The present invention aims to provide a novel SCD inhibitor.
The present invention relate to SCD inhibitor comprising A compound represented by the formula (I)
wherein
R is an optionally substituted cyclic group or an optionally substituted carbamoyl group, provided that R is not an optionally substituted 7-pyrido[2,3-d]pyrimidyl group;
ring A is an optionally further substituted pyridazine ring;
R1, R2, R3, R4, R11, R12, R13 and R14 are each independently a hydrogen atom or a substituent, or R1 and R11 in combination, R2 and R12 in combination, R3 and R13 in combination, or R4 and R14 in combination optionally form an oxo group, or R2 and R4 in combination optionally form a bond or an alkylene cross-linkage;
m and n are each independently an integer of 0 to 2;
ring B is an optionally substituted ring, provided that the two atoms constituting ring B, which are adjacent to the spiro carbon atom, are not oxygen atoms at the same time,
or a salt thereof, or a prodrug thereof.
本发明旨在提供一种新型SCD抑制剂。本发明涉及一种包括式(I)所表示的化合物的SCD抑制剂,其中R是一个可选取的取代环基团或可选取的取代的氨基甲酰基基团,但R不能是一个可选取的取代的7-吡啶并[2,3-d]嘧啶基团;环A是一个可选取的进一步取代的吡啶并咪唑环;R1、R2、R3、R4、R11、R12、R13和R14各自独立地是氢原子或取代基,或者R1和R11组合、R2和R12组合、R3和R13组合、或R4和R14组合可以选择形成一个氧代基,或R2和R4组合可以选择形成一个键或一个烷基交联;m和n各自独立地是0到2的整数;环B是一个可选取的取代环,但构成环B的两个相邻于螺碳原子的原子不同时为氧原子;或其盐或前药。
