GPI-phosphoethanolamine Transferase Inhibitor Development Service

GPI-phosphoethanolamine Transferase Inhibitor Development Service

GPI-phosphoethanolamine Transferase (GPI-PET) Inhibitor Development Service at CD BioGlyco

GPI-PET is an enzyme involved in the modification of GPI-anchored proteins by phosphoethanolamine. During the synthesis of mammalian GPI anchors, three different GPI-PETs add phosphoethanolamine (P-EthN) groups to each of the three Man residues in the GPI glycan core. This step is critical for GPI anchoring because the P-EthN group provides the link between the glycolipid and the protein. CD BioGlyco has one-stop Glycosylation Inhibitor Development solutions, and we provide you with an efficient and flexible GPI-PET inhibitor development service.

  • Flexible inhibitor screening service

CD BioGlyco provides high-quality GPI-PET inhibitor development services in multiple pathways.

    • We use methods such as high-throughput screening (HTS) to screen compound libraries to find potential GPI-PET inhibitors. The screened inhibitors are chemically modified and structurally optimized to improve their inhibitory activity and physical and chemical properties.
    • We design and develop specific antibodies or protein inhibitors that interfere with the functions of GPI-PET.
    • We use RNA interference technology to interfere with the expression of the GPI-PET gene, thereby inhibiting its functions.
    • In addition, we also use clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9 (CRISPR/Cas9) gene editing technology to perform targeted editing or silencing of the GPI-PET gene to achieve GPI-PET inhibition.
  • Activity assessment service

CD BioGlyco provides efficient GPI-PET inhibitor evaluation services to verify their inhibitory efficacy and selectivity.

    • Inhibitor preparation: We prepare and purify the GPI-PET inhibitors to be evaluated through chemical synthesis, isolation, and purification.
    • Enzyme activity assay: We use appropriate enzyme activity assay methods, such as fluorescent enzyme activity assays, radioactive assays, etc., to evaluate the activity of GPI-PET enzymes.
    • Concentration-dependent study: We provide study services on the effect of inhibitors on GPI-PET activity at different concentrations. By drawing the inhibitory activity curve and calculating the half-maximal inhibitory concentration (IC50), we determine the potential inhibitory ability of the inhibitor on GPI-PET.
    • Cell-level evaluation: At the same time, we provide an assessment of the biosynthesis of GPI-anchored proteins by inhibitors, such as detecting the expression, secretion, or cellular localization of GPI-anchored proteins.
  • Inhibitor production service

In addition, CD BioGlyco provides mature GPI-PET inhibitor production service. We select appropriate synthesis routes, reaction conditions, catalysts, solvents, and other process conditions to optimize the production process of GPI-PMT inhibitors, thereby ensuring that the production process is efficient, repeatable, and has good product yields.

Results: The authors studied the mechanism of action of 1,10-phenanthroline (PNT) on GPI anchor synthesis. PNT was added to HeLa cells. As its concentration increased, the level of H6 reached a maximum at 100 μM PNT, while H2 detected that higher PNT concentrations resulted in greater H2 accumulation and a parallel decrease in H6. Studies showed that PNT was a novel inhibitor of GPI-anchored synthesis that caused the accumulation of GPI-anchored intermediates that were substrates for GPI-PET, suggesting that these enzymes were targets of PNT.

Applications

  • Disease research: GPI-anchored proteins are related to a variety of diseases, such as congenital diseases and neurological diseases. The development of GPI-PET inhibitors helps further understand the mechanism of GPI modification in these diseases and may provide new potential targets for the research of related diseases.
  • Drug screening and development: Developing inhibitors against GPI-PET are used for drug screening and development. Potential drug candidates are discovered by screening a library of compounds with GPI-PET inhibitory activity.
  • Bioengineering and production: GPI-anchored proteins have important applications in bioengineering and production. The development of GPI-PET inhibitors provides a means to control GPI modifications in industrial production and regulate product expression, purification, and functions.

Advantages

  • Advanced experimental facilities: CD BioGlyco is equipped with advanced laboratory facilities and instruments to support efficient GPI-PET inhibitor screening, optimization, and evaluation.
  • Diverse screening means: We have diverse screening means, including cell lines, enzyme reactions, or in vivo models, to quickly evaluate the activity and selectivity of candidate GPI-PET inhibitors.
  • Custom services: We provide custom GPI-PET inhibitor development services efficiently and flexibly, and we will provide the best solutions for different stages of inhibitor development.
