Azacitidine, similar to decitabine, is a cytidine analogue functioning as a Dnmt inhibitor. Through its incorporation into replicating DNA, azacitidine forms adducts with Dnmt3b, leading to its degradation. This direct inhibition results in reduced Dnmt3b activity, disrupting DNA methylation patterns.

RG108 is a small-molecule inhibitor designed to target Dnmt enzymes, including Dnmt3b. Through binding to the catalytic domain of Dnmt3b, RG108 interferes with its enzymatic activity, resulting in the inhibition of DNA methylation. This direct inhibition disrupts Dnmt3b-mediated processes involved in epigenetic regulation.

Zebularine is a cytidine analogue and Dnmt inhibitor that inhibits both Dnmt1 and Dnmt3b. Through its incorporation into DNA, zebularine forms covalent adducts with Dnmt3b, leading to its degradation.

Psammaplin A is a natural marine compound identified as a Dnmt inhibitor, including Dnmt3b. Through direct binding to the catalytic domain of Dnmt3b, psammaplin A interferes with its enzymatic activity, leading to the inhibition of DNA methylation. This direct inhibition disrupts Dnmt3b-mediated processes involved in epigenetic regulation.

BIX-01294 is a small-molecule inhibitor that specifically targets Dnmt3b. By binding to the catalytic domain of Dnmt3b, BIX-01294 interferes with its enzymatic activity, leading to the inhibition of DNA methylation.
