TWS119 is primarily used in research settings to study its effects on cellular processes, particularly in the field of cancer biology. It acts as an inhibitor of glycogen synthase kinase-3 beta (GSK-3β), which plays a role in various signaling pathways. Researchers utilize TWS119 to investigate its potential in inducing differentiation in stem cells, especially in neural stem cells, to better understand cell development and regeneration. Additionally, it is explored for its therapeutic potential in diseases like Alzheimer's, where GSK-3β inhibition may help in reducing neurofibrillary tangles. Its application in cancer research focuses on its ability to modulate pathways involved in tumor growth and apoptosis, offering insights into novel treatment strategies.
