Hua H, Liu L, Zhu T, Cheng F, Qian H, Shen F, Liu Y. Healthy regulation of Tibetan Brassica rapa L. polysaccharides on alleviating hyperlipidemia: A rodent study. FOOD CHEMISTRY. MOLECULAR SCIENCES 2023; 6:100171. [PMID: 37179738 PMCID: PMC10172908 DOI: 10.1016/j.fochms.2023.100171] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Revised: 03/27/2023] [Accepted: 04/08/2023] [Indexed: 05/15/2023]
Abstract
Hyperlipidemia is a common metabolic disorder, which can lead to obesity, hypertension, diabetes, atherosclerosis and other diseases. Studies have shown that polysaccharides absorbed by the intestinal tract can regulate blood lipids and facilitate the growth of intestinal flora. This article aims to investigate whether Tibetan turnip polysaccharide (TTP) plays a protective role in blood lipid and intestinal health via hepatic and intestinal axes. Here we show that TTP helps to reduce the size of adipocytes and the accumulation of liver fat, playing a dose-dependent effect on ADPN levels, suggesting an effect on lipid metabolism regulation. Meantime, TTP intervention results in the downregulation of intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and serum inflammatory factors (interleukin-6 (IL-6), interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α)), implying that TTP suppresses the progression of inflammation in the body. The expression of key enzymes associated with cholesterol and triglyceride synthesis, such as 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR), cholesterol 7α-hydroxylase (CYP7A1), peroxisome proliferator-activated receptors γ (PPARγ), acetyl-CoA carboxylase (ACC), fatty acid synthetase (FAS) and sterol-regulatory element binding proteins-1c (SREBP-1c), can be modulated by TTP. Furthermore, TTP also alleviates the damage to intestinal tissues caused by high-fat diet, restores the integrity of the intestinal barrier, improves the composition and abundance of the intestinal flora and increases the levels of SCFAs. This study provides a theoretical basis for the regulation of body rhythm by functional foods and potential intervention in patients with hyperlipidemia.

Abstract
Herbicide atrazine restricts nutrient accumulation and thus inhibits the growth of sensitive crops. The application of organic fertilizer is a common measure that contributes to modulating abiotic tolerance of crops and providing nutrients, but its advantages in combination with atrazine degrading microorganisms as bio-organic fertilizer to alleviate atrazine stress on sensitive crops and the associated mechanisms are unknown. We investigated the beneficial effects of organic and bio-organic fertilizer (named DNBF10) containing Arthrobacter sp. DNS10 applications on growth, leaf nitrogen accumulation, root surface structure and root physiological properties of soybean seedlings exposed to 20 mg kg-1 atrazine in soil. Compared with organic fertilizer, bio-organic fertilizer DNBF10 exhibited more reduction in soil atrazine residue and plant atrazine accumulation, as well as alleviation in atrazine-induced root oxidative stress and damaged cells of soybean roots. Transcriptome analysis revealed that DNBF10 application enhanced nitrogen utilization by improving the expression of genes involved in nitrogen metabolism in soybean leaves. Besides, genes expression of cytochrome P450 and ABC transporters involved in atrazine detoxification and transport in soybean leaves were also down-regulated by DNBF10 to diminish phytotoxicity of atrazine to soybean seedlings. These results illustrate the molecular mechanism by which the application of DNBF10 alleviates soybean seedlings growth under atrazine stress, providing a step forward for mitigate the atrazine induced inhibition on soybean seedlings growth through decreasing atrazine residues as well as enhancing damaged root repair and nitrogen accumulation.

Abstract
The preparation of nonanomeric C-acyl-saccharides has been developed from two different carboxylic acid feedstocks. This transformation is driven by the synergistic interaction of an electron donor-acceptor complex and Ni catalysis. Primary-, secondary-, and tertiary redox-active esters are incorporated as coupling partners onto preactivated pyranosyl- and furanosyl acids, preserving their stereochemical integrity. The reaction occurs under mild conditions, without stoichiometric metal reductants or exogenous catalysts, using commercially available Hantzsch ester as the organic photoreductant.

