[PMID: 37845080 DOI: 10.1124/pharmrev.123.000863] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 08/07/2023] [Accepted: 09/29/2023] [Indexed: 10/18/2023] Open
Abstract
Antimicrobial resistance presents us with a potential global crisis as it undermines the abilities of conventional antibiotics to combat pathogenic microbes. The history of antimicrobial agents is replete with examples of scaffolds containing halogens. In this review, we discuss the impacts of halogen atoms in various antibiotic types and antimicrobial scaffolds and their modes of action, structure-activity relationships, and the contributions of halogen atoms in antimicrobial activity and drug resistance. Other halogenated molecules, including carbohydrates, peptides, lipids, and polymeric complexes, are also reviewed, and the effects of halogenated scaffolds on pharmacokinetics, pharmacodynamics, and factors affecting antimicrobial and antivirulence activities are presented. Furthermore, the potential of halogenation to circumvent antimicrobial resistance and rejuvenate impotent antibiotics is addressed. This review provides an overview of the significance of halogenation, the abilities of halogens to interact in biomolecular settings and enhance pharmacological properties, and their potential therapeutic usages in preventing a postantibiotic era. SIGNIFICANCE STATEMENT: Antimicrobial resistance and the increasing impotence of antibiotics are critical threats to global health. The roles and importance of halogen atoms in antimicrobial drug scaffolds have been established, but comparatively little is known of their pharmacological impacts on drug resistance and antivirulence activities. This review is the first to extensively evaluate the roles of halogen atoms in various antibiotic classes and pharmacological scaffolds and to provide an overview of their ability to overcome antimicrobial resistance.

Resveratrol and Its Analogue 4,4′-Dihydroxy-trans-stilbene Inhibit Lewis Lung Carcinoma Growth In Vivo through Apoptosis, Autophagy and Modulation of the Tumour Microenvironment in a Murine Model. Biomedicines 2022; 10:biomedicines10081784. [PMID: 35892684 PMCID: PMC9332680 DOI: 10.3390/biomedicines10081784] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 07/21/2022] [Accepted: 07/22/2022] [Indexed: 12/24/2022] Open
Abstract
Lung cancer is the most prevalent cancer worldwide. Despite advances in surgery and immune-chemotherapy, the therapeutic outcome remains poor. In recent years, the anticancer properties of natural compounds, along with their low toxic side effects, have attracted the interest of researchers. Resveratrol (RSV) and many of its derivatives received particular attention for their beneficial bioactivity. Here we studied the activity of RSV and of its analogue 4,4′-dihydroxystilbene (DHS) in C57BL/6J mice bearing cancers resulting from Lung Lewis Carcinoma (LLC) cell implantation, considering tumour mass weight, angiogenesis, cell proliferation and death, autophagy, as well as characterization of their immune microenvironment, including infiltrating cancer-associated fibroblasts (CAFs). C57BL/6J mice started treatment with RSV or DHS, solubilised in drinking water, one week before LLC implantation, and continued for 21 days, at the end of which they were sacrificed, and the tumour masses collected. Histology was performed according to standard procedures; angiogenesis, cell proliferation and death, autophagy, infiltrating-immune cells, macrophages and fibroblasts were assessed by immunodetection assays. Both stilbenic compounds were able to contrast the tumour growth by increasing apoptosis and autophagy in LLC tumour masses. Additionally, they contrasted the tumour-permissive microenvironment by limiting the infiltration of tumour-associated immune-cells and, more importantly, by counteracting CAF maturation. Therefore, both stilbenes could be employed to synergise with conventional oncotherapies to limit the contribution of stromal cells in tumour growth.

