Objective: To test the activity of a small molecule compound that targets Lipid II against Acinetobacter baumannii.
Methods: Susceptibility to small molecule Lipid II inhibitor BAS00127538 was assessed using carbapenem- and colistin-resistant clinical isolates of A. baumannii. In addition, synergy between colisitin and this compound was assessed.
Results: Small molecule Lipid II inhibitor BAS00127538 potently acts against A. baumannii and acts synergistically with colistin.
Conclusion: For the first time, a compound that targets Lipid II is described that acts against multi-drug resistant isolates of A. baumannii. The synergy with colistin warrants further lead development of BAS00127538.
Keywords: Lipid II, Acinetobacter baumannii, drug development
