| Application: | GSK343 has been used: • as an inhibitor of enhancer of zeste homolog 2 (EZH2) to assess the impact of chromatin condensation on cell migration • as histone methyl transferase inhibitor, to suppress the Polyandrocarpa misakiensis, mitochondrial non-coding-region (NCR) PmNCR reporter gene expression, facilitated by TC14-3 • as a supplement in the growth medium to inhibit the generation of H3K27me3 or to inhibit RNA polymerase II • as EZH2 inhibitor to treat castration-resistant neuroendocrine prostate cancer (CRPC-NE) |
| Biochem/physiol Actions: | GSK343 is a potent, specific inhibitor of the histone H3-lysine 27 (H3K27) methyltransferase EZH2. |
| Biochem/physiol Actions: | GSK343 is a potent, specific inhibitor of the histone H3-lysine 27 (H3K27) methyltransferase EZH2. GSK343 inhibits EZH2 enzymatic activity with an IC50 of 4 nM. The compound displays 60 fold selectivity for EZH2 vs. EZH1, and 1000 fold or greater selectivity against other histone methyltransferases. The IC50 for inhibition of H3K27 methylation is < 200 nM in HCC1806 cells.
