Abstract
The skin is the outermost anatomical barrier, which plays a vital role in the maintenance of internal homeostasis and protection against physical, chemical, and biological detractors. Direct contact with various stimuli leads to several physiological changes that are ultimately important for the growth of the cosmetic industry. Due to the consequences of using synthetic compounds in skincare and cosmeceutical-related industries, the pharmaceutical and scientific communities have recently shifted their focus to natural ingredients. The nutrient-rich value of algae, which are some of the most interesting organisms in marine ecosystems, has attracted attention. Secondary metabolites isolated from seaweeds are potential candidates for a wide range of economic applications, including food, pharmaceuticals, and cosmetics. An increasing number of studies have focused on polyphenol compounds owing to their promising biological activities against oxidation, inflammation, allergies, cancers, melanogenesis, aging, and wrinkles. This review summarizes the potential evidence of the beneficial properties and future perspectives of using marine macroalgae-derived polyphenolic compounds for advancing the cosmetic industry.

Aspirin-Triggered Resolvin D1 (AT-RvD1) Protects Mouse Skin against UVB-Induced Inflammation and Oxidative Stress. Molecules 2023; 28:molecules28052417. [PMID: 36903662 PMCID: PMC10005614 DOI: 10.3390/molecules28052417] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 02/27/2023] [Accepted: 03/01/2023] [Indexed: 03/09/2023] Open
Abstract
Intense exposure to UVB radiation incites excessive production of reactive oxygen species (ROS) and inflammation. The resolution of inflammation is an active process orchestrated by a family of lipid molecules that includes AT-RvD1, a specialized proresolving lipid mediator (SPM). AT-RvD1 is derived from omega-3, which presents anti-inflammatory activity and reduces oxidative stress markers. The present work aims to investigate the protective effect of AT-RvD1 on UVB-induced inflammation and oxidative stress in hairless mice. Animals were first treated with 30, 100, and 300 pg/animal AT-RvD1 (i.v.) and then exposed to UVB (4.14 J/cm2). The results showed that 300 pg/animal of AT-RvD1 could restrict skin edema, neutrophil and mast cell infiltration, COX-2 mRNA expression, cytokine release, and MMP-9 activity and restore skin antioxidant capacity as per FRAP and ABTS assays and control O2•- production, lipoperoxidation, epidermal thickening, and sunburn cells development. AT-RvD1 could reverse the UVB-induced downregulation of Nrf2 and its downstream targets GSH, catalase, and NOQ-1. Our results suggest that by upregulating the Nrf2 pathway, AT-RvD1 promotes the expression of ARE genes, restoring the skin's natural antioxidant defense against UVB exposition to avoid oxidative stress, inflammation, and tissue damage.

Abstract
Persimmon (Diospyros kaki Thunb.) fruits are a remarkable source of carotenoids, which have shown protective effects against UV radiation in bacteria, fungi, algae, and plants. The aim of this study was to analyze the photoprotection provided by an acetone extract, rich in carotenoids and obtained from byproducts derived from the persimmon juice industry, against UV-induced cell death in the keratinocyte HaCaT cell line. For this purpose, the cytotoxicity and phototoxicity of carotenoid extract, as well as its intracellular reactive oxygen species (ROS) scavenging and anti-adhesive activities towards HaCaT cells, were evaluated. The in vitro permeation test provided information about the permeability of the carotenoid extract. Persimmon extracts, rich in carotenoids (PEC), were absorbed by HaCaT keratinocyte cells, which reduced the UV-induced intracellular ROS production in treated cells. Thus, PEC exerted a photoprotective and regenerative effect on UV-irradiated HaCaT cells, and this protection was UV dose-dependent. No cytotoxic effect was observed in HaCaT cultures at the concentration tested. PEC treatment also stimulated the adhesion capacity of skin microbiome to HaCaT cells, while exhibiting a significant anti-adhesive activity against all tested pathogens. In conclusion, PEC showed potential for use as a functional ingredient in skin-care products.

Abstract
Nexrutine (NX), a marketable herbal extract from a traditional Chinese herbal plant, Phellodendron amurense, is majorly used for the resolution of inflammation, gastroenteritis, and some tissue-specific cancer. Strategies for the identification of the safety of anticancer solutions of plant origin are an important area of study. The present investigation assesses the single and repeated dose (28 days) toxicity of NX following OECD guidelines 425 and 407, respectively. Briefly, to identify acute toxic properties of NX, a dose of 2000 mg/kg b. wt was administered once orally. Simultaneously, repeated dose toxicity was evaluated through daily administration of the three different doses (250, 500, 750 mg/kg b. wt) of NX for 28days. The single administration of NX showed no signs of toxicity and morbidity, suggesting LD50 of NX more than 2000 mg/kg b. wt. Furthermore, repeated dose exposure of NX for 28 days did not show any sign of toxicity. Hematology, serum biochemistry, and histopathological analysis also did not show any significant abnormalities. However, a marginal decrease in triglyceride, cholesterol, and glucose levels along with mild tubular degeneration in the kidney was also noticed in the high dose NX treatment group. Overall, the findings of the study suggest that NX is safe for use up to 500 mg/kg b.wt. Single dose toxicity confirms LD50 of NX to be greater than 2000 mg/kg b. wt. Repeated dose toxicity study used three doses of NX (250, 500, 750 mg/kg b. wt). Minimal aberrations in hematology and biochemical parameters. Histopathology depicts mild tubular degeneration at a high dose in the kidney. No morbidity or mortality was recorded in both the experimental setups.

