The present invention relates to a novel imidazole compound or a pharmaceutically acceptable salt thereof having a melanocortin receptor agonistic activity, and medical use thereof. The present invention relates to an imidazole compound represented by general formula [I]
[wherein: Ring A represents an optionally substituted aryl group or the like; R
1
represents a hydrogen atom, an optionally substituted alkyl group, or the like; R
2
represents a hydrogen atom, a halogen atom, or the like; and R
3
represents an optionally substituted alkyl group] or a pharmaceutically acceptable salt thereof.
A novel pyrrolopyridine derivative which is a compound represented by the formula
wherein Ring A represents an optionally substituted pyridine ring; X represents an electron-attracting group; Y represents an optionally substituted divalent C
1-6
chain hydrocarbon group; R
1
represents an optionally substituted hydrocarbon group; and R
2
and R
3
each independently represents hydrogen, an optionally substituted hydrocarbon group or an optionally-substituted heterocyclic group, or R
2
and R
3
may form an optionally substituted ring in cooperation with the adjacent nitrogen atom, or a salt of the compound. The pyrrolopyridine derivative has vanilloid receptor agonist activity and is useful as medicines such as a preventive/therapeutic agent and analgesic for overactive bladder.
