Sea cucumber ( Stichopus japonicus ) intestine was utilized as an example, undergoing gastrointestinal digestion followed by de novo sequencing to predict potential peptide sequences. These peptides were efficiently synthesized for the first time using a readily accessible filter pipette tip as parallel reaction vessels, eliminating the use of any expensive equipment. This method enabled the synthesis of numerous peptides at a milligram scale with microfluidic amino acid flowing through the solid resin. After high‐throughput activity screening, peptide LSPGV was shown to exhibit the most potent antioxidant activity (DPPH radical scavenging activity [DRSA]: 88.96%) and strongest acetylcholinesterase (AChE) inhibition (IC 50 of 7.32 μM) simultaneously. The reduction in paralysis, amyloid‐β (Aβ) aggregation, and AChE activity in vivo was further confirmed in an animal model, Caenorhabditis elegans . 3D structure simulation and molecular docking study were also conducted for LSPGV to illustrate its potential conformation and favorable binding interactions with AChE. As a candidate for Alzheimer's disease (AD) treatment, LSPGV significantly enhances the value of sea cucumber intestine by‐products.","PeriodicalId":19825,"journal":{"name":"Peptide Science","volume":"117 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147331619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, goat casein, an abundant by‐product of the dairy industry, emerges as a valuable source of BAPs. The present study undertook a meticulous evaluation of the bioactive potentials of goat casein‐derived peptides through an integrated approach combining computational simulations, high‐throughput screening, and molecular docking techniques. The initial phase involved the enzymatic digestion of goat milk casein using trypsin, followed by the identification of peptides via liquid chromatography–tandem mass spectrometry (LC–MS/MS), uncovering a total of 597 peptides. Subsequent prioritization using the PeptideRanker algorithm identified 70 peptides exhibiting potential bioactivity, as denoted by scores above 0.8. Advanced screening employing the BIOPEP database and the AutoDock and CAMPR4 tools facilitated the elucidation of 16 antioxidant, 59 hypotensive, 63 hypoglycemic, 70 hypolipidemic, and 25 antimicrobial peptides. Molecular docking studies further elucidated the spontaneous nature of the interactions between the peptides and their respective receptors, predominantly mediated by hydrogen bonding and hydrophobic interactions. Four peptides specifying all activities simultaneously were synthesized, and their activities were verified by in vitro experiments. These results not only highlight an effective strategy for the high‐throughput screening of goat casein‐derived peptides but also underscore the potential of utilizing casein as a viable source of functional food ingredients. This study thereby contributes significantly to the expanding field of functional food research, suggesting a sustainable approach to explore the potential of dairy by‐products.","PeriodicalId":19825,"journal":{"name":"Peptide Science","volume":"117 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/pep2.24383","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147330769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Remarkably, our results demonstrate that our designed molecules adhere to Lipinski's rule and comply with essential physiochemical and druggable properties, affirming the promise of these compounds. Ligand MS60 emerges as a lead, showcasing the most substantial interaction with the EGFR receptor, underscored by its impressive docking score of −8.199 kcal/mol. Furthermore, molecular dynamics simulations conducted via GROMACS corroborate the stability of the MS60‐EGFR complex, portraying minimal fluctuations. This assertion is further validated through MMPBSA, PCA analysis, DCCM, and FEL studies, underscoring the robustness of our findings. We have designed the pharmacophore model to unravel critical steric and electronic attributes essential for effective supramolecular interactions with the EGFR receptor.

Substitution of D‐Ile at position 7 with D‐Arg improved membrane permeability and enhanced potency against HT144 cells via a mode‐of‐action that includes perturbation of mitochondrial membrane potential.

Supplementation of this metal is not straightforward because of several factors like phytates and interference of other minerals during gastrointestinal digestion. For the last several years, intensive research has been developing new forms of zinc supplements based on zinc‐binding peptides from food products. Except for the advantages of supplementation, zinc‐peptide complexes are expected to be drug candidates against various diseases. Zinc supplementation can be improved by protein hydrolysates and peptides due to their zinc‐binding ability. They enhance zinc supplementation and contribute to preventing conditions leading to zinc deficiency that cause various diseases. Research on food‐derived zinc‐binding peptides is progressing in two directions: the isolation and identification of individual peptides (1) and the preparation of zinc complexes of protein hydrolysates (2). Both approaches are primarily aimed at developing effective mineral supplements, although some work on the second approach is also related to nutrition and therapy. Because zinc–protein hydrolysate complexes are nonstandardized mixtures of peptides, their biological activity mechanisms can be difficult to study. Therefore, it is important to focus more research on the biological activity of individual zinc‐binding complexes and their zinc complexes. This work reviewed recent advances in isolating and identifying zinc‐binding peptides from food sources, preparing protein hydrolysate–zinc complexes, and their biological activities. The established sequences of zinc‐binding peptides have been compiled into a table to review their amino‐acid composition and sequence. We also highlighted approaches for isolating and determining the zinc‐binding capacity of peptides in this class.

A series of constrained peptides were designed to mimic the alpha‐helical protein interaction interface between the LRRK2 armadillo region and the death domain of FADD. These peptide‐based protein–protein interaction inhibitors significantly reduced this interaction and blocked apoptotic death of primary neurons expressing G2019S‐LRRK2.
