| Description | Majoranaquinone demonstrates potent antibacterial activity against four Staphylococcus strains, one Moraxella strain, and one Enterococcus strain. It also acts as an effective efflux pump inhibitor in Escherichia coli ATCC 25922 and inhibits biofilm formation on both E. coli ATCC 25922 and E. coli K-12 AG100 [1]. |
| In vitro | Majoranaquinone (compound 1) demonstrated significant antibacterial effects at concentrations ranging from 0.195 to 100 mM after 20 hours of exposure against four Staphylococcus strains, one Moraxella, and one Enterococcus [1]. Furthermore, when tested at 62.5-1000 μM over 48 hours, Majoranaquinone exhibited potent inhibitory activity against the efflux pump in Escherichia coli ATCC 25922 [1]. Additionally, at the same concentrations and duration, Majoranaquinone acted as an effective biofilm formation inhibitor in both E. coli ATCC 25922 and E. coli K-12 AG100 strains [1]. |
