ChEMBL_16 Released

We are pleased to announce the release of ChEMBL_16. This version of the database was prepared on 7th May 2013 and contains:

1,481,473 compound records
1,295,510 compounds (of which 1,292,344 have mol files)
11,420,351 activities
712,836 assays
9,844 targets
50,095 documents
19 activity data sources

You can download the data from the ChEMBL ftpsite and do not forget to read the ChEMBL_16 Release Notes

Data changes since the last release
ChEMBL_16 includes the Millipore Kinase Screening publication (CHEMBL2218924), which is kinase screening panel data set focused on 158 known kinase inhibitors and the OSDD Malaria Screening dataset (CHEMBL2113921), which is a set of anti-malarial compounds and bioactivity data provided by the OSDD Malaria consortium
In addition to the our regular publication and dataset updates we are now also loading supplementary bioactivity datasets. In this example the original paper from GSK was published in 2010 (CHEMBL1157114) and with the release of ChEMBL_16 we now provide 2 supplementary datasets (CHEMBL2218064 and CHEMBL2094195). You can see the original paper an supplemenatry datasets in screenshot below (this also demonstrates the new document search functionality we have added to the interface):

We are would like grow our supplementary bioactivity datasets, so please get in touch if you have any similar data you would like to deposit in the ChEMBL database. Stefan Senger from GSK, has put together the following slides, which provide more details on the pros and pros of depositing  supplementary bioactivity data. (Also thanks Derek Lowe over at In The Pipeline for the following blog post).

Interface changes since the last release:
We have made a number changes to the interface which are listed below:
  • Document Search - Submit a keyword search against journal articles and datasets loaded into the database
  • Browse Targets - We have improved the tree browser on protein classification and organism browser targets page 
  • Browse Drugs - Now allows searching on USAN stem and ATC code definitions
  • Updated FAQ pages - see here
  • Target Report Card - Now contains a target relation section, providing links between targets sharing protein components. The target report card also includes links to CREDO and TIMBAL databases
  • Compound Report Card - Includes a link to NCI Resolver service, to retrieve additional synonyms for a compound
In addition to our regular set of downloads (Oracle, MySQL, PostgreSQL) you will also find RDF version on the ChEMBL database. The current version is 16.0 and the files are available to download here. You can expect some minor changes in the RDF between now and the ChEMBL_17 release and these will be represented by increments in the minor version number

UniChem 2.0

UniChem new beta interface and web services We are excited to announce that our UniChem beta site will become the default one on the 11th of May. The new system will allow us to better maintain UniChem and to bring new functionality in a more sustainable way. The current interface and web services will still be reachable for a period of time at . In addition to it, the most popular legacy REST endpoints will also remain implemented in the new web services: Some downtime is expected during the swap.  What's new? UniChem’s current API and web application is implemented with a framework version that’s not maintained and the cost of updating it surpasses the cost of rebuilding it. In order to improve stability, security, and support the implementation and fast delivery of new features, we have decided to revamp our user-facing systems using the latest version of widely used and maintained frameworks, i

A python client for accessing ChEMBL web services

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 ChEMBL d

LSH-based similarity search in MongoDB is faster than postgres cartridge.

TL;DR: In his excellent blog post , Matt Swain described the implementation of compound similarity searches in MongoDB . Unfortunately, Matt's approach had suboptimal ( polynomial ) time complexity with respect to decreasing similarity thresholds, which renders unsuitable for production environments. In this article, we improve on the method by enhancing it with Locality Sensitive Hashing algorithm, which significantly reduces query time and outperforms RDKit PostgreSQL cartridge . myChEMBL 21 - NoSQL edition    Given that NoSQL technologies applied to computational chemistry and cheminformatics are gaining traction and popularity, we decided to include a taster in future myChEMBL releases. Two especially appealing technologies are Neo4j and MongoDB . The former is a graph database and the latter is a BSON document storage. We would like to provide IPython notebook -based tutorials explaining how to use this software to deal with common cheminformatics p

ChEMBL 30 released

  We are pleased to announce the release of ChEMBL 30. This version of the database, prepared on 22/02/2022 contains: 2,786,911 compound records 2,157,379 compounds (of which 2,136,187 have mol files) 19,286,751 activities 1,458,215 assays 14,855 targets 84,092 documents Data can be downloaded from the ChEMBL FTP site: Please see ChEMBL_30 release notes for full details of all changes in this release: New Deposited Datasets EUbOPEN Chemogenomic Library (src_id = 55, ChEMBL Document ID CHEMBL4689842):   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

Multi-task neural network on ChEMBL with PyTorch 1.0 and RDKit

  Update: KNIME protocol with the model available thanks to Greg Landrum. Update: New code to train the model and ONNX exported trained models available in github . The use and application of multi-task neural networks is growing rapidly in cheminformatics and drug discovery. Examples can be found in the following publications: - Deep Learning as an Opportunity in VirtualScreening - Massively Multitask Networks for Drug Discovery - Beyond the hype: deep neural networks outperform established methods using a ChEMBL bioactivity benchmark set But what is a multi-task neural network? In short, it's a kind of neural network architecture that can optimise multiple classification/regression problems at the same time while taking advantage of their shared description. This blogpost gives a great overview of their architecture. All networks in references above implement the hard parameter sharing approach. So, having a set of activities relating targets and molecules we can tra
