[wherein R
1
represents CONR
1a
R
1b
(wherein R
1a
and R
1b
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 R
1a
and R
1b
are combined together with the adjacent nitrogen atom thereto to form a substituted or unsubstituted heterocyclic group) or the like,
R
2
represents a hydrogen atom, CONR
2a
R
2b
(wherein R
2a
and R
2b
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 R
2a
and R
2b
are combined together with the adjacent nitrogen atom thereto to form a substituted or unsubstituted heterocyclic group), NR
2c
R
2d
(wherein R
2c
and R
2d
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].
本发明提供了一个由公式(I)表示的化合物:[其中R1表示CONR1aR1b(其中R1a和R1b可以相同或不同,每个表示氢原子,取代或未取代的较低烷基,取代或未取代的芳基,取代或未取代的芳基烷基或取代或未取代的杂环基,或R1a和R1b与相邻的氮原子结合形成取代或未取代的杂环基)或类似物,R2表示氢原子,CONR2aR2b(其中R2a和R2b可以相同或不同,每个表示氢原子,取代或未取代的较低烷基,取代或未取代的芳基,取代或未取代的芳基烷基或取代或未取代的杂环基,或R2a和R2b与相邻的氮原子结合形成取代或未取代的杂环基),NR2cR2d(其中R2c和R2d可以相同或不同,每个表示氢原子,取代或未取代的较低烷基,取代或未取代的较低烷酰基,取代或未取代的芳酰基,取代或未取代的杂环芳酰基,取代或未取代的芳基烷基磺酰基或取代或未取代的较低芳基磺酰基)或类似物]。
