MBX2319
MBX2319 is an AcrB inhibitor and antibiotic efficacy restorer that potently inhibits RND-type efflux pumps of Enterobacteriaceae species. MBX2319 increases antibacterial activity of fluoroquinolone and β-lactam antibiotics against Escherichia coli, restores antibiotic efficacy, and reduces antibiotic MIC against Gram-negative bacteria. MBX2319 has no inherent antibacterial activity against Escherichia coli and does not alter bacterial outer membrane permeability. MBX2319 can be used for the research of gram-negative bacterial infections and multidrug-resistant gram-negative bacterial infections.

In Vitro
MBX2319 (3.1 μM; 24 h) inhibits RND-type efflux pumps in wild-type Escherichia coli (AB1157), potentiating the activity of Levofloxacin (HY-B0330) and Piperacillin (HY-B1923) with an MPC4 of 3.1 μM for both antibiotics, while showing no inherent antibacterial activity at concentrations up to 100 μM[1].
MBX2319 (>100 μM) is non-cytotoxic to HeLa cells, with a CC50 greater than 100 μM[1].
MBX2319 (25 μM; 60 min) is completely unstable in pooled mouse and human liver microsomes, with 0% of the compound remaining after 60 minutes of incubation at 37 °C[1].
MBX2319 (3 μM; 10 min) exhibits low inhibition of CYP450 3A4, causing 12% inhibition at a concentration of 3 μM[1].
MBX2319 binds tightly to the hydrophobic trap near the DP-AP interface of the Escherichia coli AcrB B protomer with a calculated ΔGb of -12.5 kcal/mol, closing the upper DP crevice to block substrate binding and inhibit efflux pump function[2].
