Abstract
PURPOSE To investigate and systematically describe the mechanism of action of Prunella vulgaris (P. vulgaris) against digestive system tumors and related toxicity reduction. METHODS This study briefly describes the history of medicinal food and the pharmacological effects of P. vulgaris, focusing on the review of the anti-digestive tumor effects of the active ingredients of P. vulgaris and the mechanism of its toxicity reduction. RESULTS The active ingredients of P. vulgaris may exert anti-tumor effects by inducing the apoptosis of cancer cells, inhibiting angiogenesis, inhibiting the migration and invasion of tumor cells, and inhibiting autophagy. In addition, P. vulgaris active ingredients inhibit the release of inflammatory factors and macrophages and increase the level of indicators of oxidative stress through the modulation of target genes in the pathway to achieve the effect of toxicity reduction. CONCLUSION The active ingredients in the medicine food homology plant P. vulgaris not only treat digestive system tumors through different mechanisms but also reduce the toxic effects. P. vulgaris is worthy of being explored more deeply.

Li Z, He Q, Xu F, Yin X, Guan Z, Song J, He Z, Yang X, Situ C. Exploring the Antibacterial Potential and Underlying Mechanisms of Prunella vulgaris L. on Methicillin-Resistant Staphylococcus aureus. Foods 2024; 13:660. [PMID: 38472772 DOI: 10.3390/foods13050660] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2023] [Revised: 02/08/2024] [Accepted: 02/16/2024] [Indexed: 03/14/2024] Open
Abstract
Prunella vulgaris L. (PV) is a widely distributed plant species, known for its versatile applications in both traditional and contemporary medicine, as well as in functional food development. Despite its broad-spectrum antimicrobial utility, the specific mechanism of antibacterial action remains elusive. To fill this knowledge gap, the present study investigated the antibacterial properties of PV extracts against methicillin-resistant Staphylococcus aureus (MRSA) and assessed their mechanistic impact on bacterial cells and cellular functions. The aqueous extract of PV demonstrated greater anti-MRSA activity compared to the ethanolic and methanolic extracts. UPLC-ESI-MS/MS tentatively identified 28 phytochemical components in the aqueous extract of PV. Exposure to an aqueous extract at ½ MIC and MIC for 5 h resulted in a significant release of intracellular nucleic acid (up to 6-fold) and protein (up to 10-fold) into the extracellular environment. Additionally, this treatment caused a notable decline in the activity of several crucial enzymes, including a 41.51% reduction in alkaline phosphatase (AKP), a 45.71% decrease in adenosine triphosphatase (ATPase), and a 48.99% drop in superoxide dismutase (SOD). Furthermore, there was a decrease of 24.17% at ½ MIC and 27.17% at MIC in tricarboxylic acid (TCA) cycle activity and energy transfer. Collectively, these findings indicate that the anti-MRSA properties of PV may stem from its ability to disrupt membrane and cell wall integrity, interfere with enzymatic activity, and impede bacterial cell metabolism and the transmission of information and energy that is essential for bacterial growth, ultimately resulting in bacterial apoptosis. The diverse range of characteristics exhibited by PV positions it as a promising antimicrobial agent with broad applications for enhancing health and improving food safety and quality.

Abstract
Objective To evaluate antagonistic role of titanium oxide nanoparticles against selected dental caries promoting bacteria. Methods This in vitro-experimental study was conducted at Pakistan Institute of Engineering and Applied Sciences (PIEAS), National Institute of Health (NIH) and School of Dentistry (SOD), Islamabad for the period of one year from February 2022 to January 2023. Modified hydrothermal heating method was used to prepare titanium oxide nanoparticles (TiO2Nps). Size, shape, phase, band gap energy, surface and elemental composition of Nps were deciphered by application of various modern techniques including x-ray diffraction spectroscopy (XRD), scanning electron microscopy (SEM), dynamic light scattering (DLS), UV-Vis diffuse reflectance spectroscopy (DRS), atomic force microscopy (AFM), energy dispersive x-ray spectroscopy (EDX). Antimicrobial action of nanoparticles was evaluated against representatives of gram-positive (mono-derm) and Gram negative bacteria (di-derm) responsible for promoting dental caries. The zones of inhibition were calculated by disc diffusion method for each bacterial strain. Results Characterization revealed that TiO2Nps were having an average size of 54nm, showing anatase-rutile phase having spherical, with very few- irregularly shaped particles. TiO2Nps contained only pure titanium and oxygen in the EDX image but organic compounds in FTIR scan. Results of antimicrobial action indicated their potent bactericidal action against Pseudomonas aeruginosa (20mm), Escherichia coli (19mm) and Lactobacillus acidophilus (19nm) while comparatively less activity against Staphylococcus aureus (16mm).. Conclusion TiO2Nps fabricated by modified protocol displayed an effective antimicrobial activity and can be used as an alternative to the contemporary chemotherapeutics against selected bacterial pathogens to prevent dental caries.

