  Design and synthesis of O-GlcNAcase inhibitors via ‘click chemistry’ and biological evaluations

  摘要：

  Protein O-GlcNAcylation has been shown to play an important role in a number of biological processes, including regulation of the cell cycle, DNA transcription and translation, signal transduction, and protein degradation. O-GlcNAcase (OGA) is responsible for the removal of O-linked beta-N-acetylglucosamine (O-GlcNAc) from serine or threonine residues, and thus plays a key role in O-GlcNAc metabolism. Potent OGA inhibitors are useful tools for studying the cellular processes of O-GlcNAc, and may be developed as drugs for the treatment neurodegenerative diseases. In this study, Cu(I)-catalyzed 'Click' cycloaddition reactions between glycosyl azides and alkynes were exploited to generate inhibitory candidates of OGA. Enzymatic kinetic screening revealed that compound 7 was a potent competitive inhibitor of human O-GlcNAcase (K(i) = 185.6 mu M). Molecular docking simulations of compound 7 into CpOGA (Clostridium perfringens OGA) suggested that strong pi-pi stacking interaction between the compound and W490 considerably contributed to improving the inhibitory activity.
