SLAS Discovery Kicks Off 2020 with Featured Article, “The National Cancer Institute’s Plated Compound Sets Can Be a Valuable Resource for Academic Researchers”

Oak Brook, IL (USA) — January’s edition of SLAS Discovery features an analysis of two plated sets of synthetic compounds available from the National Cancer Institute (NCI), and the author’s positive and negative results of using this type of collection in his lab’s research.

Adam Zweifach, Ph.D., (The University of Connecticut) points out that NCI’s compound collections are a valuable resource for academic scientists interested in assay development and drug discovery. The benefits, he concludes, are that the compounds provided were at a convenient size to screen manually; available at minimal (if any) cost; their property and activity data is readily available online, and acquiring a re-supply is easy and convenient.

However, he also noted that the collections did have a significant drawback: they can contain a large number of compounds that are pan assay interfering and nonspecific (PAINS), or contain other chemical liabilities revealed by tools like the rapid elimination of swill (REOS) software filters. This means that screening them is likely to generate hits in many assays; this is good, because it allows researchers to validate their assays and post-screening workflows, but also bad because the hits are unlikely to be attractive leads.

To solve this problem, Zweifach suggests that the NCI create a collection of 10,000 carefully selected lead-like compounds pooled into 1000 wells, which may help with the generation of more attractive hits in most assays. He believes that creating this kind of collection would exponentially help advance academic drug discovery efforts and efficiency.

Zweifach  received his doctorate in physiology from Yale University and completed his postdoctoral fellowship at Stanford University. He then established his own lab in the Department of Physiology and Biophysics at the University of Colorado Health Sciences Center before moving to the Department of Molecular and Cell Biology at the University of Connecticut. Here, he became interested in phenotypic screening and has since focused on using high-throughput flow cytometry to discover immunologically active small molecules and on developing ways to use intramolecular FRET sensors based on fluorescent protein pairs for screening.