Abstract
The aim of this study was to confirm the anti-inflammatory effect and explore the adverse effects and underlying mechanisms of Prunella vulgaris L., which has been extensively used for hundreds of years in East Asia. Network pharmacology studies predicted that glucocorticoids (GCs), GC-targeting molecules, and brain-derived neurotrophic factor (BDNF) were intensively involved in the anti-inflammation and glucose intolerance. To attest the effects and underlying mechanisms, C57 male mice were randomly divided into 5 groups, control (C), dexamethasone (Dex), water extract of P. vulgaris (PE 35 or 70 mg), and PE (70 mg) + mifepristone (PEM). After a 3-week treatment, acetic acid-induced writhing and hot plate tests confirmed the peripheral and central analgesic effects, respectively. Plasma GCs and BDNF were significantly increased. Coincidently, plasma pro-inflammatory cytokines, including IL1β, IL6, and IL10, were decreased by PE treatment, which were blocked by the application of mifepristone ( P < 0.5). Western blots confirmed GC receptor (GR) translocation, and decreased cyclooxygenase 2 in the lumber spine by PE treatment. Food intake was impeded after a 4-week PE treatment, but the ratio of bodyweight gain to food intake was increased in a time-dependent manner. An intraperitoneal glucose tolerance test disclosed that PE treatment impaired glucose disposal in mice. Quantitative polymerase chain reaction (PCR) showed that hepatic GC-responsive genes such as GC-induced leucine zipper protein and glucose-6-phosphatase catalytic subunit 1 were up-regulated, and hypothalamic neuropeptide Y and agouti-related protein expressions were decreased by PE treatment. Hypothalamic BDNF was up-regulated, whereas hepatic BDNF was down-regulated. The regulation of these genes by PE was reversed by mifepristone administration. In conclusion, PE treatment plays analgesic and glucose regulation roles simultaneously through GC-induced signaling pathways, and P. vulgaris may provide a natural ligand of GR for the treatment of inflammation with glucose dysregulation.

Abstract
As a traditional Chinese herbal formula, Xiasangju (XSJ) is widely used in China for antipyresis and influenza treatment. However, XSJ still fails to have a comprehensive summary of the research progress in the last decade. This review summarizes the advanced research on the extraction process, phytochemistry, pharmacological activity, and quality control of XSJ. Current research mainly focuses on quality control and the pharmacological effects of single herbs and active ingredients, but many pharmacological mechanisms of the formula are unclear. The development of active ingredients reflects the active characteristics of triterpenes, phenolic acids and flavonoids, but the hepatotoxicity of Prunella vulgaris L. has not been taken into account. XSJ has extensive historical practical experiences, while systematic clinical trials remain lacking. Therefore, it is necessary to study the active ingredients and define the mechanisms of XSJ to develop multiple applications, and further studies on the dose range between its hepatoprotective activity and hepatotoxicity are necessary to improve the safety of the clinical application. In this review, the current problems are discussed to facilitate the reference basis for the subsequent research on the development of XSJ and future application directions.

Abstract
Abstract
Background: Prunella vulgaris L., known as self-healing herb, is a widely spread species in the spontaneous flora with beneficial effects on human health, a fact proven in particular by Asian researchers. The aim of this study was to evaluate the antitumor activity and the antibacterial effect on different bacterial strains, including multidrug-resistant ones, depending on the type of solvent used (aqueous, hydroalcoholic), the plant product taken into consideration (spike inflorescence, leaf), its quantity and the concentration of active principles.
Material and method: For screening of antimicrobial susceptibility, both minimum inhibitory concentration and minimum bactericidal concentration were determined on Escherichia coli, Klebsiella pneumoniae, Providencia stuartii, Pseudomonas aeruginosai, and methicillin-resistant Staphylococcus aureus species, including reference strains and hospital strains. Leaves and flower extracts (aqueous and 70% methanolic) were first assessed, and the one with the best antibacterial potential was further tested as a concentrated extract. The antitumor activity was determined on MDA-MB-231 breast adenocarcinoma cells and on a non-tumor cell line, MCF-10A breast epithelial cells by means of Alamar blue technique and Scratch assay.
Results: Inflorescence extracts showed better bacteriostatic effects than leaf extracts on most bacteria, in both aqueous and hydroalcoholic extracts. The concentrated extract of spike inflorescence showed measurable activity with good effects on Gram-positive bacteria, but also on multidrug-resistant Gram-negative ones. The 70% methanolic extract of the species Prunella vulgaris L. (spike inflorescence) demonstrated a concentration-dependent cytotoxic and anti-migratory activity on MDA-MB-231 breast cancer cells, while affecting the non-tumor cell line less.
Conclusions: The results suggest that Prunella vulgaris extracts present antibacterial potential in the complementary treatment of multidrug-resistant infections. The extract from the spike inflorescence of Prunella vulgaris L. produced a dose and time-dependent reduction in cell viability and migration, eliciting a stronger effect on the breast adenocarcinoma cell line.