Abstract
Covering: 2000-2022Plants collectively synthesize a huge repertoire of metabolites. General metabolites, also referred to as primary metabolites, are conserved across the plant kingdom and are required for processes essential to growth and development. These include amino acids, sugars, lipids, and organic acids. In contrast, specialized metabolites, historically termed secondary metabolites, are structurally diverse, exhibit lineage-specific distribution and provide selective advantage to host species to facilitate reproduction and environmental adaptation. Due to their potent bioactivities, plant specialized metabolites attract considerable attention for use as flavorings, fragrances, pharmaceuticals, and bio-pesticides. The Solanaceae (Nightshade family) consists of approximately 2700 species and includes crops of significant economic, cultural, and scientific importance: these include potato, tomato, pepper, eggplant, tobacco, and petunia. The Solanaceae has emerged as a model family for studying the biochemical evolution of plant specialized metabolism and multiple examples exist of lineage-specific metabolites that influence the senses and physiology of commensal and harmful organisms, including humans. These include, alcohols, phenylpropanoids, and carotenoids that contribute to fruit aroma and color in tomato (fruity), glandular trichome-derived terpenoids and acylsugars that contribute to plant defense (stinky & sticky, respectively), capsaicinoids in chilli-peppers that influence seed dispersal (spicy), and steroidal glycoalkaloids (bitter) from Solanum, nicotine (addictive) from tobacco, as well as tropane alkaloids (deadly) from Deadly Nightshade that deter herbivory. Advances in genomics and metabolomics, coupled with the adoption of comparative phylogenetic approaches, resulted in deeper knowledge of the biosynthesis and evolution of these metabolites. This review highlights recent progress in this area and outlines opportunities for - and challenges of-developing a more comprehensive understanding of Solanaceae metabolism.

Abstract
Plants synthesize myriad phylogenetically restricted specialized (aka “secondary”) metabolites with diverse structures. Metabolism of acylated sugar esters in epidermal glandular secreting trichomes across the Solanaceae (nightshade) family is ideal for investigating the mechanisms of evolutionary metabolic diversification. We developed methods to structurally analyze acylhexose mixtures by 2D NMR, which led to the insight that the Old World species black nightshade (Solanum nigrum) accumulates acylglucoses and acylinositols in the same tissue. Detailed in vitro biochemistry, cross-validated by in vivo virus-induced gene silencing, revealed two unique features of the four-step acylglucose biosynthetic pathway: A trichome-expressed, neofunctionalized invertase-like enzyme, SnASFF1, converts BAHD-produced acylsucroses to acylglucoses, which, in turn, are substrates for the acylglucose acyltransferase, SnAGAT1. This biosynthetic pathway evolved independently from that recently described in the wild tomato Solanum pennellii, reinforcing that acylsugar biosynthesis is evolutionarily dynamic with independent examples of primary metabolic enzyme cooption and additional variation in BAHD acyltransferases.

Abstract
Brassica rapa L. is one of the most popular traditional foods with a variety of biological activities. In this study, the petroleum ether extract of B. rapa was separated by silica gel column chromatography, and named BRPS, which was identified by LC-MS. The effects and pharmacological mechanisms of BRPS on the treatment of lung cancer were investigated both in vitro and in vivo. The results showed that BRPS significantly inhibited the proliferation of both human lung cancer A549 and mouse lung cancer LLC cells, while its toxicity to normal cells was lower than that of cancer cells. BRPS induced cell cycle arrest at the G2/M phase and significantly reduced the levels of CDK1 and CyclinB1 in A549 cells. Moreover, BRPS induced apoptosis in a dose-dependent manner, and increased the Bax/Bcl-2 ratio, while it decreased mitochondrial membrane potential, promoted the release of cytochrome c, activated caspase 9 and 3, and enhanced the degradation of PARP in A549 cells. Furthermore, the levels of reactive oxygen species (ROS) were also upregulated by BRPS and ROS inhibitor reversed BRPS-induced apoptosis. Importantly, BRPS significantly suppressed the growth of LLC cells in vivo without any obvious side effect on body weight and organs of mice, and increased the proportion of B cells, CD4+ T cells, CD8+ T cells and CD44+CD8+ T cells in the spleen. These results revealed that BRPS inhibited the growth of lung cancer cells through inducing cell cycle arrest, mitochondria-dependent apoptosis, and activating immunity of mice, and BRPS might be a potential anti-tumor functional food and promising agent for the treatment of lung cancer.

