    • The present invention provides new benzofuranyl-tetrahydropyridines and -piperidines of the general formula I ##STR1## in which R.sub.1 and R.sub.2 independently of one another are hydrogen or lower alkyl or together are lower alkylene, R.sub.3 is hydrogen, lower alkyl, lower alkenyl, lower alkynyl, cyclo-lower alkyl or cyclo-lower alkyl-lower alkyl and Y.sub.1 and Y.sub.2 are each hydrogen or together are an additional bond, and the ring A is not further substituted or is further substituted by lower alkyl, lower alkoxy, halogen with an atomic number not more than 35, cyano or hydroxyl and the pharmaceutically acceptable acid addition salts thereof, and antidepressant preparations containing these compounds. The compounds according to the invention have valuable pharmacological properties. In particular, they inhibit the absorption of serotonin by mesencephalic synaptosomes, the serotonin depletion induced in the brain of rats by H 75/12, the absorption of noradrenalin by mesencephalic synaptosomes in rats and the noradrenalin depletion induced in the brain of rats by H 77/77. In the same dosage they also effect inhibition of monoamino-oxidase in the brain of rats and in the liver of rats. Furthermore, they intensify the "head twitch" induced by 5-hydroxy-tryptophan, and are distinguished by good tolerance. The compounds of the general formula I and their pharmaceutically acceptable acid addition salts can therefore be used as psychopharmaceuticals and in particular as antidepressants.
    • 本发明提供了通式Ⅰ(I)的新的苯并呋喃基 - 四氢吡啶和哌啶,其中R 1和R 2彼此独立地是氢或低级烷基或一起是低级亚烷基,R 3是氢,低级烷基,低级 烯基,低级炔基,环低级烷基或环低级烷基 - 低级烷基,Y 1和Y 2各自为氢或一起为附加键,并且环A不被进一步取代或进一步被低级烷基,低级烷氧基, 原子数不超过35的卤素,氰基或羟基及其药学上可接受的酸加成盐,以及含有这些化合物的抗抑郁制剂。 根据本发明的化合物具有有价值的药理学性质。 特别是,它们通过中脑突触体抑制5-羟色胺的吸收,H75 / 12的大鼠脑内诱导的血清素消耗,大鼠中脑突触体的去甲肾上腺素的吸收以及大鼠脑内诱发的去甲肾上腺素的耗竭 / 77。 在相同的剂量下,它们也影响大鼠脑和大鼠肝脏中单氨氧氧化酶的抑制。 此外,它们加剧了由5-羟基色氨酸引起的“头部抽搐”,并且具有良好的耐受性。 因此,通式I的化合物及其药学上可接受的酸加成盐可以用作心理药物,特别是抗抑郁药。
