In the glycosylphosphatidylinositol (GPI) anchoring pathway, GlcNAc de-N-acetylase is involved in the modification step of the GPI precursor, which is an enzyme involved in the glycosylation modification process. De-N-acetylase catalyzes the removal of the acetyl group in N-acetylglucosamine (GlcNAc) molecules to form N-acetyl glucosamine phosphatidylinositol (GlcNAc-PI), de-N-acetylation is a prerequisite for the mannosylation of GlcN-PI to form the subsequent GPI intermediate. At CD BioGlyco, the development of inhibitors for the biosynthetic process of GlcNAc de-N-acetylase is based on the following contents.
Based on the known structure and reaction mechanism of GlcNAc de-N-acetylase, our research team uses computational chemistry methods to conduct molecular simulations and compound structure design and predict and evaluate the interaction between compounds and enzymes in the computer. In addition, we also use high-throughput screening technology to screen compound libraries on a large scale, which quickly evaluates the inhibitory effect of a large number of compounds on enzyme activity and screens out compounds with potential GlcNAc de-N-acetylase inhibitory activity.
CD BioGlyco uses chemical modification, synthesis method optimization, and other means to optimize the structure of the initially screened GlcNAc de-N-acetylase inhibitor to improve its inhibitory activity and selectivity. At the same time, the subsequent inhibitor synthesis process will be guided through systematic structure-activity relationship research. We synthesize several GlcNH2-PI-based substrate analogs and test them in cells as inhibitors of GlcNAc de-N-acetylase.
CD BioGlyco provides professional GlcNAc de-N-acetylase inhibitor analysis services.

Results: The authors studied the substrate specificity of GlcNAc-PI de-N-acetylase activity in African trypanosomes and human (HeLa) cells. The de-N-acetylase status was indirectly reflected by measuring the release of acetate from GlcNAc-PI and its analogs at different times. The results showed that the HeLa enzyme (Fig B) was pickier than the trypanosome enzyme (Fig A), which didn't act on GlcNAc-PI analogs containing 2-O-octyl-D-inositol, indicating that selective inhibition of trypanosome de-N-acetylase was possible, this enzyme should be considered as a possible therapeutic target.
