MS2177 is a potent and selective inhibitor of SETD8, the only methyltransferase known to catalyze monomethylation of histoneH4 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
CAY10669 is an inhibitor of the histone acetyltransferase PCAF (p300 CREB-binding protein-associated factor; IC50 = 662 μM), displaying a 2-fold improvement in inhibitory potency over anacardic acid . At 30-60 μM, CAY10669 can dose-dependently inhibit histoneH4 acetylation in HepG2 cells in vitro.
Trichostatin C is a glycosylated derivative of trichostatin A , the antifungal antibiotic that reversibly inhibits histone deacetylase. Trichostatin C is reported to be the first example of a glucopyranosyl hydroxamate identified in nature. It has been shown to induce the differentiation of a mouse erythroleukemia cell line and to increase histoneH4 acetylation in B cells, though at higher concentrations than trichostatin A.
Amredobresib is a potent BET inhibitor that impedes the interaction between bromodomains and acetylated lysines on histone H3 and H4, thereby serving as crucial regulators of gene transcription. It proves valuable in the investigation of acute myeloid leukemia (AML) and cancer.
