As shown in Fig. Direct anti-oxidant activity of polyphenols: hydrogen abstraction, quenching of ROS and formation of stabilised stilbenoid a and flavonoid b radicals. Resveratrol is arguably the most widely studied polyphenol in ageing science [ 9 ]. Resveratrol itself entries 1a, 2a, 3b and 4g, Fig.

By contrast, fully substituted derivatives 1g—1jlacking critical hydroxyl groups, show greatly diminished or zero antioxidant capabilities [ 27 ].

Resveratrol and stilbenoid derivatives. Note resveratrol was studied in all four groups and is shown as entries 1a, 2a, 3b and 4g for comparison. TEMP- 1 O 2 —singlet oxygen quenching. DPPH -DPPH nitrogen radical scavenging assay.

General schemes or scaffolds are enclosed in dotted lines. The E -olefin functionality in resveratrol is important for potent radical scavenging activity since dihydro-resveratrol 1kwhich lacks the trans-olefin double bond, was shown to have fivefold less potent direct antioxidant activity than resveratrol 1adue to diminished ability to stabilise the radical via delocalisation determined in a DPPH radical scavenging assay [ 2829 ].

Furthermore, an alkynyl analogue of resveratrol 1l was found to be a less potent antioxidant than resveratrol 1a in a cell based model of oxidative stress [ 30 ], indicating requirement for the trans-olefin in resveratrol for potent antioxidant activity.

Given the critical role of a hydroxyl moiety in the formation of a stable stilbenoid radical Fig. In a series of six stilbenoids Fig. However entries 2b and 2d showed greatly improved activity, probably due to the relative substitution patterns, i.

Twenty-five hydroxylated and methoxylated IRAs [ 32 ] were analysed for their ability to quench DPPH radicals and singlet oxygen. Structures 3c—3i, all possessing an ortho-hydroxyl group, were the most potent derivatives in terms of anti-oxidant activity in the DPPH radical scavenging assay EC 50 10—30 µM [ 32 ]; the proximity of the imine nitrogen may permit stabilisation of the electron-deficient oxygen radical through donation [ 33 ].

Additionally, derivatives in the IRA series were more able to quench singlet oxygen than the parent resveratrol 3b determined via TEMP- 1 O 2 adduct formation assay.

Imine resveratrol analogues have been investigated in several other independent studies and have shown similar activities and SAR trends [ 35 ]. Furthermore the methoxylated IRA 3i demonstrated anti-inflammatory activity in an in vivo mouse model [ 36 ].

These data demonstrate that either olefins or imines in the stilbenoid scaffold can support antioxidant activity, and further emphasise the importance of hydroxyl groups in radical formation and stabilisation.

Extensive structural modifications to the stilbenoid scaffold are permitted whilst still retaining or even enhancing antioxidant activity, provided that the key structural features required for activity are retained. Several tetrahydropyrroyl- THP derivatives 4b were analysed alongside their stilbenoids counterparts 4a for their ability to block DNA oxidation in a thiobarbituric acid assay [ 3738 ].

All THP derivatives were found to be more potent antioxidants than their stilbenoid counterparts. With regards to substituent effects, 2-hydroxy phenyl 4h was the most potent antioxidant, followed by para 4j then meta 4i.

Derivatives containing electron donating groups such as 3-methoxy 4k possessed stronger antioxidant capacity, potentially permitting stabilisation of the radical intermediates. The most potent antioxidant was synthesized through tetrahydropyrrollidisation of resveratrol 4g itself, to yield 4lthough no other tri-hydroxylated THP derivatives were studied.

The function of the THP group as a chemical bystander was also investigated; it was found that oxidation of the tetrahydropyrrole to the pyrrole 4m occurs in situ, indicating that the THP group itself is stoichiometrically antioxidant, and increases activity in a mechanistic manner as opposed to just altering the stability of the phenoxy radicals.

The antioxidant capabilities of flavonoids follow similar trends to the stilbenoids but are more nuanced, due to the different effects of flavonoid core scaffolds, as illustrated in Fig.

In vitro assay outcomes in which these chemical series are described are given below where these have been reported in the primary papers see text for details.

