Abstract
OBJECTIVE Asthma is an airway inflammatory disease caused by activation of numerous immune cells including macrophages. Bakuchicin (BKC) is known to exhibit anti-inflammatory effects and type 2 T helper (Th2) regulation, but has not been investigated for airway inflammation. This study aimed to evaluate the effects of BKC on airway inflammation and demonstrate the mechanisms of macrophage polarization. METHODS The anti-inflammatory effects were determined using lipopolysaccharide (LPS)-stimulated macrophages. The ovalbumin (OVA)-induced asthma mouse model was used to evaluate the effects of BKC on airway inflammation and Th2 responses. Moreover, the effect of BKC on macrophage polarization was confirmed in bone marrow-derived macrophages (BMDMs) differentiation. RESULTS BKC suppressed nitric oxide production and expression of pro-inflammatory cytokines by inhibiting signaling pathway in LPS-stimulated macrophages. In an OVA-induced asthma model, BKC treatment alleviated histological changes and mast cell infiltration and reduced the levels of eosinophil peroxidase, β-hexosaminidase, and immunoglobulin levels. In addition, BKC alleviated Th2 responses and M2 macrophage populations in bronchoalveolar fluid. In BMDMs, BKC suppressed IL-4-induced M2 macrophage polarization and the expression of M2 markers such as arginase-1 and Fizz-1 through inhibiting sirtuin 2 levels. CONCLUSION BKC could be a drug candidate for the treatment of allergic asthma.

The accessible chromatin landscape of lipopolysaccharide-induced systemic inflammatory response identifying epigenome signatures and transcription regulatory networks in chickens. Int J Biol Macromol 2024; 266:131136.

Abstract
Lipopolysaccharide (LPS) can induce systemic inflammatory response (SIR) in animals. Understanding the regulatory mechanism of SIR and therapies to ensure healthy growth is urgently needed. Chromatin remodeling plays a crucial role in the expression of genes involved in immune diseases. In the present study, the ATAC-seq analysis revealed 3491 differential open chromatin sites in the spleen of chicks with SIR induced by LPS challenge, and we presented the motifs on these sites and the associated transcription factors. The regulatory network was presented by combining the differential open chromatin data with the mRNAs and exploded cytokines. Interestingly, the LPS challenge could regulate the mRNA expression of 202 genes through chromatin reprogramming, including critical genes such as TLE1 and JUN, which regulate signaling pathways such as I-κB kinase/NF-κB, Toll-like receptor, and downstream cytokine genes. Furthermore, dietary daidzein could inhibit DNA topoisomerase II, which reprograms the spatial conformation of chromatin in the inflammatory response and attenuates SIR. In conclusion, we successfully identified key genes directly regulated by chromatin reprogramming in SIR and demonstrated the chromatin epigenome signatures and transcriptional regulatory network, which provides an important reference for further research on avian epigenetics. There is great potential for alleviating SIR using dietary daidzein.

Abstract
Isoflavones were synthesized via Suzuki-Miyaura coupling of 3-iodochromones and para-methoxybenzene- and para-phenolboronic acid. In our hands, conditions commonly used for similar cross couplings turned out to be unsuccessful or difficult to reproduce, for example, due to the unplanned partial cleavage of MOM-protecting groups. Using Pd(dba)2 as a precatalyst and tricyclohexylphosphine as an activating ligand, reliable cross-coupling conditions were identified. In all cases, notably higher yields of isoflavones were obtained with para-phenolboronic acid than with para-methoxybenzene boronic acid. This observation and the commercial availability of para-phenolboronic acid suggest that for the synthesis of the important 3'-prenyl- or 3',5'-diprenylisoflavone substitution pattern a synthetic route that introduces the prenyl substituents after the Pd-catalyzed cross-coupling step, thereby avoiding laborious and protecting-group-intensive multistep syntheses of C-prenylated arene boronic acids, is advantageous.

Abstract
Psoralea corylifolia L. (PCL), referred to as "Bu-gu-zhi" in Chinese, has great medicinal values since ancient times. PCL is the dried ripe fruit of Psoralea corylifolia L., which has been widely used in traditional Chinese medicine (TCM) for the treatment of kidney-yang deficiency, enuresis and urinary frequency, chills and pain of the waist and knees, dawn diarrhea and vitiligo. In this paper, a systematic of the botany, traditional uses, phytochemistry, pharmacology, toxicology, quality control and pharmacokinetics of PCL was presented, along with future research directions. According to the results, PCL contains approximately 163 chemical components, including coumarins, flavonoids, monoterpene phenols, benzofurans, glycosides, lipids, fatty acids, and volatile oils. PCL and its active ingredients have a variety of pharmacological activities, such as anti-inflammatory, antibacterial, antiviral, antioxidant, antitumor, antiosteoporosis, cardioprotective, neuroprotective, and immunomodulatory. Further study of quality control standards and potential mechanisms of PCL is also needed. In addition, more toxicological studies will also contribute to the progress of clinical trials.

