Microorganisms 2023; 11:1242. [PMID: 37317215 DOI: 10.3390/microorganisms11051242] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Revised: 04/27/2023] [Accepted: 05/05/2023] [Indexed: 06/16/2023] Open
Abstract
Helicobacter pylori causes gastritis, peptic ulcers and gastric cancer and affects more than half of the world's population. Although this infection can have serious consequences, no novel cure or remedy have been discovered, the present therapy still relies on a variety of known antibiotics and anti-secretory agents. In the present study, the potential effect of combinations between methanolic extracts of four Algerian medicinal plants, garlic (Allium sativum), red onion (Allium cepa), cumin (Cuminum cyminum L.) and fenugreek (T. foenum-graecum L.), with different strains of lactic acid bacteria against H. pylori, was investigated. Similarly, the in vivo antibacterial effect of fenugreek extract combined with Bifidobacterium breve on H. pylori colonization potential to confirm the enhanced effect of the mixture was explored. Helicobacter pylori was inhibited by all combined mixtures of extracts and probiotics with varying results. The highest anti-H. pylori activities were found in fenugreek/B. breve, cumin/B. breve, garlic/B. breve and onion/B. breve combinations with inhibition diameters of 29, 26, 23 and 25 mm, respectively. Preliminary studies on the effect of probiotics against H. pylori revealed that the inhibition was due to lactic acid and bacteriocins and it was also related to the presence of phenolic compounds in the studied plants, such as gallic acid, caffeic acid, quercetin and vanillic acid. Fenugreek extract was found to inhibit the growth of H. pylori in a concentration-dependent manner. When H. pylori-infected rats were administered B. breve, the infection rate of H. pylori was significantly reduced, while the combination of B. breve and fenugreek extract effectively inhibited H. pylori. In addition, the B. breve and fenugreek extract mixture significantly reduced gastritis in H. pylori-infected rats. These results suggest that this complex mixture may be an alternative to treating diseases caused by H. pylori infection.

Molecular Docking and Dynamics Simulation Studies Predict Potential Anti-ADAR2 Inhibitors: Implications for the Treatment of Cancer, Neurological, Immunological and Infectious Diseases. Int J Mol Sci 2023; 24:ijms24076795. [PMID: 37047766 PMCID: PMC10095294 DOI: 10.3390/ijms24076795] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 04/01/2023] [Accepted: 04/04/2023] [Indexed: 04/08/2023] Open
Abstract
Altered RNA editing has been linked to several neurodevelopmental disorders, including autism spectrum disorder (ASD) and intellectual disability, in addition to depression, schizophrenia, some cancers, viral infections and autoimmune disorders. The human ADAR2 is a potential therapeutic target for managing these various disorders due to its crucial role in adenosine to inosine editing. This study applied consensus scoring to rank potential ADAR2 inhibitors after performing molecular docking with AutoDock Vina and Glide (Maestro), using a library of 35,161 compounds obtained from traditional Chinese medicine. A total of 47 compounds were predicted to be good binders of the human ADAR2 and had insignificant toxicity concerns. Molecular dynamics (MD) simulations, including the molecular mechanics Poisson–Boltzmann surface area (MM/PBSA) procedure, also emphasized the binding of the shortlisted compounds. The potential compounds had plausible binding free energies ranging from −81.304 to −1068.26 kJ/mol from the MM/PBSA calculations. ZINC000085511995, a naphthoquinone had more negative binding free energy (−1068.26 kJ/mol) than inositol hexakisphosphate (IHP) [−873.873 kJ/mol], an agonist and a strong binder of ADAR2. The potential displacement of IHP by ZINC000085511995 in the IHP binding site of ADAR2 could be explored for possible deactivation of ADAR2. Bayesian-based biological activity prediction corroborates the neuropharmacological, antineoplastic and antiviral activity of the potential lead compounds. All the potential lead compounds, except ZINC000014612330 and ZINC000013462928, were predicted to be inhibitors of various deaminases. The potential lead compounds also had probability of activity (Pa) > 0.442 and probability of inactivity (Pi) < 0.116 values for treating acute neurologic disorders, except for ZINC000085996580 and ZINC000013462928. Pursuing these compounds for their anti-ADAR2 activities holds a promising future, especially against neurological disorders, some cancers and viral infections caused by RNA viruses. Molecular interaction, hydrogen bond and per-residue decomposition analyses predicted Arg400, Arg401, Lys519, Trp687, Glu689, and Lys690 as hot-spot residues in the ADAR2 IHP binding site. Most of the top compounds were observed to have naphthoquinone, indole, furanocoumarin or benzofuran moieties. Serotonin and tryptophan, which are beneficial in digestive regulation, improving sleep cycle and mood, are indole derivatives. These chemical series may have the potential to treat neurological disorders, prion diseases, some cancers, specific viral infections, metabolic disorders and eating disorders through the disruption of ADAR2 pathways. A total of nine potential lead compounds were shortlisted as plausible modulators of ADAR2.

