초록

Ketoprofen과 Ibuprofen은 비스테로이드 계통의 진통 및 소염제로서 관절염 등을 위한 진통제나 해열제로 이미 널리 사용되고 있다. 그러나 이 두 물질이 치료약으로 사용될 때 (S)-ketoprofen과 (S)-ibuprofen은 약리학적으로 항염증 작용을 하며 (R)-ketoprofen과 (R)-ibuprofen은 약효가 없거나 부작용을 일으키는 문제점을 가지고 있다. 본 연구에서는 Ketoprofen과 Ibuprofen을 Kromasil HPLC 칼럼을 사용하여 이동상 조성비(hexane/t-BME/acetic acid)와 온도 변화($25{\sim}55^{\circ}C$)가 분리에 미치는 영향을 실험하였다. 분리특성은 선택도, 분리도, 이론단수 그리고 용량인자와 절대온도의 역수사이의 관계에서 계산된 엔탈피 변화 ${\Delta}H$에서 Ketoprofen과 Ibuprofen의 kromasil HPLC column 고정상과의 상호작용의 크기를 열역학적으로 검토하였다. 온도 $25^{\circ}C$, 이동상 조성비(hexane/t-BME/acetic acid) 80/20/0.1에서 선택도, 분리도, 이론단수 엔탈피 수치가 높게 나타났다.

Ketoprofen and ibuprofen are non-steroid anti-inflammatory drug(NSAID) that have analgesic and antipyretic properties. (S)-ketoprofen and (S)-ibuprofen have pharmacological activity, while (R)-ketoprofen and (R)-ibuprofen are either inactive or have side effect. The chiral separation of racemic ketoprofen and ibuprofen enantiomers was carried out by using a Kromasil HPLC column. Some chromatographic parameters (selectivity, resolution, number of theoretical plates and ${\Delta}H$) are calculated under different mobile phase compositions of hexane/t-BME/acetic acid and temperatures. The selectivity, resolution and number of theoretical plates were observed high at $25^{\circ}C$ and the composition of hexane/t-BME/acetic acid (80/20/0.1).
