Synthesis and antiviral activity of coumarin derivatives against infectious hematopoietic necrosis virus

Infectious hematopoietic necrosis virus (IHNV) is a highly contagious disease of juvenile salmonid species. However, robust anti-IHNV drugs currently are extremely scarce. For the purpose of seeking out anti-IHNV drugs, here a total of 24 coumarin derivatives are designed, synthesized and evaluated for their anti-viral activities. By comparing the half maximal inhibitory concentrations (IC50) of the 12 screened candidate drugs in epithelioma papulosum cyprini (EPC) cells infected with IHNV, the imidazole coumarin derivative C4 is selected for additional validation studies, with an IC50 of 2.53 ?M at 72 h on IHNV glycoprotein. Further experiments revealed that C4 could significantly inhibit apoptosis and cellular morphological damage induced by IHNV. On account of these findings, derivative C4 could be a viable way of controlling IHNV and considered as a promising lead compound for the development of commercial drugs.
