A native mass spectrometry-based approach was developed to quantify the monomer-dimer equilibrium of the LPS transport protein LptH, leading to the identification of quinoline-based hit compounds for the development of novel LPS transport inhibitors. This method also provided new insights into the structure-activity relationships of antimicrobial peptides and small molecule disruptors.
We developed a native mass spectrometry-based approach to quantify the monomer-dimer equilibrium of the LPS transport protein LptH. We use this method to assess the potency and efficacy of an antimicrobial peptide and small molecule disruptors, obtaining new information on their structure-activity relationships. This approach led to the identification of quinoline-based hit compounds representing the basis for the development of novel LPS transport inhibitors.
