Abstract
The yellow colour of ornamental varieties of tree peony originated from Paeonia delavayi. However, but P. delavayi and Paeonia suffruticosa belong to different subgroups, so hybridization is difficult and results in a long breeding cycle. However, no comprehensive transcriptomic profiling has focused on the colour formation mechanisms of yellow tree peony petals. Analysing the colour formation mechanism of yellow petals in P. delavayi is very important for directional molecular breeding. In this study, the transcriptional map of yellow pigment development in petals was used to analyse the mechanism of petal colour formation. We analysed the genes related to the metabolism of flavonoids and carotenoids and the transcription factors (TFs) involved in P. delavayi var. lutea (pure yellow individual) yellow pigment development using transcriptome sequence profiling. Transcriptome sequence profiles revealed three and four differentially expressed transcripts (DETs) involved in flavonoid biosynthesis and carotenoid biosynthesis, respectively. An analysis of DETs in the flavonoid pathway showed that chalcone synthase (CHS) and chalcone 2´-glucosyltransferases (THC2'GT) act in synergy to synthesize isosalipurposide (ISP). CHS and flavonol synthase (FLS) synergistically synthesize quercetin and kaempferol. DEG analysis of the carotenoid pathway revealed that phytoene synthase (PSY), carotenoid isomerase (CRTISO) and β-carotene hydroxylases (CHYB) play a key role in regulating lutein formation, and carotenoid cleavage dioxygenase (CCD) plays an important role in the degradation of carotenoids. These two pathways may be regulated by TF families such as bHLH, ARF, and MYB. The results of the transient overexpression of genes showed that CHS and CHI are regulated by PdMYB2. In this study, the molecular mechanism of ISP synthesis was analysed in depth, and the complete metabolic pathway of carotenoids in Paeonia L. was reported for the first time. By studying the formation mechanism of yellow pigment in P. delavayi petals, a breeding strategy for improving flavonol and carotenoid contents and reducing anthocyanin synthesis by genetic engineering was suggested.

Sequence Analysis and Functional Verification of the Effects of Three Key Structural Genes, PdTHC2'GT, PdCHS and PdCHI, on the Isosalipurposide Synthesis Pathway in Paeonia delavayi var. lutea. Int J Mol Sci 2022; 23:5696. [PMID: 35628506 PMCID: PMC9147737 DOI: 10.3390/ijms23105696] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 05/09/2022] [Accepted: 05/18/2022] [Indexed: 01/05/2023] Open
Abstract
Isosalipurposide (ISP) is the most important yellow pigment in tree peony. In ISP biosynthesis, CHS catalyzes 1-molecule coumaroyl-CoA and 3-molecule malonyl-CoA to form 2',4',6',4-tetrahyroxychalcone (THC), and THC generates a stable ISP in the vacuole under the action of chalcone2'-glucosyltransferases (THC2'GT). In tree peony, the details of the THC2'GT gene have not yet been reported. In this study, the candidate THC2'GT gene (PdTHC2'GT) in Paeonia delavayi var. lutea was screened. At the same time, we selected the upstream CHS gene (PdCHS) and the competitive CHI gene (PdCHI) to study the biosynthesis pathway of ISP. We successfully cloned three genes and sequenced them; subcellular localization showed that the three genes were located in the nucleus and cytoplasm. The overexpression of PdTHC2'GT in tobacco caused the accumulation of ISP in tobacco petals, which indicated that PdTHC2'GT was the key structural gene in the synthesis of ISP. After the overexpression of PdCHS and PdCHI in tobacco, the accumulation of anthocyanins in tobacco petals increased to different degrees, showing the role of PdCHS and PdCHI in anthocyanin accumulation. The analysis of NtCHS and NtCHI of transgenic tobacco lines by qRT-PCR showed that the THC2'GT gene could increase the expression of CHS. THC2'GT and CHI were found to be competitive; hence, the overexpression of THC2'GT could lead to a decrease in CHI expression. The CHS gene and CHI gene could increase the expression of each other. In conclusion, we verified the key structural gene PdTHC2'GT and studied the operation of the genes in its upstream and competitive pathway, providing a new perspective for the biosynthesis of ISP and new candidate genes for the directional breeding of tree peony.

