Objective: To study the chemical profile, antimicrobial properties, and synergistic effect with known antibiotics of essential oil extracted from marine red macroalgae Centroceras clavulatum (C. Agardh) Montagne, collected in Morocco.Methods: The composition was analyzed by gas chromatography-mass spectrometry. evaluated for antibacterial (Pseudomonas aeruginosa, Escherichia coli, Bacillus subt...

(pyrazol-3-yl)pyridmium group at the C-3' position as a combination of the pyridine moiety of ceftazidime2) and the pyrazole moiety of cefoselis3) to attain a synergic effect in activity. As we expected, those compoundsexhibited wellbalanced and broad spectrum of activity against Grampositive and Gram-negative bacteria. Of them, 7-[(Z)-2-(2aminol ,3-thiazol-4-yl)-2-(methoxyimino)acetamido]-3[(3...

We have identified a natural clay mixture that exhibits in vitro antibacterial activity against a broad spectrum of bacterial pathogens. We collected four samples from the same source and demonstrated through antibacterial susceptibility testing that these clay mixtures have markedly different antibacterial activity against Escherichia coli and methicillin-resistant Staphylococcus aureus (MRSA)...

The antibacterial activity against Staphylococcus aureus of long-chain fatty alcohols was investigated, with a focus on normal alcohols. The antibacterial activity varied with the length of the aliphatic carbon chain and not with the water/octanol partition coefficient. 1-Nonanol, 1-decanol and 1-undecanol had bactericidal activity and membrane-damaging activity. 1-Dodecanol and 1-tridecanol ha...

three extracts of pulicaria dysenterica were examined for antibacterial activity using the agar disk-diffusion method against six bacterial strains. some of these extracts were found to be active against some bacterial strains. the methanolic extract exhibited a superior level of antibacterial activity. all of the extracts were active against vibrio chlorea.

some n¬-acyl-n'-aryl thiourea derivatives 4(a-f) have been prepared by the reaction of acyl halides ammonium thiocyanate and aryl amines. the structures of synthesized compounds have been characterized by ir, 1hnmr spectral studies. the synthesized compounds 5(a-f) have been screened for antibacterial activity. the effect of the structure of the investigated compounds on the antibacterial activ...

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 ...

In the study were presented data for comparison of antibacterial activities between long time stored acacia (Robinia pseudoacacia L.), multifloral and oak (Quercus spp.) honeydew honeys towards Staphylococcus aureus (ATCC 9144). The results showed that the antibacterial activity of oak honeydew and multifloral honeys was much higher in comparison with acacia honeys with the lowest antibacterial...
