The racemic product of the Betti reaction of 5-chloro-8-hydroxyquinoline, benzaldehyde and 2-aminopyridine was separated by chiral HPLC to determine which enantiomer inhibited botulinum neurotoxin serotype A. When the enantiomers unexpectedly proved to have comparable activity, the absolute structures of (+)-(R)-1 and (-)-(S)-1 were determined by comparison of calculated and observed circular d...

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 ...

8-Hydroxyquinoline derivatives are metal-binding compounds that have recently attracted interest as therapeutic agents for cancer therapy. In this scenario, we designed and synthesized three new glucoconjugates, 5,7-dichloro-8-quinolinyl-β-D-glucopyranoside, 5-chloro-8-quinolinyl-β-D-glucopyranoside and 2-methyl-8-quinolinyl-β-D-glucopyranoside and investigated their biological properties in co...

Multinuclear (1H and 13C) NMR, and Raman spectroscopy, combined with DFT calculations, provide detailed information on the complexation between U(vi) oxoions and 8-hydroxyquinoline-5-sulfonate (8-HQS) in aqueous solution. Over the concentration region studied, U(vi) oxoions (uranyl ions) form one dominant complex with 8-HQS in water in the pH range 3-6, a mononuclear 1 : 2 (metal : ligand) comp...

In this work, a steroidal gelator containing an imine bond was synthesized, and its gelation behavior as well as a sensitivity of its gels towards acids was investigated. It was shown that the gels were acid-responsive, and that the gelator molecules could be prepared either by a conventional synthesis or directly in situ during the gel forming process. The gels prepared by both methods were st...

Dinuclear rhenium(I) complexes having a fac-[Re(CO)3](+) moiety of general formula fac-[Re2(CO)6(hq)2] have been synthesized in excellent yield by reacting [Re(CO)5Cl] with Hhq in a ratio of 1 : 1 in toluene in an argon atmosphere. Here hq(-) is the deprotonated form of 5-phenylazo-8-hydroxyquinoline (Hhq(1)), 5-(2-naphthylazo)-8-hydroxyquinoline (Hhq(2)) and 5-(2-fluorineazo)-8-hydroxyquinolin...

A Pseudomonas sp. isolated from sewage by enrichment culture on quinoline metabolized this substrate by a novel pathway involving 8-hydroxycoumarin. During early growth of the organism on quinoline, 2-hydroxyquinoline accumulated as the intermediate; 8-hydroxycoumarin accumulated as the major metabolite on further incubation. 2,8-Dihydroxyquinoline and 2,3-dihydroxyphenylpropionic acid were ide...
