The invention provides compounds of the formula:
wherein R1, R2 and R3, which can be the same or different, are each selected from hydrogen, chloro, bromo, fluoro, methyl, ethyl, methoxy, amino, hydroxy and nitro; R4 is hydrogen or alkyl of 1 to 7 carbon atoms; -X- is
wherein R5 is hydrogen, hydroxy or-OR6, and R6 is alkyl of 1 to 7 carbon atoms or aryl of 6 to 10 carbon atoms; and their non-toxic pharmaceutically acceptable acid addition salts and mixtures thereof. Processes for the preparation and use of the subject compounds are described, as are novel pharmaceutical compositions comprising at least one of the subject compounds or their salts. The compounds and their non-toxic salts exhibit valuable pharmacological activity and are useful in the treatment of mammals, particularly as anti-hypertensive or anti-ulcer agents. Furthermore, they are useful as diuretic, sedative, analgesic, anti-inflammatory and tranquilizing agents.
本发明提供了如下式的化合物:
其中R1、R2和R3可以相同或不同,它们各自选自氢、氯、溴、氟、甲基、乙基、甲氧基、氨基、羟基和硝基;R4是氢或1至7个碳原子的烷基;-X-是
其中 R5 是氢、羟基或-OR6,R6 是 1 至 7 个碳原子的烷基或 6 至 10 个碳原子的芳基;以及它们的无毒药学上可接受的酸加成盐及其混合物。描述了制备和使用上述化合物的工艺,以及包含至少一种上述化合物或其盐的新型药物组合物。这些化合物及其无毒盐具有宝贵的药理活性,可用于治疗哺乳动物,特别是作为抗高血压或抗溃疡药物。此外,它们还可用作利尿剂、镇静剂、镇痛剂、消炎剂和镇定剂。
