How to Screen for Transformation Products with SIRIUS

Detecting transformation products is crucial for environmental monitoring, as these byproducts can be more toxic and persistent than their precursor compounds. This tutorial walks you through using SIRIUS for a non-targeted combined precursor and transformation product screening, from generating a transformation product database to analysing LC-HRMS data in SIRIUS and validating results.

Detecting pharmaceuticals and their transformation products with SIRIUS

Pharmaceutical pollution poses risks to ecosystems and human health, yet traditional annotation methods often miss transformation products—drug breakdown compounds that may be even more persistent. We demonstrate how SIRIUS enhances annotation of pharmaceuticals in Luxembourgish rivers, from precursor drug screening to transformation product screening. Our approach for environmental monitoring is relevant not only for pharmaceuticals but also for pesticides and industrial chemicals, whose degradation products may have significant environmental impacts.

Unlocking a Greater Perspective: Mapping the Chemical Space of Biomes Using Sirius

Untargeted mass spectrometry is a powerful tool for analyzing the immense chemical complexity of natural environments. However, interpreting such large datasets remains a significant challenge. To overcome this, researchers have developed an innovative approach using SIRIUS that prioritizes chemical profiling over exhaustive identification. This method allows for more effective comparisons of (micro-)biomes, providing deeper insights into biochemical diversity across different environments.

Screening extractables and leachables with SIRIUS: Plastic-related contaminants in liquor products

In a world where we’re becoming increasingly conscious of what we consume, understanding the potential presence of unexpected extractables and leachables in our food and drinks is paramount. Alcoholic beverages are of particular concern due to their increased affinity and extended storage periods. A non-targeted approach to analysis is essential for uncovering both known and unknown contaminants in our drinks. By analysing fragmentation patterns, SIRIUS predicts chemical structures of unknowns to identify unexpected contaminants and ensure safety of our food.

Long-term storage in biobanks: Identifying unstable metabolites with CSI:FingerID and CANOPUS

Neonatal dried blood spots are not only important for newborn screening but also a powerful source for investigating the potential metabolic etiologies of various diseases using untargeted LC-MS-based metabolomics. So far it is unclear whether the metabolites in those samples remain stable in storage. CSI:FingerID and CANOPUS help to investigate the stability of metabolites and classes of molecules.
