Dissolution of diclofenac from compressed discs containing mixtures of a diclofenac salt and a basic excipient, in various w/w ratios, was examined. Two diclofenac salts, diclofenac deanol (DDNL) and diclofenac tert-butylamine, and the basic excipient 2-amino-2-methyl-1,3-propanediol (AMPD) were examined. Inclusion

The inhibitory effect of inorganic phosphate on the activity determination of isoenzymes of alkaline phosphatase (AP) in diethanolamine (DEA), glycine and 2-amino-2-methyl-1,3-propandiol (AMPD) buffer was studied. This effect depends on the buffer used and isoenzyme investigated. Especially the placental isoenzyme

Dirhodium(II)-catalyzed C-H amination reaction of (S)-3-(tert-butyldimethylsilyloxy)-2-methylpropyl carbamate, which was easily prepared from methyl (S)-2-methyl-3-hydroxypropanoate, proceeded more smoothly than those of their 2-(methoxycarbonyl)propyl derivative to give the corresponding oxazolidinone in excellent yield. The resulting oxazolidinone was converted efficiently into both (R)-monoprotected
