independently represent a single bond, an alkylene group or a cycloalkylene group; L
2
represents a single bond, O, or NR
B
; R
B
represents H or an optionally substituted alkyl group; and R
A
represents B, an amino group, a cyano group, a hydroxy group, an alkoxy group, an aryl group, a monoalkylamino group, a dialkylamino group, a carbamoyl group, an alkyloxycarbonyl group, a monoalkylaminocarbonyl group, a dialkylaminocarbonyl group, an alkylcarbonylamino group, and a saturated heterocyclic group, among other groups.
本发明的一个主要对象是提供一种由下述通用式[1]表示的新型吡啶衍生物或其药学上可接受的盐。在式[1]中,R代表芳基或杂芳基,可以被可选择地取代的烷基、羟基、卤原子或通式[2]所代表的基团所取代。在式[2]中,-L1-L2-L3-RA[2]L1和L3独立地代表单键、烷基或环烷基;L2代表单键、O或NRB;RB代表氢或可选择地取代的烷基;RA代表B、氨基、氰基、羟基、烷氧基、芳基、单烷基氨基、双烷基氨基、氨基甲酰基、烷氧羰基、单烷基氨基羰基、双烷基氨基羰基、烷基羰基氨基和饱和杂环基等基团,以及其他基团。
