Abstract     Peptidic lipopolysaccharide (LPS) antagonists are the subject of intensive research. We report an NMR and modeling study of LBP-14 (RVQGRWKVRASFFK), a synthetic fragment of the LPS binding protein (LBP). In a mixture with LPS we observed the transferred nuclear Overhauser effect and determined the LPS-bound structure of LBP-14 that was used for docking calculations to LPS. The derived complex was used to design a peptide that displayed more than 50% increase in LPS inhibition in vitro.
