 AB    Vesnarinone is a novel synthetic oral inotropic agent that has been
       successfully used for treatment of patients with congestive heart
       failure. In addition to its cardiotonic activity, the drug has been
       proposed to have mild cytostatic and anti-HIV-1 effects. We have
       observed that vesnarinone profoundly inhibits radiolabeled thymidine and
       uridine incorporation into cells despite its modest inhibitory effect on
       DNA synthesis, RNA synthesis or cell proliferation. Here we demonstrate
       that vesnarinone inhibits both nucleoside and nucleobase transport in
       mammalian cells. This pharmacological action may be involved in some of
       its multiple biological effects.