Abstract
The most common cancer-related cause of death worldwide is colorectal cancer. It is initiated with the formation of polyps, which further cause the development of colorectal cancer in multistep phases. Colorectal cancer mortality is high despite recent treatment breakthroughs and a greater understanding of its pathophysiology. Stress is one of the major causes of triggering different cellular signalling cascades inside the body and which might turn toward the development of cancer. Naturally occurring plant compounds or phytochemicals are being studied for medical purposes. Phytochemicals' benefits are being analyzed for inflammatory illnesses, liver failure, metabolic disorders, neurodegenerative disorders, and nephropathies. Cancer treatment with fewer side effects and better outcomes has been achieved by combining phytochemicals with chemotherapy. Resveratrol, curcumin, and epigallocatechin-3-gallate have been studied for their chemotherapeutic and chemopreventive potentiality, but hydrophobicity, solubility, poor bioavailability, and target selectivity limit the clinical uses of these compounds. The therapeutic potential is maximized by utilizing nanocarriers such as liposomes, micelles, nanoemulsions, and nanoparticles to increase phytochemical bioavailability and target specificity. This updated literature review discusses the clinical limitations, increased sensitivity, chemopreventive and chemotherapeutic effects, and the clinical limitations of the phytochemicals.

Abstract
There has been tremendous spread of antimicrobial resistance globally, mainly due to the excessive and unnecessary use of antibiotics, making the situation alarming. This has created a need for the development of alternative strategies to selectively target the bacterial pathogenicity without exerting selection pressure for the development of antimicrobial resistance. Targeting quorum sensing (QS)-mediated virulence and biofilms by nontoxic natural products is gaining importance as new control strategy to combat the virulence and biofilms of pathogenic bacteria. In this study, the crude extract of Plumbago zeylanica was fractioned in different solvents using liquid-liquid partitioning to obtain the most bioactive fraction. The inhibitory effect of the bioactive extract of P. zeylanica on QS at sub-minimum inhibitory concentrations (MICs) was studied against Chromobacterium violaceum 12472, Pseudomonas aeruginosa PAO1, and Serratia marcescens MTCC 97. Biofilm inhibition was studied using microtiter plate assay, scanning electron microscopy, and confocal laser scanning microscopy. Major phytocompounds detected were cinnamaldehyde dimethyl acetal, plumbagin, asarone, 4-chromanol, phthalic acid, palmitic acid, ergost-5-en-3-ol, stigmasterol, and β-sitosterol. The violacein production in C. violaceum 12472 was reduced by >80% in the presence of P. zeylanica hexane fraction (PZHF; 200 μg/ml). The most active PZHF inhibited QS-mediated virulence factors of P. aeruginosa PAO1 such as pyocyanin, pyoverdin, rhamnolipid production, motility, etc., significantly at sub-MICs. Similarly, PZHF showed 59 to 76% inhibition of biofilm formation of above test pathogens. The findings revealed that active fraction of P. zeylanica was effective against the QS-regulated functions and biofilms development of Gram -ve pathogenic bacteria.

Abstract
Helicobacter pylori (H. pylori) causes gastric mucosa inflammation and gastric cancer mostly via several virulence factors. Induction of proinflammatory pathways plays a crucial role in chronic inflammation, gastric carcinoma, and H. pylori pathogenesis. Herbal medicines (HMs) are nontoxic, inexpensive, and mostly anti-inflammatory reminding meticulous emphasis on the elimination of H. pylori and gastric cancer. Several HM has exerted paramount anti-H. pylori traits. In addition, they exert anti-inflammatory effects through several cellular circuits such as inhibition of 5'-adenosine monophosphate-activated protein kinase, nuclear factor-κB, and activator protein-1 pathway activation leading to the inhibition of proinflammatory cytokines (interleukin 1α [IL-1α], IL-1β, IL-6, IL-8, IL-12, interferon γ, and tumor necrosis factor-α) expression. Furthermore, they inhibit nitrous oxide release and COX-2 and iNOS activity. The apoptosis induction in Th1 and Th17-polarized lymphocytes and M2-macrophagic polarization and STAT6 activation has also been exhibited. Thus, their exact consumable amount has not been revealed, and clinical trials are needed to achieve optimal concentration and their pharmacokinetics. In the aspect of bioavailability, solubility, absorption, and metabolism of herbal compounds, nanocarriers such as poly lactideco-glycolide-based loading and related formulations are helpful. Noticeably, combined therapies accompanied by probiotics can also be examined for better clearance of gastric mucosa. In addition, downregulation of inflammatory microRNAs (miRNAs) by HMs and upregulation of those anti-inflammatory miRNAs is proposed to protect the gastric mucosa. Thus there is anticipation that in near future HM-based formulations and proper delivery systems are possibly applicable against gastric cancer or other ailments because of H. pylori.

