Bisubstrate inhibitor 78 is an inhibitor of nicotinamide N-methyltransferase (NNMT; IC50= 1.41 μM).1It binds the NNMT active site in the binding pockets for the NNMT substrates S-adenosyl-L-methionine (SAM) and nicotinamide . Bisubstrate inhibitor 78 is selective for NNMT over histone-lysine N-methytransferase NSD2 and protein arginine methyltransferase 1 (PRMT1; IC50s = >50 μM for both). It reduces levels of 1-methylnicotinamide in, and inhibits proliferation of, HSC-2 oral cancer cells when used at a concentration of 100 μM.This compound is unstable in powder form and other related salt forms are recommended.

GSK-A is a Histone Lysine Methyltransferase EZH2 inhibitor.

MS2177 is a potent and selective inhibitor of SETD8, the only methyltransferase known to catalyze monomethylation of histone H4 lysine 20 (H4K20). MS2177 has an in vitro IC50 of 1.9 μM (σ = 1.05 μM, n = 4) in ascintillation proximity assay. Binding of MS2

The methylation of lysine residues on histones plays a central role in determining euchromatin structure and gene expression. The histone methyltransferase (HMTase) G9a can mono- or dimethylate lysine 9 on histone 3 (H3), contributing to early embryogenesis, genomic imprinting, and lymphocyte development. BIX01294 (hydrochloride hydrate) is a selective inhibitor of G9a HMTase (IC50 = 1.7 μM). It less effectively inhibits the HMTase G9a-like protein (GLP; IC50 = 38 μM) and has no effect on other known HMTases. BIX01294 has been used in combination with the calcium channel activator BayK8644 to facilitate the generation of induced pluripotent stem cells from somatic cells in vitro.

Histone H3 (21-44)-GK-biotin is a peptide fragment of histone H3 that corresponds to amino acid residues 22-45 of the human histone H3.1 and 3.2 sequences and is biotinylated via a C-terminal GK linker. Histone H3 (21-44) contains a lysine residue at position 23 that is subject to acetylation, an arginine at position 26 subject to methylation, and a serine at position 28 subject to phosphorylation, as well as lysine residues at positions 27 and 36 that are subject to methylation and acetylation. Histone H3 (21-44)-GK-biotin has been used as a substrate for the primate-specific histone methyltransferase PR domain-containing protein 7 (PRDM7) to determine substrate specificity.

Histone H3 (1-21) is a truncated form of the Histone H3 protein consisting of amino acids 1 to 21. It serves as a common substrate for methyltransferase assays targeting Histone 3 at lysine 4 and lysine 9, as well as for acetyltransferase assays targeting Histone 3 at lysine 9 and lysine 14.

PFI-2 hydrochloride ((R)-PFI-2 hydrochloride) 是一种有效的、高度选择性的、具有细胞活性的 SETD7 甲基转移酶抑制剂，IC50值为2nM，活性是 (S)-PFI-2 的 500 倍。

TC-5115 is a potent inhibitor of MLL methyltransferase with IC50 value of 16 nM. TC-5115 may lead to the development of a new therapy for the treatment of human MLL leukemia. The mixed-lineage leukemia (MLL) protein, also known as MLL1, is a lysine methyltransferase specifically responsible for methylation of histone 3 lysine 4. MLL has been pursued as an attractive therapeutic target for the treatment of acute leukemia carrying the MLL fusion gene or MLL leukemia.
