Topical Collection Information

Dear Colleagues,

To address the current challenges in the scientific validation of the functionality of bioactive compounds for health and well-being, there is a need for novel approaches and research results focused on the clarification, elucidation, and investigation of the structure–function relationships and the design of better dietary and clinical interventions to back up their potential functionality. Therefore, in this Special Issue of IJMS, we aim to assemble a topical collection of publications, communications, insightful and critical information, research results, and opinions on the state-of-the-art investigations using in vitro and in vivo models as preclinical research stages for the investigation of potentially bioactive compounds.

Moreover, we aim to provide an ideal platform for the discussion of the findings of epidemiological and clinical studies lacking this necessary preclinical information to foster future validation of functionalities. Many clinical results are lacking enough strength to validate a “functional” compound, ingredient, or food because of the gap of knowledge on the structure–function relationship due to insufficient bioactivity demonstration, and this Topical Collection aims to make results that fill this gap available in open access so that the research community worldwide may benefit.

We welcome the submission of studies considering the development, establishment, and validation of in vitro and in vivo models for the study of health-promoting bioactive compounds at the physiological, biochemical, and molecular levels in order to find the connection between the compounds in their natural matrices (extracted, purified, or formulated) and the potential effects on health and well-being through improvements in bioaccessibility, bioavailability, metabolism, and bioactivity.

Evidence on the Bioaccessibility of Glucosinolates and Breakdown Products of Cruciferous Sprouts by Simulated In Vitro Gastrointestinal Digestion

Cruciferous vegetables are gaining importance as nutritious and sustainable foods, rich in phytochemical compounds such as glucosinolates (GSLs). However, the breakdown products of these sulfur-based compounds, mainly represented by isothiocyanates (ITC) and indoles, can contribute to human health. In the human digestive system, the formation of these compounds continues to varying extents in the different stages of digestion, due to the contact of GSLs with different gastric fluids and enzymes under the physicochemical conditions of the gastrointestinal tract. Therefore, the aim of the present work was to uncover the effect of gastrointestinal digestion on the release of glucosinolates and their transformation into their bioactive counterparts by applying a simulated in vitro static model on a range of brassica (red radish, red cabbage, broccoli, and mustard) sprouts. In this sense, significantly higher bioaccessibility of ITC and indoles from GSLs of red cabbage sprouts was observed in comparison with broccoli, red radish, and mustard sprouts, due to the aliphatic GSLs proportion present in the different sprouts. This indicates that the bioaccessibility of GSLs from Brasicaceae sprouts is not exclusively associated with the initial content of these compounds in the plant material (almost negligible), but also with the release of GSLs and the ongoing breakdown reactions during the gastric and intestinal phases of digestion, respectively. Additionally, aliphatic GSLs provided higher bioaccessibility of their corresponding ITC in comparison to indolic and aromatic GSLs. Full article

Methicillin-resistant Staphylococcus aureus (MRSA) is a major nosocomial pathogen worldwide and has acquired multiple resistance to a wide range of antibiotics. Hence, there is a pressing need to explore novel strategies to overcome the increase in antimicrobial resistance. The present study aims to investigate the efficacy and mechanism of plant-derived antimicrobials, trans-cinnamaldehyde (TCA) in decreasing MRSA’s resistance to eight conventional antibiotics. A checkerboard dilution test and time–kill curve assay are used to determine the synergistic effects of TCA combined with the antibiotics. The results indicated that TCA increased the antibacterial activity of the antibiotics by 2-16-fold. To study the mechanism of the synergism, we analyzed the mecA transcription gene and the penicillin-binding protein 2a level of MRSA treated with TCA by quantitative RT-PCR or Western blot assay. The gene transcription and the protein level were significantly inhibited. Additionally, it was verified that TCA can significantly inhibit the biofilm, which is highly resistant to antibiotics. The expression of the biofilm regulatory gene hld of MRSA after TCA treatment was also significantly downregulated. These findings suggest that TCA maybe is an exceptionally potent modulator of antibiotics. Full article
