Study of the Complexation of Thiowurtzine with Cyclodextrins
摘要
Abstract
The complexation ability of one of the new promising analgesics, thiowurtzine (TW), with a number of cyclodextrin (CD) host molecules was studied using electron and 1H NMR spectroscopy in methanol and confirmed by quantum-chemical and molecular dynamics calculations. Spectrophotometric and fluorescence titration methods determined the 1 : 1 stoichiometry and stability of the resulting complexes with γ-cyclodextrin derivatives (for TW@HP-γ-CD log K1:1 = 3.0).
