The present invention refers to pyridazin-3(2H)-one derivatives of general structure I, II and III, which are selective MAO-B inhibitors, and to the use thereof for preparing medicaments intended to treat disorders derived from MAO-B hyperactivity, particularly degenerative disorders of the central nervous system (CNS), such as Parkinson's disease (PD), Alzheimer's disease (AD) and other dementias. These are pyridazin-3(2H)-one derivatives having dithiocarbamate moieties bonded to position 4, 5 or 6 through an alkyl chain of variable length (n=1, 2, 3). This invention is also directed to the preparation of said compounds.
本发明涉及一般结构 I、II 和 III 的哒嗪-3(2H)-酮衍生物,它们是选择性 MAO-B 抑制剂,并涉及使用它们制备药物,以治疗 MAO-B 活性亢进引起的疾病,特别是中枢神经系统(CNS)的退行性疾病,如帕金森病(PD)、阿尔茨海默病(AD)和其他痴呆症。这些衍生物为哒嗪-3(2H)-酮衍生物,其第 4、5 或 6 位通过长度可变的烷基链(n=1、2、3)键合有二硫代氨基甲酸酯分子。本发明还涉及上述化合物的制备。