Anti-mycobacterial activity of some medicinal plants used traditionally by tribes from Madhya Pradesh, India for treating tuberculosis related symptoms. JOURNAL OF ETHNOPHARMACOLOGY 2018; 227:113-120. [PMID: 30172059 DOI: 10.1016/j.jep.2018.08.031] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/25/2017] [Revised: 08/24/2018] [Accepted: 08/24/2018] [Indexed: 05/27/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tuberculosis (TB) is one of the highly infectious disease caused by the bacterium Mycobacterium tuberculosis (Mtb). Several medicinal plants are traditionally used by the tribal healers of some tribal pockets of Madhya Pradesh (M.P.), India in the treatment of various ailments including TB related symptoms. The information of traditional knowledge of plants is empirical lacking systematic scientific investigation. AIM OF THE STUDY To provide a scientific rationale for the traditional uses of some medicinal plants in treating prolonged cough, chest complaints and TB by ethnic groups in four districts of the state of M.P., India. The anti-mycobacterial activity of these plants was also investigated against multidrug-resistant (MDR) strains of Mtb. The active plant extracts were also assessed for general cytotoxicity by human monocytic leukemia cell line, THP-1 macrophages. MATERIALS AND METHODS Semi structured interviews and guided field-walk methods were used to gather information on medicinal plants used by the tribal traditional healers. The study was carried out in the tribal pockets of Anuppur, Mandla, Umariya and Dindori districts of M.P., India. A total of 35 plant species distributed in 22 families were selected based on folklore uses suggested by the tribal traditional healer. The ethanol extracts of plants were evaluated for anti-mycobacterial activity against Mtb H37Rv and six MDR clinical isolates of Mtb. The anti-mycobacterial activity of plants was determined in terms of minimum inhibitory concentration (MIC) using standard resazurin microtitre plate assay (REMA). The plant extracts found to be active against Mtb were further evaluated for general cytotoxicity against human THP-1 macrophages using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium (MTT) assay. The selectivity index (SI) of active plant extracts were also calculated on the basis of MIC and cytotoxicity. RESULTS Out of the 35 plants, 11 plant species showed anti-mycobacterial activity with MIC ranging from 500 to 31.25 µg/mL against Mtb H37Rv. The plant extracts also exhibited anti-mycobacterial activity against six multi-drug resistant (MDR) clinical strains of Mtb isolated from sputum samples of pulmonary TB patients. In vitro cytotoxicity of active plant extracts was also assessed in human THP-1 macrophages. The IC50 (50% inhibitory concentration) values of most of the plant extracts on THP-1 was found to be higher than MIC values against Mtb, indicating that the THP-1 cells are not adversely affected at concentrations that are effective against Mtb. Significant anti-mycobacterial activity was observed for eleven plants viz., Alstonia scholaris (L.) R. Br., Glycyrrhiza glabra L., Holorrhena antidysentrica (Roth) Wall. exA.DC., Mallotus philippensis (Lam.) Müll. Arg., Eulophia nuda Lindl., Cocculus hirsutus (L.) Diels, Pueraria tuberosa (Willd.) DC., Cyperus rotundus L., Curcuma caesia Roxb., Sphaeranthus indicus L. and Plumbago zeylanica L. which lends support to their traditional uses. CONCLUSION The present investigation supports the potential role of plants used by tribal healers as our results have shown that these plants exhibit anti-mycobacterial activity in the acceptable range against Mtb. Our study clearly lends support to the traditional uses of some plants in TB related symptoms as we have found them to exhibit significant in vitro anti-TB activity. To the best of our knowledge, anti-mycobacterial activity in plants against Mtb is being reported for the first time from tribal areas of M.P., India by the current study.

Abstract
Helicobacter pylori is the main pathogen that induces chronic gastritis, peptic ulcers, atrophic gastritis, and other gastric disorders, and it is classified as a group I carcinogen. To eradicate H. pylori infection, triple therapy consisting of two antibiotics and a proton pump inhibitor is the most widely recommended first-line therapeutic strategy. Antimicrobial resistance to antibiotics contained in triple therapy could lead to therapeutic regimen failures. Recent studies showed that many natural products, including fruits, vegetables, spices, and medicinal plants, possess inhibitory effects on H. pylori, indicating their potential to be alternatives to prevent and manage H. pylori infection. This review summarizes the effects of natural products on H. pylori infection and highlights the mechanisms of action.

