New Deposited Datasets

EUbOPEN Chemogenomic Library (src_id = 55, ChEMBL Document IDs CHEMBL4649982-CHEMBL4649998):
The EUbOPEN consortium is an Innovative Medicines Initiative (IMI) funded project to enable and unlock biology in the open. The aims of the project are to assemble an open access chemogenomic library comprising about 5,000 well annotated compounds covering roughly 1,000 different proteins, to synthesize at least 100 high-quality, open-access chemical probes and to develop infrastructure, technologies and platforms. Screening data generated during this 5 year project will be deposited in ChEMBL. An initial data set of 16 probes/chemogenomic compounds targeting bromodomain proteins has been included in ChEMBL_29.

Donated Chemical Probes - SGC Frankfurt (src_id = 54, ChEMBL Document IDs CHEMBL4630901-CHEMBL4630909):
Data for 9 new chemical probes has been added, along with additional data for some existing probes.

Gates Library compound collection (src_id = 33, ChEMBL Document ID = CHEMBL3988442):
Data for an additional 33 assays screening the Gates Library/GHCDL (68K compounds) has been deposited by the University of Dundee. This includes screening data against a number of pathogenic organisms such as Mycobacterium tuberculosis, Leishmania infantum, Plasmodium falciparum, Schistosoma mansoni and Trypanosoma cruzi

Curated Data Sets

Drug mechanism of action information has been curated for more than 700 additional drugs and clinical candidates in this release.

Updated Data Sources

Scientific Literature
Donated Chemical Probes - SGC Frankfurt
Gates Library compound collection
USP Dictionary of USAN and International Drug Names

Manually Added Drugs
Prodrug active ingredients

Database Changes

Columns Added:
CHEMBL_ID_LOOKUP
Column_name     Data_type     Comment
LAST_ACTIVE     NUMBER(3,0) Indicates the last ChEMBL version where the CHEMBL_ID was active

Web Interface

Drug Warning Browser:
A new Drug Warnings browser has been created (https://www.ebi.ac.uk/chembl/g/#browse/drug_warnings). This allows warning information (black box warnings and drug withdrawals) to be displayed and filtered across all drugs. It can also be accessed from the bubble chart on the home page, or from individual drug pages that have warning information. This browser also incorporates several new features that will be rolled out across other ChEMBL pages in due course, such as improved basic filtering capabilities (allowing text or range filters, depending on filter type) and custom filtering (allowing the user to more easily create sophisticated filters using Elastic search syntax).



Downgraded ChEMBL IDs:
In addition to the changes announced previously (see https://ftp.ebi.ac.uk/pub/databases/chembl/ChEMBLdb/releases/chembl_28/chembl_28_release_notes.txt) regarding resolving of downgraded or deleted ChEMBL entries, an extra field showing the version of ChEMBL in which the entity was last active has now been added. Old versions of ChEMBL can be retrieved from our FTP site, if required.

Downloads

We are no longer be able to provide Oracle 10g/11g/12c dumps. In addition to the usual PostgreSQL/MySQL/SQLite dumps, an Oracle 19c data pump dump is available on request. Please contact us at chembl-help@ebi.ac.uk if you require this.

Funding acknowledgements:

SureChEMBL gets a facelift

By
    Dear SureChEMBL users, Over the past year, we’ve introduced several updates to the SureChEMBL platform, focusing on improving functionality while maintaining a clean and intuitive design. Even small changes can have a big impact on your experience, and our goal remains the same: to provide high-quality patent annotation with a simple, effective way to find the data you need. What’s Changed? After careful consideration, we’ve redesigned the landing page to make your navigation smoother and more intuitive. From top to bottom: - Announcements Section: Stay up to date with the latest news and updates directly from this blog. Never miss any update! - Enhanced Search Bar: The main search bar is still your go-to for text searches, still with three pre-filter radio buttons to quickly narrow your results without hassle. - Improved Query Assistant: Our query assistant has been redesigned and upgraded to help you craft more precise queries. It now includes five operator options: E...

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

By
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

By Eloy
    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...

A python client for accessing ChEMBL web services

By
Motivation The CheMBL Web Services provide simple reliable programmatic access to the data stored in ChEMBL database. RESTful API approaches are quite easy to master in most languages but still require writing a few lines of code. Additionally, it can be a challenging task to write a nontrivial application using REST without any examples. These factors were the motivation for us to write a small client library for accessing web services from Python. Why Python? We choose this language because Python has become extremely popular (and still growing in use) in scientific applications; there are several Open Source chemical toolkits available in this language, and so the wealth of ChEMBL resources and functionality of those toolkits can be easily combined. Moreover, Python is a very web-friendly language and we wanted to show how easy complex resource acquisition can be expressed in Python. Reinventing the wheel? There are already some libraries providing access to ChEM...
