Here at ChEMBL, we are often contacted by users who are interested in purchasing some of the compounds that we store in our databases. However, our compounds are curated directly from the literature and we do not have access to physical samples. To enable our users to find supplier information for the compounds, we have now added direct links from ChEMBL to ChemSpider. ChemSpider is a resource containing millions of chemical structures, with associated property information. This property information also includes supplier information, where available. You can connect to ChemSpider via our Compound Report Card, under "Database Links" and by clicking on the Standard InchiKey hyperlink you will be taken directly to the same compound in ChemSpider. You can also connect directly to ChEMBLdb via ChemSpider using the hyperlink found under their "Biological Data" tab.
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
