JG-98 is primarily used in research settings to study its effects on cancer cells. It functions as an inhibitor of the heat shock protein 70 (HSP70), which plays a critical role in protein folding and stress response in cells. By targeting HSP70, JG-98 disrupts the survival mechanisms of cancer cells, making it a potential candidate for cancer therapy. Researchers are exploring its ability to enhance the effectiveness of other anticancer treatments by weakening cancer cells' resistance to apoptosis. Additionally, JG-98 is being investigated for its potential in treating neurodegenerative diseases, as HSP70 is also involved in protein misfolding disorders like Alzheimer's and Parkinson's. Its application remains largely experimental, with ongoing studies to determine its safety and efficacy in clinical settings.
