[PMID: 38901681 DOI: 10.1016/j.jep.2024.118472] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/07/2024] [Revised: 06/12/2024] [Accepted: 06/17/2024] [Indexed: 06/22/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ficus erecta, a traditional Chinese She Ethnomedicine, has been historically utilized to treat various inflammatory conditions such as arthritis, nephritis, and osteoporosis. However, the underlying mechanisms accounting for its anti-inflammatory activity, as well as its active components, largely remain elusive. AIM OF THE STUDY The purpose of this research was to investigate the chemical constituents of F. erecta that contribute to its anti-inflammatory effects. MATERIALS AND METHODS Coumarins and flavones were obtained from the 95% EtOH extract of F. erecta using virous column chromatography and reversed-phase semipreparative HPLC. The structures of the new compounds were elucidated by extensive analysis of spectroscopic methods, including HRESIMS, 1D and 2D NMR spectra, and CD experiments. Cultured macrophage RAW264.7 cells were utilized for the anti-inflammatory experiments. MTT cell viability assay, Griess reagent method, ELISA, and Western blot experiments were employed to evaluate the anti-inflammatory activity and investigate the related mechanism. RESULTS Four new (1-4) and eleven previously identified (5-16) coumarins, together with one new (17) and six known flavones (18-23) were isolated from the whole plant of F. erecta. Compounds 7 and 17 significantly reduced nitric oxide (NO) and prostaglandin E2 (PGE2) production without cytotoxic effects. Furthermore, compounds 7 and 17 reduced the production of proinflammatory cytokines including tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6 in a concentration-dependent manner. Western blot analysis indicated that compounds 7 and 17 suppressed the expression of iNOS, COX-2, and p-IκBα in LPS-stimulated RAW264.7 macrophage cells. CONCLUSION The current phytochemical investigations revealed that coumarins and flavones represent the primary chemical constituents of F. erecta. Compounds 7 and 17 exhibit potent anti-inflammatory properties, linked with the inhibition of NF-κB activation by preventing the degradation of IκBα phosphorylation. These compounds may serve as promising candidates for treating or preventing certain inflammatory diseases.

Abstract
Coumarin, a plant secondary metabolite, has various pharmacological activities, including antioxidant stress and anti-inflammatory effects. Umbelliferone, a common coumarin compound found in almost all higher plants, has been extensively studied for its pharmacological effects in different disease models and doses with complex action mechanisms. This review aims to summarize these studies and provide useful information to relevant scholars. The pharmacological studies demonstrate that umbelliferone has diverse effects such as anti-diabetes, anti-cancer, anti-infection, anti-rheumatoid arthritis, neuroprotection, and improvement of liver, kidney, and myocardial tissue damage. The action mechanisms of umbelliferone include inhibition of oxidative stress, inflammation, and apoptosis, improvement of insulin resistance, myocardial hypertrophy, and tissue fibrosis, in addition to regulation of blood glucose and lipid metabolism. Among the action mechanisms, the inhibition of oxidative stress and inflammation is the most critical.

Abstract
Umbelliferone (UB) is a phenylpropanoid-based pharmacologically active agent with promising anti-tumor activities. However, complete elucidation of its therapeutic efficacy remains challenging due to low solubility and bioavailability. The present study aimed to develop a liposomal delivery system for UB to enhance its therapeutic efficacy against Dalton's ascites lymphoma tumor model. Umbelliferone-encapsulated nanoliposomes (nLUB) were prepared using the thin-film hydration method and performed a series of characterizations to confirm successful development. The nLUB showed a particle size of 116 ± 3.2 nm with a negative surface charge and encapsulation efficiency of 78%. In vitro study results showed that nLUB treatment significantly enhanced cellular uptake and apoptosis induction in lymphoma cells compared to free UB. nLUB treatment significantly stabilized body weight, reduced tumor growth, and improved the serum biochemical and hematological parameters of experimental animals, thereby improving their overall survivability compared to an free UB. Our result indicates that nanoencapsulation enhanced the therapeutic potential of UB, which may find its way to clinical application in the near future.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Potentilla plants are still common herbal medicines used in folk medicine. This review provides an update of research undertaken on Potentilla from 2009 until 2020. AIM OF THE STUDY This comprehensive review considers biological updates, recent advances in phytochemical and pharmacological research, and toxicological reports on Potentilla sensu lato based on available data since 2009. METHODS A literature search was conducted using available databases including ScienceDirect, PubMed, Scopus, Web of Science, China National Knowledge Infrastructure and Google Scholar. RESULTS Until now, more than 210 new and known compounds, including flavonoids, tannins, triterpenes and phenolic compounds, have been confirmed and elucidated for numerous Potentilla species, i.e., in the underground and aerial parts of this genus. Modern pharmacology studies have revealed that those structures are responsible for a broad spectrum of pharmacological activities, such as anti-neoplastic, antihyperglycemic, anti-inflammatory, antioxidant, hepatoprotective, neuroprotective, antibacterial and anti-yeast effects. CONCLUSIONS However, in vitro studies must be re-considered due to the discovery of urolithins and their origins, including microbiota, which can lead to different results when applying Potentilla species and their extracts to in vivo conditions. Thus, future research should focus more on in vivo and particularly clinical studies to confirm the validity and safety of traditional uses. Particularly, the use of Potentilla alba extracts in the treatment of thyroid gland disorders should be further explored to confirm the underlying mechanism of their action, efficacy and safety. In addition, more clinical studies should focus on Potentilla erecta rhizome extracts for application as herbal remedies against dysentery, diarrhoea and inflammation of the skin.

