KN37 in Agricultural Applications. Molecules 2024; 29:2040. [PMID: 38731531 PMCID: PMC11085741 DOI: 10.3390/molecules29092040] [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: 03/20/2024] [Revised: 04/22/2024] [Accepted: 04/27/2024] [Indexed: 05/13/2024] Open
Abstract
Actinomycetes have long been recognized as an important source of antibacterial natural products. In recent years, actinomycetes in extreme environments have become one of the main research directions. Streptomyces sp. KN37 was isolated from the cold region of Kanas in Xinjiang. It demonstrated potent antimicrobial activity, but the primary active compounds remained unclear. Therefore, we aimed to combine genomics with traditional isolation methods to obtain bioactive compounds from the strain KN37. Whole-genome sequencing and KEGG enrichment analysis indicated that KN37 possesses the potential for synthesizing secondary metabolites, and 41 biosynthetic gene clusters were predicted, some of which showed high similarity to known gene clusters responsible for the biosynthesis of antimicrobial antibiotics. The traditional isolation methods and activity-guided fractionation were employed to isolate and purify seven compounds with strong bioactivity from the fermentation broth of the strain KN37. These compounds were identified as 4-(Diethylamino)salicylaldehyde (1), 4-Nitrosodiphenylamine (2), N-(2,4-Dimethylphenyl)formamide (3), 4-Nitrocatechol (4), Methylsuccinic acid (5), Phenyllactic acid (6) and 5,6-Dimethylbenzimidazole (7). Moreover, 4-(Diethylamino)salicylaldehyde exhibited the most potent inhibitory effect against Rhizoctonia solani, with an EC50 value of 14.487 mg/L, while 4-Nitrosodiphenylamine showed great antibacterial activity against Erwinia amylovora, with an EC50 value of 5.715 mg/L. This study successfully isolated several highly active antimicrobial compounds from the metabolites of the strain KN37, which could contribute as scaffolds for subsequent chemical synthesis. On the other hand, the newly predicted antibiotic-like substances have not yet been isolated, but they still hold significant research value. They are instructive in the study of active natural product biosynthetic pathways, activation of silent gene clusters, and engineering bacteria construction.

Abstract
Oxidative stress plays an important role in acetaminophen (APAP)-induced hepatotoxicity. Platanosides (PTSs) isolated from the American sycamore tree (Platanus occidentalis) represent a potential new four-molecule botanical drug class of antibiotics active against drug-resistant infectious disease. Preliminary studies have suggested that PTSs are safe and well tolerated and have antioxidant properties. The potential utility of PTSs in decreasing APAP hepatotoxicity in mice in addition to an assessment of their potential with APAP for the control of infectious diseases along with pain and pyrexia associated with a bacterial infection was investigated. On PTS treatment in mice, serum alanine aminotransferase (ALT) release, hepatic centrilobular necrosis, and 4-hydroxynonenal (4-HNE) were markedly decreased. In addition, inducible nitric oxide synthase (iNOS) expression and c-Jun-N-terminal kinase (JNK) activation decreased when mice overdosed with APAP were treated with PTSs. Computational studies suggested that PTSs may act as JNK-1/2 and Keap1-Nrf2 inhibitors and that the isomeric mixture could provide greater efficacy than the individual molecules. Overall, PTSs represent promising botanical drugs for hepatoprotection and drug-resistant bacterial infections and are effective in protecting against APAP-related hepatotoxicity, which decreases liver necrosis and inflammation, iNOS expression, and oxidative and nitrative stresses, possibly by preventing persistent JNK activation.

Abstract
Methicillin-resistant S. aureus (MRSA) are a threat to public health as they frequently reveal a multidrug-resistant pattern. Researchers all over the world are on an urgent hunt for new treatments to help fight infections before antibiotics become obsolete, and some natural alternatives, such as polyphenols, have already exhibited therapeutic properties. Therefore, this study aimed to determine the phenolic profile, antioxidant capacity, and antimicrobial activity against MRSA of the leaf, fruit, and stem bark extracts of Platanus hybrida. The polyphenols were extracted with a water/ethanol (20:80) mixture and the methodology included HPLC-DAD, DPPH, FRAP, and CuPRAC. To address this issue from a One Health perspective, the Kirby–Bauer disc diffusion method was performed against nine MRSA strains from three different sources (livestock, wild animals, and humans). Fourteen phenolics were identified and the leaf extract showed the highest phenolic content, followed by the fruit extract. The leaf extract also showed the highest antioxidant capacity while the fruit extract had the lowest antioxidant capacity. Both leaf and fruit extracts inhibited the growth of strains from all sources, while the stem bark extract did not inhibit the growth of human strains. This work highlights the complex chemical composition and the antioxidative and antimicrobial potential of extracts derived from P. hydrida.

