PLANTS (BASEL, SWITZERLAND) 2023; 12:3077. [PMID: 37687324 PMCID: PMC10490416 DOI: 10.3390/plants12173077] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 07/28/2023] [Accepted: 08/21/2023] [Indexed: 09/10/2023]
Abstract
Undoubtedly, the advent of antibiotics in the 19th century had a substantial impact, increasing human life expectancy. However, a multitude of scientific investigations now indicate that we are currently experiencing a phase known as the post-antibiotic era. There is a genuine concern that we might regress to a time before antibiotics and confront widespread outbreaks of severe epidemic diseases, particularly those caused by bacterial infections. These investigations have demonstrated that epidemics thrive under environmental stressors such as climate change, the depletion of natural resources, and detrimental human activities such as wars, conflicts, antibiotic overuse, and pollution. Moreover, bacteria possess a remarkable ability to adapt and mutate. Unfortunately, the current development of antibiotics is insufficient, and the future appears grim unless we abandon our current approach of generating synthetic antibiotics that rapidly lose their effectiveness against multidrug-resistant bacteria. Despite their vital role in modern medicine, medicinal plants have served as the primary source of curative drugs since ancient times. Numerous scientific reports published over the past three decades suggest that medicinal plants could serve as a promising alternative to ineffective antibiotics in combating infectious diseases. Over the past few years, phenolic compounds, alkaloids, saponins, and terpenoids have exhibited noteworthy antibacterial potential, primarily through membrane-disruption mechanisms, protein binding, interference with intermediary metabolism, anti-quorum sensing, and anti-biofilm activity. However, to optimize their utilization as effective antibacterial drugs, further advancements in omics technologies and network pharmacology will be required in order to identify optimal combinations among these compounds or in conjunction with antibiotics.

Abstract
Biofilm is complex and consists of bacterial colonies that reside in an exopolysaccharide matrix that attaches to foreign surfaces in a living organism. Biofilm frequently leads to nosocomial, chronic infections in clinical settings. Since the bacteria in the biofilm have developed antibiotic resistance, using antibiotics alone to treat infections brought on by biofilm is ineffective. This review provides a succinct summary of the theories behind the composition of, formation of, and drug-resistant infections attributed to biofilm and cutting-edge curative approaches to counteract and treat biofilm. The high frequency of medical device-induced infections due to biofilm warrants the application of innovative technologies to manage the complexities presented by biofilm.

Abstract
The presence of Vibrio parahaemolyticus, Vibrio alginolyticus, and Vibrio harveyi in aquatic organisms causes vibriosis, leading to their significant mortality. The efficacy of antibiotic treatment is reduced due to increasing antibiotic resistance. As a result, novel therapeutic agents are increasingly needed to treat outbreak of such diseases in aquatic organisms and humans. This study focuses on utilizing the bioactive compounds of Cymbopogon citratus as they are rich in a variety of secondary metabolites which promotes growth, natural immune response and disease resistance against pathogenic bacteria in various ecosystems. In silico studies were performed to evaluate the binding potential of the bioactive compounds against targeted protein beta - lactamase in Vibrio parahaemolyticus and metallo - beta - lactamase in V. alginolyticus via molecular docking. Cymbopogon citratus nanoparticles (CcNps) were synthesized, characterized and toxicity studies were performed by using Vigna radiata, and Artemia nauplii at different concentrations of Cymbopogon citratus nanoparticles. The results revealed that the synthesized nanoparticles were non-ecotoxic and act as potential growth promoters in plants. The antibacterial activity of synthesized Cymbopogon citratus was evaluated using agar well diffusion method. MIC, MBC, and biofilm assays performed by using different concentrations of synthesized nanoparticles. Thus, it was proved that Cymbopogon citratus nanoparticles showed better antibacterial activity against Vibrio species.

Abstract
The purpose of this review is to summarize the current knowledge acquired on herbal products and their active constituents with antimicrobial activity used alone and in combination with antibiotics against multidrug-resistant bacteria. The most promising herbal products and active constituents used alone against multidrug-resistant bacteria are Piper betle (methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus, extended-spectrum beta-lactamase, Acinetobacter baumannii, Pseudomonas aeruginosa), Glycyrrhiza glabra (methicillin-resistant S. aureus, vancomycin-resistant Enterococcus, P. aeruginosa), and berberine (methicillin-resistant S. aureus, A. baumannii, P. aeruginosa), respectively. The synergistic effect of the combination of herbal products and their active constituents with antibiotics against multidrug-resistant bacteria are also described. These natural antibacterial agents can be promising sources of inhibitors, which can modulate antibiotic activity against multidrug-resistant bacteria, especially as efflux pump inhibitors. Other possible mechanisms of action of herbal therapy against multidrug-resistant bacteria including modification of the bacterial cell wall and/or membrane, inhibition of the cell division protein filamenting temperature sensitive Z-ring, and inhibition of protein synthesis and gene expression, all of which will also be discussed. Our review suggests that combination herbal therapy and antibiotics can be effectively used to expand the spectrum of their antimicrobial action. Therefore, combination therapy against multidrug-resistant bacteria may enable new choices for the treatment of infectious diseases and represents a potential area for future research.

