    Piceatannol is a naturally occurring hydroxylated resveratrol analogue that can be found in a variety of fruits and vegetables. It has been documented to have a wide range of beneficial effects, including anti-inflammatory, antioxidant, anti-aging, anti-allergic, antidiabetic, neuroprotective, cardioprotective, and chemopreventive properties. Piceatannol has significantly higher antioxidant activity than resveratrol. Piceatannol has been shown in preclinical studies to have the ability to inhibit or reduce the growth of cancers in various organs such as the brain, breast, lung, colon, cervical, liver, prostate, and skin. However, the bioavailability of Piceatannol is comparatively lower than resveratrol and other stilbenes. Several approaches have been reported in recent years to enhance its bioavailability and biological activity, and clinical trials are required to validate these findings. This review focuses on several aspects of natural stilbene Piceatannol, its chemistry, and its mechanism of action, and its promising therapeutic potential for the prevention and treatment of a wide variety of complex human diseases.

    Nutrients, 2023 Mar 23;15(7).
    PMID: 37049399 DOI: 10.3390/nu15071558
    As the global population ages, there is an increasing research on managing neurodegenerative diseases that mainly affect the elderly. Honey is one of the natural products and functional foods widely studied for its neuroprotective properties. This review investigates honey's effectiveness as a neuroprotective agent through in vitro, in vivo, and clinical research. The articles were browsed from three databases (PubMed, ScienceDirect, and Scopus) between the years of 2012 and 2022 using the keywords "honey" crossed with "neurodegenerative". Out of the 16 articles, six in vitro, eight in vivo, one combination study, and one clinical intervention were compiled. Among the various types of honey studied, the Tualang and Thyme honey exhibited the highest antioxidant, anti-inflammatory, and anticholinesterase activity, leading to the prevention and management of multiple neurodegenerative diseases such as Alzheimer's disease. The neuroprotective properties of honey are primarily attributed to its high polyphenol content, with quercetin and gallic acid being the most prominent. This review compiled considerable evidence of the anti-neurodegenerative properties of honey presented by in vitro and in vivo studies. However, more clinical intervention studies are required to support these findings further.

  3. Fulltext Polycystic ovary syndrome and its management: In view of oxidative stress
    Bhattacharya K, Dey R, Sen D, Paul N, Basak AK, Purkait MP, et al.
    Biomol Concepts, 2024 Jan 01;15(1).
    PMID: 38242137 DOI: 10.1515/bmc-2022-0038
    In the past two decades, oxidative stress (OS) has drawn a lot of interest due to the revelation that individuals with many persistent disorders including diabetes, polycystic ovarian syndrome (PCOS), cardiovascular, and other disorders often have aberrant oxidation statuses. OS has a close interplay with PCOS features such as insulin resistance, hyperandrogenism, and chronic inflammation; there is a belief that OS might contribute to the development of PCOS. PCOS is currently recognized as not only one of the most prevalent endocrine disorders but also a significant contributor to female infertility, affecting a considerable proportion of women globally. Therefore, the understanding of the relationship between OS and PCOS is crucial to the development of therapeutic and preventive strategies for PCOS. Moreover, the mechanistic study of intracellular reactive oxygen species/ reactive nitrogen species formation and its possible interaction with women's reproductive health is required, which includes complex enzymatic and non-enzymatic antioxidant systems. Apart from that, our current review includes possible regulation of the pathogenesis of OS. A change in lifestyle, including physical activity, various supplements that boost antioxidant levels, particularly vitamins, and the usage of medicinal herbs, is thought to be the best way to combat this occurrence of OS and improve the pathophysiologic conditions associated with PCOS.

    J Oral Biosci, 2021 06;63(2):97-103.
    PMID: 33864905 DOI: 10.1016/j.job.2021.04.001
    BACKGROUND: Periodontitis is a noncommunicable inflammatory disease of the soft tissue and bone surrounding the teeth in the jaw, which affects susceptible individuals with poor oral hygiene. A growing interest has been seen in the use of dietary supplements and natural products for the treatment and prevention of periodontitis. Vitamin E consists of two major groups, namely tocopherols and tocotrienols, which are botanical lipophilic compounds with excellent anti-inflammatory and antioxidant properties.

