UV-guided isolation of enantiomeric polyacetylenes from Bupleurum scorzonerifolium Willd. with inhibitory effects against LPS-induced NO release in BV-2 microglial cells. Bioorg Chem 2021; 119:105521. [PMID: 34871788 DOI: 10.1016/j.bioorg.2021.105521] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Revised: 11/23/2021] [Accepted: 11/24/2021] [Indexed: 11/24/2022]
Abstract
UV-guided fractionation led to the isolation of thirteen new polyacetylenes (1-13) from the roots of Bupleurum scorzonerifolium Willd. All polyacetylenes were analyzed as racemates since the lack of optical activity and Cotton effects in the ECD spectra. The sequent chiral-phase HPLC resolution successfully gave twelve pairs of enantiomers 1a/1b and 3a/3b-13a/13b. Their structures were elucidated based on the HRESIMS and NMR data analyses. The absolute configurations were determined by the combination of Snatzke's method, electronic circular dichroism calculations, and single-crystal X-ray diffraction. Using Griess methods and MTT assays, polyacetylenes 1a, 3a, 4a/4b-12a/12b, and 13a displayed inhibitory activities against LPS-induced NO release in BV-2 microglial cells.

Abstract
We identified IAA13 negatively associated with lateral root number by comparing the differential expressed genes between Bupleurum chinense and B. scorzonerifolium. Dried roots of the genus Bupleurum L. are used as a herbal medicine for diseases in Asia. Bupleurum chinense has a greater number of lateral roots than B. scorzonerifolium, but the genetic mechanisms for such differences are largely unknown. We (a) compared the transcriptome profiles of the two species and (b) identified a subset of candidate genes involved in auxin signal transduction and explored their functions in lateral root development. By isoform sequencing (Iso-Seq) analyses of the whole plant, more unigenes were found in B. scorzonerifolium (118,868) than in B. chinense (93,485). Given the overarching role of indole-3-acetic acid (IAA) as one of the major regulators of lateral root development, we identified 539 unigenes associated with auxin signal transduction. Fourteen and 44 unigenes in the pathway were differentially expressed in B. chinense and B. scorzonerifolium, respectively, and 3 unigenes (LAX2, LAX4, and IAA13) were expressed in both species. The number of lateral root primordia increased after exogenous auxin application at 8 h and 12 h in B. scorzonerifolium and B. chinense, respectively. Since overexpression of IAA13 in Arabidopsis reduced the number of lateral roots, we hypothesized that IAA13 is involved in the reduction of the number of lateral roots in B. scorzonerifolium.

Bioactive C 17 and C 18 Acetylenic Oxylipins from Terrestrial Plants as Potential Lead Compounds for Anticancer Drug Development. Molecules 2020; 25:molecules25112568.

Abstract
Bioactive C17 and C18 acetylenic oxylipins have shown to contribute to the cytotoxic, anti-inflammatory, and potential anticancer properties of terrestrial plants. These acetylenic oxylipins are widely distributed in plants belonging to the families Apiaceae, Araliaceae, and Asteraceae, and have shown to induce cell cycle arrest and/or apoptosis of cancer cells in vitro and to exert a chemopreventive effect on cancer development in vivo. The triple bond functionality of these oxylipins transform them into highly alkylating compounds being reactive to proteins and other biomolecules. This enables them to induce the formation of anti-inflammatory and cytoprotective phase 2 enzymes via activation of the Keap1–Nrf2 signaling pathway, inhibition of proinflammatory peptides and proteins, and/or induction of endoplasmic reticulum stress, which, to some extent, may explain their chemopreventive effects. In addition, these acetylenic oxylipins have shown to act as ligands for the nuclear receptor PPARγ, which play a central role in growth, differentiation, and apoptosis of cancer cells. Bioactive C17 and C18 acetylenic oxylipins appear, therefore, to constitute a group of promising lead compounds for the development of anticancer drugs. In this review, the cytotoxic, anti-inflammatory and anticancer effects of C17 and C18 acetylenic oxylipins from terrestrial plants are presented and their possible mechanisms of action and structural requirements for optimal cytotoxicity are discussed.

