The invention relates to a method for activating regulatory t-cells (Treg-cells) of the human or animal body, comprising a step of bringing into contact the regulatory t-cells (Treg-cells) in a suitable liquid medium with one or a plurality of inhibitors of alanyl-amino peptidase (amino peptidase N; APN) and/or with one or a plurality of inhibitors of peptidases with the same substrate specificity to induce a suppressive effect of the regulatory t-cells (Treg-cells).

Full details are given for the syntheses of the proteaseinhibitors, poststatin and eurystatin by the acyl cyanophosphorane coupling procedure used for the formation of α-keto amides. We have also extended this methodology to the syntheses of the related α-hydroxy amide natural products, phebestin, probestin and bestatin. The key step in the latter synthetic sequences involved diastereomeric selectivity
