At the Chemical Probes Portal, our mission is to help change the way scientists find and use chemical probes. In addition to providing expert recommendations that guide probe selection and use, we aim to help make it easier for scientists to gain access to the high quality reagents they need to perform robust and reliable experiments. Thus, we are pleased to provide links from our chemical probe pages to the pages of trusted vendors where users can obtain the chemical probes they need.

We are pleased to announce the publication of new chemical probes in the Portal. We have now released validation data for the probes listed below. These probes are still under review by our SAB so it will take a few weeks for ratings and recommendations to emerge. Stay tuned, as we will be releasing more probes as well as inviting new submissions over the coming weeks and months!

We are pleased to announce the publication of chemical probes that target proteins in the PARP family. Today we released validation data for the probes listed below.These probes are still under review by our SAB so it will take a few weeks for ratings and recommendations to emerge. Stay tuned, as we will be releasing more probes as well as inviting new submissions over the coming weeks and months! You can submit your published probe or suggest we add a probe anytime here.

We are currently looking to expand the Portal's database to include inhibitors and chemical probes that target proteins in the Protein methyltransferase (PMT) family. If you have generated and published or published follow-on validation data for chemical probes that are active against PMT proteins please submit your probes to the portal.

For your probe submissions to be considered in our next Batch, please complete the submission by July 18, 2016.

Our new site is now live! Please visit the portal and look around. In addition to the site’s new look, we’ve added new content, including a lot more data about the existing probes, reviewer ratings and their comments. We hope that you will find the site friendly and helpful to use.

Since high-throughput chemical screens have moved into the mainstream of science, medicinal chemists have noted that certain compounds or compound classes repeatedly arise as hits in these assays. Unfortunately, these hits arise repeatedly not because they are versatile and exciting chemical scaffolds but because they are promiscuous entities, which react non-specifically with biomolecules or interfere with assay components rather than directly and specifically affecting the protein target of interest.

By monitoring the interaction between a chemical probe and its protein target in a model system, a researcher gains confidence that the resulting phenotypic changes can be attributed to the probe’s activity against that protein. Assays that allow a researcher to detect and ideally to quantify the protein-chemical probe binding interaction are referred to as target-engagement assays and are considered an essential part of the evidence required to properly validate a probe for use in a biological system.

The Portal will employ an expert peer-review process to vet and rate chemical probes. Key to this process is the Portal’s Scientific Advisory Board (SAB) comprising experts in medicinal chemistry, pharmacology and chemical biology representing a global community and multiple professional environments (e.g., pharma, biotech, clinical centers or academia).
