(+)-Rutamarin inhibits EBV lytic DNA replication with an IC50 of 7.0 μM. (-)-Chalepin, a (-)-rutamarin derivative, was isolated from the whole plant of Ruta graveolens and used as a precursor of (-)-rutamarin. Altogether, 28 (-)-rutamarin derivatives were synthesized starting from (-)-chalepin. Of these, 16 compounds (2a-e, 3b-e, 3g, 4f, 4k, 4m-p) were found to be more potent against EBV lytic DNA replication than (-)-chalepin. Compounds 4m, 4n, and 4p exhibited IC50 values of 1.5, 0.32, and 0.83 μM and showed selectivity index values (SI) of 801, 211, and >120, respectively. Thus, compounds 4m, 4n, and 4p are considered promising leads for further laboratory investigation.

Herpesviruses require several cellular proteins for their lytic DNA replication including topoisomerase II (Topo II). Thus, Topo II could be an effective drug target against herpesviral infection. In this study, we examined several Topo II catalytic inhibitors for their potentials in blocking EBV replication and becoming efficacious antiviral agents. Topo II catalytic inhibitors in general exhibited marked inhibition of EBV lytic replication and minimal cytotoxicity. In particular, (+)-rutamarin, with the best selectivity index (SI>63) among the inhibitors tested in this study, is effective in inhibiting EBV DNA replication and virion production but shows little adverse effect on cell proliferation, suggesting its potential to become an efficacious and safe drug for the treatment of human diseases associated with EBV infection.

Kaposi’s sarcoma-associated herpesvirus (KSHV) is an etiological agent of several AIDS-associated malignancies, including Kaposi’s sarcoma (KS), primary effusion lymphoma (PEL), and multicentric Castleman’s disease (MCD). Its lytic replication cycle has been proven to be critical for the pathogenesis of KSHV-associated diseases. In KS lesions, lytic viral replication, production of virion particles, and reinfection of endothelial cells are essential to sustain the population of infected cells that otherwise would be quickly lost as spindle cells divide. Thus, antivirals that block KSHV replication could be a strategy in the treatment of KSHV-associated diseases. However, there is no effective anti-KSHV drug currently available. Our previous work showed that human topoisomerase II (Topo II) is indispensable for KSHV lytic replication and is suggested to be an effective target for antiviral drugs. Here, we report the discovery and characterization of a novel catalytic inhibitor of human Topo IIα, namely, (+)-rutamarin. The binding mode of (+)-rutamarin to the ATPase domain of human Topo IIα was established by docking and validated by molecular dynamics (MD) simulations. More importantly, (+)-rutamarin efficiently inhibits KSHV lytic DNA replication in BCBL-1 cells with a half-maximal inhibitory concentration (IC50) of 1.12 μM and blocks virion production with a half-maximal antiviral effective concentration (EC50) of 1.62 μM. It possesses low cytotoxicity, as indicated by the selectivity index (SI) of 84.14. This study demonstrated great potential for (+)-rutamarin to become an effective drug for treatment of human diseases associated with KSHV infection.
