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 - 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…

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.

New SureChEMBL announcement

(Generated with DALL-E 3 ∙ 30 October 2023 at 1:48 pm) We have some very exciting news to report: the new SureChEMBL is now available! Hooray! What is SureChEMBL, you may ask. Good question! In our portfolio of chemical biology services, alongside our established database of bioactivity data for drug-like molecules ChEMBL , our dictionary of annotated small molecule entities ChEBI , and our compound cross-referencing system UniChem , we also deliver a database of annotated patents! Almost 10 years ago , EMBL-EBI acquired the SureChem system of chemically annotated patents and made this freely accessible in the public domain as SureChEMBL. Since then, our team has continued to maintain and deliver SureChEMBL. However, this has become increasingly challenging due to the complexities of the underlying codebase. We were awarded a Wellcome Trust grant in 2021 to completely overhaul SureChEMBL, with a new UI, backend infrastructure, and new f

Accessing SureChEMBL data in bulk

It is the peak of the summer (at least in this hemisphere) and many of our readers/users will be on holiday, perhaps on an island enjoying the sea. Luckily, for the rest of us there is still the 'sea' of SureChEMBL data that awaits to be enjoyed and explored for hidden 'treasures' (let me know if I pushed this analogy too far). See here and  here for a reminder of SureChEMBL is and what it does.  This wealth of (big) data can be accessed via the SureChEMBL interface , where users can submit quite sophisticated and granular queries by combining: i) Lucene fields against full-text and bibliographic metadata and ii) advanced structure query features against the annotated compound corpus. Examples of such queries will be the topic of a future post. Once the search results are back, users can browse through and export the chemistry from the patent(s) of interest. In addition to this functionality, we've been receiving user requests for  local (behind the
