21 종의 생약 추출물을 선정하여 5 μg/ml의 농도에서 SK-MEL-28 cell 에 대한 세포독성을 조사한 결과 목단피의 메탄올 추출물이 74.3%의 성장율을 보였다. 활성 물질을 찾기 위하여 목단피로부터 silica gel column chromatography를 실시하여 hexane 분획과 EtOAc 분획에서 충 5개의 화합물을 분리하였고 mp, UV, IR, 1H-NMR, 13C-NMR 등 각종 물리, 화학적 data로부터 그 구조를 paeonol (1), benzoylpaeoniflorin (2), benzoic acid (3), 2,5-dihydroxy-4-methoxy-acetophenone (4), paeoniflorin (5)으로 동정하였다. 분리한 물질을 human 피부 암세포인 SK-MEL-28 세포주에 대하여 10 μg/ml의 농도에서 SRB방법으로 세포독성을 측정한 결과 compound 4가 ED50 값이 5.92 μg/ml로 가장 좋은 세포독성을 나타내었다. 이결과는 compound 4가 SK-MEL-28 melanoma 세포주에 대한 새로운 항암 후보 물질임을 제시한다.
The MeOH extracts from 21 species were tested for their cytotoxicity against SK-MEL-28 melanoma cell line and HaCat normal cell line in 5 g/ml by sulforrhodamine-B (SRB) method. Among them, the MeOH extract from Moutan Cortex Radicis showed the moderate activity with the growth rate of 74.3% in SK-MEL-28 cells and the high activity with the growth rate of 207.8% in HaCat cells. Activity-guided fractionation was performed and five compounds, paeonol (1), benzoylpaeoniflorin (2), benzoic acid (3), 2,5-dihydroxy-4-methoxy- acetophenone (4), paeonfliorin (5) were isolated from hexane and EtOAc fraction. The structures were established by physicochemical and spectrometric methods (mp, UV, IR, 1H-NMR, 13C-NMR, spectram). All compounds were evaluated for their cytotoxicity, compound 4 showed the significant cytotoxic activity with ED50 value of 5.92 μg/ml, but the other compounds no activity. These results suggest that compound 4 is a novel anticancer candidate against SK-MEL-28 melanoma cells.
