Tetradentate Schiff bases are synthesized from o-phenylenediamine, 5-bromo Salicylaldehyde, and 3-Acetyl-6-methyl-pyran-2, 4-dione, and then its colored complexes of Sm (III) and Eu (III) are formed. The structure of ligand and complexes are characterized by elemental analysis, magnetic susceptibility, thermal analysis, X-ray diffraction, 1H-NMR, mass, IR, UV-visible spectra, and conductometry. TGA/DSC spectral and kinetic parameter of the complexes was studied eagerly. The x-ray diffraction data proposes Tetragonal crystal system for Sm (III) complexes and orthorhombic for Eu (III) complexes. The ligand and their metal complexes were subjected for antibacterial activity against Escherichia coli, Staphylococcus aureus, Pseudomonas Aeruginosa using the agar cup-plate method, and antifungal activity was observed by poison plate method against Aspergillus niger, Aspergillus flavus, Penicillium chrysogenum. The results obtained above are in good agreement with previous findings with respect to the comparative activity of the free ligand and its complexes. The result of an investigation of antimicrobial activity indicates that all the ligands show an inhibitory effect against all the...

The medicinal plant Jasminum flexile is reported in traditional medicine as an antidiabetic and anti-inflammatory agent. There is no scientific report on the antibacterial and anti-inflammatory activity of extracts of Jasminum flexile. This study investigated the antibacterial and anti-inflammatory potential of the hydroethanol extract of leaves of Jasminum flexile, its column fractions and constituent compounds. The column fractions MF14, MF9 and MF5 expressed a zone of inhibition of 12 mm against Streptococcus mutans and the isolated compound JFLC1 showed a zone of inhibition of 10 mm against Streptococcus mutans, Escherichia coli, and Klebsiella pneumoniae comparable to that of the standards ampicillin, kanamycin and chloramphenicol respectively at the same concentration. The highest anti- inflammatory potential was found for the column fraction MF3 (55.14%) as assessed from the percentage of haemolysis. The results reveal that the isolated compounds and extracts of leaves of Jasminum flexile possess significant antimicrobial and anti-inflammatory...

Introduction: Most human oro-facial infections originate from odontogenic infections, and prescribing antimicrobial has become a ubiquitous phenomenon. The World Health Organization (WHO) has recognized the inappropriate, indiscriminate and irrational use of antimicrobials leading to antimicrobial resistance. Aim & Objective: To assess the knowledge of antimicrobial resistance and antimicrobial prescription among dental practitioners in Chennai city. Materials and Methods: A total of 110 registered dental practitioners participated in this cross-sectional study. A pre-validated and self-administered questionnaire was prepared and distributed to the registered dental practitioners in Chennai city to collect the demographic details and the information regarding knowledge and practice towards antimicrobial resistance and an antimicrobial prescription for the most common oral conditions and commonly prescribed antimicrobials for their patients were obtained. Statistical analysis. The data were statistically analyzed by using the Statistical Package for the Social Science version 20.0. Descriptive statistics were performed, and a Chi-square test was done to assess the association between knowledge and practice of BDS and MDS participants. Results: 79.66% of BDS and 92.16% of...

Background and Objectives: This study was carried out with the objective to investigate the antibacterial and antifungal activity of the bark of Hardwickia binata Roxb. Materials and Methods: Methanolic extract of bark of Hardwickia binata Roxb. exhibited an inhibitory effect towards the pathogenic organisms. Antimicrobial activity the zone of inhibition values of methanolic extract of bark of Hardwickia binata Roxb. in against two Gram-positive microorganisms viz. Staphytococcus aureus and Bacillus subtilis and two Gram negative microorganisms viz. Escherichia coli and Pseudomonas aeruginosa showed significant activity. Antifungal activity of methanolic extract of bark of Hardwickia binata Roxb. in against two microorganism, Candida albicans, and Aspergillus niger, showed significant activity. Results: The results showed that the remarkable inhibition of the bacterial growth was shown against the tested organisms. The phytochemical analyses of the plants were carried out. The microbial activity of the Hardwickia binata was due to the presence of various secondary metabolites. Conclusion: Hence, these plants can be used to discover bioactive natural products that may serve AS leads in...

Dental caries is considered one of the major oral health issues throughout the world. Synthetic drugs and antibiotics have major side effects and can develop resistance. Ficus benghalensis F. benghalensis is a plant with enormous established pharmaceutical properties. The present study was designed to evaluate the antimicrobial activity of water, and ethanolic extracts of F. Benghalensis leaves against human dental pathogens. The isolated dental pathogens are Streptococcus mutans, Lactobacillus, Klebsiella pneumonia, and Candida albicans. The cup plate method was used to evaluate the antimicrobial activity of water, and ethanolic extracts of F. benghalensis leaves against the isolated microbes. Data were analyzed in one-way variance analysis. The water extract of F. benghalensis leaves was active against Klebsiella pneumonia and Candida albicans. The ethanolic extract of F. benghalensis leaves was active against all the Streptococcus mutans, Lactobacillus, Klebsiella pneumonia and Candida albicans. Since both the water and ethanolic extracts of F. benghalensis leaves shows maximum antimicrobial activity against Klebsiella pneumonia with a diameter of inhibition zones 20 mm and 23 mm...
