Amphotericin B methyl ester is a polyene antiviral and antifungal agent and a derivative of amphotericin B .1,2 It impairs viral particle production, as well as viral entry and infectivity, in HIV-1-infected TZM-bl cells when used at a concentration of 10 ?M.1 Amphotericin B methyl ester also inhibits replication of HIV-1 clinical isolates from a variety of clades in infected human peripheral blood mononuclear cells (PBMCs; IC50s = 0.5-5.5 ?M). It is active against S. cerevisiae (MIC = 0.25 ?g/ml) and reduces mortality in a mouse model of C. albicans infection when administered at doses of 1 and 10 mg/kg.2
