Abstract
Curcumin and omega-3 polyunsaturated fatty acids (ω-3 PUFA) are multifunctional compounds which play an important role in Alzheimer's disease (AD) and little has been addressed about the role of these two compounds together in the progression of the disease. There is evidence of the beneficial effect of combined administration of ω-3 PUFA and other dietary supplements such as vitamins and polyphenols in the prevention of AD, although much remains to be understood about their possible complementary or synergistic activity. Therefore, the objective of this work is to review the research focused on studying the effect and mechanisms of action of curcumin, ω-3 PUFA, and the combination of these nutraceutical compounds, particularly on AD, and to integrate the possible ways in which these compounds can potentiate their effect. The most important pathophysiologies that manifest in AD will be addressed, in order to have a better understanding of the mechanisms of action through which these bioactive compounds exert a neuroprotective effect.

Diet Supplementation with Polyphenol-Rich Salicornia ramosissima Extracts Protects against Tissue Damage in Experimental Models of Cerebral Ischemia. Nutrients 2022; 14:nu14235077. [PMID: 36501107 PMCID: PMC9735563 DOI: 10.3390/nu14235077] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 11/22/2022] [Accepted: 11/25/2022] [Indexed: 12/05/2022] Open
Abstract
Strokes are the second most common cause of death worldwide and a leading cause of disability. Regular consumption of polyphenols has been shown to reduce the risk of suffering a cardiovascular event. For this reason, we have investigated the protective effect of Salicornia ramosissima, a seasonal halophyte that synthetizes high amounts of bioactive compounds, including polyphenols, in response to environmental stress. Aqueous, hydroalcoholic, and ethanolic extracts were prepared to investigate if dietary supplementation prior to ischemic challenge can prevent subsequent damage using two animal models. First, we screened the protective effect against hypoxia-reoxygenation in Drosophila melanogaster and observed that both ethanolic and hydroalcoholic extracts protected flies from the deleterious effects of hypoxia. Second, we confirmed the protective effect of S. ramosissima ethanolic extract against brain ischemia using the transient middle cerebral artery occlusion mice model. Four weeks of oral supplementation with the ethanolic extract before artery occlusion reduced infarct volume and lowered the plasma levels of the DNA peroxidant product 8-hydroxydeoxyguanosine. Phytochemical profiling of S. ramosissima ethanolic extract revealed 50 compounds. Thus, it represents a valuable source of bioactive compounds that show promising disease-modifying activities and could be further developed as an effective food supplement for the prevention or treatment of neurovascular disorders.

The Protective Effects of Nutraceutical Components in Methotrexate-Induced Toxicity Models—An Overview. Microorganisms 2022; 10:microorganisms10102053. [PMID: 36296329 PMCID: PMC9608860 DOI: 10.3390/microorganisms10102053] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Revised: 10/11/2022] [Accepted: 10/13/2022] [Indexed: 12/04/2022] Open
Abstract
There are multiple concerns associated with methotrexate (MTX), widely recognized for anti-neoplastic and anti-inflammatory effects in life-threatening disease conditions, i.e., acute lymphoblastic leukemia, non-Hodgkin’s lymphoma, psoriasis, and rheumatoid arthritis, due to long-term side effects and associated toxicity, which limits its valuable potential. MTX acts as an inhibitor of dihydrofolate reductase, leading to suppression of purine and pyrimidine synthesis in high metabolic and turnover cells, targeting cancer and dysregulated immune cells. Due to low discrimination between neoplastic cells and naturally high turnover cells, MTX is prone to inhibiting the division of all fast-dividing cells, causing toxicity in multiple organs. Nutraceutical compounds are plant-based or food-derived compounds, used for their preventive and therapeutic role, ascertained in multiple organ dysfunctions, including cardiovascular disease, ischemic stroke, cancer, and neurodegenerative diseases. Gut microbiota and microbiota-derived metabolites take part in multiple physiological processes, their dysregulation being involved in disease pathogenesis. Modulation of gut microbiota by using nutraceutical compounds represents a promising therapeutic direction to restore intestinal dysfunction associated with MTX treatment. In this review, we address the main organ dysfunctions induced by MTX treatment, and modulations of them by using nutraceutical compounds. Moreover, we revealed the protective mechanisms of nutraceuticals in MTX-induced intestinal dysfunctions by modulation of gut microbiota.

Abstract
Ligusticum chuanxiong Hort. (CX) is a medicinal and edible plant with a wide range of constituents of biological interest. Since the biomass of the non-medicinal parts of CX is huge, discarding them will cause a waste of resources. To expand the medicinal uses of CX, we comprehensively investigated the chemical diversity and efficacy of its different parts (rhizomes, fibrous roots, stems and leaves). 75 compounds in the volatile oil and 243 compounds in the methanol extracts (including 95 phthalides) obtained from CX were characterized by GC-MS and UHPLC/Q-Orbitrap MS analysis, respectively. Of 95 phthalides, 14 potential new compounds and 5 phthalide trimers were identified from CX for the first time. Phthalide monomers were more abundant in rhizomes and fibrous roots, and phthalide dimers or even phthalide trimers mainly in stems and leaves. By multivariate and univariate analyses, 22 and 24 different compounds were found in the volatile oils and the methanol extracts, respectively. In the bioactivity evaluation of different parts, stems and leaves showed the best antioxidant activity, fibrous roots showed the strongest vasodilator activity, and rhizomes showed the most significant anticoagulant activity, which was related to the different metabolites in different parts. Ultimately, this work revealed the similarities and differences of phytochemicals and bioactivities in different anatomical parts of CX. It might provide helpful evidence for the rational application of non-medicinal resources.

Abstract
In this Special Issue on "Nutraceuticals: Molecular and Functional Insights into how Natural Products Nourish the Brain", the editors bring together contributions from experts in nutraceutical research to provide a contemporary overview of how select chemically identified molecules from natural products can beneficially affect brain function at the molecular level. Other contributions address the holistic benefit of herbal medicines and their multi-targeted actions, which improve brain function in diverse cellular and animal models of brain injury. Not only are new targets for nutraceuticals reported, but their benefits on neurobehavioural problems are elucidated in conditions as diverse as obesity and menopause. Inflammation in neuropathologies, including Alzheimer's disease (AD), remains a huge focus and diverse nutraceuticals demonstrate therapeutic applicability via glial-mediated actions. While contrary actions should be borne in mind in the search for novel neurotherapeutics, the great promise offered by herbal medicines and their newly identified active principles offers unique options for the management of diverse neurological and psychiatric conditions.
