Abstract
Retroviruses depend on a virus-encoded proteinase. As this enzyme is an interesting target for antiviral therapy, we examined the effect of various low-molecular-weight proteinase inhibitors, as well as a few oligopeptides related to the proteolytic cleavage sites, on the replication of HIV-1 in H9 cells. The increase in reverse transcriptase activity during incubation was assumed to reflect viral replication. Cellular DNA synthesis was measured to quantitate the adverse effects of the inhibitors on the cells. Only one of the substances tested, pepstatin A, had an appreciable selective effect on viral replication. Substances that decreased DNA synthesis generally caused an equally large decrease in reverse transcriptase activity.This publication has 32 references indexed in Scilit:
