Inclusion complexes of naphthalene (NP) with cyclodextrins (CD) have been investigated so far using non-NMR techniques resulting in inconsistent data. Here, the first application of high-field NMR spectroscopy in combination with a precise analysis o

Simple and convenient method of protein dynamics evaluation from the insufficient experimental 15N relaxation data is presented basing on the ratios, products, and differences of longitudinal and transverse 15N relaxation rates obtained at a single m

Complex formation between quinine and natural cyclodextrins (CD) was studied using NMR spectroscopy. The strongest association was observed for complexes of neutral quinine molecules with βCD. Association constants for monocationic quinine were one

The synthesis of new dermorphin analogues is described. The (R)-alanine or phenylalanine residues of natural dermorphin were substituted by the corresponding α-methyl-β-azidoalanine or α-benzyl-β-azido(1-piperidinyl)alanine residues. The potency

Nuclear magnetic relaxation provides a powerful method giving insight into molecular motions at atomic resolution on a broad time scale. Dynamics of biological macromolecules has been widely exploited by measuring (15)N and (13)C relaxation data. Int
