Synergistic inhibition of human immunodeficiency virus type 1 replication by 5-ethyl-1-ethoxymethyl-6-(phenylthio)uracil (E-EPU) and azidothymidine in vitro

Abstract
A novel 6-substituted acyclouridine derivative, 5-ethyl-1-ethoxymethyl-6-(phenylthio)uracil (E-EPU), has recently proved to be a highly potent and selective inhibitor of human immunodeficiency virus type 1 (HIV-1) in vitro. Combinations of 3'-azido-2',3'-dideoxythymidine (AZT) and E-EPU synergistically inhibit the replication of HIV-1 in MT-4 cells, whereas the cytotoxic effects of AZT and E-EPU on mock-infected MT-4 cells are not enhanced by the drug combination. Synergistic inhibition of HIV-1 replication has also been observed in peripheral blood lymphocytes. These results indicate that the combination of AZT and E-EPU should be further pursued in the treatment of AIDS.