Abstract
In the search for biologically active compounds from the roots of Bupleurum chinense D C., phytochemical investigation of its ethanol extract led to the isolation and identification of a new 8-O-4' neolignan glucoside, saikolignanoside A (1), along with eight known lignans (2-9). Their structures were determined on the basis of IR, UV, HRESIMS, and NMR spectroscopic analyses. The antioxidant and cytotoxic effects of isolated compounds were evaluated in vitro. The isolated compounds (IC50 > 200 μM) did not display 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. Whereas compounds 1-2, 5, 7, and 9 exhibited potent 2, 2'-azinobis(3-ethyl-benzothiazoline-6-sulfonic acid) (ABTS) free radical scavenging properties with IC50 values ranging from 8.34 to 15.24 μM, while compounds 3-4, 6, 8 showed moderate properties. In addition, all compounds were evaluated for cytotoxicities against A549, HepG2, U251, Bcap-37, and MCF-7 cell lines. Compounds 5 and 9 (IC50 < 51.62 μM) possessed stronger cytotoxic activities against all the tested tumor cell lines, compared with the positive control 5-Fluorouracil.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The genus Bupleurum includes approximately 200 species that are widely distributed in the Northern Hemisphere, Eurasia and North Africa. Certain species of this genus have long been used as antiphlogistic, antipyretic and analgesic agents in traditional folk medicine. As described in the Chinese Pharmacopoeia, the roots of Bupleurum chinense DC. and B. scorzonerifolium Willd. are the herbal materials that compose Chaihu (Radix Bupleuri), a well-known TCM herb. AIM OF THE REVIEW This review aims to provide up-to-date and comprehensive information regarding the distribution, toxicity, molecular mechanism and relatively new methods for the qualitative and quantitative determination of polyacetylenes in different Bupleurum species. METHOD The information needed for this paper were sourced from publishing sites such as Elsevier, science Direct, PubMed; electronic search engines such as Scopus and Web of Science, Google scholar; other scientific database sites for chemicals such as ChemSpider, PubChem, SciFinder, and also from on line books. RESULTS Polyacetylenes, which are widely distributed in genus Bupleurum of the Apiaceae family, have high toxicity. Among polyacetylenes, bupleurotoxin, acetylbupleurotoxin and oenanthotoxin have strong neurotoxicity. Through previous research, it was found that the toxicity of Bupleurum polyacetylenes manifested as epileptic seizures, with the target of toxicity being the brain. The neurotoxicity of polyacetylenes exhibits a relationship with the γ-aminobutyric acid (GABA) receptor pathway, and polyacetylenes have been shown to inhibit GABA-induced currents (IGABA) in a competitive manner. CONCLUSIONS The plants of genus Bupleurum have been used in traditional medicine for thousands of years. However, certain species of this genus are poisonous, and it was attributed to the high content of polyacetylenes. The present review indicates that certain polyacetylenes in the genus Bupleurum have highly neurotoxic effects. The major challenge with regard to toxic polyacetylenes is to test their neurotoxic effects in vivo as well as in further preclinical studies, which will require large amounts of purified polyacetylenes. More reference substances should be prepared, and sophisticated analytical technologies should be developed to comprehensively assess the quality of Radix Bupleuri herbs. These investigations will be helpful for further utilization of the plants of genus Bupleurum.

Abstract
Four new acetylenes (1–4) and one new unsaturated ω-hydroxy fatty acid (5), together with 5 known analogues, were isolated from an aqueous extract of Codonopsis pilosula roots. Their structures were determined by spectroscopic and chemical methods. The new acetylenes are categorized as an unusual cyclotetradecatrienynone (1), tetradecenynetriol (2), and rare octenynoic acids (3 and 4), respectively, and 3 and 4 are possibly derived from oxidative metabolic degradation of 1 and/or 2. The absolute configuration of 1 was assigned by comparison of the experimental circular dichroism (CD) spectrum with the calculated electronic circular dichroism (ECD) spectra of stereoisomers based on the quantum-mechanical time-dependent density functional theory, while the configuration of 2 was assigned by using modified Mosher׳s method based on the MPA determination rule of ΔδRS values for diols.

Abstract
This study was carried out to identify some new antidepressant compounds present in Radix Bupleuri (RB) and to develop a method for their quantitative analysis in rat serum for the first time. Four polyacetylenes, including two new compounds, were isolated from Bupleurum scorzonerifoliu and identified. An in vitro uptake study using rat synaptosomes showed that the polyacetylenes potently inhibited serotonin, norepinephrine and dopamine reuptake, and exhibited an antidepressant activity with a potency comparable with or better than their corresponding specific inhibitors. An ultra-performance liquid chromatography coupled with photodiode array detector (UPLC-PDA) method was developed for their quantitative analysis in rat serum. The analysis was performed on a Waters BEH C18 column (1.7 μm, 100 × 2.1 mm i.d.) using a gradient system of acetonitrile and 0.03% trifluoroacetic acid water, with a detector wavelength of 315 nm. Only two polyacetylenes, ((2 Z,8 E,10 E)-pentadecatriene-4,6-diyn-1-ol (RB-2) and bupleurynol (RB-4)), were detected in the primarily pharmacokinetic study of the petroleum ether fraction of RB. Both were rapidly absorbed and slowly eliminated. The rat exposure was approximately linear under the studied dosages ranging from 22.5 to 90 g/kg herb. In summary, polyacetylenes appear to be the key components responsible for the antidepressant activity of RB, and could be used as chemical standards for the quality evaluation of RB.

