The microbiome has a fundamental impact on the human host's physiology through the production of highly reactive compounds that can lead to disease development. One class of such compounds are carbonyl-containing metabolites, which are involved in diverse biochemical processes. Mass spectrometry is the method of choice for analysis of metabolites but carbonyls are analytically challenging. Herein,

AbstractA variety of aliphatic and aromatic S-esters of thiocarboxylicacids have been tested for antimicrobial activity. The relationship between the chemical structure of the compounds R1SC(O)R2 and their toxicity for microorganisms has been revealed, and the effect of various functional groups on the antimicrobial properties has been shown.

Aryl thioesters are synthesized via nickel-catalyzed carbonylation of thioacetates with aryliodides. Alkyl thioacetates undergo coupling with carbon monoxide and aryliodides to produce the desired aryl thioesters in moderate yields. This catalytic carbonylative coupling process provides a cost-effective and direct approach for the preparation of useful thioesters.
characterized, and their human glyoxalaseI (hGLO1) inhibitory activity was evaluated. Compound 10 was proved to be the effective hGLO1 inhibitor with a Ki value of 1.0 nM and the inhibition effect of compound 10 on hGLO1 was nearly ten-fold higher than that of the strongest inhibitor 2 (Ki=10.0 nM) which has been reported in the field of glutathione-type hGLO1 inhibitors. Its diethyl ester prodrug 10'

It has been found for the first time that n-alkanes and cycloalkanes (RH) can interact with elemental sulfur at approximately-20-degrees-C. These reactions go forward in the presence of aprotic organic superacids with the composition R1COBr.2AlBr3, leading to the formation of thioesters R1CO-SR in satisfactory yields.
