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, i

Webinar: using an API to access ChEMBL

  If you use ChEMBL via the interface and are interested in programmatic approaches then join  our  webinar   on November 10th @ 15:30 to find out more ! In this webinar, we'll provide an overview of the ChEMBL and UniChem APIs and work through some common examples. In the meantime, don’t forget that we have further documentation on our  web services  as well as a recent ChEMBL  webinar, a Blog and series of  FAQs .  Questions? Send us a message through the  Helpdesk .

Help us prioritise!

Over the years we've added many new features to ChEMBL and some of these have proved to be particularly valuable to our users. However, our resources are finite, and in order to continue to bring you exciting new improvements, we may sometimes need to re-evalutate features that are not well used and/or costly to maintain. To get the clearest possible view of which of our current data types, formats and access mechanisms are most important to you, we've put together a brief survey. If you're using ChEMBL (whether frequently or not), please help us by completing this - it should only take a couple of minutes! https://www.surveymonkey.co.uk/r/DJ5HPF2 The survey is anonymous and will remain open until 31st October. Thanks in advance for your help.

Pathogen data in ChEMBL

Infectious disease is a leading cause of death globally and bioactivity data against pathogens (fungi, bacteria, viruses, and parasites) is an important category in ChEMBL, especially in light of the ongoing pandemic. In ChEMBL version 29, there are over 2 M bioactivity data points against fungal, bacterial or viral targets (for 460 K compounds) available for pathogen-related research. How can I find pathogen data? On the ChEMBL interface, the organism taxonomy is available as a filter that can be applied to bioactivity data. A sunburst visualisation of the organism taxonomy is also provided as an easy starting point to explore targets according to their taxonomy. In the full database, the organism_classification table holds the underlying data and can be used in bespoke SQL queries. For example, queries may be performed to extract high level pathogen data such as all bioactivity data for small molecules screened against bacterial targets (example below) or more specific subsets focus

New Drug Warnings Browser

As mentioned in the announcement post of  ChEMBL 29 , a new Drug Warnings Browser has been created. This is an updated version of the entity browsers in ChEMBL ( Compounds , Targets , Activities , etc). It contains new features that will be tried out with the Drug Warnings and will be applied to the other entities gradually. The new features of the Drug Warnings Browser are described below. More visible buttons to link to other entities This functionality is already available in the old entity browsers, but the button to use it is not easily recognised. In the new version, the buttons are more visible. By using those buttons, users can see the related activities, compounds, drugs, mechanisms of action and drug indications to the drug warnings selected. The page will take users to the corresponding entity browser with the items related to the ones selected, or to all the items in the dataset if the user didn’t select any. Additionally, the process of creating the join query is no
