Abstract
PTP1B plays an important role as a key negative regulator of tyrosine phosphorylation associated with insulin receptor signaling in the therapy for diabetes and obesity. In this study, the anti-diabetic activity of dianthrone derivatives from Polygonum multiflorum Thunb., as well as the structure-activity relationships, mechanism, and molecular docking were explored. Among these analogs, trans-emodin dianthrone (compound 1) enhances insulin sensitivity by upregulating the insulin signaling pathway in HepG2 cells and displays considerable anti-diabetic activity in db/db mice. By using photoaffinity labeling and mass spectrometry-based proteomics, we discovered that trans-emodin dianthrone (compound 1) may bind to PTP1B allosteric pocket at helix α6/α7, which provides fresh insight into the identification of novel anti-diabetic agents.

Abstract
BACKGROUND Polygonum multiflorum Thunb. (PM) is well known both in China and other countries of the world for its tonic properties, however, it has lost its former glory due to liver toxicity incidents in recent years. PURPOSE The purpose of this study is to determine whether the occurrence of herb-drug interaction (HDI) caused by PM is associated with cytochrome P450 (CYP450) based on pharmacokinetic studies and in vitro inhibition assays. The objective was to provide a reference for the rational and safe use of drugs in clinical practice. METHODS In this study, raw PM (R), together with its two processed products which included PM by Chinese Pharmacopoeia (M) and PM by "nine cycles of steaming and sunning (NCSS)" ("9"), were prepared as the main research objects. A method based on fluorescence technology was used to evaluate the inhibition levels of raw and processed PMs, as well as corresponding characteristic compounds on seven recombinant human cytochrome P450s (rhCYP450s). The pharmacokinetics of sulindac (a representative of commonly used nonsteroidal anti-inflammatory drugs) and psoralen (a major compound of Psoralea in combination with PM) in rat plasma were studied when combined with raw and different processed products of PM. RESULTS The inhibitory level order of the three extracts on major different subtypes of CYP450 (CYP1A2, CYP2B6, CYP2C8, CYP2C19, CYP2D6, and CYP3A4) was: R > M > "9". However, the inhibition level of R and "9" is higher than that of M on CYP2C9. Further studies showed that trans-THSG and emodin could selectively inhibit CYP3A4 and CYP1A2, respectively. Epicatechin gallate mainly inhibited CYP3A4 and CYP1A2, followed by CYP2C8 and CYP2C9. Genistein mainly inhibited CYP3A4, followed by CYP2C9 and CYP2C8. CYP3A4 and CYP2C9 were also inhibited by daidzein. The inhibitory effects of all the PM extracts were associated with their characteristic compounds. The results of HDI showed that R increased sulindac exposure to rat blood, and R and M increased psoralen exposure to rat blood, which were consistent with corresponding metabolic enzymes. Overall, the in vitro and in vivo results indicated that PM, especially R, would be at high risk to cause toxicity and drug interactions via CYP450 inhibition. CONCLUSION This study not only elucidates the scientific connotation of "efficiency enhancement and toxicity reduction" of PM by NCSS from the perspective of metabolic inhibition but also contributes to HDI prediction and appropriate clinical medication of PM.

Abstract
A vast array of plant-based compounds has enriched red biotechnology to serve the human health and food. A peculiar medicinal plant which was an element of traditional Chinese medicine for centuries as a liver and kidney tonic, for life longevity and hair blackening, is Polygonum multiflorum Thunb. (PM) which is popularly known as "He shou wu" or "Fo-ti" and is rich in chemical components like stilbenes, quinones, and flavonoids which have been used as anti-aging, anti-alopecia, anti-cancer, anti-oxidative, anti-bacterial, anti-hyperlipidemia, anti-atherosclerosis, and immunomodulating and hepatoprotective agents in the modern medicine. The health benefits from PM are attained since long through commercial products such as PM root powder, extract, capsules, tincture, shampoo, and body sprays in the market. Currently, the production of these pharmaceuticals and functional foods possessing stilbenes, quinones, and flavonoids is through cell and organ cultures to meet the commercial demand. However, hepatotoxic effects of PM-based products are the stumbling blocks for its long-term usage. The current review encompasses a comprehensive account of bioactive compounds of PM roots, their biological activities as well as efficacy and toxicity issues of PM ingredients and future perspectives.

