During recent studies on development new inhibitor of thioredoxin system inhibitors, the new class of β-acyloxyamides I has been found. Studied peptidomimetics exhibited interesting biological properties and were very potent anticancer agents either in vitro (in cellular assays) or in vivo (mice model). [1,2]

Detailed mechanistic studies indicated, however, that compound I activates apoptotic pathways not only by inhibiting the thioredoxin system. To establish mechanism of action of new compounds in a cell, we developed marker compounds containing fluorescent fragments as well as biotinylated compounds 1 and 2. Here, we will present the proposed methodology as well as the results of studies on the synthesis of compounds 1 and 2.