Abstract
Stilbenes are some of the important phenolic compounds originating from plant families like Vitaceae, Leguminaceae, Gnetaceae, and Dipterocarpaceae. Structurally, they have a C6-C2-C6 skeleton, usually with two isomeric forms. Stilbenes are biosynthesized due to biotic and abiotic stresses such as microbial infections, high temperatures, and oxidation. This review aims to provide a comprehensive overview of stilbenes' botanical sources, chemistry, biosynthetic pathways, pharmacology, and clinical applications and challenges based on up-to-date data. All included studies were collected from PubMed, ScienceDirect, Google Scholar, and CNKI, and the presented data from these indexed studies were analyzed and summarized. A total of 459 natural stilbene compounds from 45 plant families and 196 plant species were identified. Pharmacological studies also show that stilbenes have various activities such as anticancer, antimicrobial, antioxidant, anti-inflammatory, anti-degenerative diseases, anti-diabetic, neuroprotective, anti-aging, and cardioprotective effects. Stilbene synthase (STS) is the key enzyme involved in stilbene biosynthetic pathways. Studies on the therapeutic application of stilbenes pinpoint that challenges such as low bioavailability and isomerization are the major bottlenecks for their development as therapeutic drugs. Although the medicinal uses of several stilbenes have been demonstrated in vivo and in vitro, studies on the development of stilbenes deserve more attention in the future.

Abstract
Phytochemical profiling was undertaken on the crude extracts of the bulbs, stems, and the fruits of Haemodorum brevisepalum, to determine the nature of the chemical constituents present. This represents the first study to investigate the fruits of a species of Haemodorum. In total, 13 new and 17 previously reported compounds were isolated and identified. The new compounds were of the phenylphenalenone-type class, with a representative of a novel structural form, named tentatively "oxabenzochromenone" (1), a compound akin to an intermediate in a recently proposed phenylphenalenone metabolic network (2), seven new phenylphenalenones (4-10), four new phenylbenzoisochromenones (11-14), and a new phenylbenzoisochromenone derivative (18). The previously reported compounds identified were of the following structure classes: oxabenzochrysenone (3, 23-26), flavonol (15, 16), phenylbenzoisochromenone (17, 21, 22, 27-30), and phenylphenalenone (19, 20). Compounds 2-4, 6-9, 15-18, 21, 22, and 26 were subjected to antimicrobial evaluation with moderate activity observed against Staphylococcus aureus MRSA and slight activity against Pseudomonas aeruginosa and Candida albicans. Compounds 4, 6-9, 17, and 21 were also evaluated for anthelminthic activity against larvae of the blood-feeding parasitic nematode Haemonchus contortus.

Abstract
A facile and efficient synthesis of 7-iodobenzo[b]furan derivatives via a highly regioselective tandem α-arylation/intramolecular O-arylation of 5-substituted-1,2,3-triiodobenzenes and benzylketones is described. Remarkably, the α-arylation coupling reactions initiate exclusively at the least sterically-hindered position of the triiodoarene, which results in a highly chemoselective transformation. The highest yields were observed in reactions between electron-poor 1,2,3-triiodoarenes and electron-rich benzylketones, yet the optimized reaction conditions were found to be tolerant to a wide range of different functional groups. This unprecedent synthesis of 7-iodobenzo[b]furans from 1,2,3-triiodobenzenes is scalable, general in scope, and provides easy access to valuable precursors for other chemical transformations.

