Best expert tool for detecting risks for reactive metabolite formation

Go HERE to explore SpotRM. You will have full access to the system for one day and you can start your evaluation immediately (HELP). Or start by contacting us for a quick demo.

SpotRM collects the world’s most comprehensive knowledge about mechanisms of formation of reactive metabolites in a format that allows quick access to the original literature.  The basis of our selection of structural alerts (SA) was reviewed in Claesson & Minidis, Chem. Res. Toxicol. 2018. The Scope page provides more on this.

SpotRM is available on the Web, via an API, or, upon discussion, the database or parts of for in-house integration. Data are also available via a plug-in for StarDrop from Optibrium. Academics/non-commercial users have free access.


  • Identification of potential hazards in your structure(s) using a carefully designed set of structural alerts.
  • Real drug/compound examples (335+) illustrate the links between SAs and adverse drug effects.
  • Background is explained in concise summaries (Monographs) that are extensively cross-linked.
  • Large selection of links to web-based information, such as literature references, LiverTox db, DailyMed, and more.
  • Several micro-reviews that put most common RM mechanisms into context.
  • Whenever possible, guidance to avoid or replace the particular SA is given.

The most prominent feature of SpotRM is the wealth of information linked to each alert. SpotRM is not a computational tool (no models) but collects the key knowledge for your informed decisions.


  • Drawing a compound in a sketching form.
  • Importing of multi-mol files in SMILES, InChI and SDF formats.
  • Text search on drug names and indications (see HELP).
  • An API for external access to the database enabling integration into your automated workflows.

Below is a brief outline of some basic search and display functionalities of SpotRM.

Analyzing a query STRUCTURE results in highlighting of any SMARTS matches. Example drugs, which contain a particular structural alert, are listed (for meaning of the colour scheme go to Scope). Each listed drug is linked to more information, most often a Monograph that gives condensed information about what is known about reactive metabolite formation associated with the particular drug.
