Special Issue Information

Dear Colleagues,

Bioactive compounds are extra-nutritional components that can be found in plant foods, offering health benefits beyond the basic nutritional value. Moreover, polypeptides represent a class of nutrients that has exhibited an increasingly positive impact on the lives of its consumers. In fact, on the one hand, they are the main sources of amino acids, and on the other hand, there is growing clinical evidence that peptides from natural sources provide health benefits. Reduction in cardiometabolic risk factors, increased muscle mass and strength, increased metabolism and increased fat burning, the regulation of blood circulation pressure, the functional benefits of lean mass such as increased leg power or gait speed, and improved bone density are some of the effects on human health caused by peptides.

For many years, pharmaceutical research has focused on plants as a source of new drugs or lead compounds for the design of therapeutic agents. Furthermore, ever-increasing attention is being paid to the positive effects of a diet rich in foods containing bioactive compounds. This Special Issue aims to include original research and review articles that discuss the chemical and biological characterization of bioactive compounds in plant foods. The study of the bioactivities of molecules, their structure–activity relationship, and the molecular mechanisms underlying their biological action are also suitable for inclusion in this Special Issue.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nutrients is an international peer-reviewed open access semimonthly journal published by MDPI.

Corn peptide (CP) is a short, naturally occurring, and physiologically active peptide generated from corn-protease-catalyzed hydrolysis. CP plays a role in preventing obesity-related disorders, but its impact on reducing inflammation is unknown. Hence, this study examined the possible protective effects of corn peptide powder (CPP) against the harmful effects of lipopolysaccharide (LPS), with a particular emphasis on reducing oxidative damage and inflammation in adipocytes. Hence, mature 3T3-L1 adipocytes underwent exposure to 10 ng/mL LPS, with or without CPP (10 and 20 μg/mL). LPS stimulation increased reactive oxygen species and superoxide anion generation. However, this effect was reduced in a dose-dependent manner by pretreatment with CPP. CPP treatment elevated the mRNA expressions of the antioxidant enzymes manganese superoxide dismutase (mnSOD) and glutathione peroxidase 1 (Gpx1) while reducing the mRNA expressions of the cytosolic reactive oxygen species indicators p40 and p67 (NADPH oxidase 2). In addition, CPP inhibited the monocyte chemoattractant protein-1, tumor necrosis factor-alpha, Toll-like receptor 4, and nuclear factor kappa B mRNA expressions induced by LPS. These findings demonstrate that CPP may ameliorate adipocyte dysfunction by suppressing oxidative damage and inflammatory responses through a new mechanism known as Toll-like receptor 4/nuclear factor kappa B-mediated signaling.
