Kumar NS, Reddy N, Kumar H, Vemireddy S. Immunomodulatory Plant Natural Products as Therapeutics against Inflammatory Skin Diseases. Curr Top Med Chem 2024; 24:1013-1034. [PMID: 38485678 DOI: 10.2174/0115680266277952240223120435] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 12/30/2023] [Accepted: 01/11/2024] [Indexed: 07/16/2024]
Abstract
Frequently occurring inflammatory skin conditions such as psoriasis, dermatitis, acne, including skin cancer, wounds and other disorders arising out of premature skin aging, deteriorate skin health and adversely impact human life. Even though several synthetic compounds have evolved for treating these skin conditions, natural-product-based therapeutics are gaining popularity with growing evidence of their efficacy and safety for treating skin disorders. Many of these inflammatory skin diseases have underlying disturbances in our immune system and immunomodulatory natural products provide solutions for their effective treatment and aid in understanding the underlying mechanism of such inflammatory skin conditions. Based on this premise, the present review summarizes the possible application of plant-derived immunomodulatory compositions and single molecules for treating inflammatory skin conditions. In vitro, in vivo and mechanistic studies reported the application of selected plant-derived natural products for the treatment of inflammatory skin disorders including, cancer and infections. Several online databases including PubMed, Google Scholar, and Science Direct have been searched for gathering the information covered in this review. Empirical studies demonstrated that most of these natural compounds exhibited therapeutic properties through their immunomodulatory and anti-inflammatory potential supplemented often with anti-microbial, anti-neoplastic, and anti- oxidant activities. Overall, plant-based natural products discussed here are capable of modulating the immune system to minimize or completely suppress the pro-inflammatory markers, scavenge free radicals (ROS), prevent bacteria, fungal, and virus-derived skin infections and often regress skin cancer through the induction of apoptosis. The challenges and opportunities associated with the application of plant-based immunomodulators for skin applications and their safety considerations are also discussed here. The present study indicated that immunomodulatory plant natural products being biologically validated ligands against various biological targets manifested in inflammatory skin diseases, offer an effective, safe and affordable treatment for such disorders affecting skin health. However, further clinical evaluations are needed to substantiate these findings.

Int J Mol Sci 2023; 24:15854. [PMID: 37958837 PMCID: PMC10650503 DOI: 10.3390/ijms242115854] [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: 10/05/2023] [Revised: 10/24/2023] [Accepted: 10/30/2023] [Indexed: 11/15/2023] Open
Abstract
The growing concern regarding the adverse effects of synthetic UV filters found in sunscreens has spurred significant attention due to their potential harm to aquatic ecosystems and human health. To address this, the present study aimed to extract and microencapsulate sensitive bioactive compounds derived from by-product onion peel (OP) by molecular inclusion using β-cyclodextrin as the wall material. Identification and quantification of bioactive compounds within the extract were conducted through high-performance liquid chromatography (HPLC-DAD) analysis, revealing quercetin and resveratrol as the primary constituents. The photoprotection capacity, evaluated by the sun protection factor (SPF), revealed a protection factor comparable to the value for a synthetic UV filter. The produced microparticles presented high antioxidant capacity, significant photoprotection capacity, encapsulation efficiency of 91.8%, mean diameter of 31 μm, and polydispersity of 2.09. Furthermore, to comprehensively evaluate the performance of OP extract and its potential as a natural UV filter, five O/W emulsions were produced. Results demonstrated that microparticles displayed superior ability in maintaining SPF values over a five-week period. Photoprotection evaluation-skin reactivity tests revealed that both extract and microparticles absorb UV radiation in other regions of UV radiation, revealing their potential to be used as a natural UV filter to produce a sustainable and eco-friendly value-added sunscreen.

Abstract
Exposure to sun radiation leads to higher risk of sunburn, pigmentation, immunosuppression, photoaging and skin cancer. In addition to ultraviolet radiation (UVR), recent research indicates that infrared radiation (IR) and visible light (VIS) can play an important role in the pathogenesis of some of these processes. Detrimental effects associated with sun exposure are well known, but new studies have shown that DNA damage continues to occur long after exposure to solar radiation has ended. Regarding photoprotection strategies, natural substances are emerging for topical and oral photoprotection. In this sense, Fernblock®, a standardized aqueous extract of the fern Polypodium Leucotomos (PLE), has been widely administered both topically and orally with a strong safety profile. Thus, this extract has been used extensively in clinical practice, including as a complement to photodynamic therapy (PDT) for treating actinic keratoses (AKs) and field cancerization. It has also been used to treat skin diseases such as photodermatoses, photoaggravated inflammatory conditions and pigmentary disorders. This review examines the most recent developments in the clinical application of Fernblock® and assesses how newly investigated action mechanisms may influence its clinical use.

