Korean Scientists Make Groundbreaking Discovery in Lifespan Extension with IU1 Drug

Korean researchers have made significant strides in anti-aging science by investigating a drug called IU1, aimed at enhancing protein quality control systems. Aging is linked to various health issues, primarily due to the decline of proteostasis—the body’s ability to maintain protein balance. As we age, the effectiveness of our protein quality control systems diminishes, leading to degenerative diseases.

Led by Professor Seogang Hyun from Chung-Ang University, the team explored how IU1 could improve the function of proteasomes and autophagy, two critical systems for maintaining proteostasis. Using fruit flies, they found that IU1 inhibits ubiquitin specific peptidase 14, thereby enhancing both proteasomal and autophagic activity, which significantly improved age-related muscle weakness and extended lifespan.

These findings hold promise for developing therapies for age-related diseases like Alzheimer’s and Parkinson’s. The research, published in the journal Autophagy, could pave the way for new treatments that enhance quality of life and longevity.
