This invention relates to a compound represented by the formula:
wherein B represents a hydrogen atom or a lower alkyl group; ring A represents a benzene ring which may have one or more substituents;
represents a single or double bond; Q₁ represents the group represented by the formula,
, or a hydrocarbon residue substituted with the group represented by the formula,
wherein X represents a bond or a spacer having a chain length of 1 to 4 atoms as the linear moiety which may have one or more side chains; R¹ and R², whether identical or not, independently represent a hydrogen atom or a lower alkyl, or may bind together to form a ring; Q₂ represents a hydrogen atom, a hydrocarbon residue which may be substituted or a heterocyclic ring residue which may be substituted; or a salt thereof.
本发明涉及一种由式表示的化合物:
其中 B 代表氢原子或低级烷基;环 A 代表苯环,该苯环可以有一个或多个取代基;
代表单键或双键;Q₁ 代表由式表示的基团、
或被式中所代表的基团取代的烃残基、
其中,X 代表键或链长为 1 至 4 个原子的间隔物,作为可具有一个或多个侧链的线性分子;R¹ 和 R²,无论是否相同,独立地代表氢原子或低级烷基,或可结合在一起形成环;Q₂ 代表氢原子、可被取代的烃残基或可被取代的杂环残基;或其盐。
