  • Title: Synthesis and in vitro antimicrobial evaluation of new N-heterocyclic diquaternary pyridinium compounds.
    Author: Furdui B, Parfene G, Ghinea IO, Dinica RM, Bahrim G, Demeunynck M.
    Journal: Molecules; 2014 Aug 05; 19(8):11572-85. PubMed ID: 25100251.
    Abstract:
    A series of bis-pyridinium quaternary ammonium salts (bis-PyQAs) with different aryl and heteroaryl moieties were synthesized and their antimicrobial activity investigated. The inhibition effect of the compounds was evaluated against bacteria, molds and yeasts; the activities were expressed as the minimum inhibitory concentrations (MIC). The relationships between the structure descriptors (logP, polarizability, polar surface area (2D), van der Waals area (3D)) and the biological activity of the tested bis-PyQAs are discussed.
