The present invention relates to a tetracyclic fused heterocyclic compound represented by the following formula [I]
wherein each symbol is as defined in the specification, or a pharmaceutically acceptable a salt thereof, and a hepatitis C virus (HCV) polymerase inhibitor and a therapeutic agent for hepatitis C containing this compound. The compound of the present invention shows an anti-HCV activity based on the HCV polymerase inhibitory activity, and useful as an agent for the prophylaxis or treatment of hepatitis C.
To provide a drug including a compound having an antagonistic activity with respect to EP4 receptor in preventing and/or treating the disease caused by activation of an EP4 receptor as an active ingredient. A compound represented by the general formula (I):
(wherein in the formula, all the symbols have the same meanings as those described in the description), or a pharmaceutically acceptable salt thereof is useful as a medicament component having an EP4 receptor antagonistic activity, in preventing and/or treating the disease caused by activation of an EP4 receptor.

Herein, an iridium(III)-catalysed electrooxidative intramolecular dehydrogenative C–H/N–H coupling of unprotected 2-alkenyl anilines is described. The developed method allows the synthesis of a variety of 3-substituted N–H indole scaffolds under undivided electrolytic conditions. Mechanistic studies suggest that the reaction proceeds through the electro-oxidation induced reductive elimination pathway
