The invention relates to compounds of the general formula (I):
wherein
Ar is optionally substituted aryl or heteroaryl;
A is (i) —O—, —S—, —SO2—, —NH—, (ii) a C1-4-alkyl- or C1-6-acyl-substituted nitrogen atom or (iii) a C1-8-alkylene chain or a heteroalkylene chain having 2 to 8 chain atoms, which optionally contains at least one unsaturation, and which may be substituted and/or contain a bridge to form a saturated or partially or fully unsaturated ring having 3-8 ring members;
B is —C(R4)(R5)—, —OC(R4)(R5)—, —N(R6)C(R4)(R5)—, —N(R6)—, —O—, —S— or —SO2—;
R is optionally substituted C3-8-cycloalkyl, aryl or heteroaryl;
R1 is (i) a saturated or unsaturated azacyclic or aminoazacyclic ring, or a saturated diazacyclic or aminodiazacyclic ring, which has 4 to 7 ring members, or a saturated aminoazabicyclic, azabicyclic or diazabicyclic ring which has 7 to 10 ring members, which rings optionally are substituted in one or more positions, or a group —[C(R4)(R5)]xN(R2a)(R3a)];
R2a, R3a, R4, R5, R6 and x are as defined in the claims, and n is 0 or 1; and pharmaceutically acceptable salts, hydrates and prodrug forms thereof.
The compounds may be prepared by per se conventional methods and can be used for treating a human or animal subject suffering from a serotonin-related disorder, such as eating disorders, especially obesity, memory disorders, schizophrenia, mood disorders, anxiety disorders, pain, sexual dysfunctions, and urinary disorders. The invention also relates to such use as well as to pharmaceutical compositions comprising a compound of formula (I).
本发明涉及公式(I)的化合物:其中Ar是可选取代的芳基或杂芳基;A是(i)-O-,-S-,-SO2-,-NH-,(ii)C1-4烷基或C1-6酰基取代的氮原子或(iii)C1-8烷基链或具有2至8个链原子的杂烷基链,可选地含有至少一个不饱和度,并且可以取代和/或包含桥以形成具有3-8个环成员的饱和或部分或完全不饱和的环;B是-C(R4)(R5)-,-OC(R4)(R5)-,-N(R6)C(R4)(R5)-,-N(R6)-,-O-,-S-或-SO2-;R是可选的取代C3-8环烷基,芳基或杂芳基;R1是(i)饱和或不饱和的氮杂环或
氨基氮杂环,或饱和的二氮杂环或
氨基二氮杂环,其具有4至7个环成员,或饱和的
氨基
氮杂双环,
氮杂双环或二
氮杂双环,其具有7至10个环成员,这些环可选地在一个或多个位置上取代,或者是一个组-[C(R4)(R5)]xN(R2a)(R3a)];其中,R2a,R3a,R4,R5,R6和x如权利要求书中所定义,n为0或1;以及其药学上可接受的盐,
水合物和前药形式。这些化合物可以通过自身常规方法制备,并可用于治疗患有
血清素相关疾病的人类或动物,例如进食障碍,尤其是肥胖症,记忆障碍,精神分裂症,情绪障碍,焦虑症,疼痛,性功能障碍和泌尿系统疾病。本发明还涉及这种用途以及包含公式(I)化合物的制药组合物。
