산화적인 스트레스(Oxidative stress)는 신경염증의 발병요인 중의 하나로 알려져 있다. 이에 본 연구는 약용곤충추출물을 이용하여 항산화 물질을 찾고자 초고속 적용가능한 스크리닝 방법을 적용하였다. 우선, 분자염증은 활성산소 관련의 물질과 밀접한 관련이 있으므로 이들의 억제를 동반하는 추출물을 먼저 선별하였다. 항산화 실험과 관련하여 DPPH (1,1-Diphenyl-2-picrylhydrazyl), FRAP(Ferric ion redu
Oxidant stress is well-known for a pivotal parameter related to neuro-inflammatory diseases including Alzheimer's disease, Parkinson's disease, and ALS (Lou Gehrig's disease). In order to effectively screen for anti-inflammatory agents, we first established the infrastructure of high throughput screening for anti-oxidant agents from medicinal insect library extracted with water, methanol, ethanol, and dimethyl sulfoxide. By the screening system, we found that Tenodera angustipennis Saussure, Pyrocoela rupa Olivier and Papilio maackii Mntris had strong anti-oxidant activity. Moreover, Tenodera angustipennis Saussure and Tenodera aridifolia (Stoll) exhibited protection effects of cellular damage by treatment of an oxidant hydrogen peroxide. Together, the results suggest that some selected hits could be a potential agent against neuro-inflammation, although the in vivo studies should be clearly tested.
