Abstract

Biological properties of DongChongXiaCao extracts and culture supernatants were evaluated using DPPH and FRAP (antioxidants), Raw 264.7 (NO production), B16-F1 cells (cell migration activity) and HUVECs (angiogenesis activity). We found that antioxidant activity was higher in mycelium culture supernatants than in mycelial extracts. Mycelial extracts and culture supernatants inhibited or increased cyclooxygenase-2 transcription activity and NO production. Various extracts and culture supernatants inhibited B16 cell migration and motility, and inhibited HUVEC tube formation. These findings indicate that DongChongXiaCao extracts and products of mycelium could be a useful biological resource for anti-oxidant and anti-cancer purposes.

동충하초 20여종의 균사와 배양 배지를 이용하여 생물학적 활성 효과를 항산화와 항암 실험을 통하여 알아보았다. 항산화 활성 실험 DPPH와 FRAP실험을 실시하였는데 다수의 동충하초 추출물에서 항산화 활성을 확인할 수 있었으며, 시간에 따른 FRAP활성에서는 배양배지에서 균사체 추출물보다 높은 활성을 나타내었다. NOS와 관련성을 확인하기 위하여 NO활성 실험을 한 결과 NO활성은 추출물의 종류에 따라 증가 또는 감소시키는 것을 알 수 있었다. 염증과의 관련성을 확인하기 위하여 Cox-2 promoter활성실험을 한 결과, 종에 따라 활성의 증가 또는 감소는 다양하게 나타났다. Wound healing assay를 이용하여 항암효과를 알아본 결과 많은 종에서 세포의 운동성을 억제하는 효과를 가지는 것으로 나타났다. 또한 혈관생성 억제효과를 알아보기 위하여 HUVECs를 이용하여 tube formation을 확인해 본 결과 다수의 추출물에서 혈관생성을 억제하는 것으로 나타났다.
