Description: SGI-1027 is a potent DNMT inhibitor, which reactivates tumor suppressor genes by blocking DNA methyltransferase 1 activity and inducing its degradation. Treatment of different cancer cell lines with SGI-1027 resulted in selective degradation of DNMT1 with minimal or no effects on DNMT3A and DNMT3B. At a concentration of 2.5 to 5 micromol/L (similar to that of decitabine), complete degradation of DNMT1 protein was achieved within 24 h without significantly affecting its mRNA level. SGI-1027 may have the potential for use in epigenetic cancer therapy.