Abstract
Cirsium japonicum var. australe, used as a folk medicine in Taiwan, has been employed traditionally in the treatment of diabetes and inflammatory symptoms. Bioactivity-guided fractionation of its ethanolic extract, utilizing centrifugal partition chromatography monitored by DPPH-TLC analysis, led to the isolation of three new acetylenic phenylacrylic acid esters (1-3) and two new polyacetylenes (4 and 5), together with seven known compounds (6-12). The structures of 1-5 were elucidated by spectroscopic methods including 1D and 2D NMR techniques. The absolute configurations of 4 and 7 were determined utilizing Mosher's method and ECD/CD experiments. The DPPH scavenging activity of the constituents isolated from the C. japonicum var. australe ethanolic extract was evaluated. The potential antidiabetic activity of some of the isolates was evaluated using in vitro cellular glucose uptake and oil red staining assays.

Abstract
Many species of genus Bupleurum L. have been pharmaceutically used mainly in Asia and Europe for thousand years. Their roots are the most popular ingredients in Chinese materia medica prescriptions for the treatment of inflammatory diseases and auto-immune diseases. A plenty of chemical constituents have been isolated and identified from the species in Bupleurum L., such as saikosaponins, polysaccharides, volatile oils, flavonoids, polyacetylenes, lignins, and coumarins, most of which possess a variety of biological activities, especially for the hepatoprotective effect, antitumor activity, immunoregulation, and febrifuge efficacy. Therefore, the species in genus Bupleurum L. could be potential herbs of immunomodulator, antineoplastic, anti-oxidant, etc. Meanwhile, as potential toxicities have been discovered in some constituents, it is urgent to establish a comprehensive quality evaluation system to ensure the safety and efficiency of herbs. This paper reviews on the phytochemical and pharmacological studies, especially for the toxicology and quality control of the species in Bupleurum L., which is a reference for the species in this genus for safe usage and further development.

Abstract
African trypanosomiasis is still a major health problem in many sub-Saharan countries in Africa. We investigated the effects of three preparations of Panax ginseng, Panax notoginseng, isolated ginsenosides, and the polyacetylene panaxynol on Trypanosoma brucei brucei and the human cancer cell line HeLa. Hexane extracts and the pure panaxynol were toxic and at the same time highly selective against T. b. brucei, whereas methanol extracts and 12 isolated ginsenosides were significantly less toxic and showed only weak selectivity. Panaxynol was cytotoxic against T. b. brucei at the concentration of 0.01 µg/mL with a selectivity index of 858, superior even to established antitrypanosomal drugs. We suggest that the inhibition of trypanothione reductase, which is only found in trypanosomes, might explain the observed selectivity. The high selectivity together with a cytotoxic concentration in the range of the bioavailability makes panaxynol and other polyacetylenes in general very promising lead compounds for the treatment of African trypanosomiasis.

Qualitative and quantitative determination of polyacetylenes in different Bupleurum species by high performance liquid chromatography with diode array detector and mass spectrometry.

Abstract
Polyacetylenes are main toxic ingredients in Bupleurum longiradiatum, a poisonous plant that has ever been misused as substitutes for Chaihu (Bupleuri Radix). For the first time, a high-performance liquid chromatography method coupled with diode array detector and mass spectrometry (HPLC-DAD-MS) was developed for qualitative and quantitative analysis of nine polyacetylenes in Bupleurum species. All references, including two new polyacetylenes, were isolated from B. longiradiatum and purified using a semi-preparation HPLC chromatography. The analysis was performed on a TSKgel ODS-100V C18 column (3 μm, 150 mm x 4.6 mm i.d.) using a gradient system of acetonitrile and water, with diode array detection (254 nm). The method was validated for linearity, precision, accuracy, limit of detection and quantification. A total of 27 Bupleurum samples were examined with this method, which showed a great variety in the distribution and contents of the polyacetylenes. It was found that polyacetylenes (1-8) were the main ingredients in B. longiradiatum, while a few kinds of polyacetylenes (5-8) were also identified in B. smithii, B. smithii var. parvifolium, B. bicaule and B. angustissimum. However, no polyacetylenes (1-9) were detected in the authentic Chaihu samples and the other Bupleurum species. The results indicated that the toxic B. longiradiatum could readily be distinguished from other medicinal Bupleurum species based on the polyacetylene profiles, and the guidelines and quality control of polyacetylenes for Chaihu are useful. The acute toxicity of the ethanol extract of B. longiradiatum and its fractions was also investigated.