Abstract
Cordia verbenacea DC (Boraginaceae) is a flowering shrub found along the Brazilian Atlantic Forest, Brazilian coast, and low areas of the Amazon. The crude extract of its leaves is widely used in Brazilian folk medicine as an anti-inflammatory, both topically and orally. The aim of this study is to evaluate the activity of C. verbenacea ethanolic leaves extract (CVE) against UVB-triggered cutaneous inflammation and oxidative damage in hairless mice. CVE treatment recovered cutaneous antioxidant capacity demonstrated by scavenging ABTS+ free radical and iron-reducing antioxidant potential evaluated by FRAP. CVE also controlled the following UV-triggered events in the skin: reduced glutathione (GSH) depletion, catalase activity decrease, and superoxide anion (O⋅-) build-up. Furthermore, mice treated with CVE exhibited less inflammation, shown by the reduction in COX-2 expression, TNF-α, IL-1β, IL-6, edema, and neutrophil infiltration. CVE also regulated epidermal thickening and sunburn cells, reduced dermal mast cells, and preserved collagen integrity. The best results were obtained using 5% CVE-added emulsion. The present data demonstrate that topical administration of CVE presents photochemoprotective activity in a mouse model of UVB inflammation and oxidative stress. Because of the intricate network linking inflammation, oxidative stress, and skin cancer, these results also indicate the importance of further studies elucidating a possible role of C. verbenacea in the prevention of UVB-induced skin cancer and evaluating a potential synergy between CVE and sunscreens in topical products against UVB damaging effects to the skin.

Abstract
AIM Nexrutine, an herbal extract of Phellodendron amurense, has been found to play a tumor-suppressive role in many cancers. However, its role in the pathogenesis of gastric cancer remains unclear. MATERIALS AND METHODS Gastric cancer cells (SGC-7901 and MGC-803) were treated with nexrutine, and cell proliferation, invasion and apoptosis were analyzed. And the MGC-803 cells-derived xenograft mouse models were fed pelleted diet containing 600 mg/kg nexrutine for 21 days after inoculation. Mechanically, we focused on the influences of nexrutine on the levels and activation of STAT3 and NF-κB as well as their upstream regulator FAK. Additionally, we further verified whether nexrutine affected the proliferation, invasion and apoptosis of gastric cancer cells via FAK by upregulating FAK expression before nexrutine treatment. KEY FINDINGS We found nexrutine inhibited the viability, invasion, and expression levels of PCNA, CyclinD1 and Bcl-2, promoted the apoptosis and Bax expression, decreased levels of STAT3, phospho-STAT3, NF-κB p65, phospho-p65, FAK and phospho-FAK in gastric cancer cells. Overexpression of FAK reversed the impacts of nexrutine on the levels of STAT3, phospho-STAT3, NF-κB p65, phospho-p65, as well as the malignant characteristics of gastric cancer cells. Moreover, nexrutine suppressed tumor volumes and weights, and decreased expression and phosphorylation of FAK, STAT3 and NF-κB p65 in vivo. SIGNIFICANCE Nexrutine inhibited the malignant progression of gastric cancer via negatively regulating STAT3/NF-κB signaling pathway by suppressing FAK expression and activation.

Fucoxanthin and Rosmarinic Acid Combination Has Anti-Inflammatory Effects through Regulation of NLRP3 Inflammasome in UVB-Exposed HaCaT Keratinocytes. Mar Drugs 2019; 17:E451.

Abstract
Excessive exposure to ultraviolet (UV) radiation is the main risk factor to develop skin pathologies or cancer because it encourages oxidative condition and skin inflammation. In this sense, strategies for its prevention are currently being evaluated. Natural products such as carotenoids or polyphenols, which are abundant in the marine environment, have been used in the prevention of oxidative stress due to their demonstrated antioxidant activities. Nevertheless, the anti-inflammatory activity and its implication in photo-prevention have not been extensively studied. Thus, we aimed to evaluate the combination of fucoxanthin (FX) and rosmarinic acid (RA) on cell viability, apoptosis induction, inflammasome regulation, and anti-oxidative response activation in UVB-irradiated HaCaT keratinocytes. We demonstrated for the first time that the combination of FX and RA (5 µM RA plus 5 μM FX, designated as M2) improved antioxidant and anti-inflammatory profiles in comparison to compounds assayed individually, by reducing UVB-induced apoptosis and the consequent ROS production. Furthermore, the M2 combination modulated the inflammatory response through down-regulation of inflammasome components such as NLRP3, ASC, and Caspase-1, and the interleukin (IL)-1β production. In addition, Nrf2 and HO-1 antioxidant genes expression increased in UVB-exposed HaCaT cells pre-treated with M2. These results suggest that this combination of natural products exerts photo-protective effects by down-regulating NRLP3-inflammasome and increasing Nrf2 signalling pathway.