Abstract
Sepsis is a pathophysiological event involving systemic inflammatory response syndrome, multiple organ failure syndromes, and tissue damage. Overproduction of free radicals as a result of tissue damage during sepsis contributes to cellular toxicity, organ failure, and even mortality. Antioxidants, which scavenge free radicals, play a protective role against various diseases. Previous studies have shown that umbelliferone (UF) has antioxidant and anti-inflammatory effects. Since oxidative stress is naturally associated with sepsis-induced organ dysfunction, the application of antioxidant compounds could potentially illuminate the pathophysiology of sepsis, which does not yet have an effective treatment. The sepsis model induced by cecal ligation and puncture (CLP) was applied to rats. Different doses of UF (10░mg/kg, 20░mg/kg, and 40░mg/kg) on oxidant-antioxidant in septic rats, mRNA of inflammatory mediators such as tumor necrosis factor- α (TNF-α) and interleukin (IL)-1 its effects on expression levels were evaluated in lung, kidney, and liver tissues. When the lung, kidney, and liver tissues of septic rats were compared with those of the control group, it was found that UF administration increased dose-dependent superoxide dismutase activity and glutathione levels and significantly decreased malondialdehyde levels. The effects of UF administration on oxidative parameters were dose-dependent. The 40░mg/kg UF dose showed greater anti-oxidative properties than the 20░mg/kg and 10░mg/kg doses for all the evaluated parameters. Further, the TNF- α mRNA expression of the CLP +40░mg/kg group was reduced to a level comparable to that of the control group. UF has been found to be an effective molecule in reducing oxidative stress by supporting endogenous antioxidants and enhancing the scavenging effects of free radicals. The potent antioxidant property of UF may also be related to the suppression of the cytokine cascade during sepsis. The results suggest that UF administration may represent a new treatment for the prevention of lung, kidney and liver damage caused by septic conditions.

Coumarins as Modulators of the Keap1/Nrf2/ARE Signaling Pathway. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2020; 2020:1675957. [PMID: 32377290 PMCID: PMC7196981 DOI: 10.1155/2020/1675957] [Citation(s) in RCA: 117] [Impact Index Per Article: 29.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/24/2020] [Revised: 03/14/2020] [Accepted: 04/06/2020] [Indexed: 12/30/2022]
Abstract
The Keap1/Nrf2/ARE system is a central defensive mechanism against oxidative stress which plays a key role in the pathogenesis and progression of many diseases. Nrf2 is a redox-sensitive transcription factor controlling a variety of downstream antioxidant and cytodefensive genes. Nrf2 has a powerful anti-inflammatory activity mediated via modulating NF-κB. Therefore, pharmacological activation of Nrf2 is a promising therapeutic strategy for the treatment/prevention of several diseases that are underlined by both oxidative stress and inflammation. Coumarins are natural products with promising pharmacological activities, including antioxidant, anticancer, antimicrobial, and anti-inflammatory efficacies. Coumarins are found in many plants, fungi, and bacteria and have been widely used as complementary and alternative medicines. Some coumarins have shown an ability to activate Nrf2 signaling in different cells and animal models. The present review compiles the research findings of seventeen coumarin derivatives of plant origin (imperatorin, visnagin, urolithin B, urolithin A, scopoletin, esculin, esculetin, umbelliferone, fraxetin, fraxin, daphnetin, anomalin, wedelolactone, glycycoumarin, osthole, hydrangenol, and isoimperatorin) as antioxidant and anti-inflammatory agents, emphasizing the role of Nrf2 activation in their pharmacological activities. Additionally, molecular docking simulations were utilized to investigate the potential binding mode of these coumarins with Keap1 as a strategy to disrupt Keap1/Nrf2 protein-protein interaction and activate Nrf2 signaling.

