It is clear from the analysis of the distribution of approved drug targets that enzymes continue to be a major target class for the pharmaceutical industry. The application of high-throughput screens designed to monitor the activity of these enzyme targets, and the ability of test compounds to modulate this activity, is still the predominant hit finding approach in the industry. The widespread use of enzyme activity-based screens has led to the development of several useful guidelines for the development and validation of robust and reliable assays. Key learnings for the development, validation, and implementation of acoustic mist ionization mass spectrometry for high-throughput enzyme assays are described.