Abstract
The novel SARS-CoV-2 (severe acute respiratory syndrome coronavirus) has emerged as a significant threat to public health with startling drawbacks in all sectors globally. This study investigates the practicality of some medicinal plants for SARS-CoV-2 therapy using a systematic review and meta-analysis of their reported SARS-CoV-1 inhibitory potencies. Relevant data were systematically gathered from three databases, viz., Web of Science, PubMed and Scopus. The information obtained included botanical information, extraction method and extracts concentrations, as well as the proposed mechanisms. Fourteen articles describing 30 different plants met our eligibility criteria. Random effects model and subgroup analysis were applied to investigate heterogeneity. According to subgroup analysis, the substantial heterogeneity of the estimated mean based on the IC 50 values reporting the most potent anti-SARS-CoV 3C--like protease (3CLpro) inhibitors (10.07 %, p < 0.0001), was significantly higher compared to the most active anti-SARS-CoV papain-like protease (PLpro) inhibitors (6.12 %, p < 0.0001). More importantly, the literature analysis revealed that fruit extracts of Rheum palmatum L. and the compound cryptotanshinone isolated from the root of Salvia miltiorrhiza (IC 50 = 0.8 ± 0.2 μmol L-1) were excellent candidates for anti--SARS-CoV targeting PLpro. Meanwhile, iguesterin (IC 50 = 2.6 ± 0.6 μmol L-1) isolated from the bark of Tripterygium regelii emerged as the most excellent candidate for anti-SARS--CoV targeting 3CLpro. The present systematic review and meta-analysis provide valuable and comprehensive information about potential medicinal plants for SARS-CoV-2 inhibition. The chemotypes identified herein can be adopted as a starting point for developing new drugs to contain the novel virus.

Abstract
Systemic lupus erythematosus (SLE) is a complex, chronic autoimmune disease, whose etiology includes both genetic and environmental factors. Individual genetic risk factors likely only account for about one-third of observed heritability among individuals with a family history of SLE. A large portion of the remaining risk may be attributable to environmental exposures and gene-environment interactions. This review focuses on SLE risk associated with environmental factors, ranging from chemical and physical environmental exposures to lifestyle behaviors, with the weight of evidence supporting positive associations between SLE and occupational exposure to crystalline silica, current smoking, and exogenous estrogens (e.g., oral contraceptives and postmenopausal hormones). Other risk factors may include lifestyle behaviors (e.g., dietary intake and sleep) and other exposures (e.g., ultraviolet [UV] radiation, air pollution, solvents, pesticides, vaccines and medications, and infections). Alcohol use may be associated with decreased SLE risk. We also describe the more limited body of knowledge on gene-environment interactions and SLE risk, including IL-10, ESR1, IL-33, ITGAM, and NAT2 and observed interactions with smoking, UV exposure, and alcohol. Understanding genetic and environmental risk factors for SLE, and how they may interact, can help to elucidate SLE pathogenesis and its clinical heterogeneity. Ultimately, this knowledge may facilitate the development of preventive interventions that address modifiable risk factors in susceptible individuals and vulnerable populations.

Abstract
BACKGROUND Dried fruits of Psoralea corylifolia L. (Psoraleae Fructus) is one of the most popular traditional Chinese medicine with treatment for nephritis, spermatorrhea, pollakiuria, asthma, and various inflammatory diseases. Bakuchiol is main meroterpenoid with bioactive diversity from Psoraleae Fructus. This study was designed to seek structural diverse bakuchiol derivants with anti-inflammatory activities from this plant. METHODS Various column chromatography methods were used for isolation experiment. Structures and configurations of these compounds were determined by spectroscopic methods and single-crystal X-ray diffraction. Their inhibition on nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages were evaluated by the Griess reaction. RESULTS Twelve unpresented bakuchiol dimmers, bisbakuchiols M-U (1-9) and bisbakuchiol ethers A-C (10-12), along with five known compounds (13-17), were isolated from the fruits of Psoralea corylifolia L. Compounds 1-3, 10-12, 16 and 17 exhibited inhibitory activities against LPS-induced NO production in RAW264.7 macrophages, and the inhibition of compound 1 (half maximal inhibitory concentration (IC50) value = 11.47 ± 1.57 μM) was equal to that of L-N(6)-(1-iminoethyl)-lysine (IC50 = 10.29 ± 1.10 μM) as a positive control. CONCLUSIONS Some compounds exhibited inhibitory activities against NO production, and the study of structure-activity relationship suggested that uncyclized compounds with oxygen substitution at C-12/12' showed strong inhibitory activities, and carbonyl units contributed to enhanced activities.

Abstract
Despite many advances in therapy, glioblastoma (GB) is still characterized by its poor prognosis. The main reason for this is unsuccessful treatment, which slightly extends the duration of remission; thus, new regimens are needed. One of many types of chemotherapeutics that are being investigated in this field is topoisomerase inhibitors, mainly in combination therapy with other drugs. On the other hand, the search for new anti-cancer substances continues. Neobavaisoflavone (NBIF) is a natural compound isolated from Psoralea corylifolia L., which possesses anti-oxidant, anti-inflammatory, and anti-cancer properties. The aim of this study was to evaluate the effect of NBIF in human U-87 MG glioblastoma cells in comparison to normal human NHA astrocytes, and to examine if it influences the activity of irinotecan, etoposide, and doxorubicin in this in vitro model. We demonstrated that NBIF decreases U-87 MG cells viability in a dose-dependent manner. Furthermore, we found that it inhibits cell growth and causes glutathione (GSH) depletion more intensely in U-87 MG cells than in astrocytes. This study also provides, for the first time, evidence of the potentialization of the doxorubicin effect by NBIF, which was shown by the reduction in the viability in U-87 MG cells.