Abstract
CONTEXT Helicobacter pylori is a small, spiral, Gram-negative bacillus that plays a role in the pathogenesis of a number of diseases ranging from asymptomatic gastritis to gastric cancer. Schedule compliance, antibiotic drug resistance, and side-effects of triple or quadruple therapy have led to research for novel candidates from plants. OBJECTIVE The purpose of this paper is to review the most potent medicinal plants of recently published literature with anti-H. pylori activity. For centuries, herbals have been used by traditional healers around the world to treat various gastrointestinal tract disorders such as dyspepsia, gastritis, and peptic ulcer disease. The mechanism of action by which these botanicals exert their therapeutic properties has not been completely and clearly elucidated. Anti-H. pylori properties may be one of the possible mechanisms by which gastroprotective herbs treat gastrointestinal tract disorders. MATERIALS AND METHODS Electronic databases such as PubMed, Google scholar, EBSCO, and local databases were explored for medicinal plants with anti-H. pylori properties between 1984 and 2013 using key words "medicinal plants" and "Helicobacter pylori" or "anti-Helicobacter pylori". RESULTS A total of 43 medicinal plant species belonging to 27 families including Amaryllidaceae, Anacardiaceae, Apiaceae, Apocynaceae, Asclepiadoideae, Asteraceae, Bignoniaceae, Clusiaceae, Chancapiedra, Combretaceae, Cyperaceae, Euphorbiaceae, Fabaceae, Geraniaceae, Lamiaceae, Lauraceae, Lythraceae, Menispermaceae, Myristicaceae, Myrtaceae, Oleaceae, Papaveraceae, Plumbaginaceae, Poaceae, Ranunculaceae, Rosaceae, and Theaceae were studied as herbs with potent anti-H. pylori effects. CONCLUSION Traditional folk medicinal use of some of these plants to treat gastric infections is substantiated by the antibacterial activity of their extracts against H. pylori.

Abstract
More than 50% of the world population is infected with Helicobacter pylori (H. pylori). The bacterium highly links to peptic ulcer diseases and duodenal ulcer, which was classified as a group I carcinogen in 1994 by the WHO. The pathogenesis of H. pylori is contributed by its virulence factors including urease, flagella, vacuolating cytotoxin A (VacA), cytotoxin-associated gene antigen (Cag A), and others. Of those virulence factors, VacA and CagA play the key roles. Infection with H. pylori vacA-positive strains can lead to vacuolation and apoptosis, whereas infection with cagA-positive strains might result in severe gastric inflammation and gastric cancer. Numerous medicinal plants have been reported for their anti-H. pylori activity, and the relevant active compounds including polyphenols, flavonoids, quinones, coumarins, terpenoids, and alkaloids have been studied. The anti-H. pylori action mechanisms, including inhibition of enzymatic (urease, DNA gyrase, dihydrofolate reductase, N-acetyltransferase, and myeloperoxidase) and adhesive activities, high redox potential, and hydrophilic/hydrophobic natures of compounds, have also been discussed in detail. H. pylori-induced gastric inflammation may progress to superficial gastritis, atrophic gastritis, and finally gastric cancer. Many natural products have anti-H. pylori-induced inflammation activity and the relevant mechanisms include suppression of nuclear factor-κB and mitogen-activated protein kinase pathway activation and inhibition of oxidative stress. Anti-H. pylori induced gastric inflammatory effects of plant products, including quercetin, apigenin, carotenoids-rich algae, tea product, garlic extract, apple peel polyphenol, and finger-root extract, have been documented. In conclusion, many medicinal plant products possess anti-H. pylori activity as well as an anti-H. pylori-induced gastric inflammatory effect. Those plant products have showed great potential as pharmaceutical candidates for H. pylori eradication and H. pylori induced related gastric disease prevention.

Abstract
Despite increased use of early detection methods and more aggressive treatment strategies, the worldwide incidence of colorectal cancer is still on the rise. Consequently, it remains urgent to identify novel agents with enhanced efficacy in prevention and/or therapeutic protocols. Our studies focused on the use of Plumbagin, a natural phytochemical that showed promising results against other tumor types, to determine its effectiveness in blocking the proliferation and survival of colon cancer cells in experimental protocols mimicking the environment in primary tumors (attached culture conditions) and in circulating tumor cells (unattached conditions). Under both experimental settings, exposure of HCT116 cells to Plumbagin concentrations in the low micromolar range resulted in cell cycle arrest at the G1 phase, apoptosis via the mitochondrial cell death pathway, and increased production of reactive oxygen species. The cell cycle effects were more noticeable in attached cells, whereas the induction of cell death was more evident in unattached cells. These effects were consistent with the nature and the magnitude of the alterations induced by Plumbagin on the expression levels of a set of proteins known to play key roles in the regulation of cell cycle dynamics, apoptosis mechanisms and cell proliferation. In light of its previously reported lack of toxicity on normal colon cells and the striking anti-survival effect on colon cancer cells observed in our study, Plumbagin should be considered a promising drug for the treatment of colon cancer.

