Abstract
The present invention describes the ability of synthetic cationic amphiphilic molecules to bind and sequester bacterial lipopolysaccharides and other microbial products that share structural and/or physical-chemical properties with those of LPS. Such cationic amphiphilic molecules have a molecular structure comprised of a linear or branched backbone derived from polymethylenes or alkylamines which bear at the termini two or more protonatable positively charged groups derived from primary-amino. imidazolinium, or N, N'-unsubstituted amidinium or guanidium functions. They also possess one or more lipophilic groups derived from fatty acids or hydrocarbon substituents, attached to the backbone via amide, ester, carbamate, or urethane linkages. The use of these compounds provide low cost, effective therapeutic method for the treatment of sepsis and septic shock.