Abstract
Brassica sprouts are known as a good source of antimicrobial bioactive compounds such as phenolics and glucosinolates (GLs). We aim at understanding how He-Ne laser light treatment (632 nm, 5 mW) improves sprout growth and physiology and stimulates the accumulation of bioactive metabolites in three Brassica spp., i.e., mustard, cauliflower, and turnip. Moreover, how these changes consequently promote their biological activities. Laser light improved growth, photosynthesis, and respiration, which induced the accumulation of primary and secondary metabolites. Laser light boosted the levels of pigments, phenolics, and indole and aromatic precursors of GLs, which resulted in increased total GLs and glucoraphanin contents. Moreover, laser light induced the myrosinase activity to provoke GLs hydrolysis to bioactive sulforaphane. Interestingly, laser light also reduced the anti-nutrient content and enhanced the overall biological activities of treated sprouts including antioxidant, antibacterial, anti-inflammatory, and anticancer activities. Accordingly, laser light is a promising approach for boosting the accumulation of beneficial metabolites in Brassica sprouts and, subsequently, their biological activities.

Abstract
Vegetable oils are characterized by their bioactive phytochemicals including fatty acids, tocols, and phenolic compounds. In the current study, turnip (Brassica rapa) oil was evaluated for its fatty acid profiles, tocol composition, and total phenolic content. The radical scavenging properties of oil against DPPH· and galvinoxyl radicals were also evaluated. Turnip oil efficiency in treating osteoporosis was tested in rats. Fifty adult female Sprague-Dawley albino rats were divided to five groups (n = 10/group). An osteoporotic rat model was prepared by two separate 5-day (5 days on/9 days off) courses of methotrexate subcutaneous injection. Osteoporotic rats were orally gavaged with turnip oil (200 and 400 mg/kg/day) for 28 days. Turnip oil efficiency in treating osteoporosis was studied by evaluation of Osterix, Cath K, and TNF-α transcript expression levels that involved in bone remodeling in femoral bones. Minerals and vitamin D were estimated in blood serum. Femoral bone histological and morphometric analyses were investigated in osteoporotic and turnip oil-treated rats. In vitro assays revealed strong antiradical potential of turnip oil. Treatment with turnip oil regulated the levels of Osterix, Cath K, and TNF-α mRNA that was accompanied with elevating the levels of calcium, phosphorous, bone alkaline phosphatase (BALP), and vitamin D in osteoporotic rats. The histological and morphometric inspection revealed that turnip oil displayed progress in the osteoporotic rat bone formation that was clear in the enhancement of thickness of femur shaft cortical bone and femur head trabecular bone. Above-mentioned findings indicated that turnip oil has the potential to share in the treatment of osteoporosis.

Abstract
Eight undescribed isorhamnetin glycosides, acylated with isovaleric acid were isolated from the fruit of sea buckthorn (Elaeagnus rhamnoides (L.) A. Nelson). Structures of the purified compounds were determined using one and two-dimensional NMR spectroscopy, mass spectrometry and chemical methods. In addition, the cytotoxic activity of the phenolic-rich fraction of sea buckthorn fruit and its major flavonoids against colon cell lines, HT-29, HCT-116 and Caco-2, was determined. While the phenolic fraction was moderately active against HT-29 and HCT-116, all investigated purified flavonoids showed significantly weaker activity. This is most probably the first report about isorhamnetin glycosides acylated with isovaleric acid.

