In order to discover lifespan-extending compounds made from natural resources, activity-guided fractionation of Roscoe (Zingiberaceae) ethanol extract was performed using the () model system. The compound 6-gingerol was isolated from the most active ethyl acetate soluble fraction, and showed potent longevity-promoting activity. It also elevated the survival rate of worms against stressful environment including thermal, osmotic, and oxidative conditions. Additionally, 6-gingerol elevated the antioxidant enzyme activities of , and showed a dose-depend reduction of intracellular reactive oxygen species (ROS) accumulation in worms. Further studies demonstrated that the increased stress tolerance of 6-gingerol-mediated worms could result from the promotion of stress resistance proteins such as heat shock protein (HSP-16.2) and superoxide dismutase (SOD-3). The lipofuscin levels in 6-gingerol treated intestinal worms were decreased in comparison to the control group. No significant 6-gingerol-related changes, including growth, food intake, reproduction, and movement were noted. These results suggest that 6-gingerol exerted longevity-promoting activities independently of these factors and could extend the human lifespan.
为了发现由自然资源制成的寿命延长化合物,使用()模型系统对山姜属(姜科)乙醇提取物进行了活性导向分级分离。从活性最强的乙酸乙酯可溶级分中分离出化合物6-姜酚,其显示出强大的促长寿活性。它还提高了蠕虫在包括热、渗透和氧化条件在内的应激环境下的存活率。此外,6-姜酚提高了()的抗氧化酶活性,并显示出蠕虫细胞内活性氧(ROS)积累的剂量依赖性降低。进一步的研究表明,6-姜酚介导的蠕虫应激耐受性增加可能是由于促进了应激抗性蛋白,如热休克蛋白(HSP-16.2)和超氧化物歧化酶(SOD-3)。与对照组相比,6-姜酚处理的肠道蠕虫中的脂褐素水平降低。未观察到与6-姜酚相关的显著变化,包括生长、食物摄入、繁殖和运动。这些结果表明,6-姜酚独立于这些因素发挥促长寿活性,并可能延长人类寿命。
