제목 Binding Study of (S)-perillyl alcohol and Human Serum Albumin using high-performance frontal analysis
초록 Quantitative investigation of drug-binding is essential in pharmacokinetic study and clinicial applications. Equilibrium dialysis and ultrafiltration followed by HPLC analysis methods have been widely used for this purpose. However, there conventional analytical methods suffer some limitations. To overcome this problem, high-performance frontal analysis(HPFA), a chromatographic method which allows simple and easy determination of unbound drug concentrations after direct sample injection has been reported.
Here we present the protein analysis of (S)-perilly alcohol by HPFA. The analysis was performed on a Develosil 100-Diol-5 (10 cm x 4.6 mm I.D.) column, sodium phosphate solution (pH 7.4, ionic strength 0.17) was used as the mobile phase at a flow rate of 1ml/min. Optimum ultrawavelength was set on 205nm. A injection volume of 600 ㎕ was chosen to ensure the drug to be eluted as zonal peal with a plateau. By Scatchard analyses, it was found the binding constant (K) and binding site (n) of perillyl alcohol on HSA were: K=5.20x106[m-1], n=0.00335, respectively.
