The invention relates to a compound of the formula (I): in which k and j are independently 0 or 1, Y is a macrocycle in which the cycle includes 9 to 36 carbon atoms and is functionalised by three amino functions and by a chain for attaching the spacer arm Z via an X bond, Rc is a binding pattern with a receptor of the TNF superfamily, X is a chemical function for binding the Y group to the space arm, and Z is a bi-, tri- or tetra-functional spacer arm.

The hydrolysis of N-(β-cyanoethyl)-N'-(β-salicylideneaminomethyl)piperzine in the presence of hydrochloric acid leads to the formation of N-(β-carboxyethyl)-N'-(β-aminoethyl)piperazine, from which N-(β-carboxyethyl)-N'-(biscarboxymethyl-aminoethyl)piperazine is produced by the action of monochloroacetic acid.Under analogous conditions the hydrolysis of N-carboxymethyl-N'-(β-salicylideneaminoethyl)piperazine with concentrated hydrochloric acid followed by cyanoethylation of the product and hydrolysis gave N-carboxymethyl-N'-(di-β-carboxyethylaminoethyl)piperazine.