Abstract
PURPOSE Although doxorubicin chemotherapeutic drug is commonly used to treat various solid and hematological tumors, its clinical use is restricted because of its adverse effects on the normal cells/tissues, especially cardiotoxicity. The use of resveratrol may mitigate the doxorubicin-induced cardiotoxic effects. For this aim, we systematically reviewed the potential chemoprotective effects of resveratrol against the doxorubicin-induced cardiotoxicity. METHODS In the current study, a systematic search was performed based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline for the identification of all relevant studies on "the role of resveratrol on doxorubicin-induced cardiotoxicity" in the electronic databases of Web of Science, PubMed, and Scopus up to March 2021 using search terms in their titles and abstracts. Two hundred and eighteen articles were screened in accordance with a predefined set of inclusion and exclusion criteria. Finally, 33 eligible articles were included in this systematic review. RESULTS The in vitro and in vivo findings demonstrated a decreased cell survival, increased mortality, decreased heart weight, and increased ascites in the doxorubicin-treated groups compared to the control groups. The combined treatment of resveratrol and doxorubicin showed an opposite pattern than the doxorubicin-treated groups alone. Furthermore, this chemotherapeutic agent induced the biochemical and histopathological changes on the cardiac cells/tissue; however, the results (for most of the cases) revealed that these alterations induced by doxorubicin were reversed near to normal levels (control groups) by resveratrol coadministration. CONCLUSION The results of this systematic review stated that coadministration of resveratrol alleviates the doxorubicin-induced cardiotoxicity. Resveratrol exerts these chemoprotective effects through several main mechanisms of antioxidant, antiapoptosis, and anti-inflammatory.

Abstract
Glioblastoma, WHO grade IV astrocytoma, is the most aggressive type of brain tumors. These cancerous cells have a rapid growth rate, tendency to penetrate vital brain structures, molecular heterogeneity, etc. and this cancer is associated with a poor prognosis and low survival rate. Due to the resistance of glioblastoma cells to conventional therapeutic modalities (such as radiation therapy and chemotherapy) as well as the adverse effects of these modalities, the researchers have attempted to discover an appropriate alternative or adjuvant treatment for glioblastoma. Resveratrol, as an herbal and natural polyphenolic compound, has anti-tumoral property and has shown to be effective in GBM treatment. Resveratrol exerts its anti-tumoral effect through various mechanisms such as regulation of cell cycle progression and cell proliferation, autophagy, oxidant system, apoptosis pathways, and so on. Resveratrol in combination with radiation therapy and chemotherapy has also been used. In the present study, we summarized the current findings on therapeutic potentials of resveratrol in glioblastoma radiotherapy and chemotherapy.

Abstract
To expand the applications and enhance the stability and bioactivity of resveratrol (RE), and to simultaneously include the potential health benefits of short chain fatty acids (SCFA) esters of RE were prepared by Steglich reactions with acetic, propionic, and butyric acids, respectively. RE and the esterified RE-SCFA products (including RAE, RPE, and RBE) were analyzed using nuclear magnetic resonance (NMR), Fourier-transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), differential thermal analysis (DTA), and liquid chromatography–mass spectrometry (LC–MS). The FTIR and 13C NMR spectra of the esterified products included ester-characteristic peaks at 1751 cm−1 and 171 ppm, respectively. Moreover, the peaks in the range of 1700 to 1600 cm−1 in the FTIR spectra of the esterified products indicated that the esterification of RE-SCFA was successful. The TGA results revealed that the RE-SCFA esters decomposed at lower temperatures than RE. The peaks in the LC–MS profiles of the esterified products indicated the formation of mono- and diesters, and the calculated monoester synthesis rates ranged between 45.81 and 49.64%. The RE esters inhibited the Cu2+-induced low-density lipoprotein oxidation reaction, exhibited antioxidant activity in bulk oil, and effectively inhibited the hydroxyl radical-induced DNA scission. Moreover, the RE-SCFA esters had better hydrogen peroxide scavenging activity than RE. Our results are the first in the literature to successfully including short chain fatty acids in the esters of resveratrol, and the products could be used as a functional food ingredient in processed foods or can be used as dietary supplements to promote health.

Abstract
Bellevalia saviczii is a medicinal plant used as anti-rheumatic and anti-inflammatory herbal remedy in Iraqi-Kurdistan. The aim of this study was to evaluate the anti-inflammatory activity of its extract and the isolated homoisoflavonoid (Dracol) by studying the Ca2+-dependent NF-kB pathway. Nuclear translocation of p65 NF-kB subunit, as parameter of NF-kB activation, was visualized in human leukemic monocytes by immunofluorescence and Western blot analyses, after cell treatment with B. saviczii root extract or Dracol followed by Lipopolysaccharide stimulation. In parallel, Ca2+ signals responsible for NF-kB activation and levels of inflammatory cytokines were investigated. LPS-induced p65 translocation was evident in monocytes and both treatments, in particular that with Dracol, were able to counteract this activation. Intracellular Ca2+ oscillations were halted and the cytokine release reduced. These results confirm the traditional anti-inflammatory efficacy of B. saviczii and identify one of the molecules in the extract which appears to be responsible of this action.