Shoji M, Esumi T, Tanaka N, Takeuchi M, Yamaji S, Watanabe M, Takahashi E, Kido H, Yamamoto M, Kuzuhara T. Organic synthesis and anti-influenza A virus activity of cyclobakuchiols A, B, C, and D. PLoS One 2021; 16:e0248960. [PMID: 33770117 PMCID: PMC7997032 DOI: 10.1371/journal.pone.0248960] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2020] [Accepted: 03/09/2021] [Indexed: 12/01/2022] Open
Abstract
Novel antiviral agents for influenza, which poses a substantial threat to humans, are required. Cyclobakuchiols A and B have been isolated from Psoralea glandulosa, and cyclobakuchiol C has been isolated from P. corylifolia. The structural differences between cyclobakuchiol A and C arise due to the oxidation state of isopropyl group, and these compounds can be derived from (+)-(S)-bakuchiol, a phenolic isoprenoid compound present in P. corylifolia seeds. We previously reported that bakuchiol induces enantiospecific anti-influenza A virus activity involving nuclear factor erythroid 2-related factor 2 (Nrf2) activation. However, it remains unclear whether cyclobakuchiols A–C induce anti-influenza A virus activity. In this study, cyclobakuchiols A, B, and C along with cyclobakuchiol D, a new artificial compound derived from cyclobakuchiol B, were synthesized and examined for their anti-influenza A virus activities using Madin-Darby canine kidney cells. As a result, cyclobakuchiols A–D were found to inhibit influenza A viral infection, growth, and the reduction of expression of viral mRNAs and proteins in influenza A virus-infected cells. Additionally, these compounds markedly reduced the mRNA expression of the host cell influenza A virus-induced immune response genes, interferon-β and myxovirus-resistant protein 1. In addition, cyclobakuchiols A–D upregulated the mRNA levels of NAD(P)H quinone oxidoreductase 1, an Nrf2-induced gene, in influenza A virus-infected cells. Notably, cyclobakuchiols A, B, and C, but not D, induced the Nrf2 activation pathway. These findings demonstrate that cyclobakuchiols have anti-influenza viral activity involving host cell oxidative stress response. In addition, our results suggest that the suitably spatial configuration between oxidized isopropyl group and phenol moiety in the structure of cyclobakuchiols is required for their effect.

Abstract
Recently, integrated and sustainable methods for extracting active substances from plant materials using green solvents, i.e., ionic liquids, have gained increasing attention. Ionic liquids showsuperiority over conventional organic solvents; however, they also exhibit negative factors and problems, such as high viscosity, poor water intermiscibility, intensive foaming and poor affinity for fat-soluble substances. The proposed method utilizes ultrasonic-enhanced surface-active ionic liquid-based extraction and defoaming (UESILED) to improve the extraction efficiency of ionic liquids. Single-factor experiments and a Box-Behnken design (BBD) were utilized to optimize the extraction procedure. The optimal conditions were as follows: extraction solvent, [C10MIM]Br; ultrasonic treatment time, 28 min; ultrasonic irradiation power, 437 W; liquid-solid ratio, 10 mL/g; particle size, 60 ~ 80 mesh; ultrasonication temperature, 313 K; and [C10MIM]Br solution concentration, 0.5 mol/L. In comparison with those of other reference extraction methods, the proposed method exhibited higher yields of two furocoumarins and operational feasibility. Moreover, the mechanism of UESILED was elaborated in terms of accelerating infiltration, dissolution and defoaming. The feasible and efficient ultrasonic-enhanced ionic liquid-based extraction established in this study strongly contributes to overcoming the limitations of ionic liquid solvents. The present research indicates that this improved process will be beneficial for the extraction of other fat-soluble substances and provides promising concepts and experimental data.

Abstract
The article presents the characteristics of bakuchiol - a natural compound valuable in cosmetology and pharmacology. The only source for obtaining this specific meroterpenic phenol is the fruit of the species Cullen corylifolium (Psoralea corylifolia). Bakuchiol has recently been playing a significant role in cosmetology as a "natural substitute" for retinol, free of side effects.Clinical studies confirm valuable cosmetological properties of bakuchiol, such as anti-ageing, anti-pigmentation and anti-acne effects. Scientific research has also shown valuable pharmacological properties of bakuchiol, such as anti-cancer, hepatoprotective, cardioprotective, hypoglycemic, hypolipemic, and antidepressant. In addition, antioxidant, anti-inflammatory and antimicrobal activities of bakuchiol, valuable from the point of view of both cosmetology and therapy, have also been confirmed.A separate part of the article is devoted to the botanical, chemical and pharmacological characteristics of the species C. corylifolium as the main source for obtaining bakuchiol.