Abstract
In commercial herbal markets, Polygoni Multiflori Radix (PMR, the tuberous roots of Polygonum multiflorum Thunb.), a commonly-used Chinese medicinal material, is divided into different grades based on morphological features of size and weight. While more weight and larger size command a higher price, there is no scientific data confirming that the more expensive roots are in fact of better quality. To assess the inherent quality of various grades and of various tissues in PMR and to find reliable morphological indicators of quality, a method combining laser microdissection (LMD) and ultra-performance liquid chromatography triple-quadrupole mass spectrometry (UPLC-QqQ-MS/MS) was applied. Twelve major chemical components were quantitatively determined in both whole material and different tissues of PMR. Determination of the whole material revealed that traditional commercial grades based on size and weight of PRM did not correspond to any significant differences in chemical content. Instead, tissue-specific analysis indicated that the morphological features could be linked with quality in a new way. That is, PMR with broader cork and phloem, as seen in a transverse section, were typically of better quality as these parts are where the bioactive components accumulate. The tissue-specific analysis of secondary metabolites creates a reliable morphological criterion for quality grading of PMR.

Abstract
The THSG biosynthetic pathway in F. multiflora was characterized, and enzymatic activities responsible for the resveratrol synthesis, hydroxylation, and glycosylation reactions involved in THSG biosynthesis were confirmed in vitro. The biosynthetic origin of 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucopyranoside (THSG) and the enzymes involved in THSG biosynthesis in Fallopia multiflora were studied using stable isotope labeling and biocatalytic methods. UPLC-MS-based analyses were used to unravel the isotopologue composition of the biosynthetic intermediates and products, as well as to detect the products of the enzyme assay experiments. In this study, 13C-labeled L-phenylalanine (L-PHE), sodium pyruvate (SP), and sodium bicarbonate (SB) were used as putative precursors in the feeding experiment. Labeling of polydatin (PD) and THSG using [13C9]L-PHE and [13C1]L-PHE confirmed that the p-coumaric moiety of PD and THSG was derived from PHE. The results of the feeding experiments with [13C] SB and [2, 3-13C2] SP suggested that PD and THSG were derivatives of resveratrol that were synthesized by glycosylation and hydroxylation. We developed methods using total crude protein extracts (soluble and microsomal) for comprehensive and simultaneous analysis of resveratrol synthase, glycosyltransferase, and hydroxylase activities in various tissue types of wild F. multiflora and callus cultures. The activity of each tested enzyme was confirmed in one or more tissue types or cell cultures in vitro. The results of the enzyme activity experiments and the distributions of PD and THSG were used to determine the main site and pathway of THSG biosynthesis in F. multiflora.

Abstract
Anthraquinones (AQs) and phenolic compounds are important phytochemicals that are biosynthesized in cell suspension cultures of Polygonum multiflorum. We wanted to optimize the effects of plant growth regulators (PGRs), media, sucrose, l-glutamine, jasmonic acid (JA), and salicylic acid (SA) for the production of phytochemicals and biomass accumulation in a cell suspension culture of P. multiflorum. The medium containing Murashige and Skoog (MS) salts and 4% sucrose supplemented with 1 mg/L 2,4-dichlorophenoxyacetic acid, 0.5 mg/L thidiazuron, and 100 µM l-glutamine at 28 days of cell suspension culture was suitable for biomass accumulation and AQ production. Maximum biomass accumulation (12.5 and 12.35 g fresh mass (FM); 3 and 2.93 g dry mass (DM)) and AQ production (emodin 295.20 and 282 mg/g DM; physcion 421.55 and 410.25 mg/g DM) were observed using 100 µM JA and SA, respectively. JA- and SA-elicited cell cultures showed several-fold higher biomass accumulation and AQ production than the control cell cultures. Furthermore, the cell suspension cultures effectively produced 23 phenolic compounds, such as flavonols and hydroxycinnamic and hydroxybenzoic acid derivatives. PGR-, JA-, and SA-elicited cell cultures produced a higher amount of AQs and phenolic compounds. Because of these metabolic changes, the antioxidant, antimicrobial, and anticancer activities were high in the PGR-, JA-, and SA-elicited cell cultures. The results showed that the elicitors (JA and SA) induced the enhancement of biomass accumulation and phytochemical (AQs and phenolic compounds) production as well as biological activities in the cell suspension cultures of P. multiflorum. This optimized protocol can be developed for large-scale biomass accumulation and production of phytochemicals (AQs and phenolic compounds) from cell suspension cultures, and the phytochemicals can be used for various biological activities.
