A component having the following formula I: ##STR1## wherein X represents an integer ranging from 1 to 2 or 7 to 13; Y represents an integer ranging from 0 to 5; Z represents an integer ranging from 0 to 5; R.sub.1, R.sub.2 and R.sub.3 are the same or different and represent H or a straight chain or branched lower alkyl; and R' and R" are the same or different and represent H or halogen, and pharmaceutically acceptable salts thereof. Preferably, the lower alkyl has between 1 and 4 carbon atoms and the halogen is selected from the group consisting of fluorine, chlorine, bromine and iodine. The compound is useful as a MAO-B inhibitor. Also within the scope of the present invention is a composition for the inhibition of MAO-B activity and a method for alleviating Parkinsonism, Alzheimer's disease, depression, attention deficit hyperactive disorders, aging and other neuropsychiatric disorders and for improving the quality of life. They comprise the use of a compound of Formula I wherein x is an integer ranging from 1 to 13.
以下是具有以下公式I的组分:##STR1## 其中X表示从1到2或7到13的整数; Y表示从0到5的整数; Z表示从0到5的整数; R.sub.1,R.sub.2和R.sub.3相同或不同,分别表示H或直链或支链低烷基; R'和R"相同或不同,分别表示H或卤素,以及其药学上可接受的盐。最好,低烷基具有1到4个碳原子,卤素选自氟、氯、溴和碘。该化合物可用作MAO-B抑制剂。此外,本发明范围还包括一种用于抑制MAO-B活性的组合物,以及缓解帕金森病、阿尔茨海默病、抑郁症、注意力缺陷多动障碍、衰老和其他神经精神障碍并改善生活质量的方法。它们包括使用公式I的化合物,其中x是从1到13的整数。
