The present invention relates to novel oxadiazole derivatives having pharmacological activity, processes for their preparation, compositions containing them and their use in the treatment of neurological, psychiatric disorders and gastrointestinal disorders. wherein R1 and R2 independently represent hydrogen, C1-6 alkyl or C3-6 cycloalkyl; or R1 and R2 together with the nitrogen atom to which they are attached form a nitroge containing heterocyclyl group which is unsubstituted or substituted with 1, 2, or 3 substituents selected from methyl or fluoro; Q represents -(CH2)n- wherein n represents 3 or 4; A represents a phenyl ring and B represents a 5 or 6 membered heteroaryl ring or B represents a phenyl ring and A represents a 5 or 6 membered heteroaryl ring; R3 and R4 independently represent C1-6 alkyl, C1-6 alkoxy and halo; t and m independently represent an integer from 0 to 3. Compounds of formula (I) and their pharmaceutically acceptable salts may have affinity for and be agonists at the nicotinic α7 receptor and are believed to be of potential use in the treatment of neurological diseases including Alzheimer's disease.
本发明涉及具有药理活性的新型噁二唑衍生物,其制备方法,含有它们的组合物以及它们在治疗神经系统、精神疾病和胃肠疾病中的用途。其中,R1和R2独立地代表氢、C1-6烷基或C3-6环烷基;或者R1和R2与它们连接的氮原子一起形成一个含氮杂环基团,该基团未取代或取代有1、2或3个甲基或氟代基;Q代表-(CH2)n-,其中n代表3或4;A代表苯环,B代表5或6成员的杂芳环,或者B代表苯环,A代表5或6成员的杂芳环;R3和R4独立地代表C1-6烷基、C1-6烷氧基和卤素;t和m独立地代表0到3的整数。式(I)化合物及其药学上可接受的盐可能具有亲和力,并且可能是烟碱性α7受体的激动剂,据信可能在治疗包括阿尔茨海默病在内的神经系统疾病中有潜在用途。
