Quinoline, a hepatocarcinogen in rats, and 23 quinoline derivatives were tested for mutagenic activity with the Ames Salmonella typhimurium assay. Quinoline, 5-hydroxyquinoline, and 8-hydroxyquinoline were mutagenic in strain TA 100 when Aroclor 1254-induced rat (male outbred Sprague-Dawley) liver homogenate was

A spectrophotometric assay has been devised to measure oxygen consumption non-invasively in intact murine red cells parasitized by Plasmodium berghei. The method uses oxyhemoglobin in the erythrocytes both as a source of oxygen and as an indicator of oxygen consumption.

Hydroxylation of polyaromatic compounds through cytochromes P450 (CYPs) is known to result in potentially estrogenic transformation products. Recently, there has been an increasing awareness of the importance of alternative pathways such as aldehyde oxidases (AOX) or N-methyltransferases (NMT) in bioactivation

The structure, infrared spectrum, and photochemistry of 5-hydroxyquinoline (5HQ) were studied by matrix isolation infrared spectroscopy, complemented by theoretical calculations performed at the DFT(B3LYP)/6-311++G(d,p) level of approximation. According to the calculations, the trans conformer of 5HQ (with the OH group
