Fluorescein-labeled oligodeoxynucleotides (ODNs) from automated synthesis commonly produce multiple peaks in high performance liquid chromatography (HPLC) chromatograms. We found that these peaks are due to chemical modifications of the ODNs instead of the common perception of isomers. To identify the

Tannery workers are at considerable risk of developing occupational contact dermatitis. Occupational skin diseases in tannery workers in newly industrialized countries have been reported, but neither the prevalence of occupational allergic contact dermatitis nor the skin-sensitizing agents were specifically examined

1. The enzymic C-oxygenation of N,N'-diphenylguanidine (DPG) to N-(4-hydroxyphenyl)-N'-phenylguanidine (4HPG) and the N-oxygenation of N,N'-bis-(pentafluorophenyl)-guanidine (BPG) to N"-hydroxy-N,N"-bis-(pentafluorophenyl)-guanidine (HBPG) is reported. 2. The metabolites were identified by t.l.c. and mass spectral analysis using synthetic reference compounds. 3. Rat and rabbit

A series of dibenzo[a,d]cycloalkenimines were evaluated for their affinity to the (+)-5-methyl-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imine (MK-801) binding site in Caenorhabditis elegans membranes and their nematocidal activity. The (+)-MK-801 enantiomer (1) had a higher affinity (Kd = 240 nM) for its specific binding site