Abstract
Cancer is caused by a variety of pathways, involving numerous types of enzymes. Among them three enzymes i.e. Cyclin-dependent kinase-2 (CDK-2), Human topoisomerase IIα, and Vascular Endothelial Growth Factor Receptor-2 (VEGFR-2) are three of the most common enzymes that are involved in the cancer development. Although many chemical drugs are already available in the market for cancer treatment, plant sources are known to contain a wide variety of agents that are proved to possess potential anticancer activity. In this experiment, total thirty phytochemicals were analyzed against the mentioned three enzymes using different tools of bioinformatics and in silico biology like molecular docking study, drug likeness property experiment, ADME/T test, PASS prediction, and P450 site of metabolism prediction as well as DFT calculation to determine the three best ligands among them that have the capability to inhibit the mentioned enzymes. From the experiment, Epigallocatechin gallate was found to be the best ligand to inhibit CDK-2, Daidzein showed the best inhibitory activities towards the Human topoisomerase IIα, and Quercetin was predicted to be the best agent against VEGFR-2. They were also predicted to be quite safe and effective agents to treat cancer. However, more in vivo and in vitro analyses are required to finally confirm their safety and efficacy in this regard.

Abstract
Seventeen undescribed heterodimers of meroterpene phenol, psocorylins A-Q, were isolated from the fruits of Psoralea corylifolia. Their another monomeric unit derived from flavonone, chalcone, coumarin and isoflavone, respectively. Psocorylins A-E were rare natural spiroketals with the skeleton of 1,4,8-trioxaspiro[4.5]decane deriving from flavonone, and their plausible biosynthetic pathways were proposed. These structures were established by spectroscopic methods. Their absolute configurations were assigned via single-crystal X-ray diffraction, electronic circular dichroism (ECD) calculations and Rh2(OCOCF3)4-induced ECD spectra. Psocorylins B-E, F, M and Q exhibited potent cytotoxic activities against different kinds of tumor cells with IC50 values less than 10 μM.

Abstract
OBJECTIVE Systemic lupus erythematosus (SLE) affects black women more frequently than other racial/gender groups. In past studies, largely consisting of white and Asian cohorts, cigarette smoking was associated with increased SLE risk, and moderate alcohol consumption was associated with decreased SLE risk. The aim of this study was to assess associations of smoking and alcohol consumption with the risk of incident SLE among black women, using data from a long-term, prospective, follow-up study. METHODS The Black Women's Health Study enrolled 59,000 black women in 1995 and collected data on demographics, health status, and medical and lifestyle variables. Follow-up questionnaires that were given every 2 years identified incident disease and updated risk factors. Cases of incident SLE that met the American College of Rheumatology revised criteria for SLE as updated in 1997 were confirmed through medical record review. Cox regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (95% CI) for associations of cigarette smoking and alcohol intake with incidence of SLE. RESULTS A total of 127 incident SLE cases from 1995 to 2015 (mean age 43 years at diagnosis) were confirmed. Compared to never smokers, the risk of SLE among ever smokers was elevated, but not significantly (HR 1.45 [95% CI 0.97-2.18]). Risk was similar for current and past smoking and increased nonsignificantly with increasing pack-years. The HR was 0.71 (95% CI 0.45-1.12) for current drinking relative to never drinking, with a HR of 0.43 (95% CI 0.19-0.96) for ≥4 drinks/week. CONCLUSION Findings from this large study of SLE risk among black women are consistent with previous results from studies in other populations of increased risk of SLE associated with cigarette smoking and decreased risk with moderate alcohol consumption.

Abstract
Polyphenols in foods and dietary supplements are commonly used for the prevention and treatment of a variety of malignancies, including breast cancer. However, daily intake by patients with breast cancer is controversial, as these compounds may stimulate cancer growth. Estrogens serve key roles in breast cancer cell proliferation; therefore, understanding the interaction between endogenous steroid hormones and natural dietary polyphenols is essential. Currently, comprehensive knowledge regarding these effects remains limited. The current review summarizes the dose-dependent in vitro and in vivo interactions of resveratrol and other dietary polyphenols with estrogen precursors, active estrogens, catechol estrogens and their respective glucuronidated, sulfated, glutathionated or O-methylated metabolites in estrogen receptor alpha negative (ERα-) and positive (ERα+) breast cancer. Which estrogen-metabolizing enzymes are affected by polyphenols is also reviewed in detail. Furthermore, the impacts of dose and therapy duration on disease development and progression in patients with breast cancer are discussed. The present article is part of a Special Issue titled 'CSR 2018'.

Abstract
The objective of this study was to investigate the effect of trans-resveratrol, a potent antioxidant with anti-inflammatory and chemopreventive properties, naturally occurring in many fruits and plants on lymphocytes proliferation and also on macrophages metabolic and phagocytic activity. The aim of this study was to demonstrate the immunomodulatory effects of the compound on fish immunocompetent cells and determine the type of this interaction (immunosuppression or immunostimulation). Proliferative activity of lymphocytes was studied by MTT assay, and the respiratory burst was evaluated using the respiratory burst activity (RBA) test. Phagocytic killing was tested using the PKA test. The experiment have shown that trans-resveratrol suppressed blood B cells, while there was no significant influence on blood T lymphocytes. However, insignificant stimulatory effect occurred at the lowest concentration. In addition, the compound inhibited proliferation of T and B lymphocytes isolated from the organs. Importantly, trans-resveratrol caused stimulation of blood and organs macrophages phagocytic killing, and also increased the respiratory burst of macrophages isolated from organ. These results suggest a potential use of trans-resveratrol as an immunomodulator of innate immunity in fish. This is particularly important, as this kind of resistance plays leading role in protecting the body against infection. In comparison, adaptive immunity is slower and also much less precise.