Abstract
Regioselective access to 10-substituted-2H,8H-pyrano[2,3-f]chromen-2-ones through the gold-catalyzed intramolecular hydroarylation of readily available 7-(prop-2-yn-1-yloxy)-2H-chromen-2-one derivatives at their C-8 congested position was investigated by tuning the electronic and steric properties of the ligand on the gold complex. On the other hand, the combination of the JohnPhosAu(MeCN)SbF6 catalyzed intramolecular hydroarylation of 8-iodo-7-(prop-2-yn-1-yloxy)-2H-chromen-2-one derivatives followed by selective palladium/formate C-I reduction allows for the exclusive formation of 2H,8H-pyrano[3,2-g]chromen-2-one regioisomers. The development of these two protocols provides versatile synthetic tools required for exploring the biological activities of these new pyranocoumarin derivatives.

Abstract
The Poaceae family, known as grasses, is distributed worldwide and is considered the most important group of monocotyledonous crops. Salt stress is multifactorial, therefore to survive, halophytes evolved a variety of adaptations, which include the biosynthesis of different primary and secondary metabolites. This trait enhances the accumulation of important families of compounds crucial to the prevention of a variety of chronic diseases. Besides, if proven edible, these species could cope with the increased soil salinity responsible for the decline of arable land due to their high nutritional/nutraceutical value. Herein, the phytochemical investigations performed in halophytes from the Poaceae family as well as their biological properties were explored. Among the 65 genera and 148 species of known halophytic grasses, only 14% of the taxa were studied phytochemically and 10% were subjected to biological evaluation. Notably, in the studied species, a variety of compound families, as well as bioactivities, were demonstrated, highlighting the potential of halophytic grasses.

The aim of the current work was to explore the muscle relaxant effect of pistagremic acid (PA) isolated from Pistacia integerrima in various animal paradigms. In a rotarod test, PA caused a significant (p<0.05) muscle relaxant potential in a dose-dependent manner. When studied in the inclined plane test, pretreatment with PA (5 and 10 mg/kg) caused promising activity (p<0.05) after treatment for 30, 60 and 90 min. The muscle relaxant potential of PA was strongly complimented by the traction and chimney tests, showing a dominant effect after 60 min of treatment. In conclusion, PA possesses strong muscle relaxant activity in various animal-based models.

Abstract
Coumarin and curcumin have a wide spectrum of biological and pharmacological activities including antioxidant, anti-inflammatory, antimicrobial and anticancer but hindered therapeutic applications due to low stability and poor solubility in water. The main objective of the current study was to overcome these drawbacks via improved bioavailability by nanoencapsulated emulsions. Pickering emulsion (PE) via oil-in-water approach were stabilized by aminated nanocellulose (ANC) particles through application of a full factorial optimization design for nanoemulsions containing different composition of oil phase with medium chain triglyceride (MCT) and Tween 80. The fabricated nanoemulsions and PEs with average particle sizes (≤150 nm) were obtained. Influencing factors such as ANC concentration, storage time and pH on the stability of emulsions were examined alongside zeta potentials. Encapsulation efficiency (EE) of coumarin and curcumin were determined as >90%. Release kinetic profiles for encapsulated PEs displayed sustained release with supposed increase bioavailability. Higher release percent were detected for curcumin encapsulated PE in contrast to coumarin. In vitro cytotoxicity evaluation for coumarin and curcumin loaded PEs were further investigated for anticancer and antimicrobial activities using human cell lines (L929 and MCF-7) and different microorganisms (Gram (+), Gram (-) and fungi), respectively. The results clearly demonstrated PE coumarin and curcumin as promising candidates to inhibit microbial growth and to prevent preferential killing of cancer cells compared to normal cells.

