Open Data for Neglected Tropical Disease Discovery, and Release of ChEMBL-04

It was clearly a slow news day in Swindon that day; but, in a way, wouldn't it be nice to live a place where this was big news. I for one, am glad the tortoise is OK (google with the headline and you'll get the full, detailed story).

Anyway, there are some significant publications in Nature this week on HTS screening and follow-up for Malaria screens (the papers are free content at the moment - Gamo et al, and Guiguemde et al. There are also some press releases for these papers and the public data release. We won't repeat the content of these formal things, but here provide some informal commentary...

The magic data pixies here at EMBL-EBI have been working hard and we have loaded all the data into the latest release of our SAR database - ChEMBL04. The data is now live in the web interface, and the ftp download of the whole database will be in the near future (we are still optimising our production processes, so sorry that the data is available in the front-end before the download files are fully ready and tested - but we took the view that people would probably not want us to hold back access where possible. However, the gap between loading into the front-end schema and the packaged export release will shorten.

We have also put together a 'microsite' called ChEMBL-NTD (NTD stands for Neglected Tropical Disease) accessible at http://www.ebi.ac.uk/chemblntd - this showcases and provides easy download of raw data from ChEMBL for this strategically important set of diseases, and also allows the addition of extra functionality for visualisation that isn't available in the ChEMBL front end. We have some exciting plans for community annotation of these data-sets, and more on this later. At the moment, there are download links, in a variety of common formats, for the GSK, St. Judes, and Novartis. Unfortunately we only had time to build some interactive query tools for the ChEMBL plasmodium and GSK datasets; but rest assured, were putting together some tools for cross datasets analysis and querying (given the scientific limits of analysis of large sets of single point screening data).


As you will probably guess, there are more data-sets in the pipeline for release, and we would be delighted if others with similar datasets would be interested in publicly archiving them here at the EMBL-EBI. As always, all the EMBL-EBI data is freely accessible, redistributable, etc>.

If you have any feedback on data formats, the interface, etc please let us know.

Chembl04 contains 680,293 compound records, 565,243 distinct compounds, and 2,705,136 assay data points.

Finally, a heartfelt thanks to many people who have helped us put this together, championed the release of data from their organisations, and acted as the social glue that is so important in getting these sort of things actually done. As the youth the world over now say - respect to Rick Keenan, Jose Garcia-Bustos, Frederic Bost, Pascal Fantauzzi, Richard Glynne, Thierry Diagana, Anang Shelat and Kip Guy!

Can anyone tell me how to get these compounds and where i can get the available vendor list
jpo said…
Hi,

Some of the compounds are available commercially - it is pretty simple to do a search against ZINC to get a good starting point for sourcing the compounds. Let us know if you'd like us to look at this for you.

You could also try contacting either St. Judes, Novartis, or GSK (as appropriate and using the contact details in the papers) to get some samples. But they may not have sufficient sample left, and also I know have been inundated with request following the publications.

Here's a nice Christmas gift - ChEMBL 35 is out!

Use your well-deserved Christmas holidays to spend time with your loved ones and explore the new release of ChEMBL 35!            This fresh release comes with a wealth of new data sets and some new data sources as well. Examples include a total of 14 datasets deposited by by the ASAP ( AI-driven Structure-enabled Antiviral Platform) project, a new NTD data se t by Aberystwyth University on anti-schistosome activity, nine new chemical probe data sets, and seven new data sets for the Chemogenomic library of the EUbOPEN project. We also inlcuded a few new fields that do impr ove the provenance and FAIRness of the data we host in ChEMBL:  1) A CONTACT field has been added to the DOCs table which should contain a contact profile of someone willing to be contacted about details of the dataset (ideally an ORCID ID; up to 3 contacts can be provided). 2) In an effort to provide more detailed information about the source of a deposited dat...

Improvements in SureChEMBL's chemistry search and adoption of RDKit

    Dear SureChEMBL users, If you frequently rely on our "chemistry search" feature, today brings great news! We’ve recently implemented a major update that makes your search experience faster than ever. What's New? Last week, we upgraded our structure search engine by aligning it with the core code base used in ChEMBL . This update allows SureChEMBL to leverage our FPSim2 Python package , returning results in approximately one second. The similarity search relies on 256-bit RDKit -calculated ECFP4 fingerprints, and a single instance requires approximately 1 GB of RAM to run. SureChEMBL’s FPSim2 file is not currently available for download, but we are considering generating it periodicaly and have created it once for you to try in Google Colab ! For substructure searches, we now also use an RDKit -based solution via SubstructLibrary , which returns results several times faster than our previous implementation. Additionally, structure search results are now sorted by...

Improved querying for SureChEMBL

    Dear SureChEMBL users, Earlier this year we ran a survey to identify what you, the users, would like to see next in SureChEMBL. Thank you for offering your feedback! This gave us the opportunity to have some interesting discussions both internally and externally. While we can't publicly reveal precisely our plans for the coming months (everything will be delivered at the right time), we can at least say that improving the compound structure extraction quality is a priority. Unfortunately, the change won't happen overnight as reprocessing 167 millions patents takes a while. However, the good news is that the new generation of optical chemical structure recognition shows good performance, even for patent images! We hope we can share our results with you soon. So in the meantime, what are we doing? You may have noticed a few changes on the SureChEMBL main page. No more "Beta" flag since we consider the system to be stable enough (it does not mean that you will never ...

ChEMBL brings drug bioactivity data to the Protein Data Bank in Europe

In the quest to develop new drugs, understanding the 3D structure of molecules is crucial. Resources like the Protein Data Bank in Europe (PDBe) and the Cambridge Structural Database (CSD) provide these 3D blueprints for many biological molecules. However, researchers also need to know how these molecules interact with their biological target – their bioactivity. ChEMBL is a treasure trove of bioactivity data for countless drug-like molecules. It tells us how strongly a molecule binds to a target, how it affects a biological process, and even how it might be metabolized. But here's the catch: while ChEMBL provides extensive information on a molecule's activity and cross references to other data sources, it doesn't always tell us if a 3D structure is available for a specific drug-target complex. This can be a roadblock for researchers who need that structural information to design effective drugs. Therefore, connecting ChEMBL data with resources like PDBe and CSD is essen...