Abstract
Resveratrol, a natural phytoalexin, exhibits a remarkable range of biological activities, such as anticancer, cardioprotective, neuroprotective and antioxidant properties. However, the therapeutic application of resveratrol was encumbered for its low bioavailability. Therefore, many researchers focused on designing and synthesizing the derivatives of resveratrol to enhance the bioavailability and the pharmacological activity of resveratrol. During the past decades, a large number of natural and synthetic resveratrol derivatives were extensively studied, and the methoxylated, hydroxylated and halogenated derivatives of resveratrol received particular more attention for their beneficial bioactivity. So, in this review, we will summarize the chemical structure and the therapeutic versatility of resveratrol derivatives, and thus provide the related structure activity relationship reference for their practical applications.

Abstract
Background: Inhibition of nitric oxide synthase (NOS) is a well-known experimental model of hypertension (HT). It was shown that oxidative stress contributes to the pathogenesis of HT. Resveratrol is a potent anti-oxidant that is found in red grapes, peanuts and red wine. It improves the NO response and increases endothelial NOS expression, which causes endothelium-dependent vasorelaxation as well as renal vasodilation. We aimed to explore the effects of resveratrol on blood pressure, the water–salt balance and sodium excretion as a reflection of renal function in NOS-inhibited rat models. Methods: Thirty-five male Sprague-Dawley rats (200–250g) were used in this study. In order to obtain hypertension models, an NOS inhibitor, N-nitro-L-arginin (L-NNA) was used. The rats were randomly divided into five groups: controls (given water and 0.8% salty diet) and four groups [given L-NNA, resveratrol (RSV) eluent, RSV, and L-NNA + RSV]. Blood pressures were measured indirectly by the tailcuff method on the first, seventh and 10th days. At the end of the study protocol (10th day), fluid balance, glomerular filtration rate, fractional sodium excretion, and blood and urinesodium and creatinine levels were measured. Results: At the end of the study protocol, blood pressures were higher in only the L-NNA group (117.8 ± 3.5 vs 149.5 ± 2.1 mmHg; p < 0.05), as expected. Additional applications of RSV with L-NNA could not prevent the increase in blood pressure (122.8 ± 7.3 vs 155.4 ± 4.4 mmHg; p < 0.05). There were no remarkable changes in water–salt balance and renal function with the application of resveratrol. Conclusion: Resveratrol was unable to prevent or reverse blood pressure increase in NOS-inhibited rats.

Abstract
Antitumor and antimetastatic effects of resveratrol on tumor-induced lymphangiogenesis through the regulation of M2 macrophages in tumor-associated macrophages currently remain unknown. Therefore, we herein examined the effects of resveratrol on M2 macrophage activation and differentiation, and those of resveratrol-treated condition medium (CM) in M2 macrophages on vascular endothelial cell growth factor (VEGF)-C-induced migration, invasion, and tube formation by human lymphatic endothelial cells (HLECs). Resveratrol (50 μM or 5-50 μM) inhibited the production of interleukin-10 and monocyte chemoattractant protein-1 in M2 macrophages, whereas it promoted that of transforming growth factor-β1. Resveratrol (25 and 50 μM) inhibited the phosphorylation of signal transducer and activator of transcript 3 without affecting its expression in the differentiation process of M2 macrophages. Furthermore, resveratrol-treated CM of M2 macrophages inhibited VEGF-C-induced HLEC migration, invasion, and lymphangiogenesis. Resveratrol (25 mg/kg, twice daily) inhibited tumor growth and metastasis to the lung and also reduced the area of lymphatic endothelial cells in tumors (in vivo). These results suggest that the antitumor and antimetastatic effects of resveratrol were partly due to antilymphangiogenesis through the regulation of M2 macrophage activation and differentiation.

