Lysine-specific demethylase inhibitor (1C) (LSD inhibitor (1C)) is an inhibitor of LSD1, a repressive demethylase selective for histone H3 lysine 4 (H3K4).1,2LSD inhibitor (1C) inhibits LSD1 activity by 85.9% when used at a concentration of 10 μM.1It increases the level of H3K4 methylation, including H3K4me1 and H3K4me2 but not H3K9me2 levels, in HCT116 human colon carcinoma cells.2LSD inhibitor (1C) also induces re-expression of the Wnt signaling pathway proteins secreted frizzle-related protein 1 (SFRP1), SFRP4, and SFRP5, as well as the transcription factor GATA5, which are aberrantly silenced in HCT116 cells.

MM-401 (TFA), an MLL1 H3K4 methyltransferase inhibitor, effectively impedes MLL1 activity (IC 50 = 0.32 µM) by preventing MLL1-WDR5 interaction. It can induce cell cycle arrest, apoptosis, and differentiation, offering potential for MLL leukemia research [1].

KDOAM-25, a potent and highly selective inhibitor of histone lysine demethylases 5 (KDM5) with IC50 values of 71 nM for KDM5A, 19 nM for KDM5B, 69 nM for KDM5C, and 69 nM for KDM5D, enhances global H3K4 methylation at transcriptional start sites and reduces proliferation in multiple myeloma MM1S cells.

T-448 free base is a specific, orally active and irreversible lysine-specific demethylase 1 (LSD1, an H3K4 demethylase) inhibitor(IC50 of 22 nM).

KDOAM-25 trihydrochloride is a potent and highly selective inhibitor of histone lysine demethylase 5 (KDM5), acting on KDM5A (IC50: 71 nM), KDM5B (IC50: 19 nM), KDM5C (IC50: 69 nM), KDM5D (IC50: 69 nM). KDOAM-25 trihydrochloride enhances overall H3K4 methylation at the transcription start site and hinders the proliferation of multiple myeloma MM1S cells.

WDR5-0102 is a compound that inhibits the WDR5-MLL1 interface (K dis = 7 μM, K d = 4 μM), selectively reducing MLL1 HMT activity without affecting the human H3K4 methyltransferase SETD7 or other HMTs, including G9a, EHMT1, SUV39H2, SETD8, PRMT3, and PRMT5.

CPI-455 is a specific KDM5 inhibitor with IC50 value of 10 ± 1 nM for full-length KDM5A in enzymatic assays, elevating global levels of H3K4 trimethylation (H3K4me3) and decreased the number of DTPs in multiple cancer cell line models treated with target

INCB059872, also known as INCB59872, is a potent, selective, and orally active lysine-specific demethylase 1 inhibitor. INCB059872 binds to and inhibits LSD1, a demethylase that suppresses the expression of target genes by converting the di- and mono-methylated forms of lysine at position 4 of histone H3 (H3K4) to mono- and unmethylated H3K4, respectively, through amine oxidation. LSD1 inhibition enhances H3K4 methylation and increases the expression of tumor-suppressor genes. In addition, LSD1 demethylates mono- or di-methylated H3K9 which increases gene expression of tumor promoting genes; inhibition of LSD1 promotes H3K9 methylation and decreases transcription of these genes.
