The invention discloses an application of polycyclic polyketides in preparation of an anti-HV (herpes virus) drug. It is found that the polyketides can inhibit diseases caused by infection of four HVs including HSV-1 (herpes simplex virus-1), HSV-2 (herpes simplex virus-2), VZV (varicella zoster virus) and CMV (cytomegalo virus). The compounds show equivalent activity but have different acting mechanisms as compared with commercial drugs such as acyclovir and can overcome drug resistance of existing commercial drugs. Therefore, the compounds have good application prospects in treatment of related diseases caused by infection of HVs including HSV-1, HSV-2, VZV and CMV.
