In vitro antiviral efficacy of mycophenolic acid against hepatitis B virus / 中华传染病杂志

ABSTRACT

Objective To evaluate the in vitro inhibitive activities of mycophenolic acid against hepatitis B virus in vitro. Methods The different concentrations of the test drugs in DMEM were added to the well with the monolayer growth of HepG2.2.15 cells. The culture medium was refreshed with DMEM containing the appropriate drugs every 3 days. At 3rd, 6th and 9th days, the supernatant was collected for HBsAg quantitative assay, total RNA was isolated from cells for RT-PCR and realtime-PCR assays. Results It was found no significant anti-HBV effect of mycophenolic acid on concentration of 2～250 ?g/ml, and mini inhibitory efficacy of HBV replication on concentration of 1250 ?g/ml. There was significant anti-HBV effect of lamivudine on concentration of 5 ?g/ml. When combined with lamivudine mycophenolic acid can significantly potentiate anti-HBV activities of lamivudine, and it can get maximal inhibition effect on concentration of 10 ?g/ml. Conclusions Mycophenolic acid could inhibit HBV replication and potentiate anti-HBV activities of lamivudine.
