In this study, a quinoline-4-carboxylic acid derivative was synthesized through Pfitzinger reaction. reaction, isatin is modified via its reaction with ketone and refluxed for 24 h to obtain acid. The presence of carboxylic group identified by Fourier Transform Infrared (FTIR) spectroscopy ultraviolet–visible (UV-Vis) spectrophotometry. results showed that the absorption peaks C=O O–H stretchin...

in the present study, four carbon sources were tested for the polyester synthesis of pseudomonas aeruginosa pa01 which is a ubiquitous environmental bacterium and is one of the top three causes of opportunistic human infections. these included linear c8 to c11 carboxylic acids. octanoic acid, nonanoic acid, decanoic acid and undecanoic acid were added to m1 minimal medium to final concentration...

The triggering of antibiotic production by various environmental stress molecules can be interpreted as bacteria's response to obtain increased fitness to putative danger, whereas the opposite situation - inhibition of antibiotic production - is more complicated to understand. Phenazines enable Pseudomonas species to eliminate competitors for rhizosphere colonization and are typical virulence f...

3-Carbamoylmethyl-Indole-1-Carboxylic Acid Ethyl Ester (an ethoxycarbonyl derivative of indole-3-acetamide) is obtained by Friedel–Crafts type cyclocondensation γ-functionalized acetoacetamide in neat polyphosphoric acid.

The fate and impact of Pseudomonas aureofaciens TX-1 following application as a biocontrol agent for fungi in turfgrass were studied. The organism was applied with a modified irrigation system by using a preparation containing 1 x 10(6) P. aureofaciens TX-1 CFU ml(-1) about 100 times between May and August. We examined the impact of this repeated introduction of P. aureofaciens TX-1 (which is k...

Single crystal X-ray diffraction analyses of the 2 : 1 complexes of phenazine with hydroquinone and 1,5-dihydroxynaphthalene and the 3 : 1 complex of phenazine with 4,4 ́-dihydroxybiphenyl have been performed. It is shown that in these complexes and also in the 3 : 1 complex of phenazine with 5,10-dihydrophenazine, phenazine forms a host framework consisting of onedimensional channels. The varia...

Thermal analysis of acrylonitrile/acrylic acid P(AN/AA) copolymer films containing 5%, 10% and 20% acrylic acid dendrigrafted with citric acid (CA) is examined using differential scanning calorimetry (DSC) with various heating rates, thermogravimetry (TGA) and derivative thermogravimetric analysis (DTG). Also, the effect of carboxylic acid on thermal stabilization of the P(AN/AA) copolymers, wh...

Optical resolution of racemic 5-oxo-1-phenyl-pyrazolidine-3-carboxylic acid 2 with L-amino acid methyl ester via the diastereomers formation was investigated. Treatment of racemic 5-oxo-1-phenylpyrazolidine-3-carboxylic acid 2 with L-valine methyl ester gave diastereomers with a total yield of 86%. The diastereomeric dipeptides can be easily separated by flash column chromatography. Acidic clea...

Ethyl 2,3-diendo-3-aminobicyclo[2.2.2]oct-5-ene-2-carboxylate ((±)-1) was resolved with O,O'-dibenzoyltartaric acid via diastereomeric salt formation. The efficient synthesis of the enantiomers of 2,3-diendo-3-aminobicyclo[2.2.2]oct-5-ene-2-carboxylic acid ((+)-7 and (-)-7), 3-endo-aminobicyclo[2.2.2]oct-5-ene-2-exo-carboxylic acid ((+)-5 and (-)-5), cis- and trans-3-aminobicyclo[2.2.2]octane-2...
