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 https://www.ebi.ac.uk/unichem/legacy.
In addition to it, the most popular legacy REST endpoints will also remain implemented in the new web services: https://www.ebi.ac.uk/unichem/api/docs#/Legacy
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, infrastructure, and the best practices in our software engineering processes.

We have separated the API (backend) to the Web Application systems, which contributes to the system’s overall availability and stability, as well as facilitating features delivery. Both built using popular programming languages and frameworks.

Modern API

Our web services are now implementing current REST standards such as JSON payloads for the request and response, allowing a more intuitive experience for the users. The way the services are called and its response has been simplified but retaining the same functionality.

To improve usability we provide a live and interactive documentation where users can explore the functionalities by reading and directly trying them.

In-depth documentation and information can be found here.

Modern Web Interface

Built using the latest version of a very popular frontend framework and widely used libraries which allow us to provide enhanced user experience and a more pleasant user interface, while at the same time providing better accessibility features.

Get more information about the exciting new and upcoming features, as well as how to use it here.

Compound sources and connectivity searches

Searches for a specific compound can be done using the traditional InChI, InChI Key, or its ID on an specific source database, additional to that users can now search by drawing their molecule on the sketcher

Drawing a compound to search using the Sketcher

As part of the web services simplification we changed the way the endpoint is used, by moving the information requested to a JSON payload.

Here is an example of how it works on the current version:

And this is an example for the same search on the new UniChEM:

Backwards compatibility

We have identified which endpoints are used the most and have re implemented them in order to offer backwards compatibility and ease the transition between the current and new system.

We do encourage users to switch to the new endpoints as they are implemented using the latest standards and best practices.

SureChEMBL Available Now

Followers of the ChEMBL group's activities and this blog will be aware of our involvement in the migration of the previously commercially available SureChem chemistry patent system, to a new, free-for-all system, known as SureChEMBL. Today we are very pleased to announce that the migration process is complete and the SureChEMBL website is now online. SureChEMBL provides the research community with the ability to search the patent literature using Lucene-based keyword queries and, much more importantly, chemistry-based queries. If you are not familiar with SureChEMBL, we recommend you review the content of these earlier blogposts here and here . SureChEMBL is a live system, which is continuously extracting chemical entities from the patent literature. The time it takes for a new chemical in the patent literature to become searchable in the SureChEMBL system is 1-2 days (WO patents can sometimes take a bit longer due to an additional reprocessing step). At time of writi

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

ChEMBL & SureChEMBL anniversary symposium

In 2024 we celebrate the 15th anniversary of the first public release of the ChEMBL database as well as the 10th anniversary of SureChEMBL. To recognise this important landmark we are organising a two-day symposium to celebrate the work achieved by ChEMBL and SureChEMBL, and look forward to its future. Save the date for the ChEMBL 15 Year Symposium October 1-2, 2024 Day one will consist of four workshops, a basic ChEMBL drug design workshop; an advanced ChEMBL workshop (EUbOPEN community workshop); a ChEMBL data deposition workshop; and a SureChEMBL workshop. Day two will consist of a series of talks from invited speakers, a few poster flash talks, a local nature walk, as well as celebratory cake. During the breaks, the poster session will be a great opportunity to catch up with other users and collaborators of the ChEMBL resources and chat to colleagues, co-workers and others to find out more about how the database is being used. Lunch and refreshments will be pro

ChEMBL 34 is out!

We are delighted to announce the release of ChEMBL 34, which includes a full update to drug and clinical candidate drug data. This version of the database, prepared on 28/03/2024 contains: 2,431,025 compounds (of which 2,409,270 have mol files) 3,106,257 compound records (non-unique compounds) 20,772,701 activities 1,644,390 assays 15,598 targets 89,892 documents Data can be downloaded from the ChEMBL FTP site: https://ftp.ebi.ac.uk/pub/databases/chembl/ChEMBLdb/releases/chembl_34/ Please see ChEMBL_34 release notes for full details of all changes in this release: https://ftp.ebi.ac.uk/pub/databases/chembl/ChEMBLdb/releases/chembl_34/chembl_34_release_notes.txt New Data Sources European Medicines Agency (src_id = 66): European Medicines Agency's data correspond to EMA drugs prior to 20 January 2023 (excluding vaccines). 71 out of the 882 newly added EMA drugs are only authorised by EMA, rather than from other regulatory bodies e.g.

RDKit, C++ and Jupyter Notebook

Fancy playing with RDKit C++ API without needing to set up a C++ project and compile it? But wait... isn't C++ a compiled programming language? How this can be even possible? Thanks to Cling (CERN's C++ interpreter) and xeus-cling jupyter kernel is possible to use C++ as an intepreted language inside a jupyter notebook! We prepared a simple notebook showing few examples of RDKit functionalities and a docker image in case you want to run it. With the single requirement of docker being installed in your computer you'll be able to easily run the examples following the three steps below: docker pull eloyfelix/rdkit_jupyter_cling docker run -d -p 9999:9999 eloyfelix/rdkit_jupyter_cling open http://localhost:9999/notebooks/rdkit_cling.ipynb in a browser
