Lysine-based dendrimer with double arginine residues

Year: 2019

Type: article

Abstract: relaxation data for Lys-2Arg and Lys-2Lys dendrimers showed that the replacement of double Lys residues with double Arg residues resulted in a sharp decrease in the mobility of methylene groups in side segments and in the main chain of ε-Lys inner segments. We suggest that this unexpected effect is caused by a guanidine-guanidine pairing effect in water, which leads to entanglements between dendrimer branches.
