| Abstract: | Tumor cells usually show abnormally high glycolysis rate to maintain the dynamic balance of energy. The growth of tumor cells can be affected by inhibiting the activity of pyruvate kinase (especially M2-type isozyme, PKM2), the rate limiting enzyme of glycolysis. This is helpful to the treatment of tumor. Herein, metal organic frameworks (MOFs) were found to inhibit the activity of PKM2. Nanoscale ZIF-8 was synthesized by standing and ultrasonic method, respectively. The ZIF-8 has the performance of inhibiting PKM2. Further research showed that the inhibition ability was attributed to zinc ion in ZIF-8. Interestingly, the IC50 of ZIF-8 on PKM2 was one percent of that of zinc ion. This novel enzyme inhibitor is expected to be used in cancer therapy. |
