Histone H3K9me3 (1-15) (H3(1-15)K9me3) TFA is used as a substrate. This post-translational modification (PTM) of histone H3K9me3 is indicative of heterochromatin surrounding the centromere.

SIRT6-IN-5(SIRT6 inhibitor 5) is a potent and selective SIRT6 inhibitor with an IC50 value of 34 μM.SIRT6-IN-5 is immunosuppressive and chemo-sensitizing, increases H3K9 acetylation and glucose uptake in cultured cells, and reduces T-cell proliferation.

BRD6688 is a selective HDAC2 inhibitor that acts by enhancing the learning and memory processes

E67-2, a derivative of E67, is a low-toxicity, selective inhibitor of the KIAA1718 Jumonji domain. It has an IC 50 value of 3.4 μM. E67-2 specifically inhibits the Jumonji demethylase for histone H3 lysine 9 (H3K9) and histone H3 lysine 4 (H3K4) demethylase.

S2157, a potent N-alkylated tranylcypromine (TCP) derivative lysine-specific demethylase 1 (LSD1) inhibitor, enhances H3K9 methylation and concurrently reduces H3K27 acetylation at super-enhancer sites. This compound triggers apoptosis in TCP-resistant T-cell acute lymphoblastic leukemia (T-ALL) cells by inhibiting NOTCH3 and TAL1 gene expression. Moreover, S2157 is capable of crossing the blood-brain barrier, effectively eliminating central nervous system (CNS) leukemia in mice models implanted with T-ALL cells.

S2116 is a powerful inhibitor of lysine-specific demethylase 1 (LSD1), and it is a derivative of N-alkylated tranylcypromine (TCP). S2116 exhibits its inhibitory effects by increasing H3K9 methylation and inducing reciprocal H3K27 deacetylation at super-enhancer regions. In TCP-resistant T-cell acute lymphoblastic leukemia (T-ALL) cells, S2116 triggers apoptosis by repressing the transcription of NOTCH3 and TAL1 genes. Furthermore, S2116 demonstrates significant growth retardation of T-ALL cells when xenotransplanted into mice.

Bomedemstat (IMG-7289) hydrochloride is an orally active, irreversible inhibitor of lysine-specific demethylase 1 (LSD1), exhibiting anticancer effects by inhibiting cancer cell proliferation and inducing apoptosis.

HDAC1/6-IN-1 is a potent multi-target inhibitor of GLP (IC50: 1.3 nM), HDAC6 (IC50: 13 nM) and HDAC1 (IC50: 89 nM). HDAC1/6-IN-1 inhibits the methylation and deacetylation of H3K9 at the protein level. HDAC1/6-IN-1 can block the cell cycle of cancer cells in G0/G1 phase, induce apoptosis and prevent cancer cell migration and invasion.

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.

BML-278 is a SIRT1 activator with an EC150 of 1 μM. It increases H3K9 methylation and inhibits H3K9 acetylation in parental and maternal prokaryotes, improving early embryonic development. BML-278 induces cell cycle arrest at the G1/S phase in primary human mesenchymal stromal cells, delaying senescence. It also reduces microtubule protein acetylation in U937 cells and increases mitochondrial density in mouse C2C12 myoblasts.

Compound A5b, also known as JMJD3/HDAC-IN-1, is a dual inhibitor that targets both JMJD3 (Jumonji domain-containing protein demethylase 3) and HADC1 (histone deacetylase, IC50 = 16 nM). It induces hypermethylation of histone H3K27 and hyperacetylation of H3K9, while also promoting apoptosis through the cleavage of caspase-7 and PARP. This compound has demonstrated the ability to effectively inhibit cancer cell cloning, migration, and invasion [1].

HDAC3-IN-2 (compound 4i), a pyrazinyl hydrazide-based HDAC3 inhibitor with an IC50 of 14 nM, effectively targets triple-negative breast cancer cells. Demonstrating cytotoxic activity, HDAC3-IN-2 exhibits an IC50 of 0.55 μM against 4T1 cells and 0.74 μM against MDA-MB-231 cells. In vivo, it shows anti-tumor efficacy in tumor-bearing mouse models by selectively elevating acetylation of histones H3K9, H3K27, and H4K12, enhancing apoptosis-inducing proteins caspase-3, caspase-7, and cytochrome c, and diminishing proliferation markers Bcl-2, CD44, EGFR, and Ki-67 [1].