Abstract
Eight secondary metabolites (1 to 8) were isolated from a marine sponge, a marine alga and three terrestrial plants collected in Australia and subsequently chemically characterised. Here, these natural product-derived compounds were screened for in vitro-anthelmintic activity against the larvae and adult stages of Haemonchus contortus (barber's pole worm)-a highly pathogenic parasitic nematode of ruminants. Using an optimised, whole-organism screening system, compounds were tested on exsheathed third-stage larvae (xL3s) and fourth-stage larvae (L4s). Anthelmintic activity was initially evaluated on these stages based on the inhibition of motility, development and/or changes in morphology (phenotype). We identified two compounds, 6-undecylsalicylic acid (3) and 6-tridecylsalicylic acid (4) isolated from the marine brown alga, Caulocystis cephalornithos, with inhibitory effects on xL3 and L4 motility and larval development, and the induction of a "skinny-straight" phenotype. Subsequent testing showed that these two compounds had an acute nematocidal effect (within 1-12 h) on adult males and females of H. contortus. Ultrastructural analysis of adult worms treated with compound 4 revealed significant damage to subcuticular musculature and associated tissues and cellular organelles including mitochondria. In conclusion, the present study has discovered two algal compounds possessing acute anthelmintic effects and with potential for hit-to-lead progression. Future work should focus on undertaking a structure-activity relationship study and on elucidating the mode(s) of action of optimised compounds.

Abstract
Bacterial infections continue to threaten humankind and the rapid spread of antibiotic resistant bacteria is alarming. Current antibiotics target essential bacterial processes and thereby apply a strong selective pressure on pathogenic and non-pathogenic bacteria alike. One alternative strategy is to block bacterial virulence systems that are essential for the ability to cause disease but not for general bacterial viability. We have previously show that the plant natural product (-)-hopeaphenol blocks the type III secretion system (T3SS) in the Gram-negative pathogens Yersinia pseudotuberculosis and Pseudomonas aeruginosa. (-)-Hopeaphenol is a resveratrol tetramer and in the present study we explore various resveratrol dimers, including partial structures of (-)-hopeaphenol, as T3SS inhibitors. To allow rapid and efficient assessment of T3SS inhibition in P. aeruginosa, we developed a new screening method by using a green fluorescent protein reporter under the control of the ExoS promoter. Using a panel of assays we showed that compounds with a benzofuran core structure i.e. viniferifuran, dehydroampelopsin B, anigopreissin A, dehydro-δ-viniferin and resveratrol-piceatannol hybrid displayed significant to moderate activities towards the T3SS in Y. pseudotuberculosis and P. aeruginosa.

Abstract
Three new acenaphthene derivatives cis-3-(4'-methoxyphenyl)-acenaphthene-1, 2-diol (1), trans-(1S, 2S)-3-phenyl-acenaphthene-1, 2-diol (2) and 8-(4-hydroxyphenyl)-2H-acenaphthylen-1-one (3) in company with six known compounds were isolated from the 70% ethanol extract of the rhizomes of Musa basjoo. Those chemical constituents were separated and purified by macroreticular resin, silica gel, Toyopearl HW-40F, SephadexLH-20 and other chromatographic methods, respectively. The chemical structures of new compounds were elucidated by HR-ESI-MS, 1H NMR, 13C NMR, HMQC, HMBC spectrum and specific optical rotations. Compound 4 was isolated for the first time from the genus Musa and compound 7 was firstly assigned the carbon spectrum. Furthermore, the cytotoxic activity of compounds 1-9 against WM9, MDA-MB231, HeLa, K562, DU145 and PC3 was screened with cisplatin as a positive control. Compound 9 showed promising cytotoxic activities with IC50 values of 2.65 ± 0.38 µM against the HeLa cell lines, while compound 8 possessed significant cytotoxicity with IC50 values of 6.51 ± 0.44, 18.54 ± 0.68 and 7.98 ± 1.44 µM against the HeLa, MDA-MB231 and WM9 cell lines, respectively.

