Synthesis and biological screening of some novel amidocarbamate derivatives of ketoprofen.

A series of novel ketoprofen derivatives 4a-j bearing both amide and carbamate functionalities were prepared using benzotriazole. Selective reduction of ketoprofen produced hydroxy derivative 2, which reacts with one or 2 mol of 1-benzotriazole carboxylic acid chloride (1) gave benzotriazole derivatives 3a and 3b respectively. Antioxidative screenings revealed that the prepared compounds 3b and 4a-j possess excellent lipid peroxidation inhibition at 0.

Synthesis and biological evaluation of [1,2,4]triazino[4,3-a] benzimidazole acetic acid derivatives as selective aldose reductase inhibitors.

The acetic acid derivatives of [1,2,4]triazino[4,3-a]benzimidazole (TBI) were synthesized and tested in vitro and in vivo as selective aldose reductase (ALR2) inhibitors. Compound PS11 showed highest inhibitory activity (IC(50)) 0.32 microM and was found to be effective in preventing cataract development in severely galactosemic rats when administered as an eyedrop solution.
