Bioactive peptides (BAP) have received much attention for their antiphotoaging activity in skin because they are natural, safe, and functional. Previous studies have demonstrated that specific amino acids or sequences, as well as some characteristic amino acids, are key to the antiphotoaging effects of BAP. Nevertheless, their inhibitory mechanisms and the association between their structures and abilities are not comprehensively documented. This paper summarizes the mechanisms of antiphotoaging peptides derived from different food processing by-products from the literature over the past 4 years, focusing on the structure–activity relationship based on the inhibitory mechanisms and amino acid compositions of BAP. In addition, the current challenges in obtaining and researching BAP are discussed, and future approaches are proposed. This review provides a theoretical basis for discovering more possible food-borne antiphotoaging peptides and exploring the correlation between the structures and effects of antiphotoaging peptides.</p>\u0000 </div>","PeriodicalId":15802,"journal":{"name":"Journal of Food Biochemistry","volume":"2025 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/jfbc/2836436","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The major honey constituents include sugars and water, while the minor components include organic acids, proteins, short peptides, enzymes, flavonoids, phenolic acids, minerals, vitamins, dicarbonyls, and hydrogen peroxide. It is evident that the constituents of honey affect each other such as the vice versa relation between methylglyoxal and hydrogen peroxide. This study investigated the relations between vitamin C, hydrogen peroxide, and dicarbonyl concentrations in <i>Ziziphus</i> and <i>Acacia</i> honey samples from diverse floral origins and altitudes in Saudi Arabia. Vitamin C and hydrogen peroxide were assessed by redox titrations, and the dicarbonyl molecules were measured using spectrophotometric method. The obtained data were analyzed using SPSS (Version 21.0). The floral origin and the altitude had significant effects on all the studied parameters except vitamin C. Our findings indicated that when the mean concentration of vitamin C in the Ziziphus honey (576 m) (283.84 ± 116.54 mg/100 g) and the mean concentration of the dicarbonyl molecules (176.4 ± 98.06 mg/kg) were high, the hydrogen peroxide mean concentration was low (3.19 ± 0.18 g/kg). When the hydrogen peroxide concentration in the Ziziphus honey (113 m) was high (6.68 ± 0.23 g/kg), the concentration of vitamin C and the dicarbonyl molecules was low (194.48 ± 16.36 mg/100 g and 55.1 ± 38.09 g/kg, respectively). Thus, the present findings suggested that honey samples rich in dicarbonyl molecule concentration are expected to have a high amount of vitamin C and a low concentration of hydrogen peroxide.

Allii Macrostemonis Bulbus (AMB), a traditional Chinese medicinal and edible plant, is believed to be beneficial for mood regulation. Recent preclinical studies have demonstrated its total saponins’ antidepressant effects, though the specific active substances and pathways remain unclear.We first established an <i>in vitro</i> model of hippocampal neuronal injury in mice induced by Glu and conducted preliminary screening of different polarity fractions of AMB’s total saponins, identifying spirostanol-type saponins (AMBN-90) with antidepressant potential. We then analyzed the components and used network pharmacology to predict the targets and pathways of AMBN-90’s antidepressant effects. Next, we established an <i>in vivo</i> mouse model of depression induced by chronic unpredictable mild stress and treated it with AMBN-90 for 6 weeks. Behavioral tests, hippocampal HE staining, and monoamine level measurements in the hippocampus were used to verify AMBN-90’s antidepressant effects. Subsequently, Western blotting and molecular docking methods were employed to preliminarily reveal AMBN-90’s potential antidepressant mechanisms. Results showed that AMBN-90 exhibited significant neuroprotective activity <i>in vitro. In vivo</i>, AMBN-90 significantly improved weight loss and depression-like behaviors in mice exposed to chronic unpredictable mild stress, ameliorated hippocampal neuronal damage, and significantly increased levels of 5-HT, DA, and NE in the hippocampus. It also elevated brain-derived neurotrophic factor levels and reduced neuronal apoptosis by activating the PKA–CREB–BDNF pathway. Molecular docking showed that components of AMBN-90 have superior affinity for the upstream proteins of the pathway, C-type G protein–coupled receptors (GPCRs).

During the whole storage process, texture, total flavonoid contents, and antioxidant activities indicated by DPPH, ABTS, and FRAP assays appeared in declining trends. Based on widely targeted metabolomics, 518, 443, and 507 differentially accumulated metabolites (DAMs) were screened in the initial storage period (CK0 vs. CK2), mid-storage period (CK2 vs. CK4), and the end of storage (CK4 vs. CK6), respectively.

In antigenotoxic activity, doses added with MMC were significantly lower than positive control (<i>p</i> &lt; 0.05).
