AHL-dependent quorum sensing inhibition: Synthesis and biological evaluation of α-(N-alkyl-carboxamide)-γ-butyrolactones and α-(N-alkyl-sulfonamide)-γ-butyrolactones (original) (raw)

Bioorganic & Medicinal Chemistry Letters, 2011

Abstract

New N-acylhomoserine lactone (AHL) analogues in which the amide function is replaced by a reverse-amide one have been studied as AHL QS modulators. The series of compounds consists of α-(N-alkyl-carboxamide)-γ-butyrolactones, α-(N-alkyl-sulfonamide)-γ-butyrolactones, and 2-(N-alkyl-carboxamide)-cyclopentanones and cyclopentanols. Most active compounds exhibited antagonist activities against LuxR reaching the 30 μM range.
