In the title compound, C(27)H(18)Cl(2)N(2)O(2), the 2-chloro-quinoline and 6-chloro-quinoline rings are almost planar, with maximum deviations from their mean planes of 0.072 (1) and 0.044 (1) Å, respectively, for the Cl atoms. The inter-planar angle between these rings is 14.36 (5)°. The inter-planar angle between the 6-chloro-quinoline and phenyl rings is 66.00 (8)°. In the crystal, mol-ecule...

The object of this study was to identify the major active ingredients of the Chinese Traditional Medicine Jiang-Zhi-Ning (JZN) based on the high performance liquid chromatography (HPLC) profiles of plasma samples obtained from beagle dogs at different times after intragastric administration of JZN, crude JZN extracts, different extracted fractions, different subfractions of the active fraction ...

IT has been shown that 8-hydroxyquinoline is not toxic for Staphylococcus aureus unless traces of iron (or copper) are present in the medium (Rubbo, Albert and Gibson, 1950). It was next shown that a large excess of either iron or oxine prevented a rapid bactericidal action. This led to the hypothesis that oxine gained access to the cells as a complex having one atom of the metal bound between ...

In the title compound, C18H13F2NO2, the two rings of the quinoline system are fused almost coaxially, with a dihedral angle between their planes of 2.28 (8)°. The plane of the attached benzene ring is inclined to the plane of the quinoline system by 7.65 (7)°. The carboxyl-ate group attached to the quinoline system is in an anti-periplanar conformation. There is a short intra-molecular C-H⋯O co...

The title compound, C(24)H(22)N(2)O, was obtained in a two-step procedure from the corresponding 4-(2-iodo-phen-yl)quinoline. The quinoline system is approximately planar [maximum deviation from the least-squares plane = 0.021 (2) Å]. The planes of the quinoline system and the phenyl ring subtend a dihedral angle of 78.08 (8)°. In the crystal, pairs of mol-ecules are connected via a center of s...

A derivative of quinine formed in minced rabbit liver has been isolated by Kelsey et al. (I), and identified by Mead and Koepfli (2) as a carbostyril. Hence quinine is oxidized in liver with replacement of the hydrogen atom in position 2 of the quinoline ring by a hydroxy group. Analogous oxidation products are excreted by men receiving the four principal cinchona alkaloids. This change is impo...

Quinoline was used to probe the steric and electronic contributions to rates of aromatic oxidation of nitrogen-containing, multiring substrates by cytochrome P450 (P450) enzymes. The regioselectivity of the P450 oxidation of quinoline was determined experimentally by identifying and measuring the ratios of metabolites. The laboratory results were compared with those obtained computationally by ...

The crystal structures of di-chlorido-palladium(II), -platinum(II) and -rhodium(III) complexes containing 8-(di-phenyl-phosphan-yl)quinoline, (SP-4)-[PdCl2(C21H16NP)], (1) [systematic name: di-chlor-ido-(8-di-phenyl-phosphanyl-quinoline)-palladium(II)], (SP-4)-[PtCl2(C21H16NP)]·CH2Cl2, (2) [systematic name: di-chlorido-(8-di-phenyl-phos-phanyl-quinoline)-platinum(II) dichlorometh-ane monosolvat...
