The molecules of 10-methyl-8-phenyl-11-(3-pyridyl)-6,8-dihydro-5H-benzo[f]pyrazolo[3,4-b]quinoline, C26H20N4, (I), are linked by a single C-H...N hydrogen bond into cyclic R(4)(4)(12) tetramers generated by a -4 axis. In isomeric 10-methyl-8-phenyl-11-(4-pyridyl)-6,8-dihydro-5H-benzo[f]pyrazolo[3,4-b]quinoline, (II), which crystallizes with Z' = 2 in space group P2(1)2(1)2, the two independent ...

A bacterial culture was isolated from oil-contaminated soil based on its ability to metabolize the quinoline as the sole source of nitrogen. In this research Bacillus licheniformis strain was identified based on the result of 16S rRNA analysis. Optimized conditions were obtained with full factorial experimental design method using design expert software at temperature: 32<...

The asymmetric unit of the title structure, C(28)H(19)NO·0.5C(3)H(6)O, comprises one 2-(anthracen-9-yl)-10-meth-oxy-benzo[h]-quinoline mol-ecule and an acteone mol-ecule with an occupany of 0.5. The solvent mol-ecule is disordered around a centre of symmetry. Its occupancy was determined from NMR data and kept fixed during the refinement. The two conjugated ring systems of the mol-ecule are alm...

Investigations into V-agent interaction with 1,10-phenanthroline nitrate Ln(III) complexes (Eu and Tb) were carried out using luminescence and UV-Vis spectroscopy. Addition of several equivalents of agent resulted in the loss of luminescence intensity and the observation of free 1,10-phenanthroline by UV-Vis. We propose a displacement mechanism in which the V-agent acts as a bidentate ligand to...

It has previously been demonstrated that phenanthroline-based ligands used to make gold metallotherapuetics have the ability to exhibit cytotoxicity when not coordinated to the metal center. In an effort to help assess the mechanism by which these ligands may cause tumor cell death, iron binding and removal experiments have been considered. The close linkage between cell proliferation and intra...
