What is Fisetin
Fisetin is a natural flavonoid compound primarily extracted from the Smoke Tree (Cotinus coggygria). It is also found in various fruits and vegetables, including strawberries, apples, onions, and cucumbers.
Fisetin exhibits a wide range of pharmacological activities, such as anti-inflammatory, antioxidant, anti-cancer, anti-thrombosis, neuroprotective, memory-enhancing, and therapeutic effects on diabetic kidney damage.
Recent studies have highlighted its anti-tumor potential, demonstrating its ability to inhibit tumor cell proliferation and induce apoptosis. This has made Fisetin increasingly popular in the pharmaceutical intermediates market.
