canSAR is an integrated database that brings together biological, chemical, pharmacological (and eventually clinical) data. Its goal is to integrate this data and make it accessible to cancer research scientists from multiple disciplines, to aid hypothesis generation and decision making towards identifying causes, biomarkers and therapeutics for cancer.
No. canSAR is freely available to all cancer researchers, both academic and commercial. Please read the Terms of Use.
canSAR is a historical play on words to reflect the fact that it integrates cancer-relevant data with compound Structure-Activity-Relationship (SAR) data. Of course canSAR has grown to be much more than that but the name stuck!
Internet explorer is a non-standards compliant browser. This means that standards laid down by the international community describing various aspects of web protocols are ignored by IE and often cause IE to fail to display the web site. Due to the advanced nature of the web interface provided by canSAR, many of the techniques implemented use technoligies that are not properly supported by IE. We recommend using firefox to benefit from the full functionality of canSAR.
We really appreciate being told about bugs or any other issues you experience while using canSAR. Please email us on cansar@icr.ac.uk.

canSAR data comes from a wide variety of public sources and publications. The ICR internal version of canSAR also includes internally generated experimental data. For latest data sources and statistics, please refer to Data Sources.
We try to have a data and minor functionality update on a monthly basis. However, most of the data in canSAR comes from public sources which have different update cycles. The Data Sources allow you to see the status of each update.
We update 3D structures every week, a couple of days after PDB release new structures in order for us to provide additional annotations and integrate this data with the respective chemical and biological information in canSAR.
No, canSAR searches all alternative names, synonyms, descriptions and keywords.
canSAR target dictionary focusses on human data, although we have a large number of model organism targets. Target key word searches only search human targets . Chemical screening data is from a wide variety of organisms.
Is your target not a human target? Try expanding the search by clicking on "Advanced Search", then choose "All organisms".
If you still cannot find your target (this rarely ever happens), and you can obtain the amino acid sequence of your target from another source, try performing a sequence search. If you still cannot find your target, please let us know by emailing cansar@icr.ac.uk and we will try our best to help.
We annotate compound synonyms in canSAR wherever we can. However, to make sure, please do a chemical structure search. If you think data is missing then please contact us on cansar@icr.ac.uk.
If it is a single target, it is best to view the Target Synopsis and go to the Expression area. There you will find a list of tissues and cell lines with expression levels. See "Target Synopsis" in the Quick Start section for a quick guide on how to do this. If you have multiple targets that you want to know the expression for at once, please use the expression tool (In the tools section)
This information can be obtained from the "Compound Synopsis" Page for a given compound.
At the moment this functionality is not enabled because of the stress it will put on the server, thus possibly hindering other users. We are working to identify the best way to to do this.
We use Symyx Cartridge.
You can do this by viewing the "Target Synopsis" and going to the "Structural ligandability" section.
