Tanshinol B is widely studied for its potential therapeutic applications, particularly in cardiovascular and cerebrovascular diseases. It exhibits strong antioxidant properties, helping to reduce oxidative stress in vascular tissues, which plays a key role in preventing atherosclerosis and ischemia-reperfusion injury. The compound has shown neuroprotective effects in models of stroke, where it helps reduce brain infarct size and improve neurological outcomes. It also demonstrates anti-inflammatory activity by inhibiting pro-inflammatory cytokines and signaling pathways such as NF-κB. Due to these properties, Tanshinol B is being explored as a candidate for treating conditions like myocardial infarction, cerebral ischemia, and chronic inflammatory disorders. Additionally, it may support liver protection and has been investigated for its potential in managing diabetic complications.
