High-throughput assays for promiscuous inhibitors

Brian Y Feng , Anang Shelat , Thompson N Doman , R Kip Guy & Brian K Shoichet

High-throughput screening (HTS) searches large libraries of chemical compounds for those that can modulate the activity of a particular biological target; it is the dominant technique used in early-stage drug discovery. A key problem in HTS is the prevalence of nonspecific or 'promiscuous' inhibitors.
