Abstract
Ligularia fischeriTurcz. is a medicinal plant for the treatment of inflammation in China and Korea. Its chemical components in anti-sepsis activity and the related molecular mechanisms remain unknown yet. In this study, two undescribed eremophilane sesquiterpenoids fischerins A (1) and B (2), together with 8 known sesquiterpenoid derivatives (3-10), were isolated from the whole plant of L. fischeri. Their structures were identified by detailed spectroscopic and ECD analyses. 3-Oxo-8-hydroxyeremophila-1,7(11)-dien-12,8-olide (6) showed the most inhibitory effect on NO production in LPS-stimulated RAW 264.7 cells with the IC50 value of 6.528 μM. Meanwhile, compound 6 also decreased the mRNA expression of pro-inflammatory factors IFN-γ, IL-1β, IL-6 and TNF-α via downregulating NF-κB signaling pathway in vitro. Furthermore, compound 6 reduced the mortality, murine sepsis score, the serum TNF-α level and organic damage in a mouse model of sepsis. These findings indicated that compound 6 possessed the potent anti-inflammatory activity and had the potential as a promising drug candidate for sepsis therapy.

Abstract
The increasing prevalence of autoimmune diseases globally has prompted extensive research and the development of immunosuppressants. Currently, immunosuppressive drugs such as cyclosporine, rapamycin, and tacrolimus have been utilized in clinical practice. However, long-term use of these drugs may lead to a series of adverse effects. Therefore, there is an urgent need to explore novel drug candidates for treating autoimmune diseases. This review aims to find potential candidate molecules for natural immunosuppressive compounds derived from plants, animals, and fungi over the past decade. These compounds include terpenoids, alkaloids, phenolic compounds, flavonoids, and others. Among them, compounds 49, 151, 173, 200, 204, and 247 have excellent activity; their IC50 were less than 1 μM. A total of 109 compounds have good immunosuppressive activity, with IC50 ranging from 1 to 10 μM. These active compounds have high medicinal potential. The names, sources, structures, immunosuppressive activity, and the structure-activity relationship were summarized and analyzed.

Abstract
Stigma maydis (corn silk) (S. maydis) is a food-based by-product of maize and possesses great nutritional and pharmaceutical value. This study aimed to explore bioactive components from S. maydis. By the guidance of bioactivity-guided approach and Global Natural Products Social (GNPS) molecular networking, 12 terpenoids were discovered from S. maydis. The structures of 11 undescribed compounds (1-11) were determined by detailed spectroscopic analyses, single-crystal X-ray diffraction analysis, specific rotation calculations, electronic circular dichroism (ECD) calculations, and NMR calculations. The neuroprotective and acetylcholinesterase (AChE) inhibitory effects of 1-12 were examined, and most of them showed significant or moderate activities. The underlying neuroprotective mechanism of 4 and 5 was revealed by Hoechst 33258, AO-EB, and JC-1 staining assays. This work illustrated the potential of S. maydis as a prospective natural source of bioactive compounds in food and pharmaceutical industries.

PLANTS (BASEL, SWITZERLAND) 2022; 11:3005.

Abstract
Ligularia fischeri Turcz leaves are widely consumed and have multiple health benefits. We aimed to evaluate the differences in the phytochemical composition and biological properties of the root and leaf extracts from L. fischeri. The root extract exhibited higher antioxidant capacity and total flavonoid levels than the leaf extract. GC/MS analysis revealed the presence of various volatiles, diterpenoids, sesquiterpenes, and other non-polar compounds. Moreover, these extracts enhanced cellular antioxidant defense by reducing the level of reactive oxygen species and upregulating the expression of catalase and heme oxygenase-1 in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. The root and leaf extracts also exerted anti-inflammatory effects by suppressing nitric oxide production and diminishing the levels of inducible nitric oxide synthase, cyclooxygenase-2, and interleukin-1β in LPS-stimulated macrophages. Overall, these findings suggest that L. fischeri root extract contains diverse bioactive compounds for the development of nutraceuticals or functional foods with antioxidant and anti-inflammatory activity.

