Investigations of the HCV life cycle have widened the knowledge of virology, and here we discovered that two piperazinylbenzenesulfonamides inhibit HCV entry into liver cells. The entry of HCV into host cells is a complex process that is not fully understood but is characterized by multiple spatially and temporally regulated steps involving several known host factors. Through a high-content virus infection screening analysis with a library of 1,120 biologically active chemical compounds, we identified SB258585, an antagonist of serotonin receptor 6 (5-HT6), as a new inhibitor of HCV entry in liver-derived cell lines as well as primary hepatocytes. A functional characterization suggested a role for this compound and the compound SB399885, which share similar structures, as inhibitors of a late HCV entry step, modulating the localization of the coreceptor tight junction protein claudin-1 (CLDN1) in a 5-HT6-independent manner. Both chemical compounds induced an intracellular accumulation of CLDN1, reflecting export impairment. This regulation correlated with the modulation of protein kinase A (PKA) activity. The PKA inhibitor H89 fully reproduced these phenotypes. Furthermore, PKA activation resulted in increased CLDN1 accumulation at the cell surface. Interestingly, an increase of CLDN1 recycling did not correlate with an increased interaction with CD81 or HCV entry. These findings reinforce the hypothesis of a common pathway, shared by several viruses, which involves G-protein-coupled receptor-dependent signaling in late steps of viral entry.Show less >
