Derivatives of peptides from the TIPP (Tyr-Tic-Phe-Phe; Tic = 1,2,3,4- tetrahydroisoquinoline-3-carboxylic acidity) family comprising a guanidino (Guan) function instead of the N-terminal amino group had been synthesized in order to enhance their blood-brain hurdle permeability. in the stabilization of part string orientations of lipophilic residues from the binding site observed in the triggered type of… Continue reading Derivatives of peptides from the TIPP (Tyr-Tic-Phe-Phe; Tic = 1,2,3,4- tetrahydroisoquinoline-3-carboxylic
