Abstract:
A comblike surfactant polymer comprising:a) a polymeric backbone of repeating monomeric units; b) a plurality of hydrophobic side chains comprising from about 2 to about 18 methylene groups, said plurality of hydrophobic side chains being linked to said polymeric backbone by ester linkages, secondary amine linkages, amide linkages, or combinations thereof; and c) a plurality of hydrophilic side chains linked to said polymeric backbone by ester linkages, secondary amine linkages, amide linkages, or combinations thereof, said hydrophilic side chains selected from the group consisting of: neutral oligosaccharide side chains having a weight average molecular weight of less than 7000; charged oligosaccharide side chains having a weight average molecular weight of less than 10,000; an oligopeptide of from about 3 to 30 amino acid residues, said oligopeptide having an amino acid sequence which interacts with protein receptors on the surface of cells; and combinations thereof.
