This study investigated the potential protective effect of extracts from Artemisia absinthium (wormwood) on the stomach. They tested two extracts obtained through hot and room temperature maceration of A. absinthium aerial parts in rats and found that the room temperature extract was more effective. It reduced gastric ulcers and prevented inflammation. The extract seemed to maintain the stomach's protective barrier. Using SIRIUS they putatively identified with a high level of confidence (COSMIC score at least 80%) eight main peaks as tuberonic acid glycoside, rupicolin, 2-hydroxyeupatolide, yangabin, sesartemin, artemetin, isoalantodiene, and dehydroartemorin. These findings support the traditional use of A. absinthium for stomach problems.

Ginger has been used as consumed food spice and folk medicine in daily life for thousands of years in various regions of the world. It is known to exhibit health-promoting effects due to its considerable antioxidation activity. This bioinformatic workflow was developed to generate activity labelled molecular networking (ALMN) to generate antioxidation active molecules profile of Ginger. SIRIUS + CSI:FIngerID was used to conduct high confidence structure annotations of antioxidation active molecules. Consequently, 48 molecules were prioritized as antioxidation active molecules from 11,720 metabolite molecules of Ginger in a systematical way.

Endophytic bacteria are capable of controlling fusarium wilt disease and promoting the growth of tomato plants. Bioactive secondary metabolites produced by the bacteria take part in their biocontrol activity. Sriwati et al explored those metabolites using molecular networks that were annotated through SIRIUS and CSI:FingerID: Clusters were annotated by compound class and many possible structures of secondary metabolites produced by these bacteria were elucidated. Although the active compounds of the bacterial extracts could not be identified, many compounds have the potential to exhibit antibacterial or antifungal activity (containing azole or allylamine subunits).

Researchers are searching for natural antimicrobial agents due to the prevalence of multidrug-resistant pathogens. A rare actinobacteria strain was isolated from Egyptian soil and identified as Amycolatopsis keratiniphila DPA04. Its crude extracts were found to have antimicrobial activity against Gram-positive bacteria. Analysis of the crude extracts using UHPLC-QTOF and SIRIUS + CSI:FingerD led to the identification of 45 metabolites of different chemical classes. ECO-0501 was identified in the cultures with significant antimicrobial activity. Molecular docking studies confirm that it is a promising candidate as MATE (multidrug efflux pump) inhibitor. Natural products from this strain could be useful therapeutic tools for controlling infectious diseases.

This study investigates Phragmites australis, a wetland grass, to understand how metabolites contribute to plant invasion success.They analyzed the plant lipidome and metabolome using SIRIUS and CSI:FingerID to predict molecular structures, which in turn were used to classify compounds using ClassyFire and NPClassifier. Using Random Forests, they identified informative features that distinguished five lineages: European native, North American invasive, North American native, Gulf, and Delta. The study found that each lineage had unique phytochemical fingerprints, with some overlap between North American invasive and native lineages. The results suggest that metabolomic evenness may be a critical trait within plant species.

The use of sunscreen is essential for public health, but the ultraviolet filters in these products can harm marine organisms, including coral. Butyl methoxydibenzoylmethane (BM) is a UV filter that has already been tested for coral inflammation which is not caused by BM. However, coral exposed to BM is subject to a metabolomic shift. Exploring the metabolism of corals exposed to increasing concentrations of BM, SIRIUS+CSI:FingerID identified two carotenoids that are required for the formation of photosynthetic pigment–protein complexes of the thylakoid membrane. The decrease in the relative concentration of these two carotenoids might be indicative of an alteration in the photosynthetic capacity of the coral. We need to evaluate the levels of BM contamination in the reefs and surrounding waters of anthropized areas to assess whether BM could contribute locally to coral bleaching.

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.

Prunus spinosa is a plant with diuretic, laxative, antispasmodic, antimicrobial, anti-inflammatory, and antioxidant properties, recommended for the treatment of various inflammation-related disorders, metabolic diseases, circulatory system disorders, wound healing, and selective growth inhibition of some bacteria strains due to its high content of phenolic acids and flavonoids. Here, an extract from P. spinosa berries was prepared and characterized by identifying compounds commonly known for their biological importance, using SIRIUS+CSI:FingerID and COMSIC. In addition, nanoformulation of the plant extracts in phospholipid vesicles was used to improve extract bioavailability in a potential topical application.

The invasive tree species Miconia calvescens threatens the biodiversity of French Polynesia. This study investigated the impact of M. calvescens on the rhizosphere of six plant species at both the seedling and tree stages. They used metabarcoding and metabolomics to study the diversity of soil organisms and secondary metabolites. Compounds were identified using SIRIUS+CSI:FingerID. The results showed that M. calvescens had a specific association with microeukaryotes of the Cryptomycota family at the tree stage, and this family was positively correlated with the terpenoids found in the soil. The study suggests that these molecules might contribute to the success of M. calvescens as an invasive species.

Alzheimer's disease is a neurodegenerative condition that affects cognitive function and is expected to triple in the US by 2060, with treatment costs projected to rise to over $500 billion annually. Cholinesterase inhibitors can improve cognitive decline by increasing the neurotransmitter acetylcholine, but they also have side effects such as bradycardia, nausea, stomach pain, anorexia, and diarrhea. Endophytic fungi live inside plant tissues without harming their host and produce a variety of bioactive secondary metabolites which are a promising source of novel cholinesterase inhibitor candidates. In this study, metabolites of an Aspergillus niveus ethyl acetate extract were annotated using SIRIUS and CSI:FinegrID. While the isolated compounds displayed only moderate activity against cholinesterases, structurally related metabolites yielded considerable anticholinesterase activities and are promising leads for developing new potent cholinesterase inhibitors.

Liverworts are chemically diverse plants with unique cell organelles responsible for the synthesis and storage of specialized metabolites. Untargeted metabolomics was used to analyze the metabolic stress response of liverworts without isolating individual metabolites. CANOPUS classified the affected compounds and helped to map the biochemical pathways of the unique stress response of liverworts compared to vascular plants.

The strategy of ATP spilling, which involves degrading ATP into ADP to enhance metabolic activity and productivity, has been rarely implemented in Streptomyces species. However, antibiotic production by these microorganisms is known to be triggered in conditions that correlate with low ATP content. Researchers cloned the gene for the DX protein, which dephosphorylates ATP into ADP, and introduced it into Streptomyces albogriseolus/viridodiastaticus. used LC/HRMS2 to analyze the molecules produced by the resulting strain A37 and a control strain A36. Molecular formulas of compounds of interest were predicted with SIRIUS and class annotation was confirmed with CANOPUS. The study demonstrated that DX can be an efficient tool for enhancing specialized metabolic pathways in Streptomyces, potentially leading to the discovery of novel bioactive molecules.