Abstract
The aim of the present study was to investigate the phenolic composition and the biological properties of different Aerva lanata (L). Juss. herb extracts obtained with the use of accelerated solvent extraction (ASE), i.e., a green, ecological method, for cosmetic purposes. All samples exhibited high DPPH• (9.17–119.85 mg TE/g) and ABTS•+ (9.90–107.58 mg TE/g) scavenging activity. The extracts exhibited considerable anti-lipoxygenase (EC50 between 1.14 mg/mL and 3.73 mg/mL) and anti-xanthine oxidase (EC50 between 1.28 mg/mL and 3.72 mg/mL) activities, moderate chelating activity (EC50 between 1.58 mg/mL and 5.30 mg/mL), and high antioxidant potential in the ORAC assay (0.36–3.84 mM TE/g). Changes in the polyphenol profile of the analysed samples depending on the solvent and temperature used for the extraction were determined with the liquid chromatography/electrospray mass spectrometry (LC-ESI-MS/MS) method. Twenty-one phenolic compounds, including flavonoids and phenolic acids, were detected and quantified. It was shown that tiliroside was one of the main phenolic metabolites in the A. lanata (L.) Juss. herb., which may suggest that this compound may be largely responsible for the observed anti-inflammatory activity of the extracts. In addition, the studied extracts exhibited promising skin-related (anti-tyrosinase, anti-elastase, anti-collagenase, and anti-hyaluronidase) activity. This study showed that Aerva lanata (L.) Juss. contains high amounts of phenolic compounds, including tiliroside, and has good skin-related activities. Therefore, the plant may be interesting as a novel source of bioactive agents for cosmetic industries.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 93:153757.

Abstract
BACKGROUND Prolonged maintenance of proteome stability and functionality (proteostasis) is of emerging significance in aging retardation and healthspan. PURPOSE An enriched polyphenolic extract obtained from the hydrodistillation of rose petals was tested for its capacity to activate the proteostasis network modules, and thus modulate health- and/or lifespan at the cellular and whole organism level. METHODS The aqueous extract that remained after the hydrodistillation of Rosa damascena petals, was processed with a polystyrene-FPX66 adsorption resin and sequentially fractionated by FCPC. NMR and UHPLC-HRMS analyses revealed the presence of 28 metabolites, mainly glycosides of kaempferol and quercetin. RESULTS The extract showed high in vitro antioxidant activity and was not toxic in normal human skin fibroblasts, while it promoted the upregulation of NRF2-induced antioxidant genes and main proteostatic modules. Consistently, supplementation of this extract in Drosophila flies' culture medium induced a cncC/NRF2-mediated upregulation of antioxidant and proteostatic modules. Prolonged administration of the extract in flies' culture medium was not toxic and did not affect food intake rate or fecundity; also, it delayed the age-related decline of stress tolerance and locomotion performance (neuromuscular functionality) and dose-dependently extended flies' lifespan. CONCLUSION Our findings indicate that the enriched polyphenolic extract obtained from the residue of R. damascena hydrodistillation activates cytoprotective cellular modules that, likely, contribute to its potential anti-aging properties.

Abstract
aging is an inevitable biological complex process. It involves the gradual loss of cellular vitality due to accumulative damage to cellular macromolecules by reactive oxygen species (ROS). These ROS are highly implicated in health, disease, and lifespan. The biochemical pathways involved in the aging process are highly influenced by both exogenous (environmental factors) and endogenous stress factors. These cellular processes are the same in most organisms including the fruit fly, nematode, yeast, mammalian cell line, and rodents. These model organisms have been extensively used in the screening of potent antioxidant botanicals for anti-aging bioactivity. Moringa oleifera and Ananas sativa are great sources of health-promoting nutrients and antioxidants, however, their anti-aging impact is still an evolving area of research interest. Therefore, this review focused on their anti-aging mode of action and some other anti-aging nutriceuticals in different model organisms including the fruit fly. PRACTICAL APPLICATIONS: Staying forever young and healthy is everyone's right. Aside from genetic trait, healthy feeding is peculiar to the world's longest-living people. Ananas sativa (pineapple) and Moringa oleifera leaves are highly valued fruit and herb with nourishing, antioxidant, and medicinal properties. Their extract exhibit antioxidant, anticancer, anti-inflammatory, and anti-aging activities. The ancient Greeks, Egyptians, and Romans used Moringa seed oil for cosmetics and perfumes. Moringa tea leaves is consumed for its nutritive and medicinal value. Its antioxidant potency endorses its use for anti-aging and other health-promoting purposes. The bioactive compound in pineapple, bromelain, promotes wound healing and it is a component of postsurgical applications due to its anti-inflammatory property. Consumption of Ananas fruit provides the recommended daily allowance of vitamin C, a potent antioxidant. To identify new anti-aging bioactive compounds of therapeutic importance, and understanding the mode of action of these nutriceuticals will contribute to new anti-aging research prospects.

