  • Review of literature on protein-reactive natural products.
  • Analysis of natural product mechanisms for enzyme covalent modification.
  • Connecting natural product chemistry to the development of ABPP probes.

Main Results:

  • Natural products provide a rich source of chemical strategies for targeting enzyme active sites.
  • Diverse mechanisms of covalent modification by natural products have been identified.
  • These mechanisms inform the design of novel probes for ABPP.

Conclusions:

  • Inspiration from natural products is crucial for advancing chemical proteomic technologies like ABPP.
  • Understanding natural product-protein interactions aids in developing tools for large-scale functional proteomics.
  • The study underscores the synergistic relationship between natural product chemistry and modern proteomics.
