Membrane-Permeabilizing Activity of Reverse-Amide 2-Aminoimidazole Antibiofilm Agents Against Acinetobacter baumannii

CURRENT DRUG DELIVERY, 12(2), 223–230.

By: S. Stowe*, R. Thompson*, L. Peng*, Z. Su*, M. Blackledge*, G. Draughn, W. Coe, E. Johannes* ...

author keywords: 2-aminoimidazole; Acinetobacter baumannii; biofilm; membrane permeabilization; reverse amide; SEM
MeSH headings : Acinetobacter baumannii / drug effects; Amides / chemistry; Anti-Bacterial Agents / chemistry; Anti-Bacterial Agents / pharmacology; Biofilms / drug effects; Cell Membrane Permeability / drug effects; Cells, Cultured; Cross Infection; Imidazoles / chemistry; Imidazoles / pharmacology; Microbial Sensitivity Tests
TL;DR: A model is proposed that describes how the structure of RA-2AI allows it to insert itself into and disrupt the fluidity of the membrane, creating an opportunity for increased molecular permeability. (via Semantic Scholar)

Identification of BfmR, a Response Regulator Involved in Biofilm Development, as a Target for a 2-Aminoimidazole-Based Antibiofilm Agent

BIOCHEMISTRY, 51(49), 9776–9778.

By: R. Thompson n, B. Bobay n, S. Stowe n, A. Olson n, L. Peng n, Z. Su n, L. Actis *, C. Melander n, J. Cavanagh n

MeSH headings : Acinetobacter baumannii / drug effects; Acinetobacter baumannii / growth & development; Bacterial Proteins / chemistry; Bacterial Proteins / physiology; Biofilms / drug effects; Imidazoles / pharmacology; Microscopy, Confocal; Models, Molecular
TL;DR: The 2AI compound studied here represents a unique small molecule scaffold that targets bacterial response regulators and is cell permeable, while pull-down assays identified BfmR, a response regulator that is the master controller of biofilm formation, as a target for this compound.
