热量限制(CR)在延长寿命和延缓年龄相关疾病的发生方面具有多种作用,并且被认为是唯一确定的实验性抗衰老干预措施。已经确定了几种可以复制CR有益效果的药理学药物,称为卡路里限制模拟物(CRM)。包括涉及sirtuins(特别是SIRT1)和哺乳动物雷帕霉素靶蛋白(mTOR)的营养感应途径可能调节CR的生理学,并且已经使用动物模型鉴定和研究了调节这些特定途径的候选CRM。在本章中,我们重点介绍候选CRM,包括sirtuin激活化合物(STAC)和mTOR抑制剂,它们延缓衰老,以及评估寿命和代谢紊乱的方法。
Calorie restriction (CR) has a variety of effects on extending lifespan and delaying the onset of age-related diseases, and it is accepted as the only established experimental antiaging intervention. Several pharmacological agents that can replicate the beneficial effects of CR, called calorie restriction mimetics (CRMs), have been identified. The nutrient-sensing pathways including those involving sirtuins (especially SIRT1) and mammalian target of rapamycin (mTOR) may regulate the physiology of CR, and candidate CRMs that modulate these specific pathways have been identified and investigated using animal models. In this chapter, we focus on candidate CRMs including sirtuin-activating compounds (STACs) and mTOR inhibitors, their slowing of aging, and methods for evaluation of lifespan and metabolic disorders.