Abstract
Aquaculture production is affected by disease outbreak, which affects the production, profitability, and sustainability of the global aquaculture industry. Antibiotics have been widely used to control various infectious diseases. Indiscriminate usage of antibiotics results in development of antibiotic resistance in pathogens. This current study aims to synthesize myrobalan-mediated green silver nanocolloids (MBNc) by using the extract of three myrobalans and characterized by using various physiochemical techniques. Antibacterial potential of MBNc was screened in vibriosis causing pathogens (V. harveyi, V. alginolyticus, V. Parahaemolyticus), and foodborne pathogen S. haemolyticus, isolated from infected fish. Further, the presence of ESBL genes including CTX-M-15 and Amp C was analyzed in control and MBNc-treated strains. From our studies, it was observed that MBNc was very effective in controlling the growth. MBNc confirmed the anti-biofilm property in all tested marine pathogens and effectively abolish the genes encoding CTX-M-15 in tested pathogens. Thus, MBNc can be formulated to control the growth of marine pathogens and it can be used as an alternative to antibiotics to prevent infection in cage culturing and aquafarming.

Abstract
Andrographis paniculata (Burm.f.) Nees is an essential traditional herbal medicine with various bioactivities in Asian countries. The quality of herbal medicines directly affects its clinical efficacy, so a comprehensive strategy, including color assay, chemical profiles, quantitative analysis, and anti-inflammatory activity assay, is constructed to evaluate the quality of A. paniculata in this paper. Here, 16 batches of commercial A. paniculata were collected, and there were noticeable differences in appearance, chemical compounds, and bioactivity among batches. Principal component analysis (PCA) indicated the color and diterpenoid lactones could be used to classify A. paniculat. And then, correlation analysis found the batches with greener color have higher contents of diterpenoid lactones and more efficient anti-inflammatory activity. Based on the results above, the partial least squares (PLS) regression models were finally established to predict the contents of diterpenoid lactones using the color assay data. All diterpenoid lactones models showed good performance, especially neoandrographolide. Notably, PLS regression models were first used for the nondestructive quantitative analysis of A. paniculata. This comprehensive quality evaluation strategy can theoretically elucidate the relationship between good appearance, high contents of diterpenoid lactones, and superior bioactivity of A. paniculata, which is meaningful for its quality control and evaluation. It also laid a theoretical basis for appearance and bioactivity evaluations of high-quality traditional herbal medicine.

Abstract
Andrographolide is the major compound found in the medicinal plant, Andrographis paniculata (Burm.f.) Nees, which accounts for its medicinal properties. Both the plant extract and compound have been reported to exhibit potential cardiovascular activities. This review summarises related studies describing the biological activities and target mechanisms of A. paniculata and andrographolide in vivo and in vitro. The current evidence unambiguously indicated the protective effects provided by A. paniculata and andrographolide administration against myocardial injury. The intervention ameliorates the symptoms of myocardial injury by interfering with the inductive phase of a) inflammatory response mediated by nuclear factor-kappa B (NF-κB), phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt), mitogen-activated protein kinase (MAPK) and signal transducer and activator of transcription 3 (STAT3) signalling molecules; b) oxidative stress via activation of nuclear factor erythroid 2-related factor (Nrf-2) and reduction of enzymes responsible for generating reactive oxygen and nitrogen species; c) intrinsic and extrinsic mechanisms in apoptosis regulated by upstream insulin-like growth factor-1 receptor (IGF-1R) and peroxisome proliferator-activated receptor-alpha (PPAR-α); d) profibrotic growth factors thus reducing cardiac fibrosis, improving endothelial function and fibrinolytic function. In conclusion, A. paniculata and andrographolide possess therapeutic potential in the management of myocardial injury, which requires further validation in human clinical trials.