Abstract
It is well documented that anomalous production of inflammatory proteins linked with most of the toxic expression and genesis of diverse chronic disease including cancer. Diethylnitrosamine (DEN) a well-known hepatotoxin and hepatocarcinogen, can induce oxidative stress and inflammatory reaction in it. Umbelliferone, secondary metabolites, is present in different plants and widely consumed by humans as medicine and food supplements. The aim of the current study was to scrutinize the chemoprotective potential of umbelliferon-α-d-glucopyranosyl-(2I→1II)-α-d-glucopyranoside (UFD) against DEN-induced hepatocellular carcinoma (HCC) in experimental rats. Single intraperitoneal injection of DEN (200mg/kg) was used for induction of HCC in rats and rats were grouped and orally treated with UFD (5, 10 and 20mg/kg) dose for 22 weeks. Parameters under investigation included hepatic, non-hepatic enzymes, oxidative stress, pro-inflammatory cytokines, COX-2 and NF-κB level along with histopathological examination in HCC rats. UFD exerted protective effect via reduction of oxidative stress, liver and non-liver parameters in a dose-dependent manner. It also reduced the expression of TNF-α, IL-1β, IL-6 and COX-2 in diseased rats. Our result revealed the essential repression of the inflammation cascade through modulation of nuclear factor-kappa B (NF-κB) signaling pathway.

Abstract
BACKGROUND It is well known that diabetes is one of the non-communicable disease affecting a large population worldwide. When diabetes remains untreated or uncontrolled, it leads to further serious complications, affecting vital organs like eyes, kidney, heart, etc. The present study was designed to evaluate effects of umbelliferone, a phytochemical, in treatment of diabetic nephropathy. METHODS Experimental model used was streptozotocin (55mg/kg, ip) induced diabetic nephropathy in male Sprague Dawley rats. After 28days of streptozotocin administration, diabetic animals were treated with umbelliferone at two dose levels, 20 and 40mg/kg for next 28days. RESULTS The results of the study showed that umbelliferone treatment significantly decreased the elevated plasma creatinine and blood urea nitrogen level while significantly increased the total protein and albumin level in diabetic animals. Creatinine clearance was improved in umbelliferone treated animals. Renal oxidative stress was decreased in umbelliferone treated animals significantly. Histopathological study of the kidney was carried out by specific stains like Hematoxylin-Eosin, Periodic Acid Schiff and Masson Trichrome stain. The sections of the kidney showed that umbelliferone treatment decreased the glomerular damage, mesangial matrix expansion as well as the renal fibrosis. Determination of renal transforming growth factor beta one (TGF-β1) expression by immunohistochemical analysis, western blotting and circulating TGF-β1 by ELISA assay showed that umbelliferone decreased the renal tissue and circulating TGF-β1 level. CONCLUSION Umbelliferone treatment can significantly reduce the diabetes induced renal damage and can improve the pathological conditions related to the diabetic nephropathy by down regulation of TGF-β.

Abstract
BACKGROUND Umbelliferone, also known as 7-hydroxycoumarin, is a phenolic metabolite found in many familiar plants. Its derivatives have been shown to have various pharmacological and chemo-preventive effects on human health. A uridine diphosphate glycosyltransferase YjiC from Bacillus licheniformis DSM 13, a cytochrome P450BM3 (CYP450 BM3) variant namely mutant 13 (M13) from Bacillus megaterium, and an O-methyltransferase from Streptomyces avermitilis (SaOMT2) were used for modifications of umbelliferone. RESULTS Three umbelliferone derivatives (esculetin, skimmin, and herniarin) were generated through enzymatic and whole cell catalysis. To improve the efficiencies of biotransformation, different media, incubation time and concentration of substrate were optimized and the production was scaled up using a 3-L fermentor. The maximum yields of esculetin, skimmin, and herniarin were 337.10 μM (67.62%), 995.43 μM (99.54%), and 37.13 μM (37.13%), respectively. The water solubility of esculetin and skimmin were 1.28-folds and 3.98-folds as high as umbelliferone, respectively, whereas herniarin was 1.89-folds less soluble than umbelliferone. Moreover, the antibacterial and anticancer activities of herniarin showed higher than umbelliferone, esculetin and skimmin. CONCLUSIONS This study proves that both native and engineered enzymes could be employed for the production of precious compounds via whole cell biocatalysis. We successfully produced three molecules herniarin, esculetin and skimmin in practical amounts and their antibacterial and anticancer properties were accessed. One of the newly synthesized molecules the present research suggests that the combinatorial biosynthesis of different biosynthetic enzymes could rapidly promote to a novel secondary metabolite.

