BIX-01294 Trihydrochloride is a G9a-like protein and G9a histone lysine methyltransferase inhibitor with IC50 values of 0.7 and 1.7 μM respectively. BIX-01294 inhibits the G9aHMTase dependent levels of histone-3 lysine (9) methylation (H3K9me). BIX-01294 can also inhibit H3K9 Jumonji demethylase KIAA1718 with half-maximal inhibitory concentrations in low micromolar range. In its inhibition of the histone lysine methyltransferases, BIX 01294 does not compete with cofactor S-adenosyl-methionine. The target enzyme is G9a, and it selectively impairs G9a HMTase and the generation of H3K9me2 in vitro. BIX-01294 (4.1 μM) reduces H3K9me2 Levels in bulk histone preparations from wt ES cells, mouse embryonic fibroblasts and HeLa cells. BIX-01294 reduces H3K9me2 at Several G9a Target Genes including Bim1 and Serac1.

|---|---|
| Cell lines | MCF-7 cells |
| Preparation method | MCF-7 cells treated with 10 μM BIX were fixed in 4% glutaraldehyde. After dehydration, ultrathin sections were prepared using a Sorvall MT5000 microtome (DuPont Instruments, MT5000), and collected on 150 mesh copper grids. Sections were stained with 1% uranyl acetate and/or lead citrate, and images obtained with a JEOL 100CX transmission electron microscope (JEOL USA, JEOL-100CX). |

| WDR5-IN-4
WDR5-IN-4 is an inhibitor of the WIN site of chromatin-associated WD repeat-containing protein 5 (WDR5), with a Kd of 0.1 nM. WDR5-IN-4 displaces WDR5 from chromatin and decreases the expression of associated genes, causing translational inhibition, nucleolar stress. Anti-cancer activity. |
| CMP-5 dihydrochloride
CMP-5 dihydrochloride is a potent, specific, and selective PRMT5 inhibitor, while displays no activity against PRMT1, PRMT4, and PRMT7 enzymes. CMP-5 dihydrochloride selectively blocks S2Me-H4R3 by inhibiting PRMT5 methyltransferase activity on histone preparations. |
