All cells composing of our body undergo their destiny such as proliferation, differentiation, necrosis, apoptosis and senescence depending on their circumstance with time. The errors occurring in these processes develop several aberrations in phenotypes including cancer, inflammation, aging and diseases. New strategy and approach are required to screen anti-aging compounds derived from natural products. Therefore, here we explain the target proteins to play a key role in aging mechanism. In the first place, matrix metalloproteinases (MMPs) are involved in metastasis, chronic inflammation and skin aging as an aging marker. In particular, histone deacetylases (HDACs) give a great attention to aging researchers who try to extend the life span of animal model. In addition, we describe the signaling pathway related to senescence which p53, IGF-1 and SIRT1 play an important role in. Furthermore, autophagy is involved in the signaling pathway associated with aging. Several new compounds modulating the signaling pathway of senescence are introduced in this review. Here, we try to provide a new insight in the molecular basis for the aging mechanism and development of aging marker. In addition, the compounds introduced here could be available for pharmaceutical applications for the prevention and the treatment of diseases related to aging.
