BAY-57-1293 is a potent helicase primase inhibitor. BAY-57-1293 inhibits replication of herpes simplex virus (HSV) type 1 and type 2 in the nanomolar range in vitro by abrogating the enzymatic activity of the viral primase-helicase complex. In various rodent models of HSV infection the antiviral activity of BAY-57-1293 in vivo was found to be superior compared to all compounds currently used to treat HSV infections. The compound shows profound antiviral activity in murine and rat lethal challenge models of disseminated herpes, in a murine zosteriform spread model of cutaneous disease, and in a murine ocular herpes model. It is active in parenteral, oral, and topical formulations.

How to use
BAY-57-1293 is the first in a class of antiviral agents that inhibit HSV replication by targeting the viral helicase-primase enzyme complex. BAY-57-1293 (0.03-45 mg/kg) significantly increases survival. BAY-57-1293 (0.3-30 mg/kg) reduces mortality against HSV-1, E-377. BAY-57-1293 has potent and resistance-breaking antiviral efficacy with potential for the treatment of potentially life-threatening HSV type 1 and 2 infections, including herpes simplex encephalitis. Combination therapies of BAY-57-1293 at 0.1 or 0.3 mg/kg/dose with Acyclovir (10 mg/kg/dose) are protective when compared to the vehicle treated group against HSV-2, strain MS.