Additionally, ether groups in the scaffold help to stabilise the cation free radical through resonance. The flavonol scaffold 5d possesses all of these faculties and indeed is experimentally found to be one of the most potent antioxidant structures in the flavonoid class; stepwise masking of these features serves to diminish activity.

The scaffold, 5dFig. As observed in the stilbenoids, the presence of OH groups were required for radical scavenging. Importantly, quercetin in combination with kinase inhibitor dasatinib is proving of clinical value in diseases such as idiopathic lung fibrosis and diabetic kidney disease [ 4344 ].

While benefit has been attributed to senolytic activity selective killing of senescent cellsantioxidant activity of quercetin in this context may also be important, possibly by preventing further ROS-induced senescence. For both the stilbenoid and flavonoid scaffolds, there are several instances where compounds containing catechol ortho-dihydroxyl functionality possess more potent radical scavenging activity than would otherwise be expected from two non-contiguous hydroxyl group based on the SAR, e.

This effect is due to neighbouring group participation in hydrogen bonding and in stabilisation of the resultant radical [ 3445 ]. SAR investigations towards optimisation of radical scavenging ability i. in vitro efficacy still present only a part of a successful medicinal chemistry campaign—the molecules must also be appropriately absorbed and delivered to their sub-cellular site of action in the body, so improvement of the ADME profile of the molecules is an important consideration in delivering effective therapeutics.

While the 7-OH 10f substitution increased activity in scavenging peroxyl radicals ORAC6-OH and 8-OH quinolones 10d and 10g showed increased scavenging activity towards hydroxyl radicals as well as ferrous iron reduction TBARS and FRAP assays, respectively.

Iron levels increase up to fold in pro-inflammatory senescent cells which also show high endogenous ROS levels [ 47 ], so it will be interesting to test whether iron reduction by quinolones is biologically relevant in age-related diseases where senescence is causative.

The quinolones were generally more potent than their flavone counterparts, with the exception of 6-hydroxyflavone vs. Based on electron spin resonance ESR analysis of flavonoid antioxidant activities in terms of number and position of OH groups, it has been suggested that rate of reaction rather than stoichiometry may be important for biological protection against ROS [ 48 ].

Physiological responses to oxidative stress are co-ordinated within cells by the transcription factor NRF2 Nuclear factor erythroid 2-related factor 2. Under normoxic conditions, NRF2 levels are low, predominantly due to binding to the negative regulator KEAP1 Kelch-like ECH-associated protein 1 which facilitates NRF2 ubiquitination and proteasomal degradation [ 4950 ].

During increased oxidative stress, oxidative cysteine modification of KEAP1 alters its conformation, resulting in diminished binding to NRF2 [ 51 ]. NRF2, no longer subject to degradation, translocates to the nucleus where it binds to the antioxidant response element ARE upstream of cytoprotective genes, e.

NAD P H quinone oxidoreductase 1 NQO1glutathione S-transferase GSTand glutathione reductase [ 5253 ], inducing their expression. These factors act to lower ROS and oxidative stress, while simultaneously reducing the cysteines in KEAP1 and subsequently re-establishing a baseline equilibrium of NRF2 activity.

Activation of NRF2 signalling, and concomitant amelioration of age-related phenotypes by polyphenols is well documented in vitro and in vivo, and the scaffolds serve as valuable starting points for SAR investigations [ 545556575859 ].

The stilbenoids resveratrol and pterostilbene specifically have both been demonstrated to upregulate NRF2 activity [ 5560 ]. As well co-ordinating the antioxidant response, activation of NRF2 has been demonstrated to increase proteasomal activity, allowing cells to control protein levels by regulated degradation; while the proteasome degrades proteins tagged with ubiquitin, larger scale protein and organelle regulation within cells is mediated by autophagy.

The importance of proteostasis is highlighted by the finding of downregulation of autophagy and proteasomal activity in replicatively senescent cells in vitro [ 61 ], while inhibition of the proteasome in replicating cells to levels commensurate with that seen in senescence is sufficient to induce premature cellular senescence [ 6263 ].

Activation of NRF2 using small molecules such as 3 H -1,2-dithiolethione D3T, 11 and 18α-Glycyrrhetinic acid 18α-GA, 12 increases the expression and activity of the proteasome in a NRF2-dependant manner [ 6465 ].

