Abstract

We report herein, design and synthesis of vinylaminophosphonates, a novel class of compounds as possible cysteine protease inhibitors. The synthesis of vinylaminophosphonates has been accomplished employing Tsuji-Trost reaction as a key step. The synthesized compounds were assayed against papain, a model cysteine protease and some of our synthesized compounds showed IC(50) values in the range of 30-54 μM thereby suggesting that these chemical entities thus could constitute an interesting template for the design of potential novel protease inhibitors.
