Area of Science:

  • Biochemistry
  • Enzymology
  • Pharmacology

Background:

  • Proteases are crucial enzymes classified into four mechanistic groups: serine, metallo, aspartic, and cysteine proteases.
  • Dysregulation of protease activity is implicated in numerous human diseases.

Purpose of the Study:

  • To explore the design of targeted protease inhibitors based on mechanistic classification.
  • To highlight the therapeutic potential of specific protease inhibitors in disease treatment.

Main Methods:

  • Classification of novel proteases using general inhibitors.
  • Leveraging mechanistic information from known protease families to design reactive inhibitors.
  • Utilizing transition-state and mechanism-based inhibitors, such as alpha-ketoesters, phosphonates, and heterocyclic isocoumarins for serine proteases.
