초록

일반적으로 paclitaxel과 유사한 구조를 가진 복잡한 유도체의 분리나 최종 제품에서의 엄격한 규정 등으로 인하여 한 단계의 HPLC system으로 정 제하는 것은 상당히 어렵다. 이러한 이유로 두 단계 HPLC system으로 식물세포 배양액으로 부터 paclitaxel의 대량 정제를 수행하였다. 즉, 첫번째 단계에 서 reverse-phase HPLC column, 두번째 단계에서 normal­p phase HPLC column을 사용하여 최종 제품을 얻었다. 또한 최종 정 제 된 paclitaxel 내 에 포함되어 있는 불순물 profile 확 언, 함량 분석, 그리고 이들 물질들에 대한 분리, 정제 및 동 정을 실시하였다 이들 불순물들 중에서 0.1% 이상되는 것은 모두 6종 (side chain derivative, baccatin III, 10-deacetyltaxol, cephalomannine, taxane derivative, 7-epitaxol)이며 NMR과 MS를 사용하여 화학구조를 분석한 결과 이미 알려진 pacli­t taxel 유도체 또는 전구체와 동일한 물칠로 밝혀 졌다. 본 연구 결과는 결국 paclitaxel 생산을 위한 품질관리 (quality con­t tr이)와 허가를 위한 자료로 유용하게 사용되어 진다.

In developing a HPLC purification process, it was hoped that a single chromatographic system would be sufficient to abtain pure paclitaxel in high yield. However, no such system was found, due in part to the complex taxoid profile of crude paclitaxel and to the rigorous nature of the product specification. A two step HPLC purification was adopted using reverse-phase separation on C(sub)18 as a first step, and normal-phase separation on silica as the final polishing step. Impurity profiles were established and maintained for paclitaxel, which identified and quantified each impurity observed in purified paclitaxel from these two steps, all impurities at or above 0.1% were identified. Results provide information for improving the quality control of paclitaxel production.
