It is intended to provide compounds of the following general formula (I) which are glycogen phosphorylase inhibitors and useful as remedies and preventives for insulin-dependent diabetes (type 1 diabetes), insulin-independent diabetes (type 2 diabetes), insulin resistant disease and obesity. Namely, glycogen phosphorylase inhibitors characterized by having an indole ring, etc. bonded to a ring A (an aryl ring or an aromatic heterocycle) via an amide bond and the ring A having a hydroxyethylene moiety as a substituent. It is still preferable that the glycogen phosphorylase inhibitors are characterized in that the above-described ring A has a dihydroxyethylene moiety as a substituent.
