The present invention provides a compound represented by the following formula (I): wherein: Ring A represents an optionally substituted piperazine ring, an optionally substituted morpholine ring, or an optionally substituted bromopiperazine ring; R
1
and R
2
are the same or different from each other, and represent a hydrogen atom or optionally substituted lower alkyl; R
3
and R
4
are the same or different from each other, and represent a hydrogen atom or halogenated or non-halogenated lower alkyl; R
3
to R
7
are the same or different from each other, and represent a hydrogen atom, hydroxy, optionally substituted lower alkyl, optionally substituted lower alkenyl, optionally substituted lower alkoxy, optionally substituted cycloakyl, optionally substituted aryl, an optionally substituted aromatic heterocyclic ring, optionally substituted amino, or acyl; and represents a single bond or double bond, wherein R
2
and R
3
do not exist when carbon atoms respectively adjacent to R
2
: and R
3
form a double bond, and there is no case where all of R
1
to R
7
are hydrogen atoms, and R
1
and R
2
; may form a ring together with an adjacent carbon atom; or a salt thereof.
本发明提供了以下式(I)所表示的化合物:其中:环A表示可选取代的哌嗪环、可选取代的吗啡环或可选取代的溴代哌嗪环;R1和R2相同或不同,表示氢原子或可选取代的较低烷基;R3和R4相同或不同,表示氢原子或卤代或非卤代的较低烷基;R3到R7相同或不同,表示氢原子、羟基、可选取代的较低烷基、可选取代的较低烯基、可选取代的较低烷氧基、可选取代的环烷基、可选取代的芳基、可选取代的芳香族杂环环、可选取代的氨基或酰基;表示单键或双键,其中当R2和R3分别相邻的碳原子形成双键时,R2和R3不存在,且不存在R1到R7全为氢原子的情况,R1和R2可以与相邻碳原子共同形成环;或其盐。
