Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: The compound (from a pre-print) is selective KDM5 covalent inhibitor designed to target cysteine residues only present in the KDM5 sub-family [1]. Target engagement and ChIP-seq analysis showed that compound 7 inhibited KDM5B in cells and induced a global increase of the H3K4me3 mark at transcriptional start sites. KDM5B is thus involved in the epigenetic regulatory pathway of immune response and potential targets for antipathogen and anticancer immunotherapy.
