摘要:
The invention concerns a method for binding, in solution, at least a peptide composition and at least a lipophilic vector bearing an aldehyde function, the coupling comprising a step which consists in producing a hydrazone bond between the peptide compound and the lipophilic vector. The invention also concerns lipophilic vectors for use in this method, lipopeptides obtained by this method, uses of the lipopeptides for cell screening, and the applications of the invention, in particular for preparing targeting of an active principle of the peptide kind (for example hormone or neuropeptide) through physiological barriers such as cell membranes.
