Abstract
In the preliminary study, we investigated the anti-complementary activities of 62 extracts from Korean edible seaweeds. Of those, Pachymeniopsis elliptica showed the highest anti-complementary activity. Therefore, it was purified as follows; i) PE-1 by ethanol precipitation, ii) PE-1-C by ultrafiltration, iii) PE-1-CIV by DEAE-Toyopearl 650C, and iv) PE-1-CIV-ii by Sepharose CL-6B. The purified compound, PE-1-CIV-ii, was the complexed homogeneous polysaccharide (molecular mass: 780 kDa) with 82.9% of anti-complementary activity. Also, it contained a significant amount of sulfate group (30.5%), which indicated it as a sulfated algal polysaccharide. Its structural monosaccharides were galactose (44.3%), 3,6-anhydrogalactose (34.0%), glucose (8.2%), fucose (5.4%), xylose (5.2%) and rhamnose (2.9%). After the treatment of periodate on a sample, a significant decrease in anti-complementary activity was found, which was a characteristic of bioactive polysaccharides. And-tumor activity of PE-1-A, B and C was tested in the sarcoma-180 solid tumor model. The PE-1-C with the largest molecular mass (more than 300 kDa) showed 81% of inhibition on the solid tumors, suggesting that the anti-complementary activity was, at least in part, related to anti-tumor activity. Based upon these results, the purified polysacchardes could be an immunopotentiator in vivo.
해조류 추출물을 대상으로 항보체 활성을 검색한 결과 우수한 활성을 나타낸 참도박을 열수 추출하여 활성물질을 정제하였다. 참도박 열수 추출물을 ethanol 침전을 통해 조다당류를 얻었다. 조다당류 PE-1을 한외여과를 실시하여 분자량에 따라서 100 kDa 이하의 PE-1-A, 100에서 300 kDa 이하의 PE-1-B, 300 kDa이상의 PE-1-C를 얻었으며 우수한 활성을 보인 PE-1-C(ITCH50(%): 71.5%)를 DEAE-Toyopearl 650C ion exchange column에서 분리하여 0.75M NaCl(PE-1-CIV) 용출 획분을 이용하여 size exclusion chromatography를 실시하였다. Sepharose CL-6B 통해서 분리된 PE-1-CIV-ii (