    HIGHLIGHT: This review aimed to summarize the preclinical and clinical findings on the effects of vitamin E on periodontitis. The current literature suggests that vitamin E could improve the periodontal status by correcting redox status imbalance, reducing inflammatory responses, and promoting wound healing, thus highlighting the potential of vitamin E in the management of periodontitis.

    CONCLUSION: Direct evidence for the use of vitamin E supplementation or treatment of periodontitis in humans is still limited. More well-designed and controlled studies are required to ascertain its effectiveness.

    A novel coronavirus disease (COVID-19) or severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2), transmitted from person to person, has quickly emerged as the pandemic responsible for the current global health crisis. This infection has been declared a global pandemic, resulting in a concerning number of deaths as well as complications post-infection, primarily among vulnerable groups particularly older people and those with multiple comorbidities. In this article, we review the most recent research on the role of date palm (Phoenix dactylifera L.) fruits (DPFs) to prevent or treat COVID-19 infection. The mechanisms underlying this preventive or therapeutic effect are also discussed in terms of bioactivity potentials in date palm, e.g., antimicrobial, antioxidant, anticancer, anti-diabetic, anti-inflammatory, neuroprotective, and hemolytic potential, as well as prospect against COVID-19 disease and the potential product development. Therefore, it can be concluded that regular consumption of DPFs may be associated with a lower risk of some chronic diseases. Indeed, DPFs have been widely used in folk medicine since ancient times to treat a variety of health conditions, demonstrating the importance of DPFs as a nutraceutical and source of functional nourishment. This comprehensive review aims to summarize the majority of the research on DPFs in terms of nutrient content and biologically active components such as phenolic compounds, with an emphasis on their roles in improving overall health as well as the potential product development to ensure consumers' satisfaction in a current pandemic situation. In conclusion, DPFs can be given to COVID-19 patients as a safe and effective add-on medication or supplement in addition to routine treatments.

    A spinal cord injury (SCI) occurs when the spinal cord is deteriorated or traumatized, leading to motor and sensory functions lost even totally or partially. An imbalance within the generation of reactive oxygen species and antioxidant defense levels results in oxidative stress (OS) and neuroinflammation. After SCI, OS and occurring pathways of inflammations are significant strenuous drivers of cross-linked dysregulated pathways. It emphasizes the significance of multitarget therapy in combating SCI consequences. Polyphenols, which are secondary metabolites originating from plants, have the promise to be used as alternative therapeutic agents to treat SCI. Secondary metabolites have activity on neuroinflammatory, neuronal OS, and extrinsic axonal dysregulated pathways during the early stages of SCI. Experimental and clinical investigations have noted the possible importance of phenolic compounds as important phytochemicals in moderating upstream dysregulated OS/inflammatory signaling mediators and axonal regeneration's extrinsic pathways after the SCI probable significance of phenolic compounds as important phytochemicals in mediating upstream dysregulated OS/inflammatory signaling mediators. Furthermore, combining polyphenols could be a way to lessen the effects of SCI.

