WebAug 28, 2024 · The Higuchi-Connors method was used to corroborate it. The Benesi-Hildebrand method fixes ligand concentration (cyclodextrin) to different solutions with variable amounts of the substrate, from one to five mM. The absorbance of the free ligand is measured, and then subtracted from the rest of the solution's absorbances levels (ΔA). WebThis was explained by the solubilization theory of Higuchi and Connors. The solubility analysis of the ternary drug/competitor/CyD systems may be particularly useful for determination of the stability constant of a drug whose physicochemical and spectroscopic analyses are difficult, because they can be calculated by monitoring the solubility ...
