The present invention provides an α2c-adrenoceptor antagonist comprising, as an active ingredient, a condensed-ring-pyrimidine derivative represented by general formula (I) below or a pharmaceutically acceptable salt thereof useful for treating and/or preventing various diseases induced by hyperactivity of α2c-adrenoceptor (for example, Parkinson's disease, L-DOPA-induced dyskinesia, tardive dyskinesia and depression) and the like.
wherein p represents an integer of 1 to 3;
R1 represents a substituted or unsubstituted heterocyclic group, substituted or unsubstituted aryl, or the like;
R2 represents -N(-R4)(-R5) (wherein R4 and R5 are the same or different, and each represents a hydrogen atom,
substituted or unsubstituted aralkyl, or the like, or R4 and R5 form a substituted or unsubstituted heterocyclic group together with the adjacent nitrogen atom) or the like; and
-Q- represents -N=C(-R7)- [wherein R7 represents -N(-R9) (-R10) (wherein R9 and R10 are the same or different, and each represents substituted or unsubstituted aralkyl, or the like, or R9 and R10 form a substituted or unsubstituted heterocyclic group together with the adjacent nitrogen atom) or the like] or the like}
本发明提供了一种α2c-肾上腺素受体拮抗剂,其活性成分包括由下式通式(I)代表的缩合环嘧啶衍生物或其药学上可接受的盐,可用于治疗和/或预防由α2c-肾上腺素受体过度活跃诱发的各种疾病(例如帕金森病、L-DOPA诱发的运动障碍、迟发性运动障碍和抑郁症)等。
其中 p 代表 1 至 3 的整数;
R1 代表取代或未取代的杂环基团、取代或未取代的芳基或类似基团;
R2 代表-N(-R4)(-R5)(其中 R4 和 R5 相同或不同,且各自代表氢原子、
取代或未取代的芳基或类似物,或 R4 和 R5 与邻近的氮原子一起形成取代或未取代的杂环基团)或类似物;以及
-Q-代表-N=C(-R7)-[其中 R7 代表-N(-R9)(-R10)(其中 R9 和 R10 相同或不同,各自代表取代或未取代的芳烷基或类似物,或 R9 和 R10 与邻近的氮原子一起形成取代或未取代的杂环基团)]或类似物}。