  10. [The roots of Cha and Gambir]
    Sugiyama S
    Yakushigaku Zasshi, 2005;40(2):98-106.
    PMID: 17152831
    This article attempts to trace the origin of tea. The author believes the ancient Chinese tea, "chia", is either Jicha (water extract from the pith of Acacia catechu that grows naturally in the mountainous border between the Yunnan province of China and southern Asian countries) or Jicha-Kagikazura (water extract from the young branches and leaves of Uncaris gambir, originally found in India/Sri Lanka). Both were pulverized after being kiln-dried and then mixed with water to produce a thick suspension, or tea. Although the drink is bitter and has an astringent property, it has a particular flavor with a refreshing after-taste. Its components with medicinal properties include tannin, catechin, and various flavonoids, making us believe it was worthwhile for the people at the time to consume the drink regularly. Generally speaking, tea cultivation in China flourished south of the Yangzi Jiang River including the present Zhejiang and Anhui provinces. Depending on the regions, there were words for tea in various languages, including the names of places where particular teas were grown. In addition to the names that appear in the famous Chajing book, it is interesting to note Da Fang pronounced tea as "TAH". Because the area south of the Yangzi Jiang has traditionally been active in foreign trade since the ancient and middle ages. People in this region consumed various foreign originated teas as well. This included Gambir, which was introduced to southern Asia (including present Malaysia and Indonesia) and was consumed as an herbal tea under names such as Guo Luo or Ju Luo teas. Paan, from India, also uses Gambir paste and was a popular chewing refreshment to prevent diseases caused by miasma as well as to keep one's mouth clean. The name A-sen-yaku used in Japan was taken from the plant name Acasia, and Gambir was used to dye Buddhist monks' Ke-Ra bags to a blackish yellow color. The Daikanwa dictionary states the Ra in the name, which means thin silk, was later replaced with "A". The official name for Ji-cha [Er Cha] in modern China is "Gaiji-cha", [Hal-Er Cha], which comes from the name of a variety of tea made by the Ai-Ni tribal subgroup of the ethnic Ha-Ni in Yunnan province. The [see character in text] character is pronounced "ni", which is a homophony of [character in text]. Based on these facts, "Ai-Ni" should be considered the same as "Hai-Ni". Because the ethnic groups in Yunnan province used primitive and tough tea leaves, which were eaten instead of being infused in water, the leaves were first fermented by being buried in the ground. Even today, people of these ethnic groups prefer fungus-fermented black tea with a particular flavor. In contrast, the ethnic Hans used and still use improved and softer young shoots of tea leaves to prepare mainly green tea. It has recently been discovered that Acapsia, as well as Gambir, has anti-oxidant properties, and that consumption over time is effective against many lifestyle-related adult diseases. It may be well worthwhile to cast fresh light upon ancient tea drinking customs.

  12. In Vitro Antioxidation, Antihepatic Steatosis, and Anti-Inflammatory Effects of Ethyl Acetate Fraction from Auricularia nigricans (Agaricomycetes)
    Teoh HL, Aminudin N, Abdullah N
    Int J Med Mushrooms, 2021;23(2):43-56.
    PMID: 33639080 DOI: 10.1615/IntJMedMushrooms.2021037649
    Nonalcoholic fatty liver disease (NAFLD) is currently one of the most common liver diseases worldwide. Lifestyle modifications through the diet are the mainstay of treatment. Auricularia nigricans is a popular edible mushroom known to possess medicinal properties. Gas chromatography-mass spectrometry and liquid chromatography-tandem mass spectrometry analysis indicated that linoleic acid ethyl ester, butyl 9,12-octadecadienoate, 9,12-octadecadienoic acid, ergosta-5,7,22-trien-3-ol, 2(3,4-dihydroxyphenyl)-7-hydroxy-5-benzene propanoic acid, and 3,30-di-0-methyl ellagic acid were present in the A. nigricans ethyl acetate (EA) fraction. The cytotoxicity assay showed that the EA fraction was noncytotoxic to HepG2 cells at concentrations < 100 μg/mL. In the antihepatic steatosis assay, 50 μg/mL of EA fraction caused a decline in absorbance to 0.20 ± 0.02 compared to palmitic acid (PA)-induced cells (0.24 ± 0.02). Furthermore, cells treated with 50 μg/mL and 25 μg/mL of EA fraction contributed an approximately 1.12-fold and 1.08-fold decrease in lipid accumulation compared to PA-induced cells. Coincubation with PA and 25 μg/mL of EA fraction decreased levels of tumor necrosis factor-α, interleukin (IL)-6, IL-8, and monocyte chemoattractant protein-1 to 140.48 ± 8.12, 91.16 ± 2.40, 184.00 ± 22.68, and 935.88 ± 39.36 pg/mL compared to PA-induced cells. The presence of the EA fraction also suppressed the stress-activated protein kinase/Jun amino-terminal kinase, p-38 mitogen-activated protein kinase, nuclear factor-κB, and signal transducer and activator of transcription 3 signaling pathways. In conclusion, these findings suggest that the A. nigricans EA fraction demonstrates antisteatotic effects involving antioxidant capacity, hypolipidemic effects, and anti-inflammatory capacity in the PA-induced NAFLD pathological cell model.

