Intestinal absorption and enterohepatic circulation of N-formyl-methionyl-leucyl-125I-tyrosine, a bioactive synthetic analog of the bacterial chemotactic peptide N-formyl-methionyl-leucyl-phenylalanine has been investigated in the rat. In ileum and proximal and distal colon, dithiothreitol, which increases mucosal permeability, increased peptide absorption and biliary

Based on the SAR of glinide agents, mitiglinide has been modified to study the SAR of glinides. a-Benzylsuccinic acid derivatives which were designed and synthesized in order to find some more hypoglycemic active agents and further investigate the SAR of

Benzylsuccinate synthase catalyzes a highly unusual reaction: the addition of toluene to fumarate to form (R)-benzylsuccinic acid. The stereochemistry of this reaction has been examined using [d3-methyl]toluene and either fumarate or its cis stereoisomer, maleate, as the substrates. We demonstrate
Arphamenine A was synthesized in a cell-free system obtained from the arphamenine-producing strain, Chromobacterium violaceum BMG361-CF4. L-[14C]-phenylalanine was converted to beta-phenylpyruvic acid by phenylalanine amino-transferase obtained from the 10,000 x g supernatant (S10 fraction). [14C]-Benzylmalic acid was synthesized from beta-phenylpyruvic
