Mining Oral Probiotics Based on Their Pathogen Inhibition and Deodorization Roles
Food Bioengineering, EarlyView.A promising oral probiotic strain Streptococcus salivarius MY‐6 stood out from 41 candidate lactic acid bacteria through the high‐throughput strategy based on its inhibitions of the growth and biofilm formation of the main oral pathogens Fusobacterium nucleatum and Porphyromonas gingivalis, as well as its elimination of oral malodor‐associated ...

Investigating the chemistry of pyridinium ylides [PDF]
This thesis describes investigation into catalytic formation of pyridinium ylides from diazo compounds and their subsequent reactivity. In particular, cycloaddition reactions with electrophilic alkenes are performed to generate tetrahydroindolizines that

Spatially Resolved Metabolomics of Optimal Cutting Temperature (OCT) Compound‐Embedded Tumors
International Journal of Cancer, EarlyView.ABSTRACT Mass spectrometry imaging (MSI) is emerging as a powerful tool for uncovering the distribution of metabolites in the tumor microenvironment and studying tumor metabolism in vivo. To date, MSI of biobanked tissues contextualized by patient data has been limited to peptides, proteins, and glycans—with few examples for metabolites.

Pyridinium ylids in synthesis. III. Synthesis of indolizines
, 1967 Treatment of pyridinium, quinolinium, and isoquinolinium ylids with acetylenes yields indolizine derivatives. Pyridinium phenacylid with iodine in dimethylacetamide gives 1,2,3-tribenzoylindolizine.

Ionic liquids: structure–toxicity relationships, predictive toxicology, and sustainable design
Journal of Chemical Technology &Biotechnology, EarlyView.Abstract Ionic liquids (ILs) have often been described as green alternatives to conventional solvents because of their negligible vapor pressure and highly tunable properties. However, low volatility does not necessarily translate into environmental safety, as their biological and ecological effects are strongly influenced by molecular structure.

Journal of Heterocyclic Chemistry, EarlyView.One‐pot gold(I)‐catalysts synthesis was developed in order to prepare N‐alkenyl 2‐pyridonyl azides. This method provides a series of N‐alkenyl 2‐pyridonyl azides in moderate to excellent yields (up to 94%). ABSTRACT A novel strategy, involving the preparation of gold‐catalyzed cyclization salts and the rearrangement of these salts in the presence of ...

Super‐Electron‐Donor Polymers: From Monomer Design to Redox Functionality
Small, EarlyView.2,2'‐Bipyridinylidenes are known for their “super‐electron‐donor” properties and have therefore been used beyond the field of organic synthesis. Their two‐electron redox process at a low potential of 1.8 V vs. Li/Li+ makes them attractive negative p‐type electrode‐active materials.