    Shaikh SA, Varatharajan R, Muthuraman A
    Int J Mol Sci, 2022 Nov 04;23(21).
    PMID: 36362316 DOI: 10.3390/ijms232113531
    Vascular dementia (VaD) is a serious global health issue and type 2 diabetes mellitus (T2DM) patients are at higher risk. Palm oil tocotrienol-rich fraction (TRF) exhibits neuroprotective properties; however, its effect on VaD is not reported. Hence, we evaluated TRF effectiveness in T2DM-induced VaD rats. Rats were given a single dose of streptozotocin (STZ) and nicotinamide (NA) to develop T2DM. Seven days later, diabetic rats were given TRF doses of 30, 60, and 120 mg/kg orally for 21 days. The Morris water maze (MWM) test was performed for memory assessment. Biochemical parameters such as blood glucose, plasma homocysteine (HCY) level, acetylcholinesterase (AChE) activity, reduced glutathione (GSH), superoxide dismutase (SOD) level, and histopathological changes in brain hippocampus and immunohistochemistry for platelet-derived growth factor-C (PDGF-C) expression were evaluated. VaD rats had significantly reduced memory, higher plasma HCY, increased AChE activity, and decreased GSH and SOD levels. However, treatment with TRF significantly attenuated the biochemical parameters and prevented memory loss. Moreover, histopathological changes were attenuated and there was increased PDGF-C expression in the hippocampus of VaD rats treated with TRF, indicating neuroprotective action. In conclusion, this research paves the way for future studies and benefits in understanding the potential effects of TRF in VaD rats.

    Azlina MFN, Qodriyah MS, Kamisah Y
    Curr Drug Targets, 2018;19(12):1456-1462.
    PMID: 29173163 DOI: 10.2174/1389450118666171122130338
    BACKGROUND: Scientific reports had shown that stress is related to numerous pathological changes in the body. These pathological changes can bring about numerous diseases and can significantly cause negative effects in an individual. These include gastric ulcer, liver pathology and neurobehavioral changes. A common pathogenesis in many diseases related to stress involves oxidative damage. Therefore, the administration of antioxidants such as vitamin E is a reasonable therapeutic approach. However, there is conflicting evidence about antioxidant supplementation.

    OBJECTIVE: The aim of this work was to summarize documented reports on the effects of tocopherol and tocotrienol on various pathological changes induced by stress.

    RESULTS AND CONCLUSION: This review will reveal the scientific evidence of enteral supplementation of vitamin E in the forms of tocotrienol and tocopherol in animal models of stress. These models mimic the stress endured by critically ill patients in a clinical setting and psychological stress in individuals. Positive outcomes from enteral feeding of vitamin E in reducing the occurrence of stress-induced pathological changes are discussed in this review. These positive findings include their ability to reduced stress-induced gastric ulcers, elevated liver enzymes and improved locomotors activity. Evidences showing tocotrienol and tocopherol effects are not just related to its ability to reduce oxidative stress but also acting on other mechanism, are discussed.

