March 2025
March 28. A new default result page containing summaries of alerts has been added to SpotRM. This makes it easy to see the scope of a certain alert and then go on to see all the drug examples of it on the classical page.
August 2024
August 1. A new Perspective paper on “Use of Structural Alerts for Reactive Metabolites in the Application SpotRM” was published in Chemical Research in Toxicology by A Claesson. It highlights how well SpotRM signals structural liabilities of the many kinase inhibitors, which are often associated with hepatotoxicity.
August 2022
August 24. A new Perspective paper on “Non-innocuous Consequences of Metabolic Oxidation of Alkyls on Arenes” from Awametox was published in Journal of Medicinal Chemistry by A Claesson and K Parkes. As of 27 August it had been viewed 560 times.
August 16. Great news for all users of Optibrium’s excellent drug design tool StarDrop (see June post below)! You will now be able to access SpotRM for free till year end (use API or the app directly). Just register at SpotRM homepage and mention that you are a StarDrop user and you will automatically be assigned a valid license.
June 2021
SpotRM is now available as plugin to Optibrium’s StarDrop. This plugin is available and usable for free for subscribers to SpotRM. A valid license to use StarDrop is required. Demo versions are available.
January 2021
A presentation “On Safety Aspects of a Methyl Group in Drug Design” is shared by us on SlideShare. There, the problem of a methyl group being metabolically oxidized to a labile/reactive benzylic alcohol is discussed with many examples.
September 2020
A brand new application, SpotRM Web replaces the desktop version SpotRM+.
It features new functionalities regarding batch/multimol searches and has improved regarding structure drawing and text searching. Furthermore:
– The number of drug examples has been increased to 320+.
– The number of monographs has been increased by 14.
– Several smarts have been fine-tuned and the old monographs have been updated.
Also integrated is the possibility of accessing the database via an API!