Abstract
Eight undescribed jatrophane diterpenoids, euphohelinoids A-H, along with 11 known analogues were isolated from the whole plant of Euphorbia heliosocpia L. Among them, euphohelinoids A and B contain a rare type of jatrophane diterpenoid skeleton with a 7,8-seco scaffold. To the best of our knowledge, only two such jatrophane diterpenoids have been reported. In addition, euphohelinoids G and H belong to a rare class of jatrophane diterpene possessing a β-hydroxy group at C-11. Structure elucidation of these undescribed diterpenoids was performed by spectroscopic analysis, including NMR, HRESIMS, IR, electronic circular dichroism (ECD) and DP4+ analysis. The cytotoxicity of 17 abundant jatrophane diterpenes was evaluated against HepG2, HeLa, HL-60, and SMMC-7721 cell lines. Seven compounds presented potent cytotoxicity against the four tested cell lines with IC50 values from 8.1 to 29.7 μM. Moreover, preliminary structure-activity relationships for these jatrophane diterpenoids were discussed.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 99:154006. [PMID: 35299029 DOI: 10.1016/j.phymed.2022.154006] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Revised: 02/06/2022] [Accepted: 02/16/2022] [Indexed: 05/11/2023]
Abstract
BACKGROUND Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by high levels of proinflammatory cytokines and epithelial barrier dysfunction. The root of Ligularia fischeri (Ledeb.) Turcz. is a traditional Chinese medicinal herb with diverse therapeutic properties, which has been successfully used to treat inflammation-related diseases. However, little is known about its effect and mechanism against UC. PURPOSE To investigate the efficacy and mechanism of L. fischeri root extracts against UC. METHODS L. fischeri root samples were prepared using the alcohol extraction method and liquid-liquid extraction method. A dextran sodium sulfate-induced UC mouse model and a lipopolysaccharide (LPS)-induced inflammatory cell model were employed in the present study. Cell apoptosis was detected by TUNEL staining, and an enzyme-linked immunosorbent assay was used to quantify the abundance of inflammatory factors in tissues. Hematoxylin and eosin staining and Masson staining were employed to analyze drug toxicity to the liver and kidney. A myeloperoxidase (MPO) assay kit was used to detect neutrophil infiltration in colon tissues. RT-qPCR was then employed to quantify the transcriptional levels of proinflammatory and apoptotic-related genes, while tight junction and apoptosis-related proteins were quantified via western blotting. Gas Chromatography/Mass Spectrometry analysis was then performed to identify the natural compounds in L. fischeri root extracts. RESULTS The water decoction extract, methanol extract, and especially the chloroform extract (CE) exerted potent therapeutic effects in UC mice. Similar to the positive control group (5-aminosalicylic acid), oral administration of CE (30, 60, and 90 mg/kg/d) elicited distinct therapeutic effects on UC mice in the medium- and high-dose groups. CE decreased disease activity index, histopathological score, and MPO level significantly, and effectively retained the colon length. Furthermore, CE significantly reduced the levels of proinflammatory cytokines, including interleukin (IL)-1β, IL-6, and tumor necrosis factor-α and enhanced the expression of tight junction proteins, such as zonula occludens (ZO)-1, ZO-2, claudin-1, and occludin, as well as the transcriptional levels of mucins, such as MUC-1 and MUC-2, in UC mice. Notably, CE prevented apoptosis of colonic epithelial cells by up-regulating Bcl-2 and down-regulating Bax. Also, CE inhibited the secretion of pro-inflammatory cytokines and apoptosis in LPS-induced RAW264.7 macrophages via the activation of Bcl-2/Bax signals. CONCLUSIONS Collectively, L. fischeri root extracts, especially CE, have obvious therapeutic effects against UC. CE reduces inflammation and protects the intestinal epithelial cells and intestinal epithelial barrier via activation of the Bcl-2/Bax signaling pathway, and may be a promising therapeutic agent for UC treatment.

Structurally diversified ent-kaurane and abietane diterpenoids from the stems of Tripterygium wilfordii and their anti-inflammatory activity. Bioorg Chem 2021; 115:105178. [PMID: 34303897 DOI: 10.1016/j.bioorg.2021.105178] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 06/30/2021] [Accepted: 07/12/2021] [Indexed: 12/20/2022]
Abstract
Four undescribed ent-kaurane diterpenoids, wilkaunoids A - D (1-4), and three undescribed abietane diterpenoids, wilabinoids A - C (13-15), along with thirteen known ones (5-12 and 16-20), were isolated from Tripterygium wilfordii. Their structures were elucidated by extensive spectroscopic methods, electroniccirculardichroism calculation, and X-ray diffraction analysis. Compounds 1 and 2 were a pair of C-19 epimers of ent-kaurane diterpenoids, featuring a rare 19,20-epoxy-19,20-dimethoxy-kaurane fragment. Compound 3 possessed a rare naturally occurring 1,3-dioxacyclohexane moiety. Compounds 13 and 15 represented the first example of abietane diterpenoids with an isovalerate substitution from the genus of Tripterygium. The possible biosynthetic pathways of 1-3 were postulated. The effect of 1-20 on nitric oxide production was examined in lipopolysaccharide-stimulated RAW 264.7 cells. Abietane diterpenoid quinones 7-13 (IC50: 1.9-10.2 μM) exhibited the significant activity to inhibit nitric oxide production versus positive control (NG-monomethyl-l-arginine acetate salt, IC50 = 24.9 μM). The structure activity relationship of 7-13 in inhibiting nitric oxide production was then discussed. The most potent 7 and 8 were found to significantly suppress the expression of cyclooxygenase-2 and inducible nitric oxide synthase proteins, showing a good anti-inflammatory potential. The findings provided some valuable insights for the discovery and structural modification of abietane diterpenoids towards anti-inflammatory lead compounds.

