Hesperidin, Hesperetin, Rutinose, and Rhamnose Act as Skin Anti-Aging Agents. Molecules 2023; 28:molecules28041728. [PMID: 36838716 PMCID: PMC9963045 DOI: 10.3390/molecules28041728] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 02/08/2023] [Accepted: 02/09/2023] [Indexed: 02/15/2023] Open
Abstract
Aging is a complex physiological process that can be accelerated by chemical (high blood glucose levels) or physical (solar exposure) factors. It is accompanied by the accumulation of altered molecules in the human body. The accumulation of oxidatively modified and glycated proteins is associated with inflammation and the progression of chronic diseases (aging). The use of antiglycating agents is one of the recent approaches in the preventive strategy of aging and natural compounds seem to be promising candidates. Our study focused on the anti-aging effect of the flavonoid hesperetin, its glycoside hesperidin and its carbohydrate moieties rutinose and rhamnose on young and physiologically aged normal human dermal fibroblasts (NHDFs). The anti-aging activity of the test compounds was evaluated by measuring matrix metalloproteinases (MMPs) and inflammatory interleukins by ELISA. The modulation of elastase, hyaluronidase, and collagenase activity by the tested substances was evaluated spectrophotometrically by tube tests. Rutinose and rhamnose inhibited the activity of pure elastase, hyaluronidase, and collagenase. Hesperidin and hesperetin inhibited elastase and hyaluronidase activity. In skin aging models, MMP-1 and MMP-2 levels were reduced after application of all tested substances. Collagen I production was increased after the application of rhamnose and rutinose.

Neuroprotection by Skimmianine in Lipopolysaccharide-Activated BV-2 Microglia. Molecules 2023; 28:molecules28031317. [PMID: 36770987 PMCID: PMC9920223 DOI: 10.3390/molecules28031317] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 01/18/2023] [Accepted: 01/23/2023] [Indexed: 02/03/2023] Open
Abstract
Skimmianine is a furoquinoline alkaloid which is found in the Zanthoxylum genus and also in other plants of the Rutaceae family. This study evaluated the effects of skimmianine on the production of pro-inflammatory mediators in LPS-activated BV-2 microglia. Cultured BV-2 cells were treated with skimmianine (10, 20 and 30 μM), followed by stimulation with LPS (100 ng/mL). Levels of TNFα and IL-6 in cell supernatants were measured using ELISA, while NO and PGE2 levels were evaluated with Griess assay and EIA, respectively. Western blotting was used to determine the protein expression of iNOS, COX-2, phospho-p65 and phospho-IκBα. Results showed that Skimmianine reduced LPS-induced elevated the secretion of TNFα, IL-6, NO, and PGE2, as well as the increased protein expression of iNOS and COX-2. Experiments to elucidate the mechanisms of the anti-neuroinflammatory activity of skimmianine revealed the significant inhibition of LPS-induced increased NF-κB-mediated luciferase activity. Pre-treatment with skimmianine also reduced LPS-induced the increased phosphorylation of NF-κB/p65 and IκBα proteins. Furthermore, skimmianine interfered with the binding capacity of NF-κB to consensus sites. Skimmianine pre-treatment protected HT-22 cells from toxicity induced by microglia-conditioned media, as well as increasing MAP-2 expression. The results of this study suggest that skimmianine inhibits neuroinflammation in LPS-activated microglia by targeting the NF-κB activation pathway. Skimmianine also produced neuroprotection against neurotoxicity induced by microglia-conditioned media.

Abstract
BACKGROUND Excessive exposure to ultraviolet radiation has harmful effects on human skin. At present, synthetic and mineral types of sunscreens used to protect against these harmful damages have been reported to cause negative health and environmental effects. The studies involving characterization and isolation of phytoconstituents from natural botanical sources are important to discover their potential beneficial effects on sunscreen development AIM: This systematic review provides specific and compiled information on the photoprotective properties of natural botanical sources for sunscreen development. The efforts in research and innovation are essential to ensure the safety and sustainability of plant-based sunscreen products. METHODS In this review, a total of 35 articles were selected using the Scopus database based on the inclusion and exclusion criteria RESULT: The significant correlation between total phenolic content, total flavonoid content, antioxidant activities, and sun protection factor were shown in these studies which confirmed the potential benefits of natural plants in sunscreen development. CONCLUSIONS In addition, natural botanical sources also exhibit excellent anti-tyrosinase, anti-aging, and anti-inflammatory activities. However, the biological activities of plants were dependent on the solvents used for extraction.

