Abstract：
:Citrusinine-I, a new acridone alkaloid isolated from the root bark of the citrus plant (Rutaceae), exhibited potent activity against herpes simplex virus (HSV) type 1 and type 2 at low concentrations relative to their cytotoxicity; 50% effective concentrations (ED50) of citrusinine-I were 0.56 micrograms/ml and 0.74 micrograms/ml against HSV-1 and HSV-2, respectively. Inhibitory action was also demonstrated against cytomegalovirus (CMV) and thymidine kinase-deficient or DNA polymerase mutants of HSV-2. The compound markedly suppressed HSV-2 and CMV DNA synthesis at concentrations which did not inhibit the synthesis of virus-induced early polypeptides. However, citrusinine-I had no inhibitory activity against HSV and CMV DNA polymerases in cell-free extracts. Although the target of this inhibitor remains to be elucidated, the most plausible candidate is a virus-coded ribonucleotide reductase. Citrusinine-1, when combined with acyclovir or ganciclovir, synergistically potentiated the antiherpetic activity of these agents. Based on a comparative study of the antiherpetic activity of citrusinine-1 and 28 related compounds, a structure-activity relationship could be established.
