Novel cycloalkane carboxamide derivatives having an action that selectively inhibits cathepsin K, and a production process thereof, are provided.
A cycloalkane carboxamide derivative represented by the following general formula (I), or a pharmaceutically acceptable salt thereof:
(wherein R
1
and R
2
represent (substituted) alkyl groups, (substituted) alkenyl groups, (substituted) alkynyl groups, (substituted) aromatic hydrocarbon groups or (substituted) heterocyclic groups, ring A represents an alkylidene group having 5 to 7 carbon atoms, and ring B represents a formyl group or a hydroxymethyl group).
