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 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.

Donated Chemical Probes - SGC Frankfurt (src_id = 54, ChEMBL Document IDs CHEMBL4800721-CHEMBL4800732):
Data for new chemical probes has been added.

New Data Sources

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 wishes you a Merry Christmas: A look back and a glimpse into 2023!

 The ChEMBL Team heads off soon on their Christmas holidays! Before we leave, we would like to remember  some highlights of 2022 and share some outlook for the next year! 2022 was an extraordinary year for the UK and also for the ChEMBL Team! It was a year of celebrations, farewells, and new beginnings....   The ChEMBL team underwent major personnel changes in 2022 , with Anna and Patricia leaving the team, and Barbara, Eloy and Fiona taking on new roles within the ChEMBL leadership team. 2022 was a year of extremes as well. The UK recorded >40C in July and -6C in the past few days in December.  During the hot summer months the ChEMBL Team went on a punting excursion on the River Cam. In 2022, the ChEMBL Team delivered lots of training and outreach activities including a "Wetland Nature Trail" on Campus organised by Emma and James. We also participated in the "School of Chemoinformatics in Latin America", where the ChEMBL web-interface and API were explained

This Python InChI Key resolver will blow your mind

This scientific clickbait title introduces our promised blog post about the integration of UniChem into our ChEMBL python client. UniChem is a very important resource, as it contains information about 134 million (and counting) unique compound structures and cross references between various chemistry resources. Since UniChem is developed in-house and provides its own web services , we thought it would make sense to integrate it with our python client library . Before we present a systematic translation between raw HTTP calls described in the UniChem API documentation and client calls, let us provide some preliminary information: In order to install the client, you should use pip : pip install -U chembl_webresource_client Once you have it installed, you can import the unichem module: from chembl_webresource_client.unichem import unichem_client as unichem OK, so how to resolve an InChI Key to InChI string? It's very simple: Of course in order to reso
