Abstract: NMR spectroscopy has been a powerful tool for structural characterization and property study of molecules, especially for biopolymers. Dendrimers are unique type of synthetic macromolecules with a cascade hyper-branched structure and spherical shape if perfectly generated. Classic 1D 1H and 13C NMR techniques have been heavily utilized for dendrimer structural verification after the synthesis. This review focuses on the applications of special NMR techniques such as NMR relaxation time and diffusion measurements, multinuclear NMR spectroscopy, as well as multidimensional homo- and hetero-nuclear correlation spectroscopy for studying the structure, property and interactions of dendrimers.

Abstract: Prion disorders are fatal neurodegenerative diseases resulting in the formation of fibrils – amyloid-like structures.It has been shown that dendrimers possess antiprion activity. We checked different dendrimers in terms of generation (size) and chemical composition: carbosilane dendrimers with tertiary and quaternary amino groups on the surface and PAMAM dendrimers with the same functionalities. It turned out that dendrimer interior and end groups influenced fibril formation. For PAMAM dendrimers at low concentrations we observed the acceleration of fibril formation, whereas high concentrations completely inhibited the process. In the case of carbosilane dendrimers no acceleration was observed, but the inhibitory trend occurred for higher concentrations.

Figure 1. Kinetics of fibril formation in the presence of dendrimers that inhibited the process, and upon adding dendrimers that enhanced the fibril formation.
