Coumarins Disrupt Cell–Cell Communication and Virulence in Priority Pathogens: Targeting the PQS Signalling System in Pseudomonas aeruginosa

open access: yesMicrobial Biotechnology, Volume 19, Issue 7, July 2026.
The selective nature through which coumarin compounds produced by different species of plants target PQS signalling in Pseudomonas aeruginosa and select for distinct phenotypic responses in key pathogenic organisms adds to the growing evidence of their utility as natural virulence suppressors. ABSTRACT Cell‐to‐cell communication in microbial systems is

Alkyl Arylacetates in Cascade Reactions with 2‐Cyanobenzaldehydes for the Synthesis of 3‐Substituted Isoindolinones

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
Effective synthesis of 3‐substituted isoindolinones is possible through novel cascade reactions of alkyl arylacetates with 2‐cyanobenzaldehydes under mild, basic conditions. Herein we report the use of alkyl arylacetates as pro‐nucleophiles in cascade reactions with 2‐cyanobenzaldehydes leading to the formation of novel 3‐substituted isoindolinones, a ...