Abstract
We investigated the preventive effects of resveratrol analogue
4,4′-dihydroxy-trans-stilbene (DHS) on cancer invasion and
metastasis. Two different in vivo approaches of mouse and zebrafish lung
cancer invasion models were employed in our study. The in vitro results
showed that DHS displays potent inhibition on anchorage-dependent or -independent
cell growth of LLC cells, leading to impairment of the cell cycle progression with
reduction of cell numbers arresting at the G1 phase, an evident accumulation of
pre-G1 events correlated with apoptotic behaviour. In addition, DHS induces a marked
inhibition of LLC cell migration and matrigel invasion. In a murine lung cancer
model, tumour volume, cell proliferation, and tumour angiogenesis were significantly
inhibited by DHS. Importantly, liver metastatic lesions were significantly reduced
in DHS-treated mice. Similarly, DHS significantly inhibits lung cancer cell
dissemination, invasion and metastasis in a zebrafish tumour model. These findings
demonstrate that DHS could potentially be developed as a novel therapeutic agent for
treatment of cancer and metastasis.

Abstract
AIM To investigate the effects of 3,4,4'-trihydroxy-trans-stilbene (3,4,4'-THS), an analogue of resveratrol, on human non-small-cell lung cancer (NSCLC) cells in vitro. METHODS Cell viability of NSCLC A549 cells was determined by MTT assay. Cell apoptosis was evaluated using flow cytometry and TUNEL assay. Cell necrosis was evaluated with LDH assay. The expression of apoptosis- or autophagy-associated proteins was measured using Western blotting. The formation of acidic compartments was detected using AO staining, neutral red staining and Lysotracker-Red staining. LC3 punctae were analyzed with fluorescence microscopy. RESULTS Treatment with 3,4,4'-THS (10-80 μmol/L) concentration-dependently inhibited the cell viability. It did not cause cell necrosis, but induced apoptosis accompanied by up-regulation of cleavaged PARP, caspase3/9 and Bax, and by down-regulation of Bcl-2 and surviving. It also increased the formation of acidic compartments, LC3-II accumulation and GFP-LC3 labeled autophagosomes in the cells. It inhibited the mTOR-dependent pathway, but did not impair autophagic flux. 3,4,4'-THS-induced cell death was enhanced by the autophagy inhibitors 3-MA (5 mmol/L) or Wortmannin (2 μmol/L). Moreover, 3,4,4'-THS treatment elevated the ROS levels in the cells, and co-treatment with 3-MA further elevated the ROS levels. 3,4,4'-THS-induced apoptosis and autophagy in the cells was attenuated by NAC (10 mmol/L)Conclusion:3,4,4'-THS induces both apoptosis and autophagy in NSCLC A549 cells in vitro. Autophagy inhibitors promote 3,4,4'-THS-induced apoptosis of A549 cells, thus combination of 3,4,4'-THS and autophagy inhibitor provides a promising strategy for NSCLC treatment.

High Potency of a Novel Resveratrol Derivative, 3,3',4,4'-Tetrahydroxy-trans-stilbene, against Ovarian Cancer Is Associated with an Oxidative Stress-Mediated Imbalance between DNA Damage Accumulation and Repair. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2015; 2015:135691.

Abstract
We explored the effect of a new resveratrol (RVT) derivative, 3,3′,4,4′-tetrahydroxy-trans-stilbene (3,3′,4,4′-THS), on viability, apoptosis, proliferation, and senescence of three representative lines of ovarian cancer cells, that is, A2780, OVCAR-3, and SKOV-3, in vitro. In addition, the mechanistic aspects of 3,3′,4,4′-THS activity, including cell redox homeostasis (the production of reactive oxygen species, activity of enzymatic antioxidants, and magnitude of DNA damage accumulation and repair), and the activity of caspases (3, 8, and 9) and p38 MAPK were examined. The study showed that 3,3′,4,4′-THS affects cancer cell viability much more efficiently than its parent drug. This effect coincided with increased generation of reactive oxygen species, downregulated activity of superoxide dismutase and catalase, and excessive accumulation of 8-hydroxy-2′-deoxyguanosine and its insufficient repair due to decreased expression of DNA glycosylase I. Cytotoxicity elicited by 3,3′,4,4′-THS was related to increased incidence of apoptosis, which was mediated by caspases 3 and 9. Moreover, 3,3′,4,4′-THS inhibited cancer cell proliferation and accelerated senescence, which was accompanied by the activation of p38 MAPK. Collectively, our findings indicate that 3,3′,4,4′-THS may constitute a valuable tool in the fight against ovarian malignancy and that the anticancer capabilities of this stilbene proceed in an oxidative stress-dependent mechanism.

