The first step in catabolism of the broadleaf herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) is catalyzed by 2,4-D/alpha-ketoglutarate (alpha-KG)-dioxygenase (TfdA) in Ralstonia eutropha (formerly Alcaligenes eutrophus) JMP134. This oxygen- and ferrous-ion-dependent enzyme couples the oxidative decarboxylation of alpha-KG (yielding CO2 and succinate)
A novel series of potent and selective PPARdelta agonists, para-alkylthiophenoxyacetic acids, was identified. The synthesis and structure-activity relationships are described.
A structurally representative series of 1,2- and 1,3-cyclic sulfamidates react with enolates derived from methyl alpha-phenylthioacetate 9b to give 5- and 6-substituted alpha-phenylthio lactams 20-24. These products provide, via the corresponding sulfoxides, an entry to alpha,beta-unsaturated lactams e.g. 12, 27

The existence of two or more enzyme forms with paraoxonase activity has been reported in sheep, rabbit, human and rat serum and recently in mouse and rat liver. In this study we describe the presence of two peaks with paraoxonase