Photoprotective Potential, Cytotoxicity, and UPLC-QTOF/MS Analysis on Bioactive Solvent Fractions of Moringa concanensis Nimmo Bark. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:3781189. [PMID: 35502171 PMCID: PMC9056231 DOI: 10.1155/2022/3781189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 04/03/2022] [Accepted: 04/05/2022] [Indexed: 11/18/2022]
Abstract
Moringa concanensis Nimmo (Moringaceae) belongs to the same family of M. oleifera (miracle tree) and is a medicinal plant traditionally used by Indians to treat various ailments related to diabetes, tumours, inflammation, and blood pressure. Despite its versatility, the photoprotective properties of the plant remain unclear. This study revealed the UV-protective properties of its methanol bark extract and respective subfractions, chloroform, hexane, and ethyl acetate through total phenolic and flavonoid content (TPC & TFC), antioxidant (DPPH), sun protecting factor (SPF) value, and UV absorption spectra analysis. This study also investigated on the inhibitory effect of the tested samples on collagenases and elastase, which are well-known for their role in the skin. The cytotoxic and H2O2 scavenging properties of M. concanensis in 3T3-L1 cells were explored. Finally, the phytochemical profiling of the active fraction was conducted through UPLC-QTOF/MS analysis. Among the tested fractions, the chloroform fraction of M. concanensis showed the highest TPC (30.92 ± 0.71 mg GAE/DW), TFC (29.05 ± 0.09 mg QE/DW), and antioxidant properties (IC50-6.616 ± 1.90 μgml−1). Additionally, chloroform fraction demonstrated the highest SPF value, 10.46 at 200 μgml−1, compared to the other tested fractions. All the fractions showed a broad absorption spectrum covering both UVA and UVB ranges. The chloroform fraction of M. concanensis also showed collagenase (50%) and elastase (IC50-2.95 ± 1.23 μgml−1) inhibition properties similar to the positive control. Cytotoxic results revealed that the chloroform fraction of M. concanensis prevented the H2O2-induced oxidative damage in 3T3-L1 cells even at lower concentrations (1.56 μgml−1). UPLC-QTOF/MS analysis tentatively identified the presence of bioactive flavonoids and phenolics such as astragalin, quercetin, isoquercetin, and caffeic acid in the active fraction of M. concanensis bark. Overall, it is suggested that the chloroform fraction of M. concanensis bark has the potency to be used as an active ingredient in sunscreen products.

Abstract
Ultraviolet (UV) B exposure is a prominent cause of skin aging and a contemporary subject of interest. The effects are progressing through the generation of reactive oxygen species (ROS) that alter cell signaling pathways related to inflammatory responses. The present study evaluates the protective effects of (7aR)-6-hydroxy-4,4,7a-trimethyl-6,7-dihydro-5H-1-benzofuran-2-one (HTT) isolated from the edible brown algae Sargassum horneri against UVB protective effects in human dermal fibroblasts (HDFs). HTT treatment dose-dependently suppressed intracellular ROS generation in HDFs with an IC50 of 62.43 ± 3.22 µM. HTT abated UVB-induced mitochondrial hyperpolarization and apoptotic body formation. Furthermore, UVB-induced activation of key nuclear factor (NF)-κB and mitogen-activated protein kinase signaling proteins were suppressed in HTT treated cells while downregulating pro-inflammatory cytokines (interleukin-1β, 6, 8, 33 and tumor necrosis factor-α). Moreover, HTT treatment downregulated matrix metalloproteinase1, 2, 3, 8, 9 and 13 that was further confirmed by the inhibition of collagenase and elastase activity. The evidence implies that HTT delivers protective effects against premature skin aging caused by UVB exposure via suppressing inflammatory responses and degradation of extracellular matrix (ECM) components. Extensive research in this regard will raise perspectives for using HTT as an ingredient in UV protective ointments.

Abstract
Matrix metalloproteinases (MMPs) are a group of zinc-dependent metalloendopeptidases that are responsible for the degradation, repair, and remodeling of extracellular matrix components. MMPs play an important role in maintaining a normal physiological function and preventing diseases, such as cancer and cardiovascular diseases. Natural products derived from plants have been used as traditional medicine for centuries. Its active compounds, such as catechin, resveratrol and quercetin, are suggested to play an important role as MMPs inhibitors, thereby opening new insights into their applications in many fields, such as pharmaceutical, cosmetic, and food industries. This review summarises the current knowledge of plant-derived natural products with MMP-modulating activities. Most of the reviewed plant-derived products exhibit an inhibitory activity on MMPs. Amongst MMPs, MMP-2 and MMP-9 are the most studied. The expression of MMPs is inhibited through respective signaling pathways, such as MAPK, NF-κB and PI3 kinase pathways, which contribute to the reduction in cancer cell behaviors, such as proliferation and migration. Most studies have employed in vitro models, but a limited number of animal studies and clinical trials have been conducted. Even though plant-derived products show promising results in modulating MMPs, more in vivo studies and clinical trials are needed to support their therapeutic applications in the future.

