Accelerating CNS Positron Emission Tomography (PET) Ligand Discovery

ACS Webinars

PET ligands play important roles in drug discovery relating to the central nervous system. However, the discovery efforts of PET ligands have suffered from high attrition rates due to a demanding list of required attributes and a lack of guiding principles in ligand design and prioritization. Join Lei Zhang as he lays out a set of preferred parameters for CNS PET ligand design which has been derived from a systematic analysis of a PET ligand database. These preferred parameters have been applied prospectively applied to a number of programs within Pfizer, yielding successful PET ligands with reduced resources and timelines.

What You Will Learn

  • What makes good PET ligands and what values do they bring to drug discovery
  • What is the desired property space for PET ligands
  • How to prospectively use the defined design parameters to accelerate PET ligand discovery