  15. Role of Flavonoids in Management of Various Biological Targets in Alzheimer's Disease: Evidence from Preclinical to Clinical Studies
    Alharbi KS, Javed Shaikh MA, Imam SS, Alshehri S, Ghoneim MM, Almalki WH, et al.
    Curr Med Chem, 2023;30(18):2061-2074.
    PMID: 36415096 DOI: 10.2174/0929867330666221122115212
    More than 10 million people worldwide have Alzheimer's disease (AD), a degenerative neurological illness and the most prevalent form of dementia. AD's progression in memory loss, cognitive deterioration, and behavioral changes are all symptoms. Amyloid-beta 42 (Aβ42), the hyperphosphorylated forms of microtubule-associated tau protein, and other cellular and systemic alterations are all factors that contribute to cognitive decline in AD. Rather than delivering a possible cure, present therapy strategies focus on reducing disease symptoms. It has long been suggested that various naturally occurring small molecules (plant extract products and microbiological isolates, for example) could be beneficial in preventing or treating disease. Small compounds, such as flavonoids, have attracted much interest recently due to their potential to alleviate cellular stress. Flavonoids have been proven helpful in various ways, including antioxidants, anti-inflammatory agents, and anti-apoptotic agents, but their mechanism remains unknown. The flavonoid therapy of Alzheimer's disease focuses on this review, which includes a comprehensive literature analysis.

    PMID: 37049991 DOI: 10.3390/molecules28073228
    Breast cancer is among the most recurrent malignancies, and its prevalence is rising. With only a few treatment options available, there is an immediate need to search for better alternatives. In this regard, nanotechnology has been applied to develop potential chemotherapeutic techniques, particularly for cancer therapy. Specifically, albumin-based nanoparticles are a developing platform for the administration of diverse chemotherapy drugs owing to their biocompatibility and non-toxicity. Visnagin, a naturally derived furanochromone, treats cancers, epilepsy, angina, coughs, and inflammatory illnesses. In the current study, the synthesis and characterization of albumin visnagin (AV) nanoparticles (NPs) using a variety of techniques such as transmission electron microscopy, UV-visible, Fourier transform infrared, energy dispersive X-ray composition analysis, field emission scanning electron microscopy, photoluminescence, X-Ray diffraction, and dynamic light scattering analyses have been carried out. The MTT test, dual AO/EB, DCFH-DA, Annexin-V-FITC/PI, Propidium iodide staining techniques as well as analysis of apoptotic proteins, antioxidant enzymes, and PI3K/Akt/mTOR signaling analysis was performed to examine the NPs' efficacy to suppress MDA-MB-468 cell lines. The NPs decreased cell viability increased the amount of ROS in the cells, disrupted membrane integrity, decreased the level of antioxidant enzymes, induced cell cycle arrest, and activated the PI3K/Akt/mTOR signaling cascade, ultimately leading to cell death. Thus, AV NPs possesses huge potential to be employed as a strong anticancer therapy alternative.

    PMID: 38432575 DOI: 10.1016/j.exger.2024.112389
    Aging-related diseases (ARDs) are a major global health concern, and the development of effective therapies is urgently needed. Kaempferol, a flavonoid found in several plants, has emerged as a promising candidate for ameliorating ARDs. This comprehensive review examines Kaempferol's chemical properties, safety profile, and pharmacokinetics, and highlights its potential therapeutic utility against ARDs. Kaempferol's therapeutic potential is underpinned by its distinctive chemical structure, which confers antioxidative and anti-inflammatory properties. Kaempferol counteracts reactive oxygen species (ROS) and modulates crucial cellular pathways, thereby combating oxidative stress and inflammation, hallmarks of ARDs. Kaempferol's low toxicity and wide safety margins, as demonstrated by preclinical and clinical studies, further substantiate its therapeutic potential. Compelling evidence supports Kaempferol's substantial potential in addressing ARDs through several mechanisms, notably anti-inflammatory, antioxidant, and anti-apoptotic actions. Kaempferol exhibits a versatile neuroprotective effect by modulating various proinflammatory signaling pathways, including NF-kB, p38MAPK, AKT, and the β-catenin cascade. Additionally, it hinders the formation and aggregation of beta-amyloid protein and regulates brain-derived neurotrophic factors. In terms of its anticancer potential, kaempferol acts through diverse pathways, inducing apoptosis, arresting the cell cycle at the G2/M phase, suppressing epithelial-mesenchymal transition (EMT)-related markers, and affecting the phosphoinositide 3-kinase/protein kinase B signaling pathways. Subsequent studies should focus on refining dosage regimens, exploring innovative delivery systems, and conducting comprehensive clinical trials to translate these findings into effective therapeutic applications.

