| abstract |
The invention relates to peptide derivatives (peptides and pseudopeptides) and their use as vectors for substances of interest to the user. The invention also relates to conjugates containing a peptide derivative of the invention, combined with a substance of interest to the user. The peptides according to this invention can be used for vector transfer in the form of conjugates, as a rule, precursors ("prodrugs") of those substances of pharmaceutical or diagnostic interest, for example therapeutic, imaging or diagnostic agents or molecular probes across cell membranes, in particular with facilitate their transfer across the blood-brain barrier. |
