Special Issue Information

Dear Colleagues,

Aging is considered an inevitable multifactorial biological process that implicates genomic instability with altered cellular homeostasis and leads to a number of diseases. Although diverse biochemical and molecular pathways are implicated in this process, oxidative stress (OS) and inflammation are the hallmarks of aging. The uncontrolled production of free radical molecules affects the main cellular biomolecules such as lipids, proteins, and nucleic acids, and subsequently accelerates aging, including the onset and the progression of age-related diseases such as diabetes and cardiovascular disease. Thus, OS and inflammation have become major therapeutic targets to alleviate age-related complications. In fact, due to their robust antioxidant properties and minimal side effects, natural products have been increasingly explored with regard to their ameliorative effects against OS and inflammation to protect against cellular damages. Importantly, due to their increased consumption from diet and their potential development as nutraceuticals, research into naturally derived bioactive compounds has become essential to establish their therapeutic properties as anti-aging agents. Beyond their direct effects on aging, this Special Issue is open to contributions on the impact of natural products (toxicological and pharmacological aspects) on complications linked with aging, such as cancer, diabetes mellitus, and cardiovascular diseases, from preclinical models to clinical settings.

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. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs).

The consumption of food-derived products, including the regular intake of pepper, is increasingly evaluated for its potential benefits in protecting against diverse metabolic complications. The current study made use of prominent electronic databases including PubMed, Google Scholar, and Scopus to retrieve clinical evidence linking the intake of black and red pepper with the amelioration of metabolic complications. The findings summarize evidence supporting the beneficial effects of black pepper (Piper nigrum L.), including its active ingredient, piperine, in improving blood lipid profiles, including reducing circulating levels of total cholesterol, low-density lipoprotein cholesterol, and triglycerides in overweight and obese individuals. The intake of piperine was also linked with enhanced antioxidant and anti-inflammatory properties by increasing serum levels of superoxide dismutase while reducing those of malonaldehyde and C-reactive protein in individuals with metabolic syndrome. Evidence summarized in the current review also indicates that red pepper (Capsicum annum), together with its active ingredient, capsaicin, could promote energy expenditure, including limiting energy intake, which is likely to contribute to reduced fat mass in overweight and obese individuals. Emerging clinical evidence also indicates that pepper may be beneficial in alleviating complications linked with other chronic conditions, including osteoarthritis, oropharyngeal dysphagia, digestion, hemodialysis, and neuromuscular fatigue. Notably, the beneficial effects of pepper or its active ingredients appear to be more pronounced when used in combination with other bioactive compounds. The current review also covers essential information on the metabolism and bioavailability profiles of both pepper species and their main active ingredients, which are all necessary to understand their potential beneficial effects against metabolic diseases.
