<h2>What are epigenetics enzymes and inhibitors?</h2>
&nbsp;
Epigenetics enzymes and inhibitors are the molecular tools for directly studying or modulating the enzymatic machinery that writes, erases, or reads epigenetic marks. The major classes include: DNA methyltransferases (DNMT1, DNMT3A, DNMT3B), which catalyze the addition of a methyl group to cytosine; TET family enzymes (TET1, TET2, TET3), which oxidize 5-methylcytosine to 5-hydroxymethylcytosine; histone acetyltransferases (HATs) and histone deacetylases (HDACs), which add and remove acetyl groups from histone lysine residues; and histone methyltransferases (HMTs) including EZH2, DOT1L, and G9a. Small-molecule inhibitors of HDAC and DNMT enzymes are the most clinically and experimentally advanced of these tools.

<h2>How to choose epigenetics enzymes and inhibitors</h2>
&nbsp;
Choose DNMT inhibitors to globally reduce or deplete DNA methylation in cells
Nucleoside analog DNMT inhibitors like 5-azacytidine and decitabine incorporate into DNA and trap DNMT1, preventing maintenance methylation and causing passive demethylation through DNA replication, while newer non-nucleoside DNMT inhibitors are in development for more selective, non-genotoxic methylation reduction.
Choose HDAC inhibitors to globally increase histone acetylation
HDAC inhibitors including pan-HDAC hydroxamates like vorinostat (SAHA) or class-selective compounds reduce histone deacetylase activity and cause hyperacetylation of histone lysine residues, broadly promoting gene expression at silenced loci. HDAC inhibitors are the most clinically advanced class of epigenetic therapeutics, with multiple FDA-approved compounds.
Use TET enzyme preparations for in vitro 5-hmC oxidation studies
Purified TET1, TET2, or TET3 enzyme preparations allow controlled in vitro oxidation of 5-methylcytosine to 5-hydroxymethylcytosine and further oxidation products, useful for generating defined 5-hmC-containing substrate DNA or studying TET enzyme activity and selectivity.
Choose EZH2 or other HMT inhibitors for studying PRC2-dependent gene silencing
EZH2, the catalytic subunit of polycomb repressive complex 2 (PRC2), catalyzes H3K27 trimethylation (H3K27me3), a histone modification associated with repression of tumor suppressor genes, and EZH2 inhibitors like tazemetostat are used in research to probe the role of this silencing mark.
Combine inhibitors to study epistatic relationships between epigenetic marks
Because DNA methylation, histone acetylation, and histone methylation are mechanistically linked, combining HDAC inhibitors with DNMT inhibitors can produce synergistic effects on gene expression exceeding either alone, and these combination approaches are both experimental tools and the basis for combination epigenetic therapy research.

<h2>Specifications context</h2>
&nbsp;
HDAC and DNMT inhibitors are the most clinically advanced classes of epigenetic therapeutics, with multiple HDAC inhibitors including vorinostat and romidepsin approved for hematological malignancies, EZH2 inhibitors including tazemetostat having received accelerated approval, and multiple BET inhibitors in clinical trials. As of 2026, CRISPR/dCas9 systems fused with DNMTs, TETs, and HDACs enable locus-specific epigenome editing, extending classic enzyme and inhibitor approaches toward targeted epigenetic modulation.
