bind and neutralize bacterial lipopolysaccharides. These compounds reduce lethality in a murine model of lipopolysaccharide-induced shock, and may serve as novel leads for developing novel anti-lipopolysaccharide agents for the therapy of Gram-negative sepsis. These compounds are represented by the formula:
