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

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
Synthesis and SAR of para-alkylthiophenoxyacetic acids is described. Achiral compounds 30, 31 and 32 were identified as potent and selective PPARdelta agonists.

Catalytic parameters of human butyrylcholinesterase (BuChE) for hydrolysis of homologous pairs of oxo-esters and thio-esters were compared. Substrates were positively charged (benzoylcholine versus benzoylthiocholine) and neutral (phenylacetate versus phenylthioacetate). In addition to wild-type BuChE, enzymes containing mutations were used. Single