Anal Bioanal Chem 2015; 407:5793-801.

Abstract
trans-4,4'-Dihydroxystilbene (DHS) is a naturally occurring resveratrol analog that displayed promising anti-cancer activities in pre-clinical studies. To further probe its therapeutic potential, a sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for the measurement of DHS in rat plasma using electrospray ionization and multiple reaction monitoring in its negative ion mode. This analytical method demonstrated excellent linearity (R(2) > 0.99), selectivity, sensitivity (with a lower limit of quantification of 2.0 ng/mL), accuracy (both intra- and inter-day analytical recovery within 100 ± 15%) and precision (both intra- and inter-day relative standard deviation within 10%). The pharmacokinetic profiles of DHS were subsequently assessed in Sprague-Dawley rats. Following intravenous injection (4 mg/kg), DHS had a moderate apparent volume of distribution of the central compartment (V(c) = 887 ± 297 mL/kg), clearance (Cl = 44.7 ± 5.1 mL/min/kg) and a relatively short mean transit time (MTT = 24.1 ± 8.8 min). When it was given as an oral suspension (10 mg/kg), DHS was absorbed slowly (t max 180 or 300 min) with very limited plasma exposure and absolute oral bioavailability (F = 2.22 ± 0.72%). On the other hand, when DHS was fully solubilized by hydroxypropyl-β-cyclodextrin, it was absorbed rapidly (t(max) 30 or 45 min) with more than 15-fold increase in maximal plasma concentration (C(max)), plasma exposure (AUC(0→last)) and bioavailability (F = 36.3 ± 4.8%). Statistical comparison provided clear evidence that DHS was better than resveratrol from the perspective of pharmacokinetics. In conclusion, further explorations of DHS as an anti-cancer agent are warranted.

A Module Analysis Approach to Investigate Molecular Mechanism of TCM Formula: A Trial on Shu-feng-jie-du Formula. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:731370.

Abstract
At the molecular level, it is acknowledged that a TCM formula is often a complex system, which challenges researchers to fully understand its underlying pharmacological action. However, module detection technique developed from complex network provides new insight into systematic investigation of the mode of action of a TCM formula from the molecule perspective. We here proposed a computational approach integrating the module detection technique into a 2-class heterogeneous network (2-HN) which models the complex pharmacological system of a TCM formula. This approach takes three steps: construction of a 2-HN, identification of primary pharmacological units, and pathway analysis. We employed this approach to study Shu-feng-jie-du (SHU) formula, which aimed at discovering its molecular mechanism in defending against influenza infection. Actually, four primary pharmacological units were identified from the 2-HN for SHU formula and further analysis revealed numbers of biological pathways modulated by the four pharmacological units. 24 out of 40 enriched pathways that were ranked in top 10 corresponding to each of the four pharmacological units were found to be involved in the process of influenza infection. Therefore, this approach is capable of uncovering the mode of action underlying a TCM formula via module analysis.

Abstract
In the present investigation, we examined the effect of Hyuganatsu (Citrus tamurana) extract (HE) on skin fibroblast (TIG-119) proliferation and migration during in vitro wound healing. HE selectively inhibited proliferation of TIG-119 cells at higher concentration (>1.0 mg/mL); at lower concentrations (0.1, 0.25, 0.5, and 0.75 mg/mL), it exhibited linear and time-dependent cell proliferation. In vitro scratch wound healing studies showed that the HE also accelerated the migration of cells towards the wounded region. Cytometric analysis demonstrated that HE extract did not alter G1/0 and S phases of cell cycle in any concentration studied; however, G2/M phases of cell cycle were significantly (P < 0.05) accelerated at 0.75 mg/mL dose. RT-PCR and Western blotting analysis indicated that HE markedly overexpressed levels of Rac-1, Rho-A, and Cdc-42 mRNA and the respective proteins. Cyclin-dependent kinases (Cdk-1 and -2) gene expression activity was significantly (P < 0.05) increased, but protein content decreased during treatment with HE. The induction of Cdk-1 and -2 by HE was abolished by inhibitors, transcription (DRB), and translation (CHX), implying transcriptional regulation that required de novo protein synthesis.

