Abstract: The aim of this study was to investigate whether Sofosbuvir,a small molecule drug,could inhibit the replication of Bovine viral diarrhea virus (BVDV).The effects of Sofosbuvir on the proliferation of bovine kidney cells (MDBK) at different time and concentrations were determined by MTT method.The optimal concentration of Sofosbuvir which could effectively inhibit BVDV replication was screened by immunofluorescence staining test.The effects of Sofosbuvir on BVDV replication were detected by Real-time PCR,CPE and TCID50.The results showed that Sofosbuvir treated MDBK cells for 24 and 48 h extremely significantly inhibited the proliferation of cells (P<0.01).When Sofosbuvir was 800 μmol/L,the content of double stranded RNA (dsRNA) in MDBK cells infected with BVDV was extremely significantly lower than that in the control group (P<0.01).Real-time PCR showed that compared with DMSO treatment group,the expression of BVDV 5'UTR mRNA in Sofosbuvir treated MDBK cells was extremely significantly decreased at 24 and 48 h after infection (P<0.01).The pathological changes of MDBK cells infected with Sofosbuvir were significantly reduced.Sofosbuvir treatment for 24 h extremely significantly reduced the formation and release of virus particles in the offspring of MDBK cells infected with BVDV (P<0.01).In conclusion,Sofosbuvir could effectively inhibit BVDV replication in vitro.