Abstract
Plants and their corresponding botanical preparations have been used for centuries due to their remarkable potential in both the treatment and prevention of oxidative stress-related disorders. Aging and aging-related diseases, like cardiovascular disease, cancer, diabetes, and neurodegenerative disorders, which have increased exponentially, are intrinsically related with redox imbalance and oxidative stress. Hundreds of biologically active constituents are present in each whole plant matrix, providing promissory bioactive effects for human beings. Indeed, the worldwide population has devoted increased attention and preference for the use of medicinal plants for healthy aging and longevity promotion. In fact, plant-derived bioactives present a broad spectrum of biological effects, and their antioxidant, anti-inflammatory, and, more recently, anti-aging effects, are considered to be a hot topic among the medical and scientific communities. Nonetheless, despite the numerous biological effects, it should not be forgotten that some bioactive molecules are prone to oxidation and can even exert pro-oxidant effects. In this sense, the objective of the present review is to provide a detailed overview of plant-derived bioactives in age-related disorders. Specifically, the role of phytochemicals as antioxidants and pro-oxidant agents is carefully addressed, as is their therapeutic relevance in longevity, aging-related disorders, and healthy-aging promotion. Finally, an eye-opening look into the overall evidence of plant compounds related to longevity is presented.

Abstract
Osteoporosis is a class of metabolic bone disease caused by complexed ramifications. Overactivation of osteoclasts due to a sudden decreased estrogen level plays a pivotal role for postmenopausal women suffering from osteoporosis. Therefore, inhibiting osteoclast formation and function has become a major direction for the treatment of osteoporosis. Tiliroside (Tle) is a salutary dietary glycosidic flavonoid extracted from Oriental Paperbush flower, which has been reported to have an anti-inflammation effect. However, whether Tle affects the osteoclastogenesis and bone resorption remains unknown. Herein, we demonstrate that Tle prevents bone loss in ovariectomy in mice and inhibits osteoclast differentiation and bone resorption stimulated by receptor activator of nuclear factor-κB ligand (RANKL) in vitro. Molecular mechanism studies reveal that Tle reduces RANKL-induced activation of mitogen-activated protein kinase and T-cell nuclear factor 1 pathways, and osteoclastogenesis-related marker gene expression, including cathepsin K (Ctsk), matrix metalloproteinase 9, tartrate-resistant acid phosphatase (Acp5), and Atp6v0d2. Our research indicates that Tle suppresses osteoclastogenesis and bone loss by downregulating the RANKL-mediated signaling protein activation and expression. In addition, Tle inhibits intracellular reactive oxygen species generation which is related to the formation of osteoclasts. Therefore, Tle might serve as a potential drug for osteolytic disease such as osteoporosis.

Abstract
Aging is a complex phenomenon caused by the time-dependent loss of cellular homeodynamics and consequently of physiological organismal functions. This process is affected by both genetic and environmental (e.g., diet) factors, as well as by their constant interaction. Consistently, deregulation of nutrient sensing and signaling pathways is considered a hallmark of aging. Nutrigenomics is an emerging scientific discipline that studies changes induced by diet on the genome and thus it considers the intersection of three topics, namely health, diet, and genomics. Model organisms, such as the fruit fly Drosophila melanogaster, have been successfully used for in vivo modeling of higher metazoans aging and for nutrigenomic studies. Drosophila is a well-studied organism with sophisticated genetics and a fully annotated sequenced genome, in which ~ 75% of human disease-related genes have functional orthologs. Also, flies have organs/tissues that perform the equivalent functions of most mammalian organs, while discrete clusters of cells maintain insect carbohydrate homeostasis in a way similar to pancreatic cells. Herein, we discuss the mechanistic connections between nutrition and aging in Drosophila, and how this model organism can be used to study the effect of different diets (including natural products and/or their derivatives) on higher metazoans longevity.

