Summary
In questo lavoro di tesi è stato affrontato lo studio delle interazioni tra piccole molecole organiche cicliche e modelli di membrane cellulari, costituiti da fosfolipidi in acqua, mediante spettroscopia NMR ( Nuclear Magnetic Resonance). Tali sistemi si organizzano in fasi liquido cristalline lamellari ed esagonali inverse, delle quali sono state studiate le proprietà strutturali e dinamiche. Inoltre l'effetto su tali proprietà di piccole molecole organiche in funzione della loro concentrazione è stato investigato grazie allo studio di diversi nuclei (2H, 1H, 13C e 31P) e proprietà nucleari.
In this thesis some interactions between small cyclic organic molecules and cell membrane models, made of phospholipids in water, have been investigated by Nuclear Magnetic Resonance Spectroscopy (NMR). We studied the structural and dynamic properties of these systems, which organize themselves in liquid crystalline lamellar and inverse hexagonal phases. Indeed the effects of different concentrations of the small organic molecules on these properties have been investigated thanks to the study of several nuclei (1H, 2H, 13C and 31P) and nuclear properties.
