The nucleoside analogue azidothymidine (AZT) and the methyl ester of amphotericin B (AME) were assayed for antiviral effect on HIV infection singly and in combination. Both compounds were effective in inhibiting HIV infection of MT-4 cells. At concentrations where either compound alone had no significant effect on infection, the compounds in combination were potent inhibitors of HIV as evaluated by reduction in HIV antigen production and HIV induced cytopathic effect. These results indicate that a combination therapy employing compounds with different modes of action like AZT and AME may have synergistic antiviral properties. Amphotericin B itself significantly reduced HIV infectivity in vitro and should not be used as an antifungal agent in cultures intended to propagate HIV.