Abstract
Development of small molecule drug-like inhibitors blocking both nitric oxide synthase and NFκB could offer a synergistic therapeutic approach in the prevention and treatment of inflammation and cancer. During the course of evaluating the biological potential of a commercial compound library, 2-phenylindole (1) displayed inhibitory activity against nitrite production and NFκB with IC(50) values of 38.1 ± 1.8 and 25.4 ± 2.1 μM, respectively. Based on this lead, synthesis and systematic optimization have been undertaken in an effort to find novel and more potent nitric oxide synthase and NFκB inhibitors with antiinflammatory and cancer preventive potential. First, chemical derivatizations of 1 and 2-phenylindole-3-carboxaldehyde (4) were performed to generate a panel of N-alkylated indoles and 3-oxime derivatives 2–7. Second, a series of diversified 2-arylindole derivatives (10) were synthesized from an array of substituted 2-iodoanilines (8) and terminal alkynes (9) by applying a one-pot palladium catalyzed Sonogashira-type alkynylation and base-assisted cycloaddition. Subsequent biological evaluations revealed 3-carboxaldehyde oxime and cyano substituted 2-phenylindoles 5 and 7 exhibited the strongest nitrite inhibitory activities (IC(50) = 4.4 ± 0.5 and 4.8 ± 0.4 μM, respectively); as well as NFκB inhibition (IC(50) = 6.9 ± 0.8 and 8.5 ± 2.0 μM, respectively). In addition, the 6′-MeO-naphthalen-2′-yl indole derivative 10at displayed excellent inhibitory activity against NFκB with an IC(50) value of 0.6 ± 0.2 μM.

Abstract
This research has been an effort to develop synthetic resveratrol analogs in order to improve the depigmenting potential of natural resveratrol. Six resveratrol analogs were synthesized and tested for tyrosinase inhibitory activity in vitro, by qualitative and quantitative steps. The results showed the analog C as being the most powerful tyrosinase inhibitor (IA50=65.67±0.60 μg/mL), followed by the analogs B, E, F, A, and D, respectively. The analog C presented a tyrosinase inhibition potential better than natural resveratrol (P<0.001). The best depigmenting activity was provided by the presence of hydroxyl in the orthoposition on the second phenolic ring.

Abstract
4,4'-dihydroxy-trans-stilbene (DHS) is a synthetic analog of resveratrol, a phytoalexin known for its biological activities. We previously demonstrated that DHS exerts an antiproliferative effect on normal human fibroblasts that is higher than that of the natural parent molecule. No evidence regarding its role in human cancer cell lines has been found thus far. In this study, we investigated the effects of DHS both on chemical-induced transformation of BALB/c 3T3 mouse fibroblasts and on the proliferation and invasion of human breast cancer MCF-7 cells. The results showed that DHS markedly suppresses the two-stage (3-methylcholanthrene plus 12-O-tetradecanoylphorbol-13-acetate) cell transformation. Compared with resveratrol, DHS inhibited both anchorage-dependent and -independent MCF-7 growth more efficiently. In addition, a reduction in the number of cells in S-phase, characterized by a concomitant increase in the levels of p21 and p53 proteins, together with a strong inhibition of pRb protein phosphorylation, was observed in DHS-treated cells. Furthermore, DHS effected a strong reduction in matrix metalloproteinase-2 and -9 activities, concomitantly with a marked inhibition of cell adhesion to the extracellular matrix components as well as inhibition of cell migration and invasion. Importantly, modulation of the adhesion molecule E-cadherin was also found in DHS-treated cells. Taken together, these results demonstrate that the two 4,4'-hydroxyl groups on the stilbenic backbone make DHS a more active molecule than resveratrol in inhibiting neoplastic transformation, cancer cell proliferation and invasion. In conclusion, this study suggests that DHS could be a promising anticancer agent.