Abstract
A decoction prepared from the aerial parts of Melampodium divaricatum showed antinociceptive and antihyperalgesic responses when tested in the formalin model in mice. From the CH2 Cl2 fraction of the decoction, two non-previously reported secondary metabolites, 3-O-β-D-glucopyranosyl-16α-hydroxy-ent-kaurane (1) and melampodiamide (2) [(2'R*,4'Z)-2'-hydroxy-N-[(2S*,3S*,4R*)-1,3,4-trihydroxyoctadec-2-yl]tetracos-4-enamide] were separated and characterized by spectroscopic, spectrometric, and computational techniques. The flavonoids isoquercitrin and hyperoside, which possessed noted antinociceptive properties, were obtained from the active AcOEt fraction of the decoction. The chemical composition of the essential oil of the plant was also analyzed by gas chromatography-mass spectrometry. The major constituents were (E)-caryophyllene, germacrene D, β-elemene, δ-elemene, γ-patchoulene, and 7-epi-α-selinene. Headspace solid-phase microextraction analysis detected (E)-caryophyllene as the main volatile compound of the plant.

Abstract
Sagittaria trifolia is an aquatic plant that is distributed worldwide. The edible tuber part of S. trifolia is a very common and popular vegetable in China. The aim of the present review is to discuss the discovery of nutraceuticals from S. trifolia tuber by reviewing its major constituents, food processing, food products, and health-promoting benefits. Sagittaria trifolia tuber comprises a series of nutritional and bioactive constituents, including dietary fibers, amino acids, minerals, starches, non-starch polysaccharides, diterpenoids, colchicine, phenols, and organic acids. Food processing affects its flavor, biocomponents, and bioactivity. Numerous S. trifolia tuber-based food products and nutraceuticals have been developed, but new categories of products and the anticipated functions still need to be explored. The non-starch polysaccharides could be the central ingredients that contribute to the plant's antioxidant, hepatoprotective, hypoglycemic, lipid-regulating, and immunostimulatory properties. Of these, antioxidant and hepatoprotective effects have been thoroughly investigated. Procedures for the extraction and purification of polysaccharides influence their health-promoting actions. Overall, S. trifolia tuber is an underutilized aquatic vegetable species that is an emerging subject for nutraceutical research. © 2020 Society of Chemical Industry.

Molecules 2021; 26:molecules26113076. [PMID: 34063939 PMCID: PMC8196580 DOI: 10.3390/molecules26113076] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Revised: 05/18/2021] [Accepted: 05/18/2021] [Indexed: 12/16/2022] Open
Abstract
The current treatments against Leishmania parasites present high toxicity and multiple side effects, which makes the control and elimination of leishmaniasis challenging. Natural products constitute an interesting and diverse chemical space for the identification of new antileishmanial drugs. To identify new drug options, an in-house database of 360 kauranes (tetracyclic diterpenes) was generated, and a combined ligand- and structure-based virtual screening (VS) approach was performed to select potential inhibitors of Leishmania major (Lm) pteridine reductase I (PTR1). The best-ranked kauranes were employed to verify the validity of the VS approach through LmPTR1 enzyme inhibition assay. The half-maximal inhibitory concentration (IC50) values of selected bioactive compounds were examined using the random forest (RF) model (i.e., 2β-hydroxy-menth-6-en-5β-yl ent-kaurenoate (135) and 3α-cinnamoyloxy-ent-kaur-16-en-19-oic acid (302)) were below 10 μM. A compound similar to 302, 3α-p-coumaroyloxy-ent-kaur-16-en-19-oic acid (302a), was also synthesized and showed the highest activity against LmPTR1. Finally, molecular docking calculations and molecular dynamics simulations were performed for the VS-selected, most-active kauranes within the active sites of PTR1 hybrid models, generated from three Leishmania species that are known to cause cutaneous leishmaniasis in the new world (i.e., L. braziliensis, L. panamensis, and L. amazonensis) to explore the targeting potential of these kauranes to other species-dependent variants of this enzyme.

Abstract
More than 100 Ligularia species and those of several related genera (Cremanthodium, Cacalia, Senecio, and others) in the plant family Senecioneae grow in East Asia. For many years, researchers have studied the chemical constituents of these plants, and terpenoids, flavonoids, sterols, alkaloids, and aromatic compounds have been isolated. Among these, in particular, numerous sesquiterpenoids were reported. In this contribution, relevant chemical studies are described mainly from literature reports appearing since 2000, inclusive of investigations performed by the present authors, on the diversity in secondary metabolites of Ligularia growing in the Hengduan Mountains area of China, focusing on eremophilane sesquiterpenoids and other metabolites. Terpenoids and aromatic compounds (totaling 1049), both new and known, are listed. Genetic studies and synthesis investigations are also reviewed briefly.

