Benzotriazole esters show strong potential for inhibiting the SARS coronavirus main proteinase, a key target for antiviral treatments. These compounds were discovered as intermediates in lopinavir derivative synthesis.

Area of Science:

  • Biochemistry
  • Virology
  • Medicinal Chemistry

Background:

  • The SARS coronavirus main proteinase (CoV main proteinase) is a critical enzyme for viral replication.
  • Targeting the CoV main proteinase is a key strategy for developing antiviral therapies against SARS coronavirus.
  • Existing antiviral drug development includes exploring novel chemical scaffolds.

Purpose of the Study:

  • To investigate the inhibitory potential of benzotriazole esters against the SARS coronavirus main proteinase.
  • To identify new therapeutic agents for SARS coronavirus infection.

Main Methods:

  • Synthesis of benzotriazole esters as potential enzyme inhibitors.
  • Enzyme inhibition assays to evaluate the efficacy of synthesized compounds.
  • Analysis of structure-activity relationships for benzotriazole ester derivatives.