Abstract
The formation of paired helical filaments (PHF), which are composed of hyperphosphorylated Tau protein dissociating from microtubules, is one of the pathological hallmarks of Alzheimer's disease (AD) and other tauopathies. The most important phosphatase that is capable of dephosphorylating Tau at AD specific phospho-sites is protein phosphatase 2 A (PP2A). Here we show that resveratrol, a polyphenol, significantly induces PP2A activity and reduces Tau phosphorylation at PP2A-dependent epitopes. The increase in PP2A activity is caused by decreased expression of the MID1 ubiquitin ligase that mediates ubiquitin-specific modification and degradation of the catalytic subunit of PP2A when bound to microtubules. Interestingly, we further show that MID1 expression is elevated in AD tissue. Our data suggest a key role of MID1 in the pathology of AD and related tauopathies. Together with previous studies showing that resveratrol reduces β-amyloid toxicity they also give evidence of a promising role for resveratrol in the prophylaxis and therapy of AD.

Lv L, Liu B. Anti‑tumor effects of bakuchiol on human gastric carcinoma cell lines are mediated through PI3K/AKT and MAPK signaling pathways. Mol Med Rep 2017; 16:8977-8982. [PMID: 28990045 DOI: 10.3892/mmr.2017.7696] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2015] [Accepted: 02/02/2017] [Indexed: 11/06/2022] Open
Abstract
Bakuchiol is extracted from Psoralea corylifolia, a member of the Leguminosae family, has been used in Indian Ayurvedic and Chinese traditional medicine, and it possesses an anticancer effect. The primary aim of the present study was to identify the molecular mechanisms underlying the anticancer effect of bakuchiol monoterpenes. Bakuchiol treatment significantly inhibited NUGC3 human gastric cancer cell viability in a concentration dependent manner. In addition, bakuchiol significantly increased the apoptotic cell population in the sub‑G1 phase, and Annexin‑V‑fluorescein isothiocyanate/propidium iodide double staining confirmed the increase in apoptosis. Nuclear fragmentation and the formation of apoptotic organelles were promoted in bakuchiol‑treated NUGC3 cells. Western blotting results indicated that bakuchiol treatment significantly decreased procaspase‑3,6,8,9 and poly (ADP‑ribose) polymerase (PARP) expression levels, increased cleaved caspase‑3 and cleaved PARP expression levels, and increased the B cell lymphoma‑2 associated X, apoptosis regulator:B cell lymphoma‑extra large ratio. Bakuchiol‑treated NUGC3 cells demonstrated significantly reduced phosphorylated (p‑) protein kinase B (AKT) protein expression levels and elevated p‑extracellular signal related kinase 1/2 (ERK1/2), p‑c‑Jun N‑terminal kinase (JNK) and p‑p38. Bakuchiol‑induced cell death was mitochondrial dependent, through modulation of phosphoinositide 3‑kinase/AKT and mitogen‑activated protein kinase signaling pathways. These findings demonstrated that bakuchiol possesses potential for treating human gastric cancer.

Abstract
The present study was aimed to investigate the effect of resveratrol on the viability of HT-144 melanoma cells and formation of melanin. MTT assay was used for analysis of cell viability and western blot for determination of phospho-Mek 1/2, phospho-Erk 1/2 (Tyr-204), Mitf, PBG-D and p-CREB-1 expression. MTT assay results showed that treatment of HT-144 cells with various doses of resveratrol led to a concentration dependent inhibition of proliferation. The antiproliferative activity was significant at 15 μM concentration of resveratrol after 24 h. Western blot analysis revealed that resveratrol caused significant reduction in the expression of phospho-extracellular signal related kinase (p-ERK) and p-MEK 1/2. Additionally, tyrosinase activity was increased by 1.5-6.8-fold on increasing the concentration of resveratrol from 1 to 15 μM. Resveratrol treatment also enhanced the expression of cAMP-response element-binding proteins (CREB) after 24 h. Furthermore resveratrol treatment up-regulated porphobilinogen deaminase (PBG-D) expression in HT-144 cells. Taken together, the study demonstrates that resveratrol treatment inhibits proliferation and promotes melanogenesis of HT-144 cells through inhibition of MEK/ERK pathway. Therefore, resveratrol has a scope for further evaluation against melanogenesis.

Abstract
PURPOSE OF REVIEW This review examines evidence relating environmental factors to the development of systemic lupus erythematosus (SLE). RECENT FINDINGS The strongest epidemiologic evidence exists for the associations of silica, cigarette smoking, oral contraceptives, postmenopausal hormone therapy and endometriosis, with SLE incidence. Recent studies have also provided robust evidence of the association between alcohol consumption and decreased SLE risk. There are preliminary, conflicting or unsubstantiated data that other factors, including air pollution, ultraviolet light, infections, vaccinations, solvents, pesticides and heavy metals such as mercury, are related to SLE risk. Biologic mechanisms linking environmental exposures and SLE risk include increased oxidative stress, systemic inflammation and inflammatory cytokine upregulation, and hormonal triggers, as well as epigenetic modifications resulting from exposure that could lead to SLE. SUMMARY Identifying the environmental risk factors related to risk of SLE is essential as it will lead to increased understanding of pathogenesis of this complex disease and will also make risk factor modification possible for those at increased risk.

