Both the Chemical Probes Portal and the Probe Miner resource have been recommended in an excellent new review in Nature Reviews Genetics on the topic of discovering and validating gene dependencies in cancer cells.

To mark its fifteenth anniversary, the latest issue of Nature Chemical Biology (Volume 16 Issue 6, June 2020) has named a selection of papers they describe as their ‘Greatest Hits’ over the last five years.

We feel honoured that one of the selected papers is the Arrowsmith et al Commentary that highlighted the ‘promise and perils of chemical probes’ and announced the launch of the Chemical Probes Portal — described as a ‘a community-driven wiki resource to improve quality and convey current best practice.’

The Portal was founded as an independent organization in February of 2016. Nearly a year and a half later, I offer some reflections on the initiative: I present the rationale for why we insist on data transparency, why we did not adopt strict probe validation criteria, and why I believe the Portal can help improve the quality of the scientific literature even if our experts (Scientific Advisory Board, SAB) never agree on what makes a compound a chemical probe.

Today, an important Perspective was published in Cancer Cell (Choose and use your chemical probe wisely to explore cancer biology). The Perspective highlights both the importance of chemical probes in biomedical research and the unfortunate pollution of scientific literature that occurs when these compounds are misused.

Our crisis in research reproducibility is here to stay, unless we get serious about changing a culture that promotes sloppy research. While much that has been written about the reproducibility crisis emphasizes problems with contaminated cells lines, low quality antibodies and insufficiently powered studies using animal models, any good chemical biologist can identify hundreds if not thousands of studies with small molecules that are also problematic.

Although GPCRs are recognized as the most successful class of druggable targets in the human genome, marketed drugs modulate only about 80 proteins from this very large family. In recognition of their prominence in drug discovery efforts, we have prioritized GPCRs for our next strategic growth phase. We plan to identify chemical probes and best-available compounds for as many of these receptors as we can. We will also highlight commonly used but nonselective compounds (historic compounds) that researchers mistakenly apply as probes to study GPCRs.