Fan P, Leong BJ, Last RL. Tip of the trichome: evolution of acylsugar metabolic diversity in Solanaceae. CURRENT OPINION IN PLANT BIOLOGY 2019; 49:8-16.

Abstract
Acylsugars are insecticidal plant specialized metabolites produced in the Solanaceae (nightshade family). Despite having simple constituents, these compounds are unusually structurally diverse. Their structural variations in phylogenetically closely related species enable comparative biochemical approaches to understand acylsugar biosynthesis and pathway diversification. Thus far, varied enzyme classes contributing to their synthesis were characterized in cultivated and wild tomatoes, including from core metabolism - isopropylmalate synthase (Leu) and invertase (carbon) - and a group of evolutionarily related BAHD acyltransferases known as acylsucrose acyltransferases. Gene duplication and neofunctionalization of these enzymes drove acylsugar diversification both within and beyond tomato. The broad set of evolutionary mechanisms underlying acylsugar diversity in Solanaceae make this metabolic network an exemplar for detailed understanding of the evolution of metabolic form and function.

Abstract
Despite the advancement of medical science, diseases are part-and-parcel of human life. Plants have provided humans with medicines since time immemorial, and are still one of the primary sources for drug discovery. Brassica rapa L., commonly known as turnip, is one of the world's oldest cultivated vegetables. Besides being an important vegetable and source of oil, turnip is also used as a traditional medicine for the treatment of headaches, chest complaints, rheumatisms, oedemas, gonorrhoea, syphilis, and rabies. Glucosinolates and isothiocyanates (mainly 2-phenylethyl, 4-pentenyl, and 3-butenyl derivatives) are the main constituents of turnip with diverse bioactivities, especially for the protective effect against cancers. Besides, flavonoids, phenolics, indoles and volatiles are also concomitant in this plant. Pharmacological investigation on turnip revealed the antitumor, antihypertensive, antidiabetic, antioxidant, antiinflammatory, hepatoprotective, and nephroprotective effects. The anticancer property was found to be the most promising biological activity of turnip with 2-phenylethyl isothiocyanate, phenylpropionitrile, brassicaphenanthrene A, 6-paradol, and trans-6-shogaol as the major active constituents. Flavonoids and phenolics with high free radical scavenging activity should be corresponding to the antioxidant effects. Arvelexin, an indole derivative in turnip, was reported with various effects involving antiinflamatory, antihypertensive and hypolipidemic potency. In spite of many studies concerning either the chemical constituents or the biological activities of turnip, only a few cases disclosed the active ingredients responsible for diverse bioactivities. This review summarizes the research progress on the chemistry and health-benefits of turnip over the past 20 years to provide a reference for the further investigation.

Abstract
The incorporation of C-glycosides in drug design has become a routine practice for medicinal chemists. These naturally occurring building blocks exhibit attractive pharmaceutical profiles, and have become an important target of synthetic efforts in recent decades. Described herein is a practical, scalable, and versatile route for the synthesis of non-anomeric and unexploited C-acyl glycosides through a Ni/photoredox dual catalytic system. By utilizing an organic photocatalyst, a range of glycosyl-based radicals are generated and efficiently coupled with highly functionalized carboxylic acids at room temperature. Distinctive features of this transformation include its mild conditions, impressive compatibility with a wide array of functional groups, and most significantly, preservation of the anomeric carbon: a handle for further, late-stage derivatization.

Abstract
A new strategy for the synthesis of acyl β-C-glycosides is described. The reactivity of glyconitriles toward organometallic reagents such as organomagnesium or organolithium derivatives was studied, affording acyl β-C-glycosides in moderate to good yields. In this study, glycal formation was efficiently prevented by deprotonating the hydroxyl group in position 2 of the glyconitriles during the process.