Influence of Alcohol Consumption on the Risk of Systemic Lupus Erythematosus Among Women in the Nurses' Health Study Cohorts. Arthritis Care Res (Hoboken) 2017; 69:384-392. [PMID: 27273851 DOI: 10.1002/acr.22945] [Citation(s) in RCA: 46] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2015] [Revised: 04/08/2016] [Accepted: 05/24/2016] [Indexed: 12/16/2022]
Abstract
OBJECTIVE Moderate alcohol consumption has antiinflammatory properties and is associated with reduced cardiovascular disease and rheumatoid arthritis risks. We investigated the association between alcohol consumption and systemic lupus erythematosus (SLE) risk among women followed in the Nurses' Health Study (NHS) cohorts. METHODS We conducted a prospective cohort analysis among 204,055 women in NHS (1980-2012) and NHSII (1989-2011) who were free of connective tissue disease and provided alcohol information at baseline. Alcohol consumption was assessed using a semiquantitative food frequency questionnaire every 2-4 years. We validated incident SLE through medical record review after self-report. Cox proportional hazards models estimated hazard ratios (HRs) for SLE based on cumulative average alcohol intake, adjusting for potential confounders. Results were meta-analyzed using DerSimonian and Laird random-effects models. We further investigated SLE risk associated with wine, beer, and liquor intake. RESULTS We identified 125 incident SLE cases in NHS and 119 in NHSII. Mean ± SD age at SLE diagnosis was 55.8 ± 9.5 years in NHS and 43.4 ± 7.7 years in NHSII. Compared to no alcohol intake, the meta-analyzed multivariable HR for cumulative alcohol consumption ≥5 gm/day was 0.61 (95% confidence interval [95% CI] 0.41-0.89). When limiting alcohol exposure to >4 years prior to SLE diagnosis, the multivariable HR was similar: 0.61 (95% CI 0.41-0.91). Women who drank ≥2 servings/week of wine had significantly decreased SLE risk (HR 0.65, 95% CI 0.45-0.96) compared to women who did not drink wine. CONCLUSION In these large prospective cohorts, we demonstrated an inverse association between moderate alcohol consumption (≥5 grams or 0.5 drink/day) and SLE risk in women.

Abstract
Bakuchicin is a furanocoumarin isolated from the seeds of Psoralea corylifolia, which is used in oriental medicine. However, limited information on the pharmacokinetics of bakuchicin is available and in addition, no determined method has been devised to quantify bakuchicin levels in the plasma. In the present study, we developed and validated a quantification method using liquid chromatography (LC) coupled with tandem mass spectrometry (LC-MS/MS), which was applied to a pharmacokinetic investigation in mouse plasma. LC was performed using an ACE 5 C18 column, and a mixture of acetonitrile and water containing 0.1% formic acid was used as the mobile phase at a flow rate of 220μL/min. Bakuchicin transition ions in multiple reaction-monitoring modes using positive ionization were observed at m/z 187.0 to m/z 131.0. Bakuchicin and the internal standard (reserpine) had retention times of 4.5 and 4.3min, respectively. Acceptable linearity (r2=0.996) was observed over the concentration range of 20-1000ng/mL, with a lower quantification limit of 20ng/mL in mouse plasma. This method was successfully applied to determine the pharmacokinetic parameters of bakuchicin in mouse plasma and showed that the bioavailability of bakuchicin was 58.3% at 5mg/kg oral administration.

Abstract
Chondrosarcoma is a malignant primary bone tumor. Sirtuin-1 (SIRT1), which is a member of sirtuin family, plays a dual role either in cancer promotion or suppression. There is no report about the role of SIRT1 in the human chondrosarcoma cells. Resveratrol is a potent activator of SIRT1. However, its effects on chondrosarcoma have not been extensively studied. Here, we investigated the role of SIRT1 induction by resveratrol in human chondrosarcoma cell growth and tumor progression. Resveratrol significantly decreased cell viability and induced cell apoptosis in human chondrosarcoma cells in a dose-dependent manner. The protein expression and activity of SIRT1 were activated after treatment with resveratrol. Resveratrol significantly inhibited NF-κB signaling by deacetylating the p65 subunit of NF-κB complex, which could be reversed by siRNA-SIRT1 transfection or deacetylation inhibitor MS-275. Resveratrol induced-apoptosis involved a caspase-3-mediated mechanism. Both siRNA-SIRT1 transfection and MS-275 significantly inhibited the resveratrol-induced caspase-3 cleavage and activity in human chondrosarcoma cells. Moreover, in vivo chondrosarcoma xenograft study revealed a dramatic reduction in tumor volume and the increased SIRT1 and cleaved caspase-3 expressions in tumors by resveratrol treatment. These results suggest that resveratrol induces chondrosarcoma cell apoptosis via a SIRT1-activated NF-κB deacetylation and exhibits anti-chondrosarcoma activity in vivo.