Abstract
We demonstrate the versatile use of the cyclopropylmethyl group to protect phenols through the total synthesis of two benzofuran-based natural products, that is, anigopreissin A and the resveratrol-piceatannol hybrid. This protecting group is a good alternative to the conventional methyl group, owing to the feasibility of introduction, stability under a variety of conditions, and its relative ease of removal under different acidic conditions.

Abstract
The iridium(III)/copper(II)-catalyzed dehydrogenative coupling of salicylaldehydes with internal alkynes proceeds efficiently under atmospheric oxygen through aldehyde C-H bond cleavage and decarbonylation. A variety of benzofuran derivatives can be synthesized by the environmentally benign procedure. DFT calculations suggest that this unique transformation involves the facile deinsertion of CO in the key metallacycle intermediate, which is in marked contrast to the corresponding rhodium(III) catalysis that leads to CO-retentive chromone derivatives.

Abstract
Phytochemical studies of two Australian Anigozanthos (kangaroo paw) species, A. rufus and A. pulcherrimus, resulted in the identification of 13 secondary metabolites. 2-Amino-6-O-p-coumarylheptanedioic acid (3) and chalcone-5'-O-(4-O-p-coumaryl)-O-β-d-glucopyranoside (12) are reported as new compounds and are accompanied by nine flavonoids (2, 5-11, 13) and two anthocyanins (1, 4). Compounds 1 and 4 were isolated as red solids from A. rufus and are likely responsible for the coloration of the flowers. Compounds 1, 3, and 6 showed weak antimicrobial activities against Acinetobacter baumannii ATCC 19606 at concentrations of 52.4, 94.9, and 53.9 μM, respectively.

Abstract
A series of isomeric phenylphenalenones in which the phenyl ring is located at all possible peripheral positions of the phenalenone nuclei was synthesized. The structural characteristics of the series, in which topological variation is permitted with minimal electronic disturbance, could, in principle, allow for easy pharmacophore recognition when the compounds are aligned in steroidomimetic conformations.

Abstract
The structure of fuliginone was revised from a phenyl substituted phenalenone to a hydroxyl substituted phenalenone as a result of its re-purification via HPLC with subsequent NMR analysis together with an independent synthesis and analysis of the crystal structure, which was secured via the crystalline sponge method. On-flow High Performance Liquid Chromatography coupled to Nuclear Magnetic Resonance spectroscopy (HPLC-NMR) was employed to confirm the presence of the natural product in the plant extract and to monitor for any possible degradation or conversion of the compound.

Abstract
Resveratrol-based natural products constitute a valuable source of unique compounds with diverse biological activities. In this report we investigate demethylation strategies to minimize formation of cyclized and dimerized products during the synthesis of viniferifuran and analogues. We found that boron trichloride/tetra-n-butylammonium iodide (BCl3/TBAI) is typically more effective than boron tribromide (BBr3). Based on these findings we carried out the first syntheses of dehydro-δ-viniferin, resveratrol-piceatannol hybrid and anigopreissin A. In addition, we have developed a short and efficient route to viniferifuran that was obtained in 13% yield over six steps.

Abstract
2-Hydroxy-8-(4-hydroxyphenyl)-1H-phenalen-1-one (1), the first reported 8-phenylphenalenone from the roots of Eichhornia crassipes (water hyacinth), was synthesized starting from 2-methoxynaphthalene in 11 steps and with an overall yield of 2%. A cascade Friedel-Crafts/Michael annulation reaction between acryloyl chloride and 2-methoxynaphthalene afforded 9-methoxyperinaphthanone that, after transformation to 9-methoxy-2-(4-methoxyphenyl)-1H-phenalen-1-one by means of standard Suzuki-Miyaura methodology, was subjected to a reductive carbonyl transposition to afford 8-(4-methoxyphenyl)perinaphthanone. Dehydrogenation, epoxidation, and demethylation of the latter afforded 1.
