Natural Products Acting as Senolytics and Senomorphics Alleviate Cardiovascular Diseases by Targeting Senescent Cells

Taken together, cardiovascular diseases (CVDs) have become one of the prime causes of the global disease burden. Aging is closely related to CVDs and is considered to be one of the crucial factors in the incidence of CVDs. In the process of aging, cellular senescence(definition) is an important cause of CVDs such as atherosclerosis and atrial fibrillation. The treatment for CVDs by targeting senescent cells has been carried out in cellular models, animal experiments, and anti-aging clinical trials. Chemical approaches to regulate the fate of senescent cells by senolytics(definition) and senomorphics, which could selectively eliminate senescent cells or inhibit their senescence-associated secretory phenotype (SASP) secretion, have been increasingly explored. Importantly, many natural products with promising biological activity extracted from food or medicine–food homology have the above-mentioned effects. Furthermore, the identification of the target cells or target proteins of these natural products is of great significance for the indication of their mechanism of action, and it also lays a scientific foundation for the realization of precision nutrition intervention in the future. This review details how senescent cells affect CVDs, how natural products target senescent cells through nutritional intervention, and research methods for natural products in cardiovascular aging.
