determined and the lipophilic character of compounds has been found to be important parameter for the observed activity of the tested benzimidazole derivatives against Moraxella catarrhalis. The indolo 2-substituted benzimidazole 13a demonstrated solid activity against Staphylococcus aureus (MICs 16 μg/mL) and Moraxella catarralis (MICs 2 μg/mL) and represents promising lead molecule for further optimization
