Antiviral agents in hepatitis B virus transfected cell lines: inhibitory and cytotoxic effect related to time of treatment

Abstract: The antiviral and cytotoxic effects of ara-arahinoside monophosphate, 2',3', dideoxy-cytidine, ganciclovir, 9-2(-phosphonyhnethoxyethyl) adenine, 2',3'dideoxy3'-thiacytidine and recombinant interferon-alpha were studied using two human hepatitis B virus transfected hepatoma cell lines, HepGZ 2.2.15 and HB 611. After 9 days of exposure, starting on day 3 after seeding, inhibition of extracellular HBV-DNA expressed as IDss was in the 0.1-1.0 /cM range for 2',3'-dideoxy3'-thiacytidine and 9-Z(-phosphonyhuethoxyet… Show more

“…Our results demonstrated a greater suppression of DHBV replication by adefovir than by lamivudine, in agreement with previous data obtained with avian cells transfected with the DHBV genome (42). On the other hand, lamivudine was shown to be as effective as or more effective than adefovir in human hepatoma cell lines transfected with the HBV genome (14,24,39). These differences in activity may reflect differences between the species of hepadnavirus and of the cell type.…”

“…The procedure of CEM cell infection with mutant HIV-1 strains, preparation of the samples for PCR assays, amplification of the proviral DNA, and sequencing of the 727 bp fragment covering amino acid residues 50-270 have been reported earlier (11,14). The first set of primers (5-GTAGAATTCTGTTGACTCAGATTGG-3 and 5-TTCTGCCAGTTCTAGCTCTGCTTCT-3) gave a 900-bp product of the proviral RT gene.…”

“…The routine approach for screening compounds to treat HBV infection is based on their inhibitory activities against HBV-DNA production and antigen expression [30,31] . In this study, the anti-HBV activities of traditional Chinese medicine R. palmatum L. ethanol extract (RPE) and isolated compounds were evaluated using HepG2 2.2.15 cell line as a model.…”