Abstract
Olive oil is widely accepted as a superior edible oil. Great attention has been given lately to olive oil polyphenols which are linked to significant health beneficial effects. Towards a survey of Greek olive oil focusing on polyphenols, representative extra virgin olive oils (EVOOs) from the main producing areas of the country and the same harvesting period have been collected and analyzed. Significant differences and interesting correlations have been identified connecting certain polyphenols namely hydroxytyrosol, tyrosol, oleacein and oleocanthal with specific parameters e.g. geographical origin, production procedure and cultivation practice. Selected EVOOs polyphenol extracts, with different oleacein and oleocanthal levels, as well as isolated oleacein and oleocanthal were bio-evaluated in mammalian cells and as a dietary supplement in the Drosophila in vivo model. We found that oleocanthal and oleacein activated healthy aging-promoting cytoprotective pathways and suppressed oxidative stress in both mammalian cells and in flies.

JOURNAL OF ANALYTICAL METHODS IN CHEMISTRY 2019; 2019:9052425. [PMID: 30729060 PMCID: PMC6343130 DOI: 10.1155/2019/9052425] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/22/2018] [Accepted: 12/02/2018] [Indexed: 05/26/2023]
Abstract
Tiliroside exhibits a wide spectrum of effects on the human body; considering expensive synthesis of tiliroside, linden trees seem to be a good source of this compound. For the first time, 46 various extraction methods were developed to receive tiliroside from Tilia L., including ultrasound-assisted extraction, maceration, maceration with stirring, accelerated solvent extraction, and extraction under reflux. The effects of extraction techniques, solvents, additives, and temperature on the content of tiliroside were studied using analytical and statistical methods. A new, rapid, simple, sensitive, and selective liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) method was developed to determine the content of tiliroside in Tilia L. flowers. The LC-ESI-MS/MS analysis demonstrated the highest content of tiliroside in Tilia L. flowers obtained using accelerated solvent extraction (ASE) where 70% ethanol with addition of 1% acetic acid was used as a solvent (7.400 ± 0.019 mg of tiliroside per g dry extract).The results showed that the extracts of Tiliae inflorescentia contained large amounts of tiliroside; therefore, they are good sources of this compound. Moreover, ASE was found to be superior to other extraction techniques due to its high efficiency as well as considerable saving of time and solvent.

Abstract
Among flavonoid derivatives, tiliroside is a flavonoid contained in several edible plants or specific plant parts (fruits, leaves, or roots). These parts are often widely used as both food and medicines, in the treatment of various ailments and, in some cases, as food supplements. Considering the easy access to many publications concerning tiliroside and the lack of a review that summarizes the current progress in studies on its safety, efficacy, and presence in the plant kingdom, we present here a review paper on tiliroside and its principal derivatives. The paper also highlights the basic knowledge regarding this molecule, its derivatives, and the analytical approaches used for extraction and quantification, as well as reports on the biological activities against different key enzymes linked to various human diseases. The reported information is also devoted to highlighting the concept "learn from nature to discover new products," particularly in the development of new drugs, food supplements, and nutraceuticals, starting from a natural lead compound such as tiliroside and improving its biological activities (and selectivities) against a specific target for therapeutic purposes.

Abstract
Abstract
Olive leaves (Olea europaea L.) contain phenolics that are used for various aims and can also be utilized as free radical scavengers and as a powerful antioxidant source. In this study, our aim was to observe the effects of olive phenolics on the survival rate, development, sex ratio, and adult longevity of Drosophila melanogaster Meigen (Diptera: Drosophilidae) fed with sugar and with a sugar-free diet. The amount of malondialdehyde and the activity of glutathione S-transferase were examined with UV-VIS spectrophotometry in third-stage larvae, pupae and adults. For this purpose, dried olive fruit and leaf extracts were added at different concentrations to the insect’s sugary diets. The results reveal that 12 mg/L phenolic fruit extract and 4 M sucrose had a negative impact on the development and survival of these insects. It was also found that phenolic leaf extract and low sugar concentrations changed the sex ratio, leading to fewer females and more males. The use of phenolic fruit and phenolic leaf extracts with increased sugar-based diets raised the amount of oxidation as well as the detoxification activity in this model organism. These results demonstrate that low amounts of sugar and olive phenolics may be used as an adjunct to adult nutrients to improve the insect’s adult characteristics.
