Biological Activity of SGI-1027


SGI-1027 is a potent and selective inhibitor of DNA methyltransferase (DNMT) with IC50 of 6, 8, 7.5 μM for DNMT1, DNMT3A, and DNMT3B, respectively.
IC50 value: 6/8/7.5 uM (DNMT1/3A/3B) [1]
Target: DNMT1/3A/3B
SGI-1027, inhibits the activity of DNMT1, DNMT3A, and DNMT3B as well M. SssI with comparable IC(50) (6-13 micromol/L) by competing with S-adenosylmethionine in the methylation reaction. 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 [1].
