The design, synthesis and anti-mycobacterial activities of 23 conformationally-constrained indeno[2,1-c]quinolines against Mycobacterium tuberculosis H37Rv is reported. Based on a structural comparison with the anti-TB TMC207 we have devised a synthetic methodology for making new conformationally-constrained indeno[2,1-c]quinoline analogs (Fig. 1), by retaining the biologically significant quin...
INTRODUCTION The occurrence of multi-antibiotic resistance among enterococci is a prevalent clinical problem worldwide and continues to get serious due to the lack of efficient therapeutic options by the time. In this regards, prokaryotic antimicrobial peptides with bactericidal or bacteriostatic activity which are directed against bacterial strains closely related to producer strains looks one...
METHANOLIC EXTRACT OF OLEORESINS OF ARAUCARIA BIDWILLI HOOK: and aerial parts of Cytisus scoparius Linn. Were screened for antimicrobial activity against two bacterial strains-Bacillus subtilis (Gram Positive) and Escherichia coli (Gem negative), and two fungal strains - Candida albicans and crytococcus neoformans by two-fold serial dilution technique. The results showed that all the microorgan...
A library of 53 benzimidazole derivatives, with substituents at positions 1, 2 and 5, were synthesized and screened against a series of reference strains of bacteria and fungi of medical relevance. The SAR analyses of the most promising results showed that the antimicrobial activity of the compounds depended on the substituents attached to the bicyclic heterocycle. In particular, some compounds...
Bioactivity-guided fractionation of an antimicrobial active extract from twigs of Baccharis retusa C. DC. (Asteraceae) yielded the flavanone 5,4'-dihydroxy-7-methoxy-flavanone (sakuranetin) as responsible for the detected activity. The structure of the bioactive compound was established on the basis of spectroscopic data analysis, including NMR and MS. Additionally, the structure of a new cryst...
INTRODUCTION The broth microdilution method (BMD) for testing telavancin minimum inhibitory concentrations (MICs) was revised (rBMD) in 2014 to improve the accuracy, precision, and reproducibility of the testing method. The aim of this study was to determine the effect of the revised method on telavancin MIC values for Staphylococcus aureus (S. aureus) clinical isolates obtained from hospital-a...
Amphipathic α-helical antimicrobial peptides comprise a class of broad-spectrum agents that are used against pathogens. We designed a series of antimicrobial peptides, CP-P (KWKSFIKKLTSKFLHLAKKF) and its derivatives, and determined their minimum inhibitory concentrations (MICs) against Pseudomonas aeruginosa, their minimum hemolytic concentrations (MHCs) for human erythrocytes, and the Therapeu...
PURPOSE In this study the effects of small systematic MLC misalignments and gravitational errors on the quality of Rapidarc treatment plan delivery are investigated with respect to verification measurements with two detector arrays and the evaluation of clinical significance of the error-induced deviations. METHODS Five prostate and six head and neck plans were modified by means of three erro...
The results of vancomycin susceptibility tests document that the drug continues to have activity against a wide variety of gram-positive pathogens. The subsequent emergence of vancomycin-resistant enterococci, the persistent failure of vancomycin therapy against strains tested as susceptible, and the more recent discoveries of vancomycin-intermediate or -resistant Staphylococcus aureus strains ...
The in-vitro activities of six newer cepl~alosporins against 459 recently isolated strains of Gram-negative bacilli were determined using an agar dilution method to establish minimum inhibitory concentrations (mics). The cephalosporins tested were cefotaxime, moxalactam,cefoperazone, ceftriaxone, cefsulodin and ceftazidio~e. The strains tested included Enterobacteriaceae, Pscudornorlas aerugims...