Abstract
Background and Objective: With the emergence of antibiotic resistance and the hospital acquired infection, the interest for antimicrobial agents has recently increased again in public health. Copper is recommended as a supplementary method of increasing biological safety in the hospital environment. The objective of this study was to determine the antibacterial activity of copper sulfate salts on strains of bacterial pathogens isolated from different clinical pictures in different health establishment in Algeria. Methods: A total of 25 different bacterial isolates (16 Enterobacteriaceae, 5 Staphylococci, and 4 Pseudomonas) were tested for susceptibility to copper sulfate using minimum inhibitory concentration (MIC-Cu) and minimum bactericidal concentrations (MBC-Cu) determinations. All isolates were also tested for susceptibility to six antibiotics. Results: Antibiotic susceptibility studies revealed that 100% of isolates were resistant to one or more antibiotics. Fifty two percent of isolates were very susceptible to copper sulfate, with MICs ranging from 100 to 200 µg/ml. MBC-Cu = 1600 μg/ml showed the best bactericidal effect against the great majority of studied bacteria (52%). A good bactericidal activities of copper sulfate were recorded against Proteus vulgaris and Staphylococcus aureus (MBC/MIC=1). The Gram-negative bacteria isolates which were copper resistant also showed a high resistance to chloramphenicol (r=0.78) and Trimethoprime (r=0.61). Furthermore, the strains that were no-susceptible to three different antimicrobial classes (Escherichia coli, Staphylococcus saprophyticus) were not resistant to copper sulfate. Conclusion: Copper sulfate salts has significant antibacterial activity against multi-drug resistant nosocomial pathogens.

Therapeutic potential of medicinal plants for the management of urinary tract infection: A systematic review. Clin Exp Pharmacol Physiol 2019; 46:613-624. [PMID: 30932202 DOI: 10.1111/1440-1681.13092] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2018] [Revised: 03/25/2019] [Accepted: 03/26/2019] [Indexed: 01/21/2023]
Abstract
Urinary tract infection (UTI) is one of the most severe public health problem affecting both sexes but females are more susceptible due to the differences in urogenital and reproductive anatomy, physiology and lifestyle. As in UTI, different parts of the urinary tract are affected and morbidity due to UTI is more common in women of all ages and older men. Due to multi-drug resistant strains and high recurrence rate, UTI has become a major socioeconomic burden. The current review article was aimed to describe the natural therapeutic strategies to manage and cure the UTI. For this purpose, different databases including Google Scholar, Cochrane database, and PubMed etc. were explored. Inclusion criteria were any research article investigating the current therapy of UTI. It was found that microbial infections including Escherichia coli, Enterococcus faecalis and Klebsiella species are the major causes of UTI with different signs and symptoms including painful urination or dysuria, hematuria, urinary urgency, burning micturition, frequent urination, nausea, and vomiting. Antibiotics like trimethoprim, sulfamethoxazole, quinolone etc. as the first choice of the drug are used worldwide. However, due to microbial resistance, several life-threatening side effects, repeated high doses, high cost and low efficacy of these antibiotics motivated the researchers to explore natural remedies for the treatment of UTI. Herbal medicines are effective to combat bacterial resistance with high efficacy, and easy availability with minimal or no side effects. For these reasons it has attained the attention of researchers wanting to explore the herbal treatment of UTI. Vaccinium macrocarpon, Tribulus terrestris, Trachyspermum copticum, Cinnamomum verum and Hybanthusenn easpermus are some common medicinal plants reported to have therapeutic potential for the management and cure of the UTI. Although herbal medicines have more potential over conventional medicine but more discoveries are required to explore the phytoconstituents and their mechanism of action responsible for the management and cure of UTI.
