and sensitizing malignant cells to ionizing radiation. [1]

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
