Lactone Enolates of Isochroman-3-ones and 2‑Coumaranones: Quantification of Their Nucleophilicity in DMSO and Conjugate Additions to Chalcones [PDF]

Owing to stereoelectronic effects, lactones often deviate in reactivity from their open-chain ester analogues as demonstrated by the CH acidity (in DMSO) of 3-isochromanone (pKa = 18.8) and 2-coumaranone (pKa = 13.5), which is higher than that of ethyl ...

Distinctive metabolic disturbances associated with redox homeostasis, nervous and hormonal functions during gut microbial enrichment upon polystyrene microplastic exposure

iMetaOmics, Volume 2, Issue 4, December 2025.
Microplastic‐induced gut microbial enrichment was dominated by bacteria within Eubacteriales, correlated with the virome, and accompanied by colitis. The polyamine synthetic pathway was activated to maintain glutathionylspermidine homeostasis, concurrent with decreases in pathways involved in the production of energy and reactive oxygen species under ...

Multi‐Omics Signatures of Periodontitis and Periodontal Therapy on the Oral and Gut Microbiome

Journal of Periodontal Research, Volume 60, Issue 12, Page 1237-1253, December 2025.
This multi‐omics study integrates shotgun metagenomics and NMR metabolomics to reveal coordinated microbial and metabolic signatures of periodontitis across the oral–gut axis. Non‐surgical periodontal therapy partially restored ecological and functional balance, supporting oral health as a modifiable driver of systemic microbial homeostasis.

Some Pyrolitic Reactions of Salts of Organic Acids [PDF]

, 1955
As a result of a number of isotopic and non-isotopic pyrolyses of salts of carboxylic acids, a new theory for the mechanism of these thermal decompositions has been proposed.

Phenylacetate Hydroxylase SsPhacA Modulates p‐Coumaric Acid Accumulation to Regulate the Mating/Filamentation of Sporisorium scitamineum

Molecular Plant Pathology, Volume 26, Issue 12, December 2025.
SsPhacA regulates the phenylalanine metabolic pathway to modulate p‐coumaric acid accumulation, which increases the transcriptional level of SsPRF1, thereby regulating sexual reproduction in S. scitamineum. ABSTRACT Sugarcane smut, caused by Sporisorium scitamineum, is one of the most severe sugarcane diseases.

A formal method for the de-N,N-dialkylation of Sommelet-Hauser rearrangement products [PDF]

, 2012
Selective amine de-alkylation enables the conversion of Sommelet–Hauser rearrangement products into 2-aryl-2-bromoacetic acid derivatives. These compounds are valuable synthetic intermediates in the synthesis of α-aryl-α-amino or α-aryl-β-amino acid ...

Bacterial fitness for plant colonization is influenced by plant growth substrate

New Phytologist, Volume 248, Issue 6, Page 3168-3190, December 2025.
Summary Despite advances in our understanding of bacterial plant colonization, the extent to which growth substrate influences the molecular mechanisms enabling bacteria to efficiently colonize plants remains poorly understood. To address this, we used randomly barcoded transposon mutagenesis sequencing (RB‐TnSeq) in Paraburkholderia graminis OAS925 ...

Sequential Ester Homologation–Nucleophile‐Guided Functionalization: A Chemoselective Access to Thioesters, Amides, and Acids

Chemistry–Methods, Volume 5, Issue 11, November 2025.
The homologation of esters—in the presence of a lithium carbenoid—to thioesters, amides, and carboxylic acid is reported. By controlling the tetrahedral intermediate collapsing and promoting a series of rearrangements ultimately leading to a high electrophilic ketene, the subsequent incorporation of S‐, N‐, and O‐nucleophilic elements furnishes the ...
