Abstract
The inclusion complex-forming ability of three glucosyl-cyclodextrins (CDs), 6-O-.alpha.-D-glucosyl-.alpha.-CD (G-.alpha.-CD), 6-O-.alpha.-D-glucosyl-.beta.-CD (G-.beta.-CD), and 6A,6D-di-O-.alpha.-D-glucosyl-.beta.-CD (2G-.beta.-CD) with slightly soluble or insoluble drugs in aqueous solution and in the solid state was studied by the solubility method, ultraviolet spectroscopy, and differential scanning calorimetry. These glucosyl-CDs were capable of forming inclusion complexes with compounds which can form complexes with the parent CDs. The enhancement of solubility of poorly water-soluble drugs by glucosyl-.beta.-CDs was much more marked than that by .beta.-CD. The hemolytic activity of glucosyl-CD was lower than that of each parent CD. The estriol-glucosyl-.beta.-CD complex may be practically applicable to injectable preparations because of its high water-solubility and low hemolytic activity.This publication has 4 references indexed in Scilit:
