Abstract

1-beta-D-Arabinofuranosyl-E-5-(2-bromovinyl)uracil (BV-araU) and E-5-(2-bromovinyl)uracil, a metabolite of BV-araU, did not affect either the anti-human immunodeficiency virus activity or the cytotoxicity of azidothymidine in MT-4 and MOLT-4 cells. Similarly, the bromovinyl compounds did not affect the in vitro antitumor activities of arabinosylcytosine, 5-fluorouracil, and 5-fluoro-2'-deoxyuridine. The anti-varicella-zoster virus activity of BV-araU was not influenced by azidothymidine, 2',3'-didehydro-2',3'-dideoxythymidine, or arabinosylcytosine, whereas relatively high concentrations of fluorinated antitumor agents enhanced the anti-varicella-zoster virus activity.
