2-Aminoimidazoles Inhibit Mycobacterium abscessus Biofilms in a Zinc-Dependent Manner

INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES, 23(6).

By: J. Belardinelli *, W. Li *, K. Martin *, M. Zeiler *, E. Lian *, C. Avanzi *, C. Wiersma*, T. Nguyen n ...

author keywords: Mycobacterium abscessus; nontuberculous mycobacteria; biofilm; 2-aminoimidazoles; zinc
MeSH headings : Anti-Bacterial Agents / pharmacology; Biofilms; Humans; Imidazoles / pharmacology; Microbial Sensitivity Tests; Mycobacterium Infections, Nontuberculous; Mycobacterium abscessus; Zinc / pharmacology
TL;DR: Preliminary mechanistic studies indicate that AB-2-29 acts through a distinct mechanism from those reported to date for 2-aminoimidazole compounds, and its antibiofilm activity is potentiated by the addition of zinc to the culture medium. (via Semantic Scholar)

Identification of Anti-Mycobacterial Biofilm Agents Based on the 2-Aminoimidazole Scaffold

CHEMMEDCHEM, 14(9), 927–937.

By: T. Nguyen  n, B. Minrovic*, R. Melander* & C. Melander*

author keywords: 2-aminoimidazoles; biofilms; mycobacteria; synergy; tuberculosis
MeSH headings : Animals; Antitubercular Agents / chemistry; Antitubercular Agents / pharmacology; Biofilms / drug effects; Imidazoles / chemistry; Male; Mice; Microsomes / drug effects; Microsomes / metabolism; Mycobacterium tuberculosis / drug effects
TL;DR: Using Mycobacterium smegmatis as a surrogate organism, the identification of two new 2‐aminoimidazole compounds are reported that inhibit and disperse mycobacterial biofilms, work synergistically with isoniazid and rifampicin to eradicate preformed M.’smegmatisBiofilms in vitro, are nontoxic toward Galleria mellonella, and exhibit stability in mouse plasma.

2018 journal article

2-Aminobenzimidazoles as antibiofilm agents against Salmonella enterica serovar Typhimurium

MEDCHEMCOMM, 9(9), 1547–1552.

By: W. Huggins n, T. Nguyen  n, N. Hahn n, J. Baker n, L. Kuo *, D. Kaur*, R. Melander  n, J. Gunn *, C. Melander  n

TL;DR: Modifications to the head, tail, and linker regions of the original hit compound elucidated new, more effective analogues that inhibit S. enterica serovar Typhimurium biofilm formation while being non-toxic to planktonic bacterial growth. (via Semantic Scholar)