Guiqi Baizhu Decoction Alleviates Radiation Inflammation in Rats by Modulating the Composition of the Gut Microbiota. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:9017854. [PMID: 33133218 PMCID: PMC7591278 DOI: 10.1155/2020/9017854] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Revised: 09/07/2020] [Accepted: 09/10/2020] [Indexed: 12/13/2022]
Abstract
The gut microbiota is important in metabolism and immune modulation, and compositional disruption of the gut microbiota population is closely associated with inflammation caused by ionizing radiation (IR). Guiqi Baizhu decoction (GQBZD) is a medicinal compound used in traditional Chinese medicine with anti-inflammatory and antioxidation effects, especially in the process of radiotherapy. However, the effect of GQBZD on reducing the damage to the normal immune system in radiotherapy remains unclear. Here, we show that GQBZD reduces body weights, water intake, food intake, diarrhea level and quality of life score, and inflammation and enhances immunity function in rats treated with X-ray radiation. Meanwhile, our data indicate that GQBZD not only reverses IR-induced gut dysbiosis as indicated change of α-diversity and β-diversity of microbiota, the composition of Desulfovibrio, Bacteroides, and Parabacteroides, except for Roseburia and Lachnoclostridium, but also maintains intestinal barrier integrity and promoting the formation of short-chain fatty acids (SCFAs). GQBZD can also reduce the level of phosphorylation P65 (p-P65). Our results demonstrate that GQBZD can significantly alleviate the inflammatory responses and improve the immune damage against IR, and may be used as prebiotic agents to prevent gut dysbiosis and radiation-related metabolic disorders in radiotherapy.

Abstract
Chronic exposure to solar radiation is related to an increased incidence of various skin disorders, including premature skin aging and melanoma and non-melanoma skin cancers. Ultraviolet (UV) photons in particular are responsible for skin damage. Solar UV photons mainly belong to UVA wavebands, however UVA radiation has been mostly ignored for a long time. At the cellular level, UVA photons mainly provoke indirect oxidative damage to biomolecules via the massive generation of unstable and highly reactive compounds. Human skin has several effective mechanisms that forestall, repair and eliminate damage caused by solar radiation. Regardless, some damage persists and can accumulate with chronic exposure. Therefore, conscious protection against solar radiation (UVB+UVA) is necessary. Besides traditional types of photoprotection such as sunscreen use, new strategies are being searched for and developed. One very popular protective strategy is the application of phytochemicals as active ingredients of photoprotection preparations instead of synthetic chemicals. Phytochemicals usually possess additional biological activities besides absorbing the energy of photons, and those properties (e.g. antioxidant, anti-inflammatory) magnify the protective potential of phytochemicals and extracts. Therefore, compounds of natural origin are in the interest of researchers as well as developers. In this review, only studies on UVA protection with well-documented experimental conditions are summarized. This article includes 17 well standardized plant extracts (Camellia sinensis (L.) Kuntze, Silybum marianum L. Gaertn., Punica granatum L., Polypodium aureum L., Vaccinium myrtillus L., Lonicera caerulea L., Thymus vulgaris L., Opuntia ficus-indica (L.)

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hypericum olympicum L. (Hypericaceae) flowering aerial parts has been utilized in Turkish folk medicine as a remedy against inflamed skin problems. AIM OF THE STUDY This study was designed to state the effect of H. olympicum on dermatological problems. For this purpose effect of the plant extract on the DNA strand break and matrix metalloproteinase (MMP)-9 activity of human dermal fibroblast (HDFs) cells irradiated with UVB as well as antioxidant activity potential were studied. MATERIALS AND METHODS The methanolic extract of Hypericum olympicum (HOM) was prepared by maceration at room temperature. DNA damage and increased MMP-9 activity in HDFs were induced by UVB irradiation. The cell viability was measured by water-soluble tetrazolium salt (WST)-1 assay. The effects on DNA strand break was investigated by single gel electrophoresis (commonly known as Comet assay), while MMP-9 activity was observed by gelatin zymography assay. In vitro antioxidant tests were performed to indicate the effect on reactive oxygen species (ROS). The major metabolites were identified and their concentrations were measured by high performance thin layer chromatography (HPTLC). RESULTS HOM was found to recover DNA damage dose-dependently. The enzymatic activity of MMP-9 was inhibited almost 100% by the treatment of 1.5 mg/mL of the extract. It also enhanced cell proliferation in those cells, and also it was shown to possess antioxidant activity. The major metabolites of HOM were identified as chlorogenic acid and quercetin glycosides (rutin, hyperoside, isoquercitrin). CONCLUSION Experimental studies have proven the traditional use of Hypericum olympicum in inflamed skin problems acting by inhibition of the inflammatory pathway and recovery of DNA damage induced experimentally.

