SIRIUS 🤝 BioTransformer: A Dream Team for Unraveling Drug Metabolism

Understanding the metabolic fate of pharmaceutical drugs is a critical component of modern drug discovery and safety testing. Tracking these metabolic changes is notoriously difficult. Identifying the precise structures of drug metabolites within complex mixtures remains a massive analytical bottleneck. To overcome this hurdle, we have integrated BioTransformer in SIRIUS. Researchers have benchmarked this approach using six diverse model drugs and found that it not only bypasses the need for exhaustive manual identification but actively expands our structural coverage of the metabolome.

Decoding the influence of gut microbiota on drug efficacy with SIRIUS

In pharmacology, one of the most significant challenges is the variability in how patients respond to the same drug. While factors like genetics and lifestyle are known to play a role, emerging research points to a hidden player: the human gut microbiota. This vast community of trillions of microbes is an active participant in our health, influencing everything from nutrient absorption to the efficacy of our medications. Using advanced computational tools like SIRIUS to analyze mass spectrometry data, researchers investigated how gut microbiota alter the chemical structure of GPCR drugs.

Ketamine distribution in the brain: understanding drug metabolism with SIRIUS

Ketamine is known for its dual role as an anesthetic and an emerging antidepressant. Despite its long-standing clinical use, the metabolic pathways and pharmacokinetics of ketamine remain poorly understood. A study of ketamine metabolism in the pig brain using SIRIUS provides valuable insights into the distribution of ketamine and its metabolites in different areas of the brain.
