To provide a central nervous system tissue-labeling composition labeling the central nervous tissue system. Also, another object of the present invention is to provide a method for non-invasively labeling the central nervous tissue system. Further, another object of the present invention is to provide a screening method using the above central nervous system tissue-labeling composition. A central nervous system tissue-labeling composition containing, as an active ingredient, at least one of compounds represented by the general formula (1) or (7).
Various conjugated compounds containing a coumarin moiety and a heterocyclic nucleus were synthesized. Their activity against hepatitis C virus was tested on subgenomic replicon replication in Huh 5-2 cells. Some heterobicycle-coumarin conjugates with the -S-CH2-linker were found to possess appealing antiviral activities. The sulfur atom in these conjugated compounds was found to be an essential element to their antiviral activity.
