The present invention relates to a novel class of diagnostically or therapeutically effective compounds comprising novel peptides able to bind fibrin, to a process for their preparation and to compositions thereof for use in therapy and diagnostics. The compounds of the invention bind, in particular, to fibrin present in the extracellular matrix (EC) of tumor or connective tissue of stroma thus acting as targeting moieties able to bring and successfully bound an active moiety linked thereto to fibrin depositions inside solid tumors.
dro‐1,4‐diazepine tetra acetic acid) derivatives functionalized with short (C2 and C4) n‐alkyl acidfunctions are reported. The carboxylate functionality is the site for further conjugations for the design of more specific contrast agents (CAs). Interestingly, it has been found that the synthesized complexes display enhanced properties for use as MRI contrast agents on their own. The stability constants
