Polysaccharide from Polygonatum sibiricum (PSP) possesses antioxidant, antiaging, and neuroprotective activities. However, whether how the steaming process influences biological activities of PSP, especially against aging-related memory impairment, is not yet known. In this study, rhizome was subjected to a "nine nine drying" process, then PSPs with different times were abstracted. Thereafter, physicochemical properties qualified; antioxidant evaluated in D-gal-induced HT-22 cell model, effects (PSP0, PSP5 PSP9) on using D-gal-injured mice. Our results showed that while steamed had low pH value large negative charge, they shared similar main chains substituents. Cellular experiments activity increased. PSP0, PSP5, PSP9 could significantly ameliorate impairment mice, showing optimal effect. Meanwhile, demonstrated best effect terms preventing death synaptic injury Additionally, increased anti-oxidative stress-related protein expression decreased inflammation-related Collectively, improves likely by increasing PSPs.

Mushroom bioactive peptides (MBPs) are extracted directly or indirectly from edible mushrooms. MBPs known to have antioxidant, anti-aging, antibacterial, anti-inflammatory and anti-hypertensive properties, facilitate memory cognitive improvement, antitumour anti-diabetes activities, cholesterol reduction. exert antioxidant effects by regulating the MAPK, Keap1-Nrf2-ARE, NF-κB TNF pathways. In addition, anti-tumour stimulating proliferation of macrophages. The bioactivities closely related their molecular weights, charge, amino acid compositions sequences. Compared with animal-derived peptides, ideal raw materials for healthy functional products advantages abundance resources, safety, low price, easy-to-achieve large-scale production valuable nutrients health maintenance disease prevention. this review, preparation, bioactivities, mechanisms structure–activity relationships were described. main challenges prospects application in also discussed. This review aimed provide a comprehensive perspective MBPs.

For centuries, humans have used mushrooms as both food and pro-health supplements. Mushrooms, especially those related to the functions of human immune system, are rich in dietary fiber, minerals, essential amino acids, various bioactive compounds significant health-promoting properties. Immunoregulatory include lectins, terpenes, terpenoids, polysaccharides, fungal immunomodulatory proteins (FIPs). The distribution these varies from one species mushroom another, their activities depend on core structures chemical modifications composition fractions. In this review, we describe active medical mushrooms. We summarize potential mechanisms for vitro vivo detail approaches developing applying Finally, discuss applications peptides highlight areas that require improvement before widespread use therapeutic agents explore status clinical studies products, well prospect application AMPs ‘drug-like’ with great treatment non-healing chronic wounds multiresistant infections.

Abstract Background Natural products are an important source of drugs or lead compounds for the treatment senescence. The buds Wikstroemia chamaedaphne Meisn a traditional Chinese medicine to cure edema, schizophrenia and epilepsy. A flavonoid extract W. (FEW) was prepared from methanolic by our group previously, which including eight flavonoids with content (55.19 ± 0.32) %. In this study, anti-senescence effects related mechanisms FEW on D-galactose-induced PC12 cells were investigated first time. Results High doses D-galactose could induce cell senescence, whereas delay senescence decreasing SA-β-gal positivity, increasing SOD activity, reducing MDA levels, improving morphology, inhibiting cycle arrest down-regulating expression senescence-related proteins P16, P21 P53. Subsequently, potential underlying elucidated through integration network pharmacology transcriptomics. main signaling pathways involved found be cancer pathway, FOXO PI3k–Akt AGE–RAGE protein digestion uptake, etc. may pathway as revealed western blot experiments. Conclusion Our study that has effects. This suggest acts agent age-related neurological diseases.
