Descriptions:
Luteolin, is a common flavonoid that exists in many types of plants including fruits, vegetables, and medicinal herbs, has anti-oxidant, anti-inflammation, anti-allergy and anticancer, has been used in Chinese traditional medicine for treating various diseases such as hypertension, inflammatory disorders, and cancer. [1]
Luteolin can reduce production of proinflammatory mediators and inhibit LPS-induced IL-6 production in the brain by inhibiting the JNK signaling pathway and activation of AP-1 in microglia, also shows potent anti-inflammatory activities by inhibiting nuclear factor kappa B (NFkB) signaling in immune cells, thus, could be a promising candidate to develop immuno-modulatory and neuroprotective therapies for the treatment of neurodegenerative disorders.[2-3]
Luteolin induces apoptosis in various cancer cells, one mechanism through death receptor 5 (DR5) upregulation, treatment with luteolin might be promising as a new therapy against cancer. [4]
Luteolin attenuates TGF-β1-induced epithelial–mesenchymal transition of lung cancer cells by interfering in the PI3K/Akt–NF-κB–Snail pathway, strengthen the anti-cancer effects of flavonoid compounds via the regulation of migration/invasion and EMT ability of various cancer cells.[5]
