일일초잎과 모상근으로부터 추출한 Vindoline과 Catharanthine의 화학결합에 의한 Vinblastine 생산
Production of Vinblastine by Chemical Coupling of Vindoline Extracted from Cultivated Plants and Catharanthine from Hairy Root Cultures in Vinca(Catharanthine roseus)
Vinblastine, an anticancer agent was produced by chemical coupling of two different monomeric indole alkaloids, vinblastine and catharanthine in the presence of ferric ion. Vindoline was efficiently extracted from the leaves of vinca (Cafharanthus roseus) by using supercritical carbon dioxide, whereas catharanthine was chemically extracted from the in vitro cultured hairy roots. The extracted crude monomeric precursors were purified by a two-step preparative TLC. The coupling reaction was carried out in the 0.1M glycine buffer(pH 2.0, 5ml) containing 40mM FeC13 with purified vindoline(0.3mg) and catharanthine(0.3mg) at 4°C. The production yields (weight %) of vinblastine and 3, 4-anhy-drovinblastine in the products were 23.2 and 26.0, respectively. The produced vinblastine was confirmed by FAB-MS.