Abstract
Polycyclic diterpenes exhibit many important biological activities, but de novo synthetic access to these molecules is highly challenging because of their structural complexity. Semisynthetic access has also been limited by the lack of chemical tools for scaffold modifications. We report a chemoenzymatic platform to access highly oxidized diterpenes by a hybrid oxidative approach that strategically combines chemical and enzymatic oxidation methods. This approach allows for selective oxidations of previously inaccessible sites on the parent carbocycles and enables abiotic skeletal rearrangements to additional underlying architectures. We synthesized a total of nine complex natural products with rich oxygenation patterns and skeletal diversity in 10 steps or less from ent-steviol.

Abstract
In this study, we present a new hybrid functional denoted as xOPBE, which is optimized at the 6-311+G(2d,p) basis set and designed with a specific aim of providing accurate 13C chemical shifts. By mixing the Hartree-Fock exchange into the OPBE functional, xOPBE provides a significantly improved overall performance as compared to its parent OPBE functional, while OPBE was shown previously as an excellent functional for 13C chemical shifts. Even in the case of the 1-adamantyl cation, for which OPBE completely fails in reproducing the experimental results, xOPBE still performs very well with similar accuracy as the standard CCSD(T) method with a large basis set. Our results also demonstrate that xOPBE not only can improve quantitatively the description of the correct assignments given by OPBE but also can revert OPBE's incorrect assignments qualitatively. Thus, we would like to recommend the use of xOPBE for routine evaluations of 13C chemical shifts.

Abstract
The screening and testing of extracts against a variety of pharmacological targets in order to benefit from the immense natural chemical diversity is a concern in many laboratories worldwide. And several successes have been recorded in finding new actives in natural products, some of which have become new drugs or new sources of inspiration for drugs. But in view of the vast amount of research on the subject, it is surprising that not more drug candidates were found. In our view, it is fundamental to reflect upon the approaches of such drug discovery programs and the technical processes that are used, along with their inherent difficulties and biases. Based on an extensive survey of recent publications, we discuss the origin and the variety of natural chemical diversity as well as the strategies to having the potential to embrace this diversity. It seemed to us that some of the difficulties of the area could be related with the technical approaches that are used, so the present review begins with synthetizing some of the more used discovery strategies, exemplifying some key points, in order to address some of their limitations. It appears that one of the challenges of natural product-based drug discovery programs should be an easier access to renewable sources of plant-derived products. Maximizing the use of the data together with the exploration of chemical diversity while working on reasonable supply of natural product-based entities could be a way to answer this challenge. We suggested alternative ways to access and explore part of this chemical diversity with in vitro cultures. We also reinforced how important it was organizing and making available this worldwide knowledge in an "inventory" of natural products and their sources. And finally, we focused on strategies based on synthetic biology and syntheses that allow reaching industrial scale supply. Approaches based on the opportunities lying in untapped natural plant chemical diversity are also considered.

Abstract
A considerable amount of bioactive compounds have been used for the biopharmaceutical engineering to help human health and nutrition. Hairy root culture (HRC) or transgenic root is a favourable alternative technique for phytochemical production. Ligularia fischeri is a significant source of pharmaceutically important active compounds with an enormous range of health care applications. HRC of L. fischeri was developed using Agrobacterium rhizogenes for the production of polyphenolic compounds with antioxidant, antimicrobial, antidiabetic, anticancer and anti-inflammatory pharmaceutical activities. Hairy roots (HRs) were selected by morphological assessment, genetic and molecular analyses. The maximum accumulation of fresh mass (94.15 g/L) and dry mass (9.45 g/L) was recorded in MS liquid medium supplemented with 30 g/L sucrose at 28 days. Furthermore, HRs successfully produced numerous polyphenolic compounds, including six hydroxycinnamic acids, seven flavonols, seven hydroxybenzoic acids, vanillin, resveratrol, pyrogallol, homogentisic, and veratric acids, which were identified by UHPLC analysis. HRs produced higher total phenolic (185.65 mg/g), and flavonoid (5.25 mg/g) contents than non-transformed roots (125.55 mg/g and 3.75 mg/g). As a result of these metabolic changes, pharmaceutical activities were found higher in HRs than non-transformed roots (NTRs). The present study indicates that HRC has the potential to increase the content of beneficial polyphenolic compounds with higher potential pharmaceutical activities. To the best of our knowledge, the present study is the first report on enhancing the production of polyphenolic compounds with pharmaceutical activities from the HRCs of L. fischeri.
