Recent research has unveiled promising insights into the neuroprotective potential of a compound called isoliquiritigenin (ISL), particularly in the context of cerebral ischemia-reperfusion injury (CIRI). This condition, which occurs when blood flow is restored to the brain after a period of ischemia, can lead to significant neuronal damage and is a leading cause of adult disability and mortality. The study, led by Xiaobing Lan from the Key Laboratory of Protection, Development and Utilization of Medicinal Resources in Liupanshan Area at Ningxia Medical University, highlights how ISL can mitigate the harmful effects of CIRI by targeting oxidative stress and mitochondrial dysfunction.
In experiments involving mice, ISL treatment markedly reduced cerebral infarction and neurological deficits typically associated with CIRI. The study’s findings indicate that ISL not only enhances cell viability but also maintains critical enzyme activities that are often compromised during oxygen-glucose deprivation. “Our research shows that ISL can significantly improve redox homeostasis and restore mitochondrial function, which are crucial for neuronal survival,” said Lan. This discovery could have far-reaching implications, particularly in developing therapies for conditions where brain function is compromised.
The mechanistic analysis revealed that ISL activates the Nrf2 pathway, a crucial regulator of the body’s antioxidant response. By facilitating the dissociation of Keap1/Nrf2, ISL promotes the nuclear transfer of Nrf2, enhancing its ability to combat oxidative stress. “The activation of the Nrf2 pathway is critical for protecting against neuronal apoptosis and mitochondrial dysfunction,” Lan added. This dual action of ISL not only shields neurons but also supports mitochondrial health, which is vital for energy production in brain cells.
The implications of this research extend beyond neuroprotection. As the energy sector increasingly recognizes the importance of mitochondrial function in cellular health, compounds like ISL could inspire novel approaches to enhance energy metabolism in various tissues. The potential commercialization of ISL as a therapeutic agent could lead to new treatments for neurodegenerative diseases and other conditions associated with mitochondrial dysfunction, thereby creating a market for neuroprotective drugs.
The study was published in ‘Redox Biology’, which translates to ‘Biologia Redox’ in English, underscoring the significance of oxidative stress in biological systems.

As we advance our understanding of compounds like ISL, the intersection of neuroscience and energy metabolism could pave the way for innovative therapies that not only protect the brain but also enhance overall cellular energy efficiency.