Abstract
Lung cancer in humans is majorly represented by non-small cell lung cancer cells, and there is a constant search for an efficient therapeutic approach. This study aims to find the anti-proliferative and apoptotic effects of matricin on H1299 cells via activation of MAPK pathway. Non-small cell H1299 cells were subjected to viability analysis with MTT assay and anti-proliferation analysis with different concentrations of matricin. Apoptosis was determined with annexin V/propidium iodide (PI) and flow cytometric analysis. Analysis of oxidative stress markers, reduced glutathione, lipid peroxidation (LPO), superoxide dismutase (SOD), and catalase (CAT) activities were done using standard assay kits. Apoptosis enzymes caspase-3, caspase-8, and caspase-9 levels were measured using colorimetric kit analysis. Western blot analysis on apoptotic proteins was performed to determine the involvement of MAPK pathway activation in apoptosis. Matricin significantly ( P < 0.01) exerted anti-proliferative activities on H1299 cells in a dose-dependent manner. Flow cytometric apoptosis analysis showed increasing concentrations of matricin had increased apoptosis ( P < 0.01) in the H1299 cells. Levels of oxidative stress markers were altered significantly ( P < 0.01) by matricin. Caspase-3, caspase-8, and caspase-9 levels were significantly increased ( P < 0.01) in matricin-treated H1299 cells. Western blot analysis showed decreased expression of anti-apoptotic Bcl-2, increased expressions of Bax and phosphorylated JNK, ERK 1/2, and p-38 MAPK proteins in matricin-treated H1299 cells. Matricin has significant anti-proliferative and apoptosis-inducing effects via activation of MAPK pathway in non-small cell lung cancer cells.

Abstract
Members of the matrix metalloproteinase (MMP) family have biological functions that are central to human health and disease, and MMP inhibitors have been investigated for the treatment of cardiovascular disease, cancer and neurodegenerative disorders. The outcomes of initial clinical trials with the first generation of MMP inhibitors proved disappointing. However, our growing understanding of the complexities of the MMP function in disease, and an increased understanding of MMP protein architecture and control of activity now provide new opportunities and avenues to develop MMP-focused therapies. Natural products that affect MMP activities have been of strong interest as templates for drug discovery, and for their use as chemical tools to help delineate the roles of MMPs that still remain to be defined. Herein, we highlight the most recent discoveries of structurally diverse natural product inhibitors to these proteases.

Abstract
Ultraviolet B (UVB) irradiation increases the risk of various skin disorders, resulting in apoptosis, autophagy and oxidative stress and thereby promoting the risk of skin photoaging and carcinogenesis. The use of photochemoprotectors including natural products with antioxidant properties represents an effective strategy for preventing UVB-induced skin injury. Isoorientin (Iso), as a flavonoid compound, could be extracted from several plant species and possesses multiple biological activities. However, its role in regulating UVB-induced skin damage is little to be reported. In the study, we found that Iso treatment could protect human dermal fibroblasts (HDFs) against the effects of UVB irradiation by improving cell viability, suppressing MMP1 and MMP3 expression, inhibiting oxidative stress and inducing autophagy. In addition, Iso reduced UVB-triggered apoptosis, as evidenced by the decreased Caspase-3 activity in vitro. Furthermore, Iso was functioned as reactive oxygen species (ROS) scavenger that markedly hindered c-Jun N-terminal kinases (JNK) signaling activation in UVB-treated HFDs. Importantly, promoting JNK activity restored matrix metalloproteinase (MMP)-1/3 expression in Iso-incubated cells with UVB stimulation. Meanwhile, UVB exposure to the skin of mice and subsequent topical application of Iso delayed the progression of skin damage, resulting in autophagy and blocking the JNK activation and ROS production. In conclusion, these results indicated the photoprotective role of Iso and demonstrated that Iso could also be potentially used as an agent against UVB-stimulated skin damage.
