5−Fluoro−2'−deoxycytidine is a DNMT inhibitor which forms covalent links with the cysteine residue in the DNMT active site.

SU11274 is a selective Met inhibitor with IC50 of 10 nM, no effects on PGDFRβ, EGFR or Tie2.

γ-Oryzanol is a phytochemical with membrane antioxidant, naturally occurring in crude rice bran oil, can be used to treat hyperlipidemia, disorders of menopause and to increase the muscle mass.

DC_05 is a non-nucleoside DNMT1 inhibitor (IC50=10.3 μM) with low micromolar IC50 values and significant selectivity toward other AdoMet-dependent protein methyltransferases.

Zebularine is a DNA methylation inhibitor which forms a covalent complex with DNA methyltransferases, it also inhibits cytidinedeaminase with Ki of 2 μM.

Decitabine is a potent inhibitor of DNA methyltransferase with IC50 of 438 nM and 4.38 nM in HL-60 and KG1a cells, respectively.

6-Thioguanine belongs to the thiopurine family of drugs that also include mercaptopurine and azathioprine, which are examples of antimetabolites, and is a purine analogue of the nucleobase guanine. It was found to inhibit SARS-CoV PLpro. 6-Thioguanine disrupts cytosine methylation by DNA methyltransferases in vitro and acts as a DNA demethylating agent in vivo.
