Abstract

In this study, the effects of low molecular weight chitooligosaccharides were assessed. Low molecular weight chitooligosaccharide evidenced no cytotoxicity in in vitro trials with the normal cell line, Vero E6(Africa green monkey kidney cell). The $IC_{50}$ of low molecular weight chitooligosaccharide was $923.20{\mu}g/m{\ell}$. Low molecular weight chitooligosaccharide exhibited in vitro antineoplastic activity in five human tumor(lung carcinoma, bladder carcinoma, colon carcinoma, stomach carcinoma, breast carcinoma) cell lines. The $IC_{50}$ values of low molecular weight chitooligosaccharide on A549, J82, SNU-C4, SNU-1 and ZR75-1 were $477.42{\mu}g/m{\ell}$, $480.40{\mu}g/m{\ell}$, $436.84{\mu}g/m{\ell}$, $373.55{\mu}g/m{\ell}$, and $539.95{\mu}g/m{\ell}$, respectively.

저분자량 키토산 올리고당의 세포 독성을 실험하였다. 저분자량 키토산 올리고당은 정상세포주인 Vero E6(Africa green monkey kidney cell)에 대한 세포 독성을 거의 나타내지 않았다. 정상세포주에 대한 저분자량 키토산 올리고당의 $IC_{50}$값은 $1,060.28{\mu}g/m{\ell}$이었다. 저분자량 키토산 올리고당은 폐암 세포주인 A549, 방광암 세포주인 J82, 대장암 세포주인 SNU-C4, 위암 세포주인 SNU-1, 유방암 세포주인 ZR75-1 등과 같은 사람의 종양세포주에 대한 in vitro 항종양성을 나타내었다. 종양세포주에 대한 저분자량 키토산 올리고당의 $IC_{50}$값은 A549, J82, SNU-C4, SNU-1, ZR75-1 세포주의 경우에 각각 $477.42{\mu}/m{\ell}$, $480.40{\mu}g/m{\ell}$, $436.84{\mu}g/m{\ell}$, $373.55{\mu}g/m{\ell}$, and $539.95{\mu}/m{\ell}$이었다.
