D13-9001 is a small-molecule inhibitor of RND-family bacterial efflux pump subunits AcrB (AcrAB-TolC) and MexB (MexAB-OprM). It shows binding affinities (KD ≈ 1.15 μM for AcrB and 3.57 μM for MexB) and is used in microbiology research to study efflux-mediated antibiotic resistance and to potentiate antimicrobial agents in vitro. The compound is supplied as a high-purity solid suitable for biochemical and cellular assays.

• Potent inhibitor of AcrB and MexB efflux pump subunits.
• Measured KD values near 1.15 μM (AcrB) and 3.57 μM (MexB).
• High reported purity suitable for biochemical assays.
• Solid small-molecule formulation amenable to in vitro testing.
• Useful for research on efflux-mediated antibiotic resistance and potentiation assays.
