姜黄素又称姜黄色素、酸性黄,是从姜科植物姜黄、莪术、芥末、咖哩、郁金等根茎中提取的一种天然的酚类抗氧化剂,主链为不饱和脂族及芳香族基团,是植物界很稀少的具有二酮的色素,属二酮类化合物,是常用的调料及食用色素,无毒,具有利胆、抗感染、使子宮产生阵发性收缩、降低血胆固醇、抗病毒、抗菌、抗氧化(作用强于α-生育酚)、抗凝血、降血脂和抗动脉粥样硬化等多种药理作用。1985年印度学者Kuttan首次提出姜黄素的抗癌作用,近年来,姜黄素对多种肿瘤细胞的产生、增殖、转移均有抑制作用机理被发现。美国国立肿瘤研究所将其列为第3代肿瘤治疗药。与丝裂霉素C配伍后,降低了丝裂霉素C的用药剂量,同时可以降低单独运用丝裂霉素C产生的肾毒性和骨髓抑制,可提高丝裂霉素C治疗乳腺癌效果。
姜黄素在体内外对各种毒性物质如四氯化碳、黄曲霉素B1、对乙酰氨基酚、环磷酰胺诱导的肝损害均有防护作用,显著降低酒精性肝损害(ALI)动物的碱性磷酸酶、r-谷氨酰转肽酶(r-GT)活性,防止实验性脂肪肝的发生。

A natural phenolic compound. Potent anti-tumor agent having anti-inflammatory and antioxidant properties. Induces apoptosis in cancer cells and inhibits phorbol ester-induced protein kinase C (PKC) ac tivity. Reported to inhibit production of inflammatory cytokines by peripheral blood monocytes and alveolar macrophages. Potent inhibitor of EGFR tyrosine kinase and IB kinase. Inhibits inducible nit ric oxide synthase (iNOS), cycloxygenase and lipoxygenase. Easily penetrates into the cytoplasm of cells, accumulating in membranous structures such as plasma membrane, endoplasmic reticulum and nucle ar envelope. Curcumin is currently being examined as a possible therapeutic for the treatment of Alzheimers disease (Chem. and Eng. News 90(31), 44 (2012)).
