The use of novel and improved chemopreventive and chemotherapeutic agents for the prevention and treatment of cancer is on the rise. Natural products have always afforded a rich source of such agents. Epidemiological evidence suggests that a higher flavonoid intake is associated with low cancer risk. Accumulating data clearly indicate that the induction of apoptosis is an important component in the chemoprevention of cancer by naturally occurring dietary agents. Resveratrol, a naturally occurring polyphenol, demonstrates pleiotropic health benefits, including antioxidant, anti-inflammatory, antiaging, cardioprotective, and neuroprotective activities. Because of these properties and their wide distribution throughout the plant kingdom, resveratrol is envisioned as a potential chemopreventive/curative agent. Currently, a number of preclinical findings from our lab and elsewhere suggest resveratrol to be a promising natural weapon in the war against cancer. Remarkable progress in elucidating the molecular mechanisms underlying the anticancer properties of resveratrol has been achieved. Here, we focus on some of the myriad pathways that resveratrol targets to exert its chemopreventive role and advocate that resveratrol holds tremendous potential as an efficient anticancer drug of the future.
新型和改良的化学预防和化疗药物在癌症的预防和治疗中的应用正在增加。天然产物一直是这些药物的丰富来源。流行病学证据表明,黄酮类化合物摄入量较高与癌症风险较低有关。越来越多的数据清楚地表明,诱导细胞凋亡是天然存在的饮食因子通过化学预防癌症的重要组成部分。白藜芦醇是一种天然存在的多酚,具有多种健康益处,包括抗氧化、抗炎、抗衰老、心脏保护和神经保护作用。由于这些特性及其在整个植物界的广泛分布,白藜芦醇被视为一种有潜力的化学预防/治疗药物。目前,我们实验室和其他实验室的一些临床前发现表明,白藜芦醇是对抗癌症的一种有前途的天然武器。在阐明白藜芦醇抗癌特性的分子机制方面已经取得了显著的进展。在这里,我们专注于白藜芦醇针对的众多途径中的一些,以发挥其化学预防作用,并主张白藜芦醇作为未来高效抗癌药物具有巨大潜力。
