Abstract

Biocatalysis is a methodology of growing importance among organic chemists aiming at the synthesis of bioactive compounds, resulting in the establishment of many successful synthetic protocols[1]. Main reason for this is an enormous selectivity of biocatalysts.

Tripeptides and tripeptide mimetics are widely investigated due to their biological activity. Among them, an anti-inflammatory agent 1, an antibiotic 2, and human rhinovirus 3C protease inhibitors can be found.

Tripeptides with C-terminal aldehyde group are of special interest. Compound 3 (Mg- 132) is a potent and selective inhibitor of 20S proteasome, which is often used as a reference in biomedical studies.

The results of our studies on the successful combination of mutlicomponent reactions with enzymatic transformations to the synthesis of bioactive tripeptide mimetics, will be presented [2,3,4].
