Research Interests or Expertise

In the areas of chemical biology and medicinal chemistry, the Lapinsky research group primarily focuses on the rational design and synthesis of clickable covalent compounds. These are valuable compounds that can be used for:

  • Target identification of hit compounds originating from phenotypic screening campaigns
  • Mechanism of action studies, confirmation of target engagement, or selectivity profiling (also known as Affinity-Based Protein Profiling (AfBPP))
  • Characterizing the interactions of small-molecules with drug targets
  • Determining binding sites within target proteins