Abstract
BACKGROUND Helicobacter pylori, an infective agent of more than 50% of the world population is prominent to be the main causative factor in the etiologies of chronic, active or type B gastritis, peptic and duodenal ulcer, gastric carcinoma, and mucosa-associated lymphoid tumors. A high prevalence of this bacterium in dental plaque is always reported. Pharmacological treatment of H. pylori infections includes administration of 3-fold therapeutic regimens which are typically used to suppress H. pylori activity. However, antibiotic resistance frequently develops as a consequence of such treatment. Thus, searching for alternative therapies for H. pylori infections is of special interest. MATERIALS AND METHODS In this study, anti H. pylori activities of a traditional antimicrobial drug so-called Shoya and also essential oils of Thymus vulgaris and Eucalyptus globulus were investigated using antimicrobial analysis and serological screening methods. RESULTS The agar dilution method results revealed the Shoya with the highest inhibitory effect against H. pylori. Also serological screening on tested mice showed a significant effect of this drug in lowering the sera amount of anti H. pylori specific IgA and IgG titers. Both of the essential oils showed different degrees of antibacterial effect against H. pylori. CONCLUSION The obtained results showed the antibacterial effect of Shoya powder and Essential oils from Thymus vulgaris and Eucalyptus globulus and purposes new therapeutical alternatives to control the H. pylori infection. Additional studies and clinical trials are necessary to approve the use of these data in health care and pharmacopeia systems.

Abstract
Infection with Helicobacter pylori is strongly associated with gastric cancer and gastric adenocarcinoma. WHO classified H. pylori as a group 1 carcinogen in 1994. Impatiens balsamina L. has been used as indigenous medicine in Asia for the treatment of rheumatism, fractures and fingernail inflammation. In this study, we isolated anti-H. pylori compounds from this plant and investigated their anti- and bactericidal activity. Compounds of 2-methoxy-1,4-naphthoquinone (MeONQ) and stigmasta-7,22-diene-3β-ol (spinasterol) were isolated from the pods and roots/stems/leaves of I. balsamina L., respectively. The minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) for MeONQ were in the ranges of 0.156–0.625 and 0.313–0.625 μg mL−1, respectively, and in the ranges of 20–80 μg mL−1 both of MICs and MBCs for spinasterol against antibiotic (clarithromycin, metronidazole and levofloxacin) resistant H. pylori. Notably, the activity of MeONQ was equivalent to that of amoxicillin (AMX). The bactericidal H. pylori action of MeONQ was dose-dependent. Furthermore, the activity of MeONQ was not influenced by the environmental pH values (4–8) and demonstrated good thermal (121°C for 15 min) stability. MeONQ abounds in the I. balsamina L. pod at the level of 4.39% (w/w db). In conclusion, MeONQ exhibits strong potential to be developed as a candidate agent for the eradication of H. pylori infection.

Abstract
A bioassay-guided fractionation and chemical examination of chloroform extract of Plumbago capensis roots resulted in isolation and characterization of two new napthaquinone derivatives (4, 8) along with six known compounds (1-3, 5-7). Their structures were determined on the basis of extensive spectroscopic (IR, MS, 1D and 2D NMR) data analysis and by comparison with the literature data. All the compounds were tested for their mosquito larvicidal activity against fourth instar larvae of Aedes aegypti, and compared with that of rotenone. Among the tested compounds, isoshinanolone (3) and plumbagin (1) showed excellent toxicity with LC(50) values of 1.26 and 5.43 microg/mL. New compound (8) displayed moderate toxicity against the tested mosquito species.

Abstract
Eradication regimens for Helicobacter pylori infection have some side effects, compliance problems, relapses, and antibiotic resistance. Therefore, alternative anti-H. pylori or supportive antimicrobial agents with fewer disadvantages are necessary for the treatment of H. pylori. We investigated the pH-(5.0, 6.0, 7.0, 8.0, 9.0, and 10.0) and concentration (0.032, 0.064, 0.128, 0.256, 0.514, and 1.024 mg/mL)-dependent antibacterial activity of crude urushiol extract from the sap of the Korean lacquer tree (Rhus vernicifera Stokes) against 3 strains (NCTC11637, 69, and 219) of H. pylori by the agar dilution method. In addition, the serial (before incubation, 3, 6, and 10 min after incubation) morphological effects of urushiol on H. pylori were examined by electron microscopy. All strains survived only within pH 6.0-9.0. The minimal inhibitory concentrations of the extract against strains ranged from 0.064 mg/mL to 0.256 mg/mL. Urushiol caused mainly separation of the membrane, vacuolization, and lysis of H. pylori. Interestingly, these changes were observed within 10 min following incubation with the 1xminimal inhibitory concentrations of urushiol. The results of this work suggest that urushiol has potential as a rapid therapeutic against H. pylori infection by disrupting the bacterial cell membrane.