5-Methoxyl Aesculetin Abrogates Lipopolysaccharide-Induced Inflammation by Suppressing MAPK and AP-1 Pathways in RAW 264.7 Cells. Int J Mol Sci 2016; 17:315.

Abstract
For the first time, a pale amorphous coumarin derivative, 5-methoxyl aesculetin (MOA), was isolated from the dried bark of Fraxinus rhynchophylla Hance (Oleaceae). MOA modulates cytokine expression in lipopolysaccharide (LPS)-treated RAW 264.7 macrophages, but the precise mechanisms are still not fully understood. We determined the effects of MOA on the production of inflammatory mediators and pro-inflammatory cytokines in the LPS-induced inflammatory responses of RAW 264.7 macrophages. MOA significantly inhibited the LPS-induced production of nitric oxide (NO), prostaglandin E₂ (PGE₂), tumor necrosis factor-α (TNF-α), interleukin-6, and interleukin-1β. It also effectively attenuated inducible nitric oxide (NO) synthase, cyclooxygenase-2, and TNF-α mRNA expression and significantly decreased the levels of intracellular reactive oxygen species. It inhibited phosphorylation of the extracellular signal-regulated kinase (ERK1/2), thus blocking nuclear translocation of activation protein (AP)-1. In a molecular docking study, MOA was shown to target the binding site of ERK via the formation of three hydrogen bonds with two residues of the kinase, which is sufficient for the inhibition of ERK. These results suggest that the anti-inflammatory effects of MOA in RAW 264.7 macrophages derive from its ability to block both the activation of mitogen-activated protein kinases (MAPKs) and one of their downstream transcription factors, activator protein-1 (AP-1). Our observations support the need for further research into MOA as a promising therapeutic agent in inflammatory diseases.

Abstract
The present study deals with the anti-hyperalgesic and anti-inflammtory effects of flavonoids (1-4) isolated from the chloroform fraction of Pistacia integerrima galls. The structure of isolated compounds was elucidated by using advance spectroscopy analysis and comparing their physical spectral data with reported one. The pretreatment of compounds (1-4) caused significant anti-hyperalgesic effects in acetic acid induced writhing test in a dose dependent manner. The compounds strongly complimented the effects in both phases of formalin test. However, the administration of naloxone did not abolish the induced antinociceptive effects and therefore suggested the absence of opioid receptor involvement. The pretreatment of flavonoids (1-4) elicited marked anti-inflammtory effects in carrageenan induced paw edema test in mice during various assessment times (1-5 h). The effects were dose dependent and maximum results were observed after 3rd h of treatments which remained significant up to 5th hour. It is concluded that the isolated flavonoids (1-4) possessed strong anti-hyperalgesic and anti-inflammtory activity and thus are strong candidates for further detail studies.

Abstract
Background Fever and pain management is a very challenging job for the clinician as the available synthetic agents are causing serious side effects. The present research article deals with the antipyretic and antinociceptive activity of extract/fractions of Potentilla evestita and acacetin isolated from the chloroform fraction of the plant. Methods Various chromatographic and spectroscopic techniques were used for the isolation and characterizion of compound. In-vivo yeast induced fibrile mice were used for antipyretic activity while acetic acid induced writhing and formalin tests were used for antinociceptive. Results The extract/fractions of P. evestita caused marked antipyretic effect during various assessment times in which chloroform was the most prominent followed by ethyl acetate. When acacetin was injected, it produced marked effect with maximum activity of 33.28% and 55.01% at 5 and 10 mg/kg i.p respectively. When studied in acetic acid induced writhing test, the extract/fractions evoked significant antinociceptive effect in which chloroform was the most effective fraction followed by ethyl acetate. Acacetin showed significant antinociceptive effect with 44.77% and 67.03% reduction in abdominal constriction at 5 and 10 mg/kg i.p., respectively. Similarly, it evoked significant dose dependent reduction in noxious stimulation with 42.07% and 64.57% pain attenuation at 5 and 10 mg/kg i.p., respectively in initial phase. In the late phase, it illustrated more dominant effect with 46.32% and 67.29% reduction of painful sensation. Conclusions In conclusion, the extract/fractions of P. evestita as well as the isolated compound, acacetin showed strong antipyretic and antinociceptive activity in various animal models possibly mediated through both peripheral and central mechanism.
