Peptidinol adenylates were assembled by condensing the carboxyl group
of N-blocked peptides with the alkylamino group of leucinol 5' adenosi
ne phosphodiester. The latter was prepared as protected precursor from
adenosine and leucinol by phosphite chemistry. The title compounds, w
hich mimic aminoacyl adenylates, are designed to penetrate microorgani
sms via peptide permeases and to interfere with genetic translation.