Abstract
Nanotechnology involves the synthesis of nanoparticles that have been used in the therapeutic application for treating diseases. In this present study, we have adopted the synthesis of myconanoparticles from the extracellular extract of endophytic fungi Penicillium sclerotiorum (PsNps) and validated its antibacterial potential against antibiotic-resistant uropathogenic E. coli and ATCC (25,922) strain of Escherichia coli. Endophytic fungi were isolated from the healthy leaves of Tamarindus indica. The genomic DNA from endophytic fungi was isolated and the ITS region was amplified by polymerase chain reaction (PCR) using universal fungal primers ITS1 and ITS4 and sequenced for the identification of endophytic fungal isolates. Penicillium sclerotiorum extract was used for the synthesis of silver nanoparticles (PsNps) and was characterized by UV-vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), zeta potential, FE-SEM, and Energy dispersive X-ray analysis (EDAX). Antibacterial activity of PsNps was tested against the antibiotic-resistant uropathogenic E. coli and ATCC (25,922) strain of E. coli. Further experiments were carried out to explore the potential of PsNps in regulating the CTX-M-15 gene. The antimicrobial activity showed that the PsNps inhibited growth, biofilm formation in both the strains of E. coli. The expression of the gene encoding CTX-M-15 was downregulated in a resistant strain of uropathogenic E. coli. Our results suggest that the PsNps could be used as an alternative source for antibiotics. Thus, further studies can be conducted to prove the in vivo potential of PsNps and can be formulated for commercialization.

Abstract
Background and aim Andrographis paniculata (Kalmegh), a valuable ancient medicinal herb is used in the treatment of several diseases in most Asian countries including India. Klebsiella pneumoniae is an opportunistic pathogen causing nosocomial infections in human. We have investigated the antimicrobial susceptibility and the presence of AmpC gene in K. pneumoniae strain isolated from the sputum of the patient. Experimental procedure Antibiotic susceptibility test and phenotypic detection of AmpC/ESBL beta-lactamase were performed by combined disc diffusion test. The CEA of A. paniculata was analyzed for its antibacterial potential against susceptible and resistant strains of K. pneumoniae through the broth microdilution method. Molecular detection of AmpC gene was carried by polymerase chain reaction (PCR). Results Antibiotic susceptibility test displayed that the clinical isolate of K. pneumoniae were resistant towards cephalosporins, quinolone and monobactam but susceptible to carbapenems. Combined disk diffusion demonstrated AmpC+ve/ESBL–ve beta-lactamase. 250 μg/ml of CEA extract confirmed the inhibition of bacterial growth and biofilm formation compared to the antibiotic. CEA treated K. pneumoniae displayed a reduction of AmpC by polymerase chain reaction. Conclusion The present study illustrates that CEA extract of A. paniculata demonstrated potentiality to control K. pneumoniae growth and biofilm formation. CEA was able to suppress the expression of gene encoding AmpC. This study proves to be an economical approach to control the growth of K. pneumoniae which causes serious infections. Andrographis paniculata is a medicinal plant with antimicrobial properties. Crude ethyl extract (CEA) of A. paniculata inhibited the growth and biofilm formation in K. pneumoniae strains. CEA was also able to suppress the expression of AmpC. Application of CEA extract is a novel approach to control the growth of multi-drug resistant K. pneumoniae.

Abstract
In this present study, the endophytic bacteria were isolated from the drought-tolerant ornamental plant Pennisetum setaceum. The biomass of endophytic bacteria was utilized for the biogenic synthesis of silver nanoparticles (AgNPs). The synthesis of AgNPs was confirmed by UV-Visible and FTIR spectroscopy followed by SEM analysis. The antibacterial studies were performed through MIC, MBC, and biofilm assays. Efficacy of AgNPs against the human breast cancer (MCF-7) cells was also tested, and the IC50 was determined by MTT assay. In our study, we have observed that the synthesized AgNPs exhibited a dose-dependent cytotoxicity (1-100 μg/mL) against MCF-7 cells and morphological alterations of the cells were also visualized and the IC50 was observed at 50 μg/mL. The treatment of synthesized AgNPs altered the expression of apoptotic proteins including Bax, Bcl-2, and inflammatory marker COX-2 in MCF-7 cells. To the best of our knowledge, this is the first report that demonstrates the AgNPs from endophytic bacteria isolated from the plant Pennisetum setaceum can induce apoptosis in human breast cancer MCF-7 cells. Our results suggest that AgNPs used in this study can be utilized to control human pathogens and can also be utilized to induce apoptosis in breast cancer cells.
