Inhibition of lactate dehydrogenase (LDH) represents an innovative approach to tackle cancer because this peculiar glycolytic metabolism is characteristic of most invasive tumor cells. An investigation into the biological properties of saffron extracts led to the discover of their LDH-inhibition properties. In particular, the most important saffron components, crocetin, was found to inhibit LDH (IC50
乳酸脱氢酶(LDH)的抑制代表了一种解决癌症的创新方法,因为这种独特的糖酵解代谢是大多数侵袭性肿瘤细胞的特征。对藏红花提取物生物学特性的研究导致发现了它们对LDH的抑制特性。特别是,发现最重要的藏红花成分藏红花素抑制LDH(IC 50 = 54.9±4.7μM)。该类胡萝卜素是通过化学合成独立产生的,其LDH抑制特性通过其对两种糖酵解癌细胞系(A549和HeLa,IC 50分别为114.0±8.0和113.0±11.1μM)。本文描述的结果表明,藏红花可能是预防癌症的有益饮食成分,可能有助于批准的癌症疗法的功效。