    Jaganathan SK, Balaji A, Vellayappan MV, Asokan MK, Subramanian AP, John AA, et al.
    Anticancer Agents Med Chem, 2015;15(1):48-56.
    PMID: 25052987
    Recent statistics revealed that cancer is one among the main reasons for death throughout the world. Several treatments are available but still there is no cure when it is detected at late stages. One of the treatment modes for cancer is chemotherapy which utilizes anticancer drugs in order to eradicate the cancer cells by apoptosis. Apoptosis is a programmed cell death through which body maintains homeostasis or kills cancer cells by utilizing its cell machinery. Recent researches have concluded that dietary agents have a putative role in instituting apoptosis of cancer cells. Honey, one of the victuals rich in antioxidants, has a long-standing exposure to humans and its role in cancer prevention and treatment is a topic of current interest. Various researchers have been experimenting honey against different cancers and provided valuable insights about the apoptosis induced by the honey. This review will highlight the recent findings of apoptotic mechanism involved in different cancer cells. Further it also reports antitumor activity of honey in some animal models. Hence it is high-time to initiate more preclinical trials as well as clinical experiments which would further add to the knowledge of anticancer nature of honey and also endorse honey as a potential candidate in the war against cancer.

  19. Fulltext Biomedical properties of a natural dietary plant metabolite, zerumbone, in cancer therapy and chemoprevention trials
    Rahman HS, Rasedee A, Yeap SK, Othman HH, Chartrand MS, Namvar F, et al.
    Biomed Res Int, 2014;2014:920742.
    PMID: 25025076 DOI: 10.1155/2014/920742
    Zerumbone (ZER) is a naturally occurring dietary compound, present in many natural foods consumed today. The compound derived from several plant species of the Zingiberaceae family that has been found to possess multiple biomedical properties, such as antiproliferative, antioxidant, anti-inflammatory, and anticancer activities. However, evidence of efficacy is sparse, pointing to the need for a more systematic review for assessing scientific evidence to support therapeutic claims made for ZER and to identify future research needs. This review provides an updated overview of in vitro and in vivo investigations of ZER, its cancer chemopreventive properties, and mechanisms of action. Therapeutic effects of ZER were found to be scientifically plausible and could be explained partially by in vivo and in vitro pharmacological activities. Much of the research outlined in this paper will serve as a foundation to explain ZER anticancer bioactivity, which will open the door for the development of strategies in the treatment of malignancies using ZER.

    Khor SC, Abdul Karim N, Ngah WZ, Yusof YA, Makpol S
    Oxid Med Cell Longev, 2014;2014:914853.
    PMID: 25097722 DOI: 10.1155/2014/914853
    Sarcopenia is a geriatric syndrome that is characterized by gradual loss of muscle mass and strength with increasing age. Although the underlying mechanism is still unknown, the contribution of increased oxidative stress in advanced age has been recognized as one of the risk factors of sarcopenia. Thus, eliminating reactive oxygen species (ROS) can be a strategy to combat sarcopenia. In this review, we discuss the potential role of vitamin E in the prevention and treatment of sarcopenia. Vitamin E is a lipid soluble vitamin, with potent antioxidant properties and current evidence suggesting a role in the modulation of signaling pathways. Previous studies have shown its possible beneficial effects on aging and age-related diseases. Although there are evidences suggesting an association between vitamin E and muscle health, they are still inconclusive compared to other more extensively studied chronic diseases such as neurodegenerative diseases and cardiovascular diseases. Therefore, we reviewed the role of vitamin E and its potential protective mechanisms on muscle health based on previous and current in vitro and in vivo studies.