Activation of NRF2 by 18α-GA confers resistance against oxidative stress, extends the maximal replicative capacity of human lung HFL-1 fibroblasts, and delays the onset of several phenotypes of cellular senescence [ 65 ].

Activation of SKN-1 worm orthologue of human NRF2 was also demonstrated to upregulate proteasome activity and extend life span in C. elegans [ 66 ]. Many compounds that upregulate the antioxidant response in vivo contain thiol reactive functionality, for example α, β-unsaturated carbonyl groups, that can undergo conjugate addition reactions to covalently bind to their targets.

Examples include chalcones and various flavonoids [ 6768 ]. NRF2 can also be modulated through imine resveratrol analogues with varied substitution patterns of hydroxylation and methoxylation [ 70 ].

By combining structural features from promising analogues, two second round derivatives, 13g and 13hwere designed which proved to be the most potent derivatives synthesized, increasing ARE-luciferase levels by approximately and fold over control at 15 µM respectively c.

resveratrol 13i leads to a threefold induction at 15 µM. The mechanism of action is proposed to be a covalent inhibition of KEAP1 through nucleophilic addition of a cysteine moiety from KEAP into the electrophilic imine. This interaction could be potentially stabilised through interaction with the OH increasing the reactivity of the incoming thiol, which is illustrated in entry 13j.

The fact that ortho-hydroxyl groups adjacent to electrophilic sites have been shown elsewhere [ 7172 ] to increase the rate of reactivity with sulfhydryl moieties supports this hypothesis.

IRAs represent a promising series since they demonstrate both direct and indirect radical scavenging capacity and are active in vivo [ 36 ].

Lastly, let's not forget about stilbenes, a group of polyphenols found in red wine and grapes. Resveratrol, a well-known stilbene, has gained attention for its potential anti-aging effects. It has been shown to activate longevity genes and enhance cellular function, leading to improved overall health and increased lifespan. Now that we understand the different types of polyphenols and their benefits, it's time to explore how we can incorporate them into our diet. Luckily, there are plenty of delicious and nutritious sources of polyphenols to choose from. Fruits like berries, citrus fruits, and apples are rich in flavonoids, while vegetables like broccoli, spinach, and kale are also excellent sources. Whole grains, legumes, nuts, and seeds are additional plant-based foods that can provide a significant amount of polyphenols. So, go ahead and load up your plate with a colorful variety of plant-based foods to reap the rewards of polyphenols! By incorporating these mighty compounds into your diet, you can enhance your body's antioxidant defenses, reduce inflammation, and potentially lower your risk of chronic diseases. Embrace the power of polyphenols and let them work their magic in promoting your health and well-being. Now that we know what polyphenols are, let's delve into the fascinating ways in which they can slow down the aging process. But first, let's take a closer look at the role of polyphenols in cellular health. Our cells are the building blocks of our bodies, and the health of our cells directly impacts our overall well-being. Polyphenols have been found to support cellular health by protecting against oxidative stress, a process that can damage our cells and contribute to aging. Oxidative stress occurs when the balance between free radicals and antioxidants in our body is disrupted. Free radicals are unstable molecules that can damage our cells, leading to aging and age-related diseases. But fear not, because polyphenols, with their antioxidative powers, can help restore this balance and prevent premature aging. In addition to their role in combating oxidative stress, polyphenols also play a crucial role in reducing inflammation. Inflammation is the body's natural response to injury or infection, and chronic inflammation has been linked to various diseases, including aging. However, polyphenols have been found to possess potent anti-inflammatory properties, helping to reduce inflammation and slow down the aging process. But how exactly do polyphenols achieve these remarkable effects? Well, it turns out that polyphenols have the ability to regulate gene expression, meaning they can influence which genes are turned on or off. By doing so, polyphenols can activate genes that promote cellular health and longevity while inhibiting genes that contribute to aging. Furthermore, polyphenols can also stimulate the production of proteins that are involved in repairing DNA damage. As we age, our DNA becomes more susceptible to damage, which can lead to accelerated aging. However, polyphenols can help counteract this by enhancing DNA repair mechanisms, ensuring that our cells stay healthy and youthful. Another fascinating aspect of polyphenols is their ability to promote the production of collagen, a protein that plays a crucial role in maintaining the elasticity and firmness of our skin. As we age, collagen production naturally declines, leading to wrinkles and sagging skin. However, polyphenols can help boost collagen synthesis, keeping our skin looking youthful and vibrant. It's important to note that polyphenols are not a magical cure for aging, but rather a powerful tool that can complement a healthy lifestyle. Eating a diet rich in fruits, vegetables, and other plant-based foods can provide a wide variety of polyphenols, ensuring that you reap their full anti-aging benefits. In conclusion, polyphenols are truly remarkable compounds that have the potential to slow down the aging process. From protecting against oxidative stress and reducing inflammation to regulating gene expression and promoting collagen production, polyphenols offer a multitude of benefits for our cellular health and overall well-being. Curious to know what the research says about polyphenols and their anti-aging potential? Let's take a look! Polyphenols, a diverse group of naturally occurring compounds found in plant-based foods, have gained significant attention in recent years due to their potential health benefits. Numerous studies have explored the effects of polyphenols on aging and have uncovered some promising findings. Several studies have highlighted the promising effects of polyphenols on aging. For instance, a study published in the Journal of Nutrition found that a diet rich in polyphenols was associated with a lower risk of cardiovascular disease, a common age-related condition. The researchers observed that individuals who consumed higher amounts of polyphenol-rich foods, such as berries, citrus fruits, and green tea, had a reduced risk of developing cardiovascular issues compared to those with a lower intake. Another study in the Journal of Agricultural and Food Chemistry showed that the consumption of polyphenol-rich foods was linked to improved cognitive function in older adults. The researchers observed that individuals who regularly consumed foods rich in polyphenols, such as dark chocolate, nuts, and red wine, experienced better memory, attention, and overall cognitive performance compared to those who had a lower intake of these foods. com", "practicelabel": "McKinney, TX", "skinType": "", "mdName": "Jonathan Richey, DO, MHA", "mdTitle": "STS Approved Doctor", "practiceDesc": "Whether your dermatology concern is health-related or cosmetic, Dr. Jonathan Richey and his team of dermatology fellowship trained physician assistants recognize the importance of healthy skin, hair and nails, and pride themselves on providing high-quality dermatology care in North Texas.

