Abstract: The aging population is steadily increasing, with aging and age-related diseases serving as major risk factors for morbidity, mortality, and economic burden. Peanuts, known as the “longevity nut” in China, have been shown to offer various health benefits, with peanut skin extract (PSE) emerging as a key compound of interest. This study investigates the bioactive compound in PSE with anti-aging potential and explores its underlying mechanisms of action. Procyanidin A1 (PC A1) was isolated from PSE, guided by the K6001 yeast replicative lifespan model. PC A1 prolonged the replicative lifespan of yeast and the yeast-like chronological lifespan of PC12 cells. To further confirm its anti-aging effect, cellular senescence, a hallmark of aging, was assessed. In senescent cells induced by etoposide (Etop), PC A1 alleviated senescence by reducing ROS levels, decreasing the percentage of senescent cells, and restoring proliferative capacity. Transcriptomics analysis revealed that PC A1 induced apoptosis, reduced senescence-associated secretory phenotype (SASP) factors, and modulated the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway. The antioxidative capacity of PC A1 was also evaluated, showing enhanced resistance to oxidative stress in PC12 cells by reducing reactive oxygen species (ROS) and malondialdehyde (MDA) levels and increasing superoxide dismutase (SOD) activity. Moreover, PC A1 induced autophagy, as evidenced by an increase in fluorescence-labeled autophagic compartments and confirmation via Western blot analysis of autophagy-related proteins. In addition, the treatment of an autophagy inhibitor abolished the antioxidative stress and senescence-alleviating effects of PC A1. These findings reveal that PC A1 extended lifespans and alleviated cellular senescence by enhancing oxidative stress resistance and inducing autophagy, positioning it as a promising candidate for further exploration as a geroprotective agent.

Abstract: Currently, nutraceuticals and functional food/cosmeceutical sectors are seeking natural molecules to develop various types of phytopharmaceutical products. Flavonoids have been reported in antioxidant and many medical/pharmacological activities. Monochoria angustifolia or Siam violet pearl medicinal plant is the newest species of the genus Monochoria C. Presl, which have long been consumed as food and herbal medicines. Though previous work showed that apigenin-7-O-glucoside is the most abundant antioxidant phytochemical found in this medicinal plant, the report on anti-aging activity is still lacking and needs to be filled in. The objective of this work is to explore anti-aging capacities of the most abundant antioxidant phytochemical reported in this plant using both in silico and in vitro assessments. In addition, pharmacokinetic properties were predicted. Interestingly, the results from both in silico and in vitro analysis showed a similar trend that apigenin-7- O-glucoside is a potential anti-aging agent against three enzymes. The pharmacokinetic properties, such as adsorption, distribution, metabolism, excretion and toxicity (ADMET), of this compound are also provided in this work. The current study is also the first report on anti-aging properties of this Thai medicinal plant. However, the safety and efficacy of future developed products from this compound and clinical study should be determined in the future.

创伤愈合是指机体遭受外力作用，皮肤等组织出现离断或缺损后的愈复过程，包括各种组织的再生和肉芽组织增生、瘢痕组织形成的复杂组合，表现出各种过程的协同作用。伤口创伤愈合的基本过程:急性炎症期→细胞增生期→瘢痕形成期→表皮及其它组织再生。根据损伤程度及有无感染，创伤愈合可分为一期愈合、二期愈合、三期愈合3种类型。
