AB The antiviral activity of water-soluble dextrans derivatized with
varying percentages of carboxymethyl, benzylamide, and sulfonate groups
was evaluated. Several of the polymers exhibited potent antiviral
activity against a variety of enveloped viruses, but not against
non-enveloped viruses, and only when present during virus adsorption.
The mechanism of activity against retroviruses [i.e. human
immunodeficiency virus (HIV)] and herpes viruses (i.e. human
cytomegalovirus) could be ascribed to inhibition of virus binding to the
cells. An absolute requirement for anti-HSV activity appeared to be a
sufficiently high percentage of benzylamide and benzylamide sulfonate
groups. This did not, however, apply for human cytomegalovirus,
respiratory syncytial virus, and HIV. The sensitivity of the latter
viruses appeared to be influenced by factors other than the global
chemical composition, which leads us to assume that physical factors
such as the distribution and sequence of the substituents on the sugar
backbone play an important role in the antiviral activity of the
derivatized dextrans.
