PFK-015 (PFK15) is an effective inhibitor of PFKFB3 (IC50: 110 nM) and inhibits PFKFB3 activity in Y cells (IC50: 20 nM).

PFKFB3:110 nM, PFKFB3:20 nM

Recombinant PFKFB3 assay: Kinase reactions are conducted by incubating 13 ng of recombinant human PFKFB3 protein in a reaction mix containing 10 μmol/L ATP, 10 μmol/L F6P, and either dimethyl sulfoxide (DMSO) vehicle control, 3PO, or PFK15 for 1 hour at room temperature. Kinase activity is measured with the Adapta Universal Kinase Assay per manufacturer

Viability is determined using trypan blue exclusion. Cells were incubated in 20% trypan blue for 5 minutes. Cells excluding trypan blue are counted using a standard hemocytometer to determine the total number of viable cells. Experiments are conducted in triplicate. (Only for Reference)
