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.
