EED-IN-5 is an orally active, EZH2-selective trisubstituted pyridine-based EED-H3K27me3 inhibitor and immunomodulator with anti-inflammatory activity. The IC50 value of EED-IN-5 against EED is 28.21 nM. In mouse models, EED-IN-5 preferentially and persistently accumulates in lymph nodes after oral administration. By reducing the H3K27me3 level of dendritic cells and inhibiting their migration, EED-IN-5 decreases the infiltration of specific dendritic cells, macrophages and T cells into the spinal cord and brain. EED-IN-5 exhibits hERG inhibitory activity, shows negative results in the Mini-Ames test, and causes no obvious toxicity upon long-term high-dose administration. EED-IN-5 can be used for the research of multiple sclerosis.
