Phytochemicals derived from natural plants have been used commonly for the prevention and/or treatment of different diseases due to the belief of their safety. Many plant species synthesize toxic chemicals. New natural chemicals are being discovered but their toxic effects are unknown. Phytochemicals have been regarded as possible antioxidants. But on the other hand it is suggested that various phenolic antioxidants can display pro-oxidant properties at high doses. In this review, the role of some phytochemicals (epigallocathecin gallate, carvacrol, galangin, limonene, lycopene, naringin, puerarin, terpinene, thymol and ursolic acid) on the prevention of DNA damage will be discussed...

Glucocorticoid receptors (GRs) exert actions on the hippocampus that are important for memory formation. There are correlations between vascular dysfunctions and GR-related gene expression. Both vascular dysfunction and GR gene expression decline occur during the ageing process. Therefore, hypotensors, which have effects on improving vascular dysfunction, may be able to ameliorate GR gene expression decline in ageing mice and improve ageing-mediated memory deficits. In this study, we hypothesized that hypotensors could alleviate the decline of GR gene expression and ameliorate age-induced learning and memory deficits in a D-gal-induced ageing mice model...

Amyloid β (Aβ) is a critical stimulator that promotes the progression of age-related macular degeneration (AMD). NLRP3 inflammasome activation induced by Aβ is estimated to be responsible for retinal pigment epithelium (RPE) dysfunction in such disease. Puerarin, one of the major active constituents of Kudzu root, has been widely used in the clinical treatment of AMD in China for decades; however, the detailed molecular mechanism remains far from clear. In this study, we investigated the protective effect and underlying mechanism of puerarin against Aβ1-40-induced NLRP3 inflammasome activation in LPS-primed ARPE-19 cells...

It was reported that puerarin decreases the total cholesterol, low-density lipoprotein cholesterol (LDL-C), triglyceride (TG) and increases high-density lipoprotein cholesterol (HDL-C) level, but the underlying mechanism is unclear. This study was designed to determine whether puerarin decreased lipid accumulation via up-regulation of ABCA1-mediated cholesterol efflux in THP-1 macrophage-derived foam cells. Our results showed that puerarin significantly promoted the expression of ATP-binding cassette transporter A1 (ABCA1) mRNA and protein via the AMP-activated protein kinase (AMPK)-peroxisome proliferator-activated receptor gamma (PPARγ)-liver X receptor-alpha (LXR-α) pathway and decreased cellular lipid accumulation in human THP-1 macrophage-derived foam cells...

Puerarin (Pur), which is the major bioactive ingredient extracted from the root of Pueraria lobata (Willd.) Ohwi, has been demonstrated to relieve myocardial ischemia/reperfusion (I/R) injury. Macroautophagy, or autophagy, is an evolutionarily conserved cellular catabolic mechanism that is involved in myocardial I/R injury. The present study evaluated the involvement of autophagy in the protective mechanisms of Pur during myocardial hypoxia/reoxygenation (H/R). The results revealed that Pur and 3‑methyladenine pretreatment exerted a cardioprotective effect against H/R‑induced cell viability loss...