Abstract
Systemic lupus erythematosus (SLE) is a multisystem disease with a complex etiology. Its risk is higher among women, racial and ethnic minorities, and individuals with a family history of SLE or related autoimmune diseases. It is believed that genetic factors interact with environmental exposures throughout the lifespan to influence susceptibility to developing SLE. The strongest epidemiologic evidence exists for increased risk of SLE associated with exposure to crystalline silica, current cigarette smoking, use of oral contraceptives, and postmenopausal hormone replacement therapy, while there is an inverse association with alcohol use. Emerging research results suggest possible associations of SLE risk with exposure to solvents, residential and agricultural pesticides, heavy metals, and air pollution. Ultraviolet light, certain infections, and vaccinations have also been hypothesized to be related to SLE risk. Mechanisms linking environmental exposures and SLE include epigenetic modifications resulting from exposures, increased oxidative stress, systemic inflammation and inflammatory cytokine upregulation, and hormonal effects. Research needs to include new studies of environmental risk factors for SLE in general, with a focus on lifetime exposure assessment. In addition, studies in susceptible subgroups, such as family members, studies based on genetic risk profiles, and studies in individuals with evidence of pre-clinical autoimmunity based on the detection of specific auto-antibodies are also required. Understanding the role of environmental exposures in the development of SLE may help identify modifiable risk factors and potential etiological mechanisms.

Abstract
Increasing bacterial resistance to common drugs is a major public health concern for the treatment of infectious diseases. Certain naturally occurring compounds of plant sources have long been reported to possess potential antimicrobial activity. This study was aimed to investigate the antibacterial activity and possible mechanism of action of andrographolide (Andro), a diterpenoid lactone from a traditional medicinal herb Andrographis paniculata. Extent of antibacterial action was assessed by minimal bactericidal concentration method. Radiolabeled N-acetyl glucosamine, leucine, thymidine, and uridine were used to determine the effect of Andro on the biosyntheses of cell wall, protein, DNA, and RNA, respectively. In addition, anti-biofilm potential of this compound was also tested. Andro showed potential antibacterial activity against most of the tested Gram-positive bacteria. Among those, Staphylococcus aureus was found to be most sensitive with a minimal inhibitory concentration value of 100 μg/mL. It was found to be bacteriostatic. Specific inhibition of intracellular DNA biosynthesis was observed in a dose-dependent manner in S. aureus. Andro mediated inhibition of biofilm formation by S. aureus was also found. Considering its antimicrobial potency, Andro might be accounted as a promising lead for new antibacterial drug development.

Abstract
BACKGROUND Chonemorpha fragrans (Moon) Alston, a liana belonging to family Apocynaceae, is used in traditional medicinal systems for the treatment of various ailments. It is an unexplored medicinal plant with respect to its anticancer potential. OBJECTIVE Cytotoxicity of sequential as well as crude extracts of in vivo plant parts (leaves, bark, and roots), in vitro cultures, and callus were compared. MATERIALS AND METHODS 3-(4,5- dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) cell proliferation assay was used to compare the extracts of various in vivo plant parts (leaves, bark, and roots) along with in vitro culture systems (in vitro plantlets, callus). Furthermore, the extracts were used to evaluate inhibition of key enzymes involved in replication, i.e. topoisomerase (Topo) I and II, DNA polymerase, to check the probable mechanism of action for this cytotoxicity. RESULTS MTT assay showed that the chloroform extract of callus has potent anticancer potential. The plant has a promising anticancer activity against human colon epithelium, lung carcinoma, and epidermoidal carcinoma cell lines. It was found to possess Topo as well as DNA polymerase inhibitory activity. CONCLUSION The results have pointed toward pharmaceutical importance of this plant. This study is the first report of exploring the antiproliferative potential as well as inhibition studies of key enzymes involved in replication, which was useful to point out probable mechanism of action for extracts of C. fragrans. SUMMARY It's a first report of cytotoxicity studies and inhibition of enzyme involved in the replication process by Chonemorpha fragrans plant extracts. The results reveal the pharmaceutical importance of this plant. From various assays performed here, a potent anticancer potential of chloroform extract of callus was revealed showing Topo I (E. coli and human) inhibitory activity, DNA pol inhibitory activity. Considering the importance of these activities, plant further needs to be explored in detail for in vivo cancer studies as well as for its metabolite content.

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
Bakuchicin is a furanocoumarin isolated from Psoralea corylifolia and shows several biological activities. Although there have been studies on the biological effects of bakuchicin, its modulation potency of CYP activities has not been previously investigated. Here, we investigated the inhibitory effects of bakuchicin on the activities of CYP isoforms by using a cocktail of probe substrates in pooled human liver microsomes (HLMs) and human recombinant cDNA-expressed CYP. Bakuchicin strongly inhibited CYP1A-mediated phenacetin O-deethylation with an IC50 value of 0.43 μM in HLMs. It was confirmed by human recombinant cDNA-expressed CYP1A1 and CYP1A2 with a Ki value of 0.11 μM and 0.32 μM, respectively. A Lineweaver-Burk plot indicated that the inhibition mechanism of bakuchicin was competitive inhibition. Overall, this is the first study to investigate the potential CYP1A1 and CYP1A2 inhibition associated with bakuchicin and to report its competitive inhibitory effects on HLMs.

