Antibiofilm Activity of a Diverse Oroidin Library Generated through Reductive Acylation

Abstract

A diverse 20-compound library of analogues based on the marine alkaloid oroidin were synthesized via a reductive acylation strategy. The final target was then assayed for inhibition and dispersion activity against common proteobacteria known to form biofilms. This methodology represents a significant improvement over the generality of known methods to acylate substrates containing 2-aminoimidazoles and has the potential to have broad application to the synthesis of more advanced oroidin family members and their corresponding analogues.
