 AB    A single dose of coumarin derivatives, warfarin, 4-hydroxycoumarin and
       umbelliferone, added at the time of inoculation either by free virus or
       by contact with U1 monocytes exhibited a dose-dependent inhibitory
       effect on viral replication in target MOLT-4 lymphocytes observable even
       at 5 days post infection. In addition, marked decrease of HIV-1 gap p24
       release and reduction in reverse transcriptase activity was observed
       when chronically HIV-infected ACH-2 lymphocytes were treated with
       coumarins (ED50% range 10(-6)-10(-9) mol/l). However, the intracellular
       composition of HIV-1 core proteins in drug-exposed cells was not
       modified. Results suggest that although no complete inhibition of viral
       production has been observed in vitro this class of drugs may present
       potential interest as antiviral agents.
