A tetradentate chelating monoquinoline derivative with a structure as shown in formula (I) is able to specifically chelate redox active metal ions like copper ions that are dis-regulated in neurodegenerative diseases (Alzheimer's disease, Huntington's disease, Parkinson's disease, and amyotrophic lateral sclerosis), or copper accumulation disease like Wilson's disease. The binding constants of these derivatives for zinc are 6-10 orders of magnitude below that ones for copper, and these derivatives have a good capability of reducing an oxidative stress. The method for preparing the derivative is simple and the derivatives have good application prospects in manufacturing drugs for neurodegenerative diseases and diseases related to disorder of copper metabolism.
