MRL-494 

MRL-494, an antibacterial agent, is a inhibitor of β-barrel assembly machine A (BamA) impervious to efflux and the outer membrane permeability barrier. MRL-494 can inhibits Gram-positive (MIC of 12.5 μM for Staphylococcus aureus COL) and Gram-negative (MIC of 25 μM for E. coli JCM158) bacterias^[1].

β-barrel assembly machine A (BamA)^[1]

MRL-494 lethally disrupts the cytoplasmic membrane. MRL-494 inhibits OM proteins (OMPs) biogenesis from outside the outer membrane (OM) by targeting BamA. MRL-494 exhibits strong anti-microbial properties against both Gram-positive and Gram-negative bacteria. The MIC values of MRL-494 against E. coli (WT), E. coli (ΔtolC), E. coli (ΔtolC envA101), K. pneumonia, A. baumannii (WT), A. baumannii (ΔlpxC) , P. aeruginosa (efflux deficient), P. aeruginosa (WT), Staphylococcus aureus (methicillin-resistant) and Bacillus subtilis rpoB18 are 25 μM, 25 μM, 25 μM, 100 μM, 200 μM, 200 μM, 100 μM, 100 μM, 12.5 μM and 25 μM, respectively^[1].
