Abstract

Abstract

Objective: The aim of this study was to synthesize new modified Cyclodextrins (CDs), for study of inclusion complex of drug with CD to improve water solubility.

Methods: In this study, the formulation of bioactive molecules (Baclofen®, aziridine synthesis and active propolis) with amphiphilic cyclodextrin (β-CD-amph) was prepared from native β-cyclodextrin (β-CD) via the simple co-precipitation method at the University of Tlemcen, Algeria (2016).

Results: It was of interest to find a model of molecule derivatives that would be sufficiently water-stable and form a stable complex with (β-CD-amph) in aqueous medium, so that it could be used as a reference in future formulations or vectorization work. Among the nanoformulation, NMR studies of the inclusion complex of this derivative with b-cyclodextrin provided useful parameters related to the stoichiometry of the complex and the association with stant Ka. 

Conclusion: The geometry of the complex was assessed by 2D-ROESY experiments, suggesting a deep insertion of the guest into the cavity of (β-CD-amph).
