Patent number: 7572459Abstract: To inhibit, prophylactically or therapeutically, a bacterial, yeast, fungal, or parasitic agent in a patient, an effective amount of a dendrimer is administered to the patient, which dendrimer has a plurality of terminal groups, at least one of which has an anionic- or cationic-moiety covalently bonded or linked thereto. The anionic-containing moiety is not a disaccharide or oligosaccharide moiety, and, where the anionic-containing moiety is a neuraminic- or sialic acid-containing moiety, it is modified in the 4-position by substitution with an amino, amido, cyano, azido or guanido group, or is unsaturated.Type: GrantFiled: August 26, 2002Date of Patent: August 11, 2009Assignee: Starpharma Pty Ltd.Inventors: Barry Ross Matthews, George Holan
