Oxidative cleavage of arachidonate (C(20)) and linoleate (C(18)) phospholipids generates truncated C(8) or C(12) gamma-hydroxyalkenal phospholipids as well as C(5) or C(9) carboxyalkanoate phospholipids, which are abundant in atherosclerotic plaques. The gamma-hydroxyalkenals promote foam cell formation by scavenger receptor CD36-mediated

The National Toxicology Program is conducting a chemical class study to investigate the structure-activity relationships for the toxicity of alpha,beta-unsaturated ketones. Ethyl vinyl ketone (EVK) was selected for study because it is a representative straight-chain aliphatic alpha,beta-unsaturated ketone with extensive

The mutagenic and genotoxic effects of ethylvinyl ketone were investigated. This alpha, beta-unsaturated carbonyl compound is widely distributed in the environment, in particular in food. Whereas ethylvinyl ketone shows only weak genotoxicity in the SOS Chromotest with Escherichia coli PQ37

A general approach for the synthesis of 3,5-diarylcyclopentenones was developed. Key aspects of this approach are the intramolecular Friedel-Crafts-type cyclization of vinyl chlorides and subsequent Pd-catalyzed cross-coupling reactions. The requisite vinyl chloride-bearing arylacetic acid precursors are readily available by straightforward

The title compound, C18H19N3O2, was obtained by an azo-coupling reaction with enaminones and is composed of a planar azoenamine skeleton which forms a six-membered ring through a symmetrical intramolecular hydrogen bond. The compound was found to exist as an equilibrium
