Abstract：
:The interaction of beta-cyclodextrin with a series of structurally related chiral thromboxane antagonists was investigated using NMR and RP-HPLC. HPLC studies used both a cyclodextrin bonded phase (Cyclobond I), and beta-cyclodextrin as a mobile phase additive with an achiral C8 column. Many of the compounds exhibited chiral recognition with beta-cyclodextrin in each technique, but only partial correlations between the three data sets were observed. HPLC and ROESY NMR data suggested the possibility of bimodal inclusion.
