Honokiol-Inspired Analogs as Inhibitors of Oral Bacteria

ACS Infect Dis. 2018 Feb 9;4(2):118-122. doi: 10.1021/acsinfecdis.7b00178. Epub 2017 Dec 13.

Abstract

The oral microbiome is a complex ecological niche where both commensal and pathogenic bacteria coexist. Previous reports have cited that the plant isolate honokiol is a potent inhibitor of S. mutans biofilms. Herein we report a cross-coupling method that provides access to a concise library of honokiol-inspired analogs. Through this work we determined that the inhibitory activity of honokiol is highly dependent on the growth conditions. Further, we identify a series of analogs that display significant potency against oral bacteria leading to the discovery of a potent antimicrobial.

Keywords: antibiotic; natural product; oral microbiome; oxidative coupling.
