  The present invention provides aromatic nitrogen-containing 6-membered ring compounds having excellent PDE10 inhibitory activity. The present invention relates to an aromatic nitrogen-containing 6-membered ring compound represented by the following formula [I 0 ] or a pharmaceutically acceptable salt thereof, a method for preparing the same, and use of said compounds for PDE10 inhibitors, and a pharmaceutical composition comprising said compounds as an active ingredient: Formula [I 0 ] wherein: X 1 , X 2 and X 3 each independently are N or CH, and at least two of X 1 , X 2 and X 3 are N; A is *—CH═CH—, *—C(Alk)=CH—, *—CH 2 —CH 2 — or *—O—CH 2 — (* is a bond with R 1 ); Alk is a lower alkyl group; Ring B is an optionally substituted nitrogen-containing aliphatic heterocyclic group; R 1 is an optionally substituted nitrogen-containing heterocyclic group, a nitrogen-containing heterocyclic moiety of which is a moiety selected from the group consisting of quinoxalinyl, quinolyl, isoquinolyl, quinazolinyl, pyrazinyl, pyrimidinyl and a moiety thereof fused with a 5 to 6-membered aliphatic ring thereto; Y 0 is a group selected from the group consisting of the following (1) to (5): (1) an optionally substituted phenyl or an optionally substituted aromatic monocyclic 5 to 6-membered heterocyclic group; (2) an optionally substituted aminocarbonyl; (3) an optionally substituted amino lower alkyl; (4) —O—R 2 wherein R 2 is hydrogen, an optionally substituted lower alkyl, lower cycloalkyl, aliphatic monocyclic 5 to 6-membered heterocyclic group, or Formula [AA]; (5) mono- or di-substituted amino; provided that, when Y 0 is mono- or di-substituted amino, the nitrogen-containing heterocyclic moiety of R 1 is not quinoxalinyl or quinolyl.

  本发明提供了具有优异的PDE10抑制活性的芳香族含氮6元环化合物。本发明涉及以下式[I0]或其药学上可接受的盐，其为一种芳香族含氮6元环化合物，以及其制备方法，用于PDE10抑制剂的化合物和包含该化合物作为活性成分的药物组合物：式[I0]其中：X1、X2和X3各自独立地为N或CH，且至少两个X1、X2和X3为N；A为*—CH═CH—、*—C(Alk)=CH—、*—CH2—CH2—或*—O—CH2—（*为R1的键）；Alk为低碳基；环B为可选取代的含氮脂肪族杂环基；R1为可选取代的含氮杂环基，其中含氮杂环基是从喹啉基、喹啉基、异喹啉基、喹唑啉基、吡嗪基、嘧啶基和它们与5至6元脂环环融合的基中选择的基；Y0为从以下组合中选择的基（1）到（5）：（1）可选取代的苯基或可选取代的芳香单环5至6元杂环基；（2）可选取代的氨基甲酰基；（3）可选取代的氨基低碳基；（4）—O—R2，其中R2为氢、可选取代的低碳基、低环烷基、脂肪单环5至6元杂环基或式[AA]；（5）单取代或双取代的氨基；但当Y0为单取代或双取代的氨基时，R1的含氮杂环基不是喹啉基或喹啉基。

  An object of the present invention is to provide to a compound and a pharmaceutical composition, which have excellent Syk-inhibitory activity. The present invention provides a nicotinamide derivative represented by the following formula (I) (wherein R 1 represents a halogen atom; R 2 represents a C 1-12 alkyl group, a C 2-12 alkenyl group, a C 2-12 alkynyl group, a C 3-8 cycloalkyl group, an aryl group, an ar-C 1-6 alkyl group or a heterocyclic group, each optionally having at least one substituent; R 3 represents an aryl group or a heterocyclic group each optionally having at least one substituent; and R 4 and R 5 each independently represent a hydrogen atom; and R 2 and R 4 may form a cyclic amino group optionally having at least one substituent together with the nitrogen atom to which they bind) or a salt thereof, and a pharmaceutical composition for use in the treatment of a Syk-related disease which comprises the nicotinamide derivative or a salt thereof.

  本发明的目的是提供一种具有优异的Syk抑制活性的化合物和制药组合物。本发明提供了一种由以下式(I)表示的烟酰胺衍生物（其中R1表示卤素原子；R2表示C1-12烷基、C2-12烯基、C2-12炔基、C3-8环烷基、芳基、芳基-C1-6烷基或杂环基，每种均可选地具有至少一个取代基；R3表示芳基或杂环基，每种均可选地具有至少一个取代基；R4和R5各自独立地表示氢原子；且R2和R4可以与它们结合的氮原子一起形成具有至少一个取代基的环状氨基团）或其盐，并且用于治疗Syk相关疾病的制药组合物包括该烟酰胺衍生物或其盐。