Antioxidants (Basel) 2023; 12:antiox12040902. [PMID: 37107277 PMCID: PMC10135986 DOI: 10.3390/antiox12040902] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Accepted: 04/07/2023] [Indexed: 04/29/2023] Open
Abstract
Reactive oxygen species (ROS) promote oxidative stress, which directly causes molecular damage and disrupts cellular homeostasis, leading to skin aging. Baicalein, a flavonoid compound isolated from the root of Scutellaria baicalensis Georgi has antioxidant, anticancer, anti-inflammatory, and other medicinal properties. We aimed to investigate the protective effect of baicalein on the disruption of tight junctions and mitochondrial dysfunction caused by H2O2-induced oxidative stress in HaCaT keratinocytes. The cells were pretreated with 20 and 40 µM baicalein followed by treatment with 500 µM H2O2. The results revealed that baicalein exerted antioxidant effects by reducing intracellular ROS production. Baicalein attenuated the degradation of the ECM (MMP-1 and Col1A1) and the disruption of tight junctions (ZO-1, occludin, and claudin-4). In addition, baicalein prevented mitochondrial dysfunction (PGC-1α, PINK1, and Parkin) and restored mitochondrial respiration. Furthermore, baicalein regulated the expression of antioxidant enzymes, including NQO-1 and HO-1, via the Nrf2 signaling pathway. Our data suggest that the cytoprotective effects of baicalein against H2O2-induced oxidative stress may be mediated through the Nrf2/NQO-1/HO-1 signaling pathway. In conclusion, baicalein exerts potent antioxidant effects against H2O2-induced oxidative stress in HaCaT keratinocytes by maintaining mitochondrial homeostasis and cellular tight junctions.

Abstract
OBJECTIVE Long-term and high exposure to UV radiation can lead to the development of skin photoaging diseases. Therefore, there is an ongoing need for more natural and safe drugs to prevent or treat skin photoaging diseases. METHODS The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform database were used to collect the active compounds and corresponding targets of Cnidii Fructus, Arnebiae Radix, Angelicae Sinensis Radix, Poria, and Borneolum. The GeneCards database and the NCBI Gene database were used to collect the targets of skin photoaging diseases. The STRING database was used to construct a protein-protein interaction network formed by the intersecting targets of drugs and diseases. The Metascape database was applied for Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis of the targets. Molecular docking between active compounds and targets was verified by Autodock. After that, the skin photoaging model of mice was established and treated with MP gel. The skin characterization on the back of mice was observed, and the ameliorative effect of MP gel on skin photoaging was evaluated by histological and epidermal thickness assays. The MDA content and SOD activity were measured. Caspase-3 expression in mouse skin tissues was detected by immunohistochemistry, quantitative real-time polymerase chain reaction assay, and Western blot. RESULTS The results of network pharmacology experiments showed that the natural drugs have multi-component, multi-target therapeutic disease characteristics. The results of animal studies showed that MP gel improved the health of photoaged skin, promoted skin structural integrity, had antioxidant properties and significantly inhibited caspase-3 expression. CONCLUSION The experimental validation of the results of the preliminary network pharmacology analysis was carried out in animal experiments, which confirmed part of the mechanism of action of MP gel in the prevention and treatment of skin photoaging.

Chemical Profiling, Formulation Development, In Vitro Evaluation and Molecular Docking of Piper nigrum Seeds Extract Loaded Emulgel for Anti-Aging. Molecules 2022; 27:molecules27185990. [PMID: 36144719 PMCID: PMC9504714 DOI: 10.3390/molecules27185990] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2022] [Revised: 09/02/2022] [Accepted: 09/06/2022] [Indexed: 12/12/2022] Open
Abstract
Emulgel is a new innovatory technique for drug development permitting controlled release of active ingredients for topical administration. We report a stable emulgel of 4% Piper nigrum extract (PNE) prepared using 80% ethanol. The PNE-loaded formulation had an antioxidant activity of 84% and tyrosinase inhibition was 82%. Prepared formulation rendered spherical-shaped globules with high zeta potential (−45.5 mV) indicative of a stable system. Total phenolic contents were 58.01 mg GAE/g of dry extract whereas total flavonoid content was 52.63 mg QE/g of dry extract. Sun protection factor for PNE-loaded emulgel was 7.512 and formulation was stable without any evidence of physical and chemical changes following 90 days of storage. Gas chromatography-mass spectroscopy (GC-MS) revealed seventeen bioactive compounds in the PNE including monoterpenoids, triterpenoids, a tertiary alcohol, fatty acid esters, and phytosterols. In silico studies of GC-MS identified compounds show higher binding affinity in comparison to standard kojic acid indicating tyrosinase inhibition. It can be concluded that PNE-loaded emulgel had prominent antioxidant and tyrosinase inhibition and can be utilized as a promising topical system for anti-aging skin formulation.
