Antiviral activity of FNC, 2'-deoxy-2'-β-fluoro-4'-azidocytidine, against human and duck HBV replication.
BACKGROUND New drugs are needed to combat HBV infection. We investigated the anti-HBV activity of the deoxycytidine analogue FNC, which has anticancer activity and has been found to inhibit HCV replication. METHODS In this study, a human hepatoma HepG2.2.15 cell culture system and duck HBV (DHBV) infection model were used as the in vitro and in vivo models to evaluate the anti-HBV activity of...
متن کاملAMG-232, a New Inhibitor of MDM-2,Enhance Doxorubicin Efficiency in Pre-B Acute Lymphoblastic Leukemia Cells
Background: Doxorubicin (DOX)-induced cardiotoxicity appears to be a growing concern for extensive use in acute lymphoblastic leukemia (ALL). The new combination treatment strategies, therefore might be an effective way of decreasing its side effects as well as improving efficacy. AMG232 (KRT-232) is a potential MDM-2 inhibitor, increasing available p53 through disturbing p53-MDM-2 interaction....
متن کاملPSI-7851, a pronucleotide of beta-D-2'-deoxy-2'-fluoro-2'-C-methyluridine monophosphate, is a potent and pan-genotype inhibitor of hepatitis C virus replication.
The hepatitis C virus (HCV) NS5B RNA polymerase facilitates the RNA synthesis step during the HCV replication cycle. Nucleoside analogs targeting the NS5B provide an attractive approach to treating HCV infections because of their high barrier to resistance and pan-genotype activity. PSI-7851, a pronucleotide of beta-D-2'-deoxy-2'-fluoro-2'-C-methyluridine-5'-monophosphate, is a highly active nu...
متن کاملTemporal organization of replication in DNA fibers of mammalian cells
The extent of coordinate control over the multiple initiation events in DNA replication has been investigated in three mammalian cell lines by DNA fiber autoradiography. Quantitative estimates have been obtained of the degree of synchrony among initiations occurring on stretches of DNA. Synchrony decreases markedly with increasing distance between initiation sites in MDBK (bovine) and L929 (mou...
متن کاملNuclear organization of DNA replication initiation proteins in mammalian cells.
Origin recognition complex (ORC), CDC6, and MCM proteins assemble sequentially to form prereplication chromatin. However, their organization remains largely unclear in mammalian cells. Here we show that ORC1 proteins are associated with non-chromatin nuclear structures and assemble in nuclear foci in mammalian cells using an in vivo chemical cross-linking method. CDC6 proteins were also found t...
