| Popis: | Human histone demethylases are known to play an important role in the development of several tumor types. Consequently, they have emerged as important medical targets for the treatment of human cancer. Herein, structural studies on tetrazolylhydrazide inhibitors as a new scaffold for a certain class of histone demethylases, the JmjC proteins, are reported. A series of compounds are structurally described and their respective binding modes to the KDM4D protein, which serves as a high‐resolution model to represent the KDM4 subfamily in crystallographic studies, are examined. Similar to previously reported inhibitors, the compounds described herein are competitors for the natural KDM4 cofactor, 2‐oxoglutarate. The tetrazolylhydrazide scaffold fills an important gap in KDM4 inhibition and newly described, detailed interactions of inhibitor moieties pave the way to the development of compounds with high target‐binding affinity and increased membrane permeability, at the same time. Bring on the subs! Tetrazolylhydrazide compounds are isosteres of 2‐oxoglutarate, which is the natural cofactor of KDM4 proteins. It is believed that substitution of the carboxylic groups with tetrazole and hydrazide moieties will lead to KDM4 inhibitors with improved physicochemical properties. The binding mode of various such ligands in the active site of KDM4D is elucidated and movements of the interacting amino acid residues upon ligand binding are described. |
