RESUMO

Acyclovir diphosphate dimyristoylglycerol (ACVDP-DG) is a lipid prodrug which is active against ACV-resistant strains of herpes simplex virus because of its intracellular metabolism to ACV monophosphate. In human cytomegalovirus (HCMV)-infected MRC-5 cells, ACVDP-DG was ninefold more active than ACV. When liposomal [8-3H]ACVDP-DG was injected intravitreally at the maximum nontoxic dose of 1 mumol in rabbits, the drug remained above its estimated 90% HCMV-inhibitory concentration for 18 days. Intravitreal ganciclovir persists above its 90% inhibitory concentration for only 1 to 2 days. ACVDP-DG may be useful as a local treatment for HCMV retinitis.
