[Asia Economy Reporter Junho Hwang] Domestic researchers have developed a technology that can simultaneously suppress multiple causes of Alzheimer's disease. This technology controls the causes of the disease through the redox reactions of low molecular weight compounds. Attention is focused on whether this will open a new chapter in the development of Alzheimer's treatments. The Korea Advanced Institute of Science and Technology (KAIST) introduced the joint research results of Professor Mihee Lim's chemistry team on the 11th.

Professor Lim's research team, together with Professor Muhyun Baek from the same school and Professor Jooyoung Lee from Seoul Asan Medical Center, confirmed that the causative factors of Alzheimer's disease can be easily controlled using the redox reactions of simple low molecular weight compounds.

They experimentally demonstrated not only the potential antioxidant effect against reactive oxygen species through the redox reactions of low molecular weight compounds but also a significant reduction in the aggregation and fibril formation of amyloid beta or metal-amyloid beta. Reactive oxygen species, amyloid beta, and metal ions are known as major causative factors of Alzheimer's disease.

The research team also validated their findings through experiments on animal models (laboratory mice) with Alzheimer's disease. By injecting representative low molecular weight compounds with good in vitro reactivity and properties suitable for bioapplications into the mice, they obtained results showing a significant reduction in the amount of amyloid beta accumulated in the brain and improvement in impaired cognitive abilities and memory in the Alzheimer's animal model.

Professor Mihee Lim stated, "This study is meaningful in proving that the difference in the oxidation degree of very simple aromatic low molecular weight compounds can clearly distinguish the presence or absence of reactivity with various causative factors," adding, "If this method is used as a design approach for new drug development, it will greatly reduce costs and time while achieving maximum effectiveness."

She further emphasized, "The proposed design method for therapeutics is expected to increase the success rate of developing treatments for various degenerative brain diseases."
