Provided are 7-hydroxy-6-methoxy-1,2,3,4-tetrahydroisoquinoline derivatives and synthesis methods thereof. The compounds significantly inhibit the production of nitrogen monoxide (NO) and superoxide in an activated microglial cell and expressions of TNF-α, IL-1β inducive NO synthase and cyclooxygenase-2 genes. They also prevent NF-kB shift to a nucleus, decrease reactive oxygen species (ROS), inhibit expression of GTP cyclohydrolase I gene and over-production of tetrahydrobiopterin (BH

), and protect dopaminergic neurons from injury due to activated microglial cells. Consequently, the compounds are effective in treating inflammatory and neurodegenerative diseases.
提供了7-羟基-6-甲氧基-1,2,3,4-四氢异喹啉衍生物及其合成方法。这些化合物显著抑制活化小胶质细胞中一氧化氮(NO)和超氧化物的产生,以及TNF-α、IL-1β诱导NO合成酶和环氧合酶-2基因的表达。它们还可以防止NF-kB转移到细胞核,降低活性氧自由基(ROS)的水平,抑制GTP环水合酶I基因的表达和四氢生物蝶呤(BH4)的过度产生,并保护多巴胺能神经元免受活化小胶质细胞引起的损伤。因此,这些化合物对于治疗炎症和神经退行性疾病具有有效性。
