Abstract:
A high-performance liquid chromatographic (HPLC) support was prepared, based on silica beads coated with a beta-cyclodextrin-containing polymer, which allows the elution of solutes in order of their affinity for beta-cyclodextrin. Binding constants were determined from the retention data for drugs eluted with pure buffer on the new support and good agreement was observed with results obtained by the Hummel and Dreyer method, previously used in HPLC studies of drug-protein interactions.
