Abstract
Chinese hamster ovary cells cultured in the presence of phenethyl alcohol exhibit obvious changes in cell surface galactose and galactosamine glycoproteins as determined by the galactose-oxidase[3H]borohydride technique and SDS gel electrophoresis. Cells pretreated with phenethyl alcohol (drug was removed before infection) were not as effective as hosts for vesicular stomatitis virus as untreated cultures. A minimum pretreatment time with 0.1% phenethyl alcohol of about 8 h was required before a reduction in virus growth was observed. It is proposed that phenethyl alcohol pretreatment as outlined in this report leads to a modification of the host cellular membrane resulting in the inhibition of virus replication.