Abstract
Nucleotides containing adenosine play pivotal roles in every living cell. Adenosine triphosphate (ATP), for example, is the universal energy currency, and ATP-consuming processes also contribute to posttranslational protein modifications. Nevertheless, detecting the turnover of adenosine nucleotides in the complex setting of a cell remains challenging. Here, we demonstrate the use of fluorogenic analogs of ATP and adenosine tetraphosphate to study nucleotide hydrolysis in lysates of human cell lines and in intact human cells. We found that the adenosine triphosphate analog is completely stable in lysates of human cell lines, whereas the adenosine tetraphosphate analog is rapidly turned over. The observed activity in human cell lysates can be assigned to a single enzyme, namely, the human diadenosine tetraphosphate hydrolase NudT2. Since NudT2 has been shown to be a prognostic factor for breast cancer, the adenosine tetraphosphate analog might contribute to a better understanding of its involvement in cancerogenesis and allow the straightforward screening for inhibitors. Studying hydrolysis of the analogs in intact cells, we found that electroporation is a suitable method to deliver nucleotide analogs into the cytoplasm and show that high FRET efficiencies can be detected directly after internalization. Time-dependent experiments reveal that adenosine triphosphate and tetraphosphate analogs are both processed in the cellular environment. This study demonstrates that these nucleotide analogs indeed bear the potential to be powerful tools for the exploration of nucleotide turnover in the context of whole cells.

Abstract
Influenza represents a substantial threat to human health and requires novel therapeutic approaches. Bakuchiol is a phenolic isoprenoid compound present in Babchi (Psoralea corylifolia L.) seeds. We examined the anti-influenza viral activity of synthetic bakuchiol using Madin-Darby canine kidney cells. We found that the naturally occurring form, (+)-(S)-bakuchiol, and its enantiomer, (-)-(R)-bakuchiol, inhibited influenza A viral infection and growth and reduced the expression of viral mRNAs and proteins in these cells. Furthermore, these compounds markedly reduced the mRNA expression of the host cell influenza A virus-induced immune response genes, interferon-β and myxovirus-resistant protein 1. Interestingly, (+)-(S)-bakuchiol had greater efficacy than (-)-(R)-bakuchiol, indicating that chirality influenced anti-influenza virus activity. In vitro studies indicated that bakuchiol did not strongly inhibit the activities of influenza surface proteins or the M2 ion channel, expressed in Chinese hamster ovary cells. Analysis of luciferase reporter assay data unexpectedly indicated that bakuchiol may induce some host cell factor(s) that inhibited firefly and Renilla luciferases. Next generation sequencing and KeyMolnet analysis of influenza A virus-infected and non-infected cells exposed to bakuchiol revealed activation of transcriptional regulation by nuclear factor erythroid 2-related factor (Nrf), and an Nrf2 reporter assay showed that (+)-(S)-bakuchiol activated Nrf2. Additionally, (+)-(S)-bakuchiol up-regulated the mRNA levels of two Nrf2-induced genes, NAD(P)H quinone oxidoreductase 1 and glutathione S-transferase A3. These findings demonstrated that bakuchiol had enantiomer-selective anti-influenza viral activity involving a novel effect on the host cell oxidative stress response.

Isobavachalcone attenuates lipopolysaccharide-induced ICAM-1 expression in brain endothelial cells through blockade of toll-like receptor 4 signaling pathways. Eur J Pharmacol 2015; 754:11-8.

Abstract
Inflammation has been implicated in the pathogenesis of various cerebral diseases. Thus, control of brain inflammation is regarded as one of the important therapeutic strategies for the treatment of neurodegenerative diseases such as Alzheimer׳s disease and stroke. Isobavachalcone, a flavonoid from Psoralea corylifolia, is known to possess a wide spectrum of biological activities and is expected to be useful in preventing or treating neurodegenerative diseases. However, very little is known regarding its effects on cerebral inflammation. In this study, we examined the effect of isobavachalcone on leukocyte adhesion and intercellular adhesion molecule-1 (ICAM-1) expression in brain endothelial cells activated with lipopolysaccharide (LPS) and explored the possible mechanisms involved. Isobavachalcone significantly down-regulated LPS-induced ICAM-1 expression and leukocyte-endothelial cell adhesion and suppressed NF-κB activity which is implicated in the expression of ICAM-1. It attenuated ICAM-1 expression as well as NF-κB transcriptional activity induced by macrophage-activating lipopeptide 2-kDa (MALP-2) or polyriboinosinic polyribocytidylic acid (poly[I:C]). Isobavachalcone also down-regulated LPS or poly[I:C]-induced expression of IFN-β, which can indirectly activate NF-κB. These data imply that isobavachalcone can modulate both MyD88-dependent and TRIF-dependent signaling of toll-like receptor 4 (TLR4). Taken together, our data suggest that isobavachalcone inhibits LPS-induced ICAM-1 expression and leukocyte adhesion to brain endothelial cell by blocking TLR4 signaling and thus, has the potential to ameliorate neuronal injury in brain diseases associated with inflammation.
