a series of curcumin derivatives containing heterocyclic moiety have been synthesized and evaluated for their antibacterial activities. the chemical structures of the synthesized compounds were verified on the basis of spectral data and elemental analyses. investigation of antimicrobial activity of the derivatives demonstrated the ability to inhibit gram-positive microorganisms with zone of inh...

The present study was aimed to evaluate the phytochemical constituents and antibacterial activity of the flower extracts of Albizia lebbeck, Cordia sebestena, Thunbergia grandiflora and Antigonon leptopus. Preliminary phytochemical screening was done by the standard methods described by Harborne. Antibacterial study was carried out by disc diffusion method. The results of the phytochemical anti...

During the present study the antibacterial activity of Morinda citrifolia leaf, fruit and seed extract was assessed in-vitro by using disc diffusion method. A total of five different accessions of M. citrifolia plants were randomly selected and screened for antibacterial activity against five different bacterial pathogens. Overall analysis of the antibacterial activity of various extracts revea...

In medicinal chemistry nitrogen containing heterocycles are the most important compounds which show various biological activities. The cinnoline are nitrogenous derivatives and found to elicit many pharmacological actions like anti-hypertensive, antithrombotic, antihistamine, antileukemic, CNS activity, anti tumor, antibacterial and antisecretory activity. We planned to synthesis new series of ...

Padi straw (Oryza sativa) is one type of stem produced from padi tree trunks. Antibacterial activity testing was carried out by agar diffusion method using paper disc as a backup observing the formation clear zone indicating presence antibacterial activity. Variations in concentration extract test solution were made with %w/v ratio between 100% pure and DMSO adjusted at various concentrations, ...

The use of herbal decoctions in treating wound infections is increasing especially in developing countries including Nigeria. The increasing incidence of wound infections, coupled with the scarce foreign exchange to import potent antibiotics into the country and the inherent capacity of the wound pathogens to resist the therapeutic effects of such antibiotics have necessitated the use of altern...

Rheum ribes is among the Polygonaceae family which is endemic in Iran and a few neighboring countries. In this investigation, antibacterial effects of root, stalk and leaves extracts of Rheum ribes on a few common clinical isolates of gram negative pathogens were studied, using the cup plate and paper disc methods. Gram negative microorganisms studied were Escherichia coli, Klebsiella pneumonia...

The present study aimed to evaluate antimicrobial activity of tigecydcline against 84 multidrug resistant (MDR) Acinetobacter spp. strains by disc diffusion and E-test methods. The results of disc diffusion test were compared according to two different interpretation ways. In addition, E-test results and the disc diffusion results that interpreted by both the methods were checked for compatibil...

background and objective: nowadays, incidence of antibiotic-resistance among pathogenic bacteria has increased due to indiscriminate use of antimicrobial drugs for treatment of diseases, especially urinary tract infections. medicinal plants are also of great importance as antibacterial agents. therefore, the aim of this study was to determine the antibacterial effect of ethanolic extract of net...

Seventeen Indian folklore medicinal plants were investigated to evaluate antibacterial activity of aqueous, ethanol and acetone extracts against 66 multidrug resistant isolates of major urinary tract pathogens (Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Enterococcus faecalis) by disc diffusion method. Ethanol extract of Zingiber officinale and Punica granatum showed str...
