Z9 is a potent inhibitor of PFKFB3, a member of 6-phosphofructo-2-kinases family. It avidly competes with fructose 6-phosphate (F6P) at PFKFB3. YZ9 is also cell permeable, inhibiting the growth of HeLa cells.
YZ9 is a 5, 6, 7, 8-tetrahydroxy-2-(4-hydroxyphenyl) chromen-4-one (N4A) inhibitor.', 'YZ9 is a potent inhibitor of PFKFB3 (6-phosphfructo-2-kinase/fructose-2,6-bisphosphatase) with an IC50 = 183 nM. PFKFB3 is over expressed in many cancers and catalyzes the production of fructose-2,6-bisphosphate, which can potentiate PFK1 activity, enhancing glycolysis in tumor cells. YZ9 dose dependently inhibits proliferation of HeLa cells.
