Area of Science:

  • Biochemistry
  • Immunology
  • Pharmacology

Background:

  • Redox regulation of transcription factors, including activator protein-1 (AP-1) and nuclear factor kappa B (NF-kappaB), plays a significant role in inflammatory diseases.
  • Human thioredoxin (TRX), an oxidoreductase, was initially identified for its role in augmenting interleukin-2 receptor alpha (IL-2R alpha) production in HTLV-1 infected T-cells.

Purpose of the Study:

  • To develop small molecule inhibitors targeting oxidoreductase molecular targets.
  • To validate the therapeutic potential of targeting thioredoxin in a murine asthma model.

Main Methods:

  • Utilized a chemogenomic approach employing an extended strand templated library.
  • Employed solid-phase synthesis for rapid generation of peptide secondary structure mimetics.

    • Successfully developed small molecule inhibitors targeting oxidoreductase activity.
    • Demonstrated the potential of these inhibitors in a relevant disease model.

    Conclusions:

    • The study validates oxidoreductases, specifically thioredoxin, as druggable targets for inflammatory diseases.
    • The developed chemogenomic approach offers a promising strategy for identifying pharmaceutical leads based on protein-peptide interactions.
