ABSTRACT:
The present invention aims at provision of a quinoline derivative having a neurokinin 2 (NK2) receptor antagonistic action and relates to a compound represented by the formula (I)wherein R1is a hydrogen atom and the like; R2is a hydrogen atom, a hydrocarbon group optionally having substituent(s) and the like; R3is unsubstituted (i.e., absence), a hydrogen atom and the like; R4and R5are the same or different and each is a hydrogen atom, a hydrocarbon group optionally having substituent(s), and the like; R6is (cyclic group optionally having substituent(s))-carbonyl, and the like; R7, R8, R9and R10are the same or different and each is a hydrogen atom, halogen and the like; or R7and R8, R8and R9, and R9and R10may form a ring together with the adjacent carbon atoms; n is an integer of 1 to 5;--- represents unsubstituted (i.e., absence) or a single bond; andrepresents a single bond or a double bond, or a salt thereof, and the like.
