  B-ring modified aurones as promising allosteric inhibitors of hepatitis C virus RNA-dependent RNA polymerase

  摘要：

  Following our recent report showing the potential of naturally occurring aurones (2-benzylidenebenzofuran-3(2H)-ones) as anti-hepatitis C virus (HCV) agents, efforts were continued in order to refine the structural requirements for the inhibitory effect on HCV RNA-dependent RNA polymerase (RdRp). In this study, we targeted the B-ring moiety of aurones with the aim to improve structural features associated with higher inhibition of the targeted polymerase. In vitro evaluation of the RdRp inhibitory activity of the 37 newly synthesized compounds pointed out that the replacement of the B-ring with an N-substituted indole moiety induced the highest inhibitory effect. Of these, compounds 31, 40 and 41 were found to be the most active (IC50 = 2.3-2.4 μM). Docking experiments performed with the most active compounds revealed that the allosteric thumb pocket I of RdRp is the binding pocket for aurone analogues.

  At least one aurone or a natural or synthetic derivative of aurone, or an analogue of aurone, in which the independent phenyl ring can be substituted by a heterocycle of pyrrole, imidazole, triazole, pyridine, furan, or thiophene type, is disclosed as a cosmetic agent, or as an active substance, for the manufacture either of a cosmetic composition, or of a pharmaceutical composition, notably a dermatological composition, having a melanogenesis-inhibiting activity or a depigmenting activity, or an anti-tyrosinase activity.
