The present invention provides a compound represented by the formula (I):
wherein
ring A is a ring which is optionally further substituted;
R1 is a hydrogen atom or a substituent;
R2 is a hydrogen atom or a substituent;
R3 is a hydrogen atom or a substituent;
R4 is a hydrogen atom or a substituent;
R5 is a hydrogen atom or a substituent;
R6 is a hydrogen atom or a substituent;
X is =N- or =C(Z)- (Z is a hydrogen atom or a substituent);
when X is =C(Z)-, Z and R6 are optionally bonded to each other to form, together with the carbon atom bonded thereto, an optionally substituted ring,
provided that when X is =CH-, then R6 is not optionally substituted 2-piperidinyl, excluding N-imidazo[1,2-a]pyridin-2-yl-4-methyl-benzamide, N-imidazo[1,2-a]pyridin-2-yl-benzamide and N-(7-methylimidazo[1,2-a]pyridin-2-yl)-benzamide, or a salt thereof, and a pharmaceutical agent containing same. The compound of the present invention has an ASK1 inhibitory action, and is useful as a pharmaceutical agent such as an agent for the prophylaxis or treatment of diabetes, inflammatory diseases and the like, and the like.
本发明提供了一种由式 (I) 表示的化合物:
其中
环 A 是任选被进一步取代的环;
R1 是氢原子或取代基
R2 是氢原子或取代基
R3 是氢原子或取代基
R4 是氢原子或取代基
R5 是氢原子或取代基
R6 是氢原子或取代基;
X是=N-或=C(Z)-(Z是氢原子或取代基);
当 X 为 =C(Z)-时,Z 和 R6 可选择相互键合,与其键合的碳原子一起形成一个可选择取代的环、
但当 X 为 =CH-时,则 R6 不是任选取代的 2-哌啶基,不包括 N-咪唑并[1,2-a]吡啶-2-基-4-甲基苯甲酰胺、N-咪唑并[1,2-a]吡啶-2-基苯甲酰胺和 N-(7-甲基咪唑并[1,2-a]吡啶-2-基)-苯甲酰胺或其盐,以及含有相同成分的药剂。本发明的化合物具有抑制 ASK1 的作用,可用作药物制剂,如预防或治疗糖尿病、炎症性疾病等的药物。
