How SIRIUS Mapped the Chemical Shield Against “Superbugs” in the Infant Gut

Antimicrobial resistance in early life represents a critical global health challenge, particularly in low- and middle-income countries. Researchers investigated whether early-life oral probiotic supplementation can metabolically reprogram the infant gut microbiome to exclude antibiotic-resistant superbugs. Using SIRIUS-powered untargeted metabolomics, the team elucidated the resulting metabolic reprogramming. They found that high levels of beneficial Bifidobacterium drives a protective environment flooding the gut with organic acids and creating a protective chemical shield against drug-resistant Enterobacterales.

SIRIUS-ly Toxic: Mapping Unknown Urinary Biomarkers Derived from Deep-Fried Foods

Every day, our bodies encounter millions of foreign chemical compounds. Among the most dangerous are reactive electrophilic species—unstable molecules that can bind to DNA and proteins, potentially leading to chronic diseases. Fortunately, our bodies fight back using glutathione conjugation, excreting these toxins as urinary mercapturic acid conjugates (MACs). But until now, checking urine to see exactly what toxins we’ve been exposed to was incredibly difficult because standard tracking methods miss highly unstable chemical structures. Researchers developed an analytical strategy that dramatically expands our ability to profile the urinary “adductome”. By pairing high-resolution mass spectrometry with customized database construction and automated computational annotation using SIRIUS, this workflow uncovers hundreds of previously untraceable biomarkers.

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.

Solving the Wolf’s Bane Puzzle: Breaking the Synthesis Bottleneck for Diterpenoid Alkaloid Therapeutics

Diterpenoid alkaloids represent an exceptionally complex class of plant metabolites, highly valued for their therapeutic properties. But their extreme structural complexity makes chemical synthesis practically unfeasible, while their trace abundance in wild plants creates a massive bottleneck for pharmaceutical scale-up. Bio-manufacturing in heterologous hosts offers a viable alternative. But how do these plants assemble the highly complex, medicinal alkaloids and what is the exact origin of their nitrogen building blocks?

Environmental and Maternal Drivers of the Infant Gut Metabolome Revealed Using SIRIUS

The maturation of the gut microbiome during the first six months of life is a foundational process, playing a key role in metabolic programming and training of the immune system, but these patterns remain critically underexplored in populations from low- and middle-income countries. To address this gap, an observational, longitudinal study profiled the developing gut microbiome and metabolome in Bangladesh using a multi-omics approach. Systematic classification and metabolite annotation was achieved using SIRIUS. The overall aim was to understand how maternal and environmental factors—specifically delivery mode, maternal milk composition, and household water treatment—shape this foundational postnatal development.

Reducing PFAS Emissions: Efficacy of Abatement Systems at Fluoropolymer Plants Investigated Using SIRIUS

Fluoropolymer production plants are an obvious source for PFAS emission into our environment. They have invested in abatement systems to curtail the emission of PFAS but their efficacy has not been reported in peer-reviewed literature. A recent study investigates their efficacy and reveals a more complex emission profile than previously understood. In a suspect screening approach using SIRIUS, they detected a homologous series of previously overlooked polymerization byproducts.

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.

SIRIUS in Space: The ISS metabolome

As we prepare for longer human missions beyond Earth, understanding the invisible ecosystems of space habitats has become critical for astronaut health. The International Space Station (ISS) is not just a home and laboratory—it is also a closed microbial and chemical environment unlike anything on Earth. This study mapped the ISS microbiome and metabolome in unprecedented detail, uncovering its vast chemical “dark matter” using SIRIUS.

Going Barcode-Free: Screening Massive Small Molecule Libraries for Early Drug Discovery

Our recent study co-authored by researchers at Bright Giant, FSU Jena, Leiden University and Oncode Institute introduces a major leap forward in affinity selection screening for early drug discovery: Self-Encoded Libraries. Our approach uses advanced mass spectrometry to screen hundreds of thousands of small molecules in a single experiment, bypassing the significant limitations of traditional high-throughput screening as well as affinity selection with barcoded libraries. It allows drug discovery teams to identify high-affinity drug candidates faster, more affordably, and against targets previously inaccessible to common screening methods.