Abstract
Abstract
Objectives
The aim was to purify and characterise an antimicrobial component from celery (Apium graveolens) seeds, which have been used for centuries as a herbal medicine with reported antibacterial effects.
Methods
A crude alcoholic extract of celery seeds was fractionated by organic solvent extractions, column chromatography and HPLC. Fractions were assayed for antimicrobial activity against the gastric pathogen Helicobacter pylori and other bacteria. The purified antibacterial component was characterised via MS and NMR. Preliminary investigation of its mechanism of action included morphological studies, incorporation of macromolecular precursors, membrane integrity and two-dimensional protein electrophoresis.
Key findings
The purified component, termed ‘compound with anti-Helicobacter activity’ (CAH), had potent bactericidal effects against H. pylori; the minimum inhibitory concentration and minimum bactericidal concentration were 3.15 μg/ml and 6.25–12.5 μg/ml, respectively. CAH (Mr = 384.23; empirical formula C24H32O4) had specific inhibitory effects on H. pylori and was not active against Campylobacter jejuni or Escherichia coli. MS and NMR data were consistent with a dimeric phthalide structure. The results appeared to rule out mechanisms that operated solely by loss of membrane integrity or inhibition of protein or nucleic acid synthesis.
Conclusions
CAH may be suitable for further investigation as a potent agent for treating H. pylori infections.

Abstract
AIM To investigate the inhibitory effects of plumbagin (5-hydroxy-2 methyl-1,4-naphthoquinone) on the invasion and migration and its correlation with matrix metalloproteinase-2 (MMP-2) and urokinase-plasminogen activator (u-PA) in liver cancer HepG2 cells under non-cytotoxic concentrations. METHODS The cell viability was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The adhesion, migration and invasion were measured by cell-matrix adhesion assay and Boyden chamber assay. The MMP-2 and u-PA activities were estimated by gelatin and casein-plasminogen zymography. The mRNA and protein levels of MMP-2, u-PA, urokinase-plasminogen activator receptor (u-PAR), tissue inhibitor of metalloproteinase-2 (TIMP-2), plasminogen activator inhibitor-1 (PAI-1), nuclear factor kappa B (NF-kappaB), c-Fos and c-Jun were evaluated by semi-quantitative reverse transcription polymerase chain reaction and western blotting. Also, the binding abilities of NF-kappaB and activator protein-1 (AP-1) were analyzed by electrophoretic mobility shift assay (EMSA). RESULTS In this study, plumbagin had exhibited an inhibitory effect on the abilities of adhesion, migration and invasion. The results from zymography showed plumbagin treatment may decrease the activities of MMP-2 and u-PA. Further, the mRNA and protein levels of MMP-2, u-PA and u-PAR were significantly reduced, while TIMP-2 and PAI-1 were elevated by plumbagin treatment. Next, plumbagin significantly decreased the nuclear levels of NF-kappaB, c-Fos and c-Jun. Also, treating HepG2 cells with plumbagin leads to dose-dependent inhibition on the binding abilities of NF-kappaB and AP-1. CONCLUSION We demonstrated the inhibitory effects of plumbagin on the invasion, migration and adhesion of HepG2 cells, while plumbagin treatment may decrease the expressions of MMP-2 and u-PA and enhance the expressions of TIMP-2 and PAI-1.

