Hypothesis
Can a new inhibitor be identified for PFKFB2 kinase activity?
Conclusion
A new inhibitor, B2, was identified that effectively inhibits PFKFB2 and alters glycolytic activity in cells.
Supporting Evidence
- B2 inhibits PFKFB2 with an IC50 of 3.29 μM.
- B2 also inhibits PFKFB3 with an IC50 of 11.89 μM.
- B2 treatment decreased fructose-1,6-bisphosphate levels in A-498 cells.
- B2 increased fructose-6-phosphate levels, indicating an inhibitory effect on PFK-1 activity.
Takeaway
Scientists found a new substance that stops a specific enzyme from working, which could help in treating diseases like cancer.
Methodology
Recombinant PFKFB2 was expressed and an enzymatic assay was developed to test a library of molecules for inhibition.
