The Southampton Seven are: Tetrazine (E102), Quinoline
yellow (104), Sunset yellow (110), Carmoisine (E122), Ponceau 4R (E124), Allura red (E129), and the preservative Sodium Benzoate (E211).
Nine monoterpenoid indole alkaloids; naucletine (1), angustidine (2), nauclefine (3), angustine (4), naucline (5), angustoline (6), harmane (7), 3,14-dihydroangustoline (8), strictosamide (9) and one quinoline
alkaloid glycoside; pumiloside (10) from Nauclea officinalis were tested for cholinesterase inhibitory activity.
falciparum multidrug resistance-1 copy number is also believed to reduce parasite sensitivity to some quinoline
antimalarials (typically an aminoquinoline) the partner drug of ACT (17-18).
ORs were positive but not statistically significant for the other exposures of a priori interest except quinoline
Enone 1 reacts under Michael conditions with malononitrile to give the quinoline
Affected sources are those facilities that generate or produce the following HAPs of concern above the OSHA thresholds: 1,3-butadiene, 1,3-dichloropropene, acetaldehyde, chloroform, ethylene dichloride, hexachlorobenzene, methylene chloride, quinoline
, hydrazine, and compounds of arsenic, cadmium, chromium, lead, manganese, and nickel.
Based on natural sources such as paprika, lutein and beta-carotene they represent an excellent natural alternative to the much-debated artificial colorants Sunset Yellow, Tartrazine and Quinoline
derivatives have been earlier used for a long time in the treatment of human amoebic dysentery and bacillary dysenteries (de Alencar and Sampaio, 1963; Heseltine and Campbell, 1960; Heseltine and Freeman, 1959).
Antimicrobial compounds which are water soluble and easily dispersible materials such as quaternary ammonium compounds, bisquanidine compounds, dialkyl quaternary compounds, quinoline
compounds, substituted phenols, chlorhexidine, didecyldimethyl ammonium chloride, and a mixture of these materials are generally employed .
Since a 2007 study conducted at the University of Southampton linked the artificial colourants sunset yellow, quinoline
yellow, carmosine, allura red, ponceau 4R and tartrazine--subsequently dubbed the Southampton Six--to increased hyperactivity in children, a prevailing sense of latent uneasiness has risen to the level of outright alarm.
