The present invention provides a compound represented by Formula (I):
[whetein R1 represents CONR1aR1b (wherein R1a and R1b may be the same or different and each represents a hydrogen atom, substituted or unsubstituted lower alkyl, substituted or unsubstituted aryl, substituted or unsubstituted ararkyl or a substituted or unsubstituted heterocyclic group, or R1a and R1b are combined together with the adjacent nitrogen atom thereto to form a substituted or unsubstituted heterocyclic group) or the like,
R2 represents a hydrogen atom, CONR2aR2b (wherein R2a and R2b may be the same or different and each represents a hydrogen atom, substituted or unsubstituted lower alkyl, substituted or unsubstituted aryl, substituted or unsubstituted ararkyl or a substituted or unsubstituted heterocyclic group, or R2a and R2b are combined together with the adjacent nitrogen atom thereto to form a substituted or unsubstituted heterocyclic group), NR2cR2d (wherein R2c and R2d may be the same or different and each represents a hydrogen atom, substituted or unsubstituted lower alkyl, substituted or unsubstituted lower alkanoyl, substituted or unsubstituted aroyl, substituted or unsubstituted heteroaroyl, substituted or unsubstituted ararkyl, substituted or unsubstituted lower alkylsulfonyl or substituted or unsubstituted lower arylsulfonyl) or the like].
本发明提供了一种由式 (I) 表示的化合物:
[式中R1代表CONR1aR1b(其中R1a和R1b可以相同或不同,各自代表氢原子、取代或未取代的低级烷基、取代或未取代的芳基、取代或未取代的芳烷基或取代或未取代的杂环基,或R1a和R1b与其相邻的氮原子结合在一起形成取代或未取代的杂环基)或类似物、
R2 代表氢原子、CONR2aR2b(其中 R2a 和 R2b 可以相同或不同,且各自代表氢原子、取代或未取代的低级烷基、取代或未取代的芳基、取代或未取代的芳烷基或取代或未取代的杂环基团,或 R2a 和 R2b 与其相邻的氮原子结合在一起形成取代或未取代的杂环基团)、NR2cR2d(其中 R2c 和 R2d 可以相同或不同,各自代表氢原子、取代或未取代的低级烷基、取代或未取代的低级烷酰基、取代或未取代的芳酰基、取代或未取代的杂芳酰基、取代或未取代的芳烷基、取代或未取代的低级烷磺酰基或取代或未取代的低级芳磺酰基)或类似物]。