Abstract
Aims: Kangaisan is a powdered compound prescription of Traditional Chinese Medicine which has been used in cancers for many years in Hubei province, China. The purpose of this study was to investigate the antitumor effects of Kangaisan and screen bioactive components. Materials and Methods: 3-(4,5-Dimethythiazol-2-yl)-2,5 diphenyl-tetrazolium bromide (MTT) assay, flow cytometry, DNA (Deoxyribonucleic acid) fragmentation assay, Western blot, and real time-polymerase chain reaction were used to investigate the antiproliferation effect of n-butyl-β-D-fructofuranoside on Bel-7402 cells. Statistical Analysis: All experiments were performed in triplicate and the results were expressed as mean ± standard deviation. Statistical analysis was performed with analysis of variance using Origin 8.0 software. Results: It was illustrated that treatment of Bel-7402 cells with various concentrations of n-butyl-β-D-fructofuranoside resulted in growth inhibition in both a dose-dependent and time-dependent manner. The arrest of G0/G1 phase was also induced (P < 0.05). The increasing of sub-G1 cell population indicated the apoplectic characteristic (P < 0.05). Furthermore, the emerging of DNA fragmentation and the increase of Bax/Bcl-2 ratio and p53 expression suggested the possible mitochondrial apoptotic pathway (P < 0.05). Conclusions: The results illustrate that Kangaisan showed anticancer effects and n-butyl-β-D-fructofuranoside extracted from Kangaisan can suppress Bel-7402 cells via interfering cell cycle and by inducing apoptosis.

Abstract
This study was undertaken to investigate the anti-arthritic potential of a standardized ethyl acetate fraction from the roots of Brassica rapa (EABR) and to explore the molecular mechanisms in adjuvant-induced arthritic rats and macrophages. In AIA-induced arthritic rats, EABR significantly reduced paw swelling, an arthritic index, serum rheumatoid factor, and tissue expression ratio of RANKL/OPG versus vehicle-administered group. This was found to be well correlated with significant suppressions in productions of PGE2, NO, and pro-inflammatory cytokines and in activations of NF-κB in AIA-induced paw tissues and LPS-induced macrophages. EABR attenuated NF-κB activation by reducing the nuclear translocation and phosphorylation of the p65 NF-κB, which were accompanied by parallel reductions in the degradation and phosphorylation of IκBα after blocking the phosphorylation mediated IKK activation. The findings suggest EABR exerts its anti-arthritic and anti-inflammatory properties via NF-κB inactivation in vitro and in vivo, and that EABR is a potential therapeutic for the treatment of arthritis and inflammation-associated disorders.

Abstract
The transgenic rice cultivar of Oryza sativa spp. japonica cv. Hwa-Young, C1/R-S transgenic rice (C1/R-S rice), is a flavonoid-rich cultivar of rice. The grains of C1/R-S rice were extracted with aqueous MeOH, and the concentrated extract was partitioned with EtOAc, n-BuOH, and H2O, successively. Repeated silica gel, octadecyl silica gel (ODS), and Sephadex LH-20 column chromatographies for the EtOAc and n-BuOH fractions afforded four new flavonoids (compounds 2, 3, 7, and 8) along with four known flavonoids: (+)-3'-O-methyltaxifolin (1), brassicin (4), isorhamnetin-4'-O-β-D-glucosyranoside (5), and 3'-O-methyltaxifolin-5-O-β-D-glucopyranoside (6). The new flavonoids were identified as 3'-O-methyltaxifolin-7-O-β-D-glucopyranoside (2), 3'-O-methyltaxifolin-4'-O-β-D-glucopyranoside (3), isorhamnetin-7-O-β-D-cellobioside (brassicin-4″-O-β-D-glucopyranoside) (7), and brassicin-4'-O-β-D-glucosyranoside (8) from the result of spectroscopic data including nuclear magnetic resonance spectrometry (NMR), mass spectrometry (MS), and infrared spectroscopy (IR). Also, quantitative analysis of major flavonoids (compounds 2, 3, and 8) in C1/R-S rice, O. sativa spp. japonica cv. Hwa-Young (HY), and a hybrid of two cultivar (C1/R-S rice/HY) extracts was performed using HPLC experiment. The isolated flavonoids were evaluated for their radical-scavenging effect on DPPH and ABTS radicals.