Abstract
Breast cancer remains the major cause of cancer-related deaths in women world-wide. The heterogeneity of breast cancer has further complicated the progress of target-based therapies. Triple negative breast cancers, lacking estrogen receptor, progesterone receptor and the Her-2/neu (ErbB2), represent a highly aggressive breast cancer subtype, that are difficult to treat. Pleiotropic agents, such as those found in nature, can target receptor-positive as well as receptor-negative cancer cells, suggesting that such agents could have significant impact in breast cancer prevention and/or therapy. Plumbagin (5-hydroxy-2-methyl-1, 4-naphthoquinone) is one such agent which has anti-tumor activity against several cancers. However, its mechanism of action against breast cancer is not clearly understood. We hypothesized that plumbagin may act as an effective agent against breast cancer especially triple negative breast cancer. We tested our hypothesis using ER-positive MCF-7 and ER-negative MDA-MB-231 (triple negative) breast cancer cells, and we found that plumbagin significantly inhibits the growth of breast cancer cells with no effect on normal breast epithelial cells. We also found that plumbagin induces apoptosis with concomitant inactivation of Bcl-2 and the DNA binding activity of NF-kappaB. Bcl-2 over-expression resulted in attenuation of plumbagin-induced effects, suggesting that the inhibition of cell growth and induction of apoptosis by plumbagin is in part due to inactivation of NF-kappaB/Bcl-2 pathway. To our knowledge, this is the first report, showing mechanistic and cancer cell specific apoptosis-inducing effects of plumbagin in breast cancer cells, suggesting the potential role of plumbagin in the prevention and/or treatment of breast cancer.

Abstract
PURPOSE To investigate the mechanism of human prostate cancer cell growth inhibition by plumbagin, a constituent of the widely used medicinal herb Plumbago zeylanica L. MATERIALS AND METHODS Cell viability was determined by trypan blue dye exclusion assay. Apoptosis induction was assessed by analysis of cytoplasmic histone-associated DNA fragmentation. Cell cycle distribution and generation of reactive oxygen species (ROS) were determined by flow cytometry. The effect of plumbagin treatment on cellular redox status was determined by analysis of intracellular glutathione (GSH) levels and expression of genes involved in ROS metabolism. RESULTS Plumbagin treatment decreased viability of human prostate cancer cells (PC-3, LNCaP, and C4-2) irrespective of their androgen responsiveness or p53 status. Plumbagin-mediated decrease in cell viability correlated with apoptosis induction, which was accompanied by ROS generation and depletion of intracellular GSH levels. Pretreatment of cells with the antioxidant N-acetylcysteine inhibited plumbagin-mediated ROS generation and apoptosis. Plumbagin treatment also resulted in altered expression of genes responsible for ROS metabolism, including superoxide dismutase 2 (Mn-SOD). CONCLUSION The present study points towards an important role of ROS in plumbagin-induced apoptosis in human prostate cancer cells.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Helicobacter pylori, a gram negative microaerophilic bacterium is a major etiological agent in duodenal, peptic and gastric ulcers. The growing problem of antibiotic resistance by the organism demands the search for novel compounds from plant based sources. AIM OF STUDY The present study is aimed at evaluating the antimicrobial activity of some selected medicinal plants on clinical isolates of H. pylori circulating in Cameroon in a bid to identify potential sources of cheap starting materials for the synthesis of new drugs. MATERIALS AND METHODS Gastric biopsy samples were obtained from patients presenting with gastroduodenal complications. H. pylori was isolated from the specimens following standard microbiology procedures. The disk diffusion method was used to determine the susceptibility of 15 isolates to ten methanol plant extracts (Ageratum conyzoides, Scleria striatinux, Lycopodium cernua, Acanthus montanus, Eryngium foetidium, Aulutandria kamerunensis, Tapeinachilus ananassae, Euphorbia hirta, Emilia coccinea and Scleria verrucosa). The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) for the most active plant extracts were also determined by the agar dilution method. Results were analyzed statistically by the Fisher's exact test. RESULTS All the plants tested demonstrated antimicrobial activity with zone diameters of inhibition ranging from 0-30mm. Of these, A. conyzoides, S. striatinux and L. cernua showed very potent antibacterial activity on the isolates. The lowest MIC and MBC recorded were 0.032mg/mL and 0.098mg/mL respectively. However, the MIC of the extracts ranged from 0.032-1.0mg/mL for S. striatinux; 0.063-0.5mg/mL for L. cernua and 0.063-1.0mg/mL for A. conyzoides. The MBC of the extracts ranged from 0.098-15.0mg/mL for S. striatinux; 0.098-12.5mg/mL for A. conyzoides, and 0.195-12.5mg/mL for L. cernua. The extracts had a wide spectrum of activity. The three most potent extracts possessed significant (P<0.05) inhibitory activities. CONCLUSION The plant extracts may contain compounds with therapeutic activity.

Abstract
The effect of four major parameters, viz., larval age and weight, inoculation dose, incubation temperature and time of harvesting the larvae, on the production of three isolates of nucleopolyhedrovirus of Helicoverpa armigera (HaNPV), viz., Ooty (OTY), Coimbatore (CMB) and Negamum (NGM) were evaluated. Early 5th instar larvae recorded the maximum yield of virus per larva when inoculated with a dose of 5x10(5) POB larva(-1) and incubated at a temperature of 25 degrees C. Also, highest POB yield was recorded when virosed larvae were harvested as cadavers. However, among the isolates tested in this study, CMB isolate collected from Tamil Nadu, India, showed the highest yield per larva in all of the conditions.

