We have developed a rapid, simple and precise high-performance liquid chromatographic (HPLC) method using an UV detection system for the determination of new anti-HIV candidates, nineteen KR-V compounds, in rat plasma. We used a analytical columnn of C_(18) (5 §­, 250 ¡¿ 2.0 §® ID.) and a mobile phase of water and ACN mixture (40/60, v/v). Under these conditions, all the KR-V compounds were readily separated from plasma with retention times of 4-12 min. The limits of quantitation for the 19 KR-V compounds were 15-30 ng/§¢. The recoveries from the plasma were higher than 85% (C.V<10%) with exception of KR-V 2, 7 and 15. The compounds KR-V 2, 7 and 15, containing ester moieties, were found to be unstable in plasma. This result suggests that esters, like KR-V 2, 7 and I5, should be excluded from future structure design studies of anti-HIV KR-V agents. In conclusion, the current HPLC method is a valuable analytical tool for investigating the pharmacokinetics of the KR-V series in rats.
