In order to determine the importance of the depsibond present in natural destruxins, we have investigated the replacement of this ester bond by an amidebond, leading to a new family of analogues. Synthesis of six specific members of this new class of compounds is reported. Since none of these cyclopeptides showed any biological activity, we undoubtedly proved that the depside group is a requisite