Abstract
Thirteen oleanane saponins (1-13), four of which were new compounds (1-4), were isolated from Pteleopsis suberosa Engl. et Diels stem bark (Combretaceae). Their structures were determined by 1D and 2D NMR spectroscopy and ESI-MS spectrometry. The compounds were identified as 2alpha,3beta,19alpha,23,24-pentahydroxy-11-oxo-olean-12-en-28-oic acid 28-O-beta-D-glucopyranosyl ester (1), 2alpha,3beta,19beta,23,24-pentahydroxy-11-oxo-olean-12-en-28-oic acid 28-O-beta-D-glucopyranosyl ester (2), 2alpha,3beta,19alpha,23-tetrahydroxy-11-oxo-olean-12-en-28-oic acid 28-O-beta-D-glucopyranosyl ester (3), and 2alpha,3beta,6beta,19alpha,24-pentahydroxy-11-oxo-olean-12- en-28-oic acid 28-O-beta-D-glucopyranosyl ester (4). The presence of alpha,beta-unsaturated carbonyl function was not common in the oleanane class and the aglycons of these compounds were not found previously in the literature. Moreover, the isolated compounds were tested against Helicobacter pylori standard and vacA, and cagA clinical virulence genotypes. Results showed that compound 6 has an anti-H. pylori activity against three metronidazole-resistant strains (Ci 1 cagA, Ci 2 vacA, and Ci 3).

Abstract
Anti-methicillin-resistant Staphylococcus aureus (MRSA) activity of ethanolic extracts of four medicinal plants namely Acorus calamus (rhizome) Hemidesmus indicus (stem), Holarrhena antidysenterica (bark), and Plumbago zeylanica (root), were detected with inhibition zone size ranged from 11 to 44 mm and minimum inhibitory concentration (MIC) varied from 0.32 to 3.25 mg/mL. Further, ethyl acetate, acetone and methanol fractions of above plants demonstrated antibacterial activity. The potency of these fractions based on zone of inhibition and MIC value was relatively higher in P. zeylanica (ethylacetate fraction), followed by acetone fractions of H. indicus, A. calamus, and H. antidysenterica. Time kill assay with most promising fractions of these plant extracts, demonstrated concentration-dependent killing of MRSA within 9-12 h of incubation. Interestingly, synergistic interaction among alcoholic extracts and some fractions of above four plants was evident against MRSA. Further, synergistic interaction of these extracts was detected with one or more antibiotics tested (tetracycline, chloramphenicol, ciprofloxacin, cefuroxime and ceftidizime). The findings also validate the traditional uses of above plants against infectious diseases. Phytochemical studies demonstrated flavonoids and phenols as major active constituents. Further investigations are needed to characterize the active principle and its interaction mechanism with antibiotics.

Wang YC, Huang TL. High-performance liquid chromatography for quantification of plumbagin, an anti-Helicobacter pylori compound of Plumbago zeylanica L. J Chromatogr A 2005; 1094:99-104. [PMID: 16257295 DOI: 10.1016/j.chroma.2005.07.092] [Citation(s) in RCA: 27] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2005] [Revised: 07/22/2005] [Accepted: 07/25/2005] [Indexed: 12/26/2022]
Abstract
The plant Plumbago zeylanica L. is a semi-climbing shrub that grows throughout Asia and Africa. In our previous study, P. zeylanica L. exhibited high anti-Helicobacter pylori and good bactericidal activities over a wide pH range (pH 2-7). Plumbagin - the major ingredient derived from the roots of P. zeylanica L. - is a naphthoquinone compound. In this study, we investigated plumbagin's anti-H. pylori activity and developed a reversed-phase high-performance liquid chromatography (HPLC) method for quantification of plumbagin from P. zeylanica L. We also observed that plumbagin has strong anti-H. pylori activity, with 0.02-0.16 mg/ml as minimum inhibitory concentrations and 0.16-1.28 mg/ml as minimum bactericidal concentrations. Reversed-phase HPLC was performed with a gradient mobile phase composed of water and methanol, and peaks were detected at 254 nm. Standard curves were linearized in the range of from 10 to 200 microg/ml (regression coefficient r2 = 0.99995). After spikes of 50, 100, and 150 microg/ml of plumbagin standard solution, recovery rates were between 97.45 and 99.24%. Both intra- and inter-day precisions had coefficient variation of less than 1% at concentrations of 50, 100, and 150 microg/ml. The limits of detection and quantitation were 0.02 and 0.06 microg/ml, respectively. Based on validation results, this analytical method is a precise, accurate and stable method to quantify plumbagin derived from P. zeylanica L.
