Description: <p>ISL is a distinct natural chalcone, chemically identified as 2′,4′,4-trihydroxychalcone, found particularly in licorice species such as Glycyrrhiza spp.ISL has substantial preclinical evidence involving anticancer, anti-inflammatory, antioxidant, metabolic, and neuroprotective effects. Reported anticancer actions include inhibition of proliferation, angiogenesis, EMT, invasion, and metastasis, with induction of apoptosis, cell-cycle arrest, autophagy, or ferroptosis depending on the model. Frequently reported pathways include PI3K/AKT/mTOR, NF-κB, STAT3, MAPK, Wnt/β-catenin, Nrf2, and Src signalling.</p>