Polyphenols and skin aging -

Are Polyphenols For Skin Anti-Aging? In Body , Skin. By By Dr. Michelle Jeffries, D. What are polyphenols? What are the benefits of polyphenols for skin?

Benefits of polyphenols for skin include: A boost in mitochondrial function. Polyphenols act as regulators of mitochondrial processes.

Healthy mitochondrial function reduces oxidative stress, a link to photoaging and the signs of premature aging. Reduced hyperpigmentation.

Polyphenols from sources like pomegranate extract may stimulate collagen production responsible for new skin cell growth.

This is important to reducing pigmentation caused by harmful UV rays. Improved elasticity. Our skin loses some elasticity as we age, causing sagging and wrinkles.

Polyphenols increase both elastin and collagen lost in the aging process. Increased collagen synthesis. Collagen is made up of protein enzymes responsible for new skin cell growth. As we age, collagen declines, and the skin loses some of those protective effects. Polyphenols boost collagen production.

Anti-inflammation effects. They reduce skin conditions caused by inflammation, such as acne and dermatitis. Sunburn reduction. Polyphenols decrease the effects of harmful ultraviolet A UVA and ultraviolet B UVB radiation.

Researchers are even looking for a positive link between sunburn prevention and orally ingested polyphenol sources. Improved hydration. Skin treated with topical polyphenols boasts a higher moisture content.

Dehydrated skin is dull, uneven, and even wrinkled, accelerating aging. Getting More Polyphenols In Your Diet Polyphenols are rich in antioxidant properties that do more for you than fight back against premature aging.

High-polyphenol foods include: Blueberries Grapes Cranberries Apples Plums Nuts chestnut and hazelnut in particular Black and white beans Pomegranate juice Chicory Red onions Spinach Virgin olive oil Cloves Turmeric Dark chocolate and cocoa powder Flaxseed Green tea Green tea deserves a special mention as a great addition to overall skin health.