Abstract
Stilbenes are a class of compounds that has been reported to inhibit a variety of pathological processes during inflammatory reactions. In this study, cis-ampelopsin E, a stilbene isolated from the seeds of Paeonia suffruticosa, was shown to dose-dependently reduce the nitric oxide (NO) production from lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. The reduction in the nitric oxide release occurred in parallel with the comparable inhibition of inducible nitric oxide synthase (iNOS) enzyme expression, which was achieved by cis-ampelopsin E's suppressive effect on nuclear factor-kappa B (NF-κB) signaling activation. By inhibiting LPS-induced inhibitor kinase (IKKα/β) phosphorylation, cis-ampelopsin E significantly decreased LPS-induced IκBα phosphorylation, prevented IκBα degradation, and subsequently reduced the translocating of transcription factor p65 into the nucleus. As a result, the LPS-induced upregulation of NF-κB transcriptional activity was efficiently inhibited. Moreover, it is revealed that cis-ampelopsin E inhibited LPS-induced cyclooxygenase-2 (Cox-2) expression, cPLA2 activation and prostaglandin E2 (PGE2) production. These results, taken together, suggested that cis-ampelopsin E might exert potential anti-inflammatory effects via blockage of the NF-κB signaling pathway.

Abstract
Resveratrol is the subject of intense research as a natural antioxidant and cancer chemopreventive agent. There has been a great deal of interest and excitement in understanding its action mechanism and developing analogs with antioxidant and cancer chemoprevention activities superior to that of the parent compound in the past decade. This work delineates that elongation of the conjugated links is an important strategy to improve the antioxidant activity of resveratrol analogs, including hydrogen atom- or electron-donating ability in homogeneous solutions and antihemolysis activity in heterogeneous media. More importantly, C3, a triene bearing 4,4'-dihydroxy groups, surfaced as an important lead compound displaying remarkably increased antioxidant, cytotoxic, and apoptosis-inducing activities compared with resveratrol.

Abstract
Resveratrol inhibits endothelin-1, a vascular tension regulator. We synthesized the resveratrol analogue 4,4'-dihydroxy-trans-stilbene with 2 hydroxyl groups in the 4 and 4' position to obtain a molecule more active than resveratrol (3,4',5-trihydroxy-trans-stilbene). The results demonstrate that 4,4'-dihydroxy-trans-stilbene led to a significant decrease in total endothelin-1 secretion and in endothelin-1 messenger RNA (mRNA) levels in human endothelial cells. In addition, resveratrol and its analogue decreased endothelin-converting enzyme-1 mRNA levels and further reduced the activity of the enzyme. 4,4'-dihydroxy-trans-stilbene was more active than resveratrol because the new molecule exerted greater activity at the level of endothelin synthesis and conversion, even at a lower concentration. Although 4,4'-dihydroxy-trans-stilbene and resveratrol inhibited formation of reactive oxygen species and lipid peroxidation, the treatment of cells with different oxidant agents did not modify the endothelin-1 release. This finding suggests that the inhibition of endothelin-1 secretion is independent of the antioxidant properties of the 2 compounds. On the basis of these results, the resveratrol analogue 4,4'-dihydroxy-trans-stilbene could be a promising chemopreventive agent against cardiovascular diseases.

Abstract
The antioxidant properties, DNA damage protective activities, and xanthine oxidase (XOD) inhibitory effect of cajaninstilbene acid (CSA) derived from pigeon pea leaves were studied in the present work. Compared with resveratrol, CSA showed stronger antioxidant properties, DNA damage protective activity, and XOD inhibition activity. The IC(50) values of CSA for superoxide radical scavenging, hydroxyl radical scavenging, nitric oxide scavenging, reducing power, lipid peroxidation, and XOD inhibition were 19.03, 6.36, 39.65, 20.41, 20.58, and 3.62 μM, respectively. CSA possessed good protective activity from oxidative DNA damage. Furthermore, molecular docking indicated that CSA was more potent than resveratrol or allopurinol to interact with the active site of XOD (calculated free binding energy: -229.71 kcal mol(-1)).
