The ChEMBL-og

     The Basics of ChEMBL Data Deposition Shortly, we are starting work on ChEMBL 37. Thus, we are running a 1 hour data depositor webinar , for anyone who is planning to deposit data to ChEMBL 37. If you are subscribed to the ChEMBL-depositors mailing list you will have heard about this already. If not, and you have an interest in depositing data to ChEMBL in future, we strongly reccommend you sign up to this  depositor mailing list . This will give you updates on the submission process and deadlines.   Webinar Info We are running on Friday 3 Oct , at 10:00 am , on Zoom . We will post the meeting link to the  ChEMBL-depositors  mailing list the day before.  Learning Objectives of the Webinar This webinar is designed to: Familiarise new depositors with the basic requirements for ChEMBL input data. Re-familiarise former depositors with the deposition process, and explain any new requirements.      A Reminder About ChEMBL 37 deadli...

Breaking news  📢   We are excited to announce our new journal article that presents the comprehensive drug data in ChEMBL. The paper describes the state-of-the-art processes to curate and integrate the high-quality drug and clinical candidate drug data. The drug curation processes have been developed over more than 15 years and this is the first time that they have been published.  https://pubs.acs.org/doi/10.1021/acs.jmedchem.5c00920 Published as a 'Perspectives' article in the Journal of Medicinal Chemistry, the paper educates ChEMBL users, helping them to understand the nature of the drug and clinical candidate data and the rationale that underlies curation decisions. G iven the increasing reliance on high-quality data in computational drug discovery, AI and machine learning, the integrated nature of the drug data within the ChEMBL bioactivity resource is a critical asset. This is a bumper week for drug data in ChEMBL! On Monday, our latest ChEMBL 36 release included ...

Before starting a new drug discovery project, it’s useful to compile existing data on compounds and targets of interest. Open access bioactivity databases such as ChEMBL support these efforts, offering structured and curated data in an easy-to-mine resource. To make the best use of ChEMBL, it’s important to understand the data types, structure and format. With this in mind, the ChEMBL team is providing a free “ Drug Design ” webinar! This webinar provides background on the ChEMBL database alongside worked examples highlighting some common scenarios in drug discovery initiatives. We’ve also included interface demos so that users can follow the examples and build upon these to extract data of interest to their project. We welcome feedback, questions, and suggestions and, as always, you can get in touch with us on our Helpdesk . In addition to this webinar, you can find our other training materials online, such as our deposition guide and introduction to the  API, as well as an FAQ ...

Last year, when I wanted to look at the evolution of ChEMBL over time I found it quite tricky . There were 34 releases at that point, but there was only one database format which was available for all 34 versions - MySQL. But downloading and installing all of these versions was painful as the contents of the .tar.gz are mostly but not exactly consistent, and the appropriate install command has changed a bit over the years. At the same time, since ChEMBL 19 we have provided SQLite versions of ChEMBL. This format is one of the few recommended formats for datasets as specified by the US Library of Congress (alongside JSON, CSV and XML). SQLite is an inherently simpler database format to deal with as it doesn't require the user to setup a server and import the database; rather we provide a .sqlite file which the user can use straightaway after unzipping the .tar.gz. A member of our community, Charles Tapley Hoyt, has gone further and built on this with the ChEMBL Downloader project...

  ChEBI Web Services Retiring on 1st September Over the last few years we’ve been rebuilding ChEBI from the ground up so it’s faster, easier to maintain, and ready for the next decade. If you missed the background story and what’s changed under the hood, our earlier post has the details. https://chembl.blogspot.com/2025/07/redevelopment-of-chebi.html TL;DR The new ChEBI web interface is live at https://www.ebi.ac.uk/chebi/beta/ Old SOAP web services will be retired on 01 September 2025 ; please move to our REST APIs ( https://www.ebi.ac.uk/chebi/backend/api/docs/ ) now. This is the new stable endpoint and will remain so for ChEBI 2.0. Old data product formats are being deprecated end of September 2025 ; new ChEBI 2.0 data products are already available at https://ftp.ebi.ac.uk/pub/databases/chebi-2 (moving to https://ftp.ebi.ac.uk/pub/databases/chebi after switch-over) Final switch-over: by end of September 2025 , the new ChEBI 2.0 interface will replace the current one at https...
