Aims: The aim of the study was to assess the antibacterial effect of Ficus carica extracts against Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, & Staphylococcus aureus. Study Design: Evaluation of antimicrobial activity using Cup-cut agar method. Place and Duration of Study: Microbiology Research Laboratory, Department of Microbiology and Immunology, Faculty of Pharmacy, University of Tripoli, from October 2015 to March 2016. Methodology: The leaves and stem part extracts of Ficus carica plant were prepared using maceration method. The antibacterial activities of the extracts were evaluated using Cup-cut agar method to determinate inhibitory zone diameters in millimeters of the plant extracts against Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa. The measurement of exponential bacterial growth curves was used to determine the type of growth pattern spectrophotometrically at 600 nm. Furthermore, plate count methods were also used to enumerate the bacterial count and to determine the percentage of inhibition as well as IC50. Results: The results of this study showed that Ficus carica extracts used, exhibited antimicrobial activity against Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Staphylococcus aureus. The maximum zone of inhibition against S. aureus (27± 0.04mm, p

The antibiotic elansolid C1 (8) was isolated from Chitinophaga sancti strain FxGBF13 after fermentation in the presence of anthranilic acid. Remarkably, 8 was also obtained by addition of anthranilic acid to a crude fermentation extract containing the macrolide elansolid A2 (1*). This Michael-type conjugate addition allowed us to generate 21 new derivatives of elansolid C1 (9-29) by using various nucleophiles. Biological activities of all derivatives were evaluated against Staphylococcus aureus, Micrococcus luteus, and the mouse cell line L929. arabic 9 English 74

Six new naphthalenone derivatives, balticols A-F and the known metabolite altechromone A were isolated from the AcOEt extract of the culture broth of fungal strain 222 belonging to the Ascomycota, which was found on driftwood collected at the coast of the Greifswalder Bodden, Baltic Sea, Germany. All structures were elucidated on the basis of NMR spectroscopic data and mass spectrometric analyses. The balticols were found to exhibit inhibitory activity against influenza virus A and herpes simplex virus. The most potent antiviral activity was observed for balticol E with an IC(50) value of 0.01 microg/ml against Herpes simplex virus type I. arabic 14 English 83
