Isolated from pig liver as a crude, inhomogeneous enzyme fraction, pig liver esterase (PLE) was found to metabolize a wide range of substrates; often in a highly stereoselective manner. This crude esterase preparation, however, contains several iso-enzymes at proportions varying

A reagent controlled organocatalytic enantioselective chlorolactonization reaction has been developed. Several 4-aryl pentenoic acids were cyclized in the presence of 0.1 equiv of (DHQD)(2)PHAL, employing various N-chlorinated hydantoins as the terminal chlorenium source. Ten examples are presented with selectivities ranging

4-Pentenoate (4P) is a short-chain fatty acid which causes a complete renal Fanconi syndrome. We have examined the mechanism of 4P toxicity along the nephron after a prolonged (30 min) exposition of isolated renal tubular segments to this agent. In

Fanconi's syndrome was investigated using brush border membrane (BBM) vesicles isolated from dog kidney. Sodium-dependent uptake of glucose, phosphate, and amino acids and protein phosphorylation were studied in BBM isolated from normal and from 4-pentenoate- and maleate-treated animals. The time