Polyphenols are unique chemical compounds found only in plants. While these micronutrients are not necessarily considered antioxidants, they act similarly by neutralizing free radicals — harmful chemical and environmental compounds that damage our skin.

Polyphenols are packed with an abundance of benefits, in addition to their protective and anti-aging properties. Eating polyphenol-rich foods can help defend your bodily systems against free radical damage, thus lowering your risk for illnesses.

Polyphenols are found only in plants. They play a crucial role in plant growth, by protecting fruits and vegetables from the harsh sunlight as they reach maturity. You can ensure an increase in polyphenols in your diet simply by eating more leafy greens and fiber-rich fruits, although some foods contain more polyphenols than others.

The following foods are especially high in beneficial polyphenols:. Dark chocolate has long been purported as an excellent source of antioxidants, and it does indeed feature polyphenols as a star ingredient.

While milk chocolate is little more than a tasty indulgence, the higher percentage of cacao found in dark bitter chocolate allows this grown-up dessert to help keep your weight regulated and your skin youthful. While all berries contain impressive levels of polyphenols, blueberries are said to contain the highest concentrations.

Moreover, blueberries are high in vitamin C, vitamin K, and manganese, earning its title as a true superfood. Believe it or not, cloves are actually the plants which contain the highest concentration of polyphenols! Cloves are deliciously spicy and nutty when cooked whole, which is the best way to maximize your polyphenol intake when eating them.

Green tea contains a wide variety of specific polyphenols, especially epigallocatechin gallate eppo-gallih-cat-ickan gal-lit — commonly known as EGCG. This superstar polyphenol is known for its anti-inflammatory benefits, as well as a capacity to help with weight management.

In addition to its numerous other polyphenols, flavonoids and tannins, green tea is an extremely beneficial beverage for a healthier lifestyle.

The skins of red wine grapes contain a high concentration of resveratrol which is, you guessed it: a polyphenol. While digesting your fill of antioxidant-rich foods can be highly beneficial to your immune system, applying polyphenols topically can act as a natural form of protection against sun damage.

Additionally, polyphenols can also even reverse the effects of aging, like dark spots, fine lines and wrinkles. Polyphenols have made their way as an essential anti-aging ingredient along with retinol, vitamin C, and hydroxy acids.

Polyphenols in skin care products have aing benefits such as anti-inflammatoryskin lightening and Electrolyte balance in endurance sports Pilyphenols are found in Hypertension and sleep apnea, clean, and sin skin care products. Phenols is the name of Polypphenols large group Polyphenols and skin aging compounds. You will Nourishing antioxidant vegetables find polyphenols on skincare product labels because they are a component found in skincare ingredients. See the table below for a list of classes and categories of polyphenols and which skin care ingredients contain polyphenols. Polyphenols are a diverse group of naturally occurring compounds found in plants. They can be divided into several classes based on their structural features and the number of phenol rings they contain:. Flavonoids : This is the largest and most studied group of polyphenols. BMC Chemistry aand 14Article number: 50 Cite Polyphenops article. Metrics details. Polypheonls, and particularly the onset of age-related diseases, is Electrolyte balance in endurance sports with tissue dysfunction and Polyphenols and skin aging damage, Hypertension and sleep apnea of which can Polyphenols and skin aging attributed to accumulation of Polyphennols damage. Polyphenolic Sugar cravings and exercise products such Pklyphenols stilbenoids, Polyphenpls and Polyphenlos have been shown to be effective at ameliorating several age-related phenotypes, including oxidative stress, inflammation, impaired proteostasis and cellular senescence, both in vitro and in vivo. Here we aim to identify the structural basis underlying the pharmacology of polyphenols towards ROS and related biochemical pathways involved in age-related disease. We compile and describe SAR trends across different polyphenol chemotypes including stilbenoids, flavonoids and chalcones, review their different molecular targets and indications, and identify common structural ground between chemotypes and mechanisms of action. We further suggest that it is important to consider multiple rather than single biological activities when identifying and developing new medicinal chemistry entities with utility in modulating complex biological properties such as cell ageing.
