고란초 생물 전환 추출물의 항염증 효과

Biorenovation은 미생물의 효소적 기능을 이용하여 천연 추출물과 같은 소재를 생물전환하는 기법으로 생리활성이 증진되거나 세포독성을 감소시키는 효능이 보고되었다. 이에 본 연구는 천연 소재의 생리활성을 증진하고 가치를 향상시키고자 biorenovation 기법을 적용하여 고란초 전엽체 추출물(CH)을 생물전환하였고, LPS로 자극된 RAW 264.7 세포를 사용하여 항 염증 활성을 평가하였다. 세포 사멸을 보이지 않는 50-200 μg/mL 농도에서 CH와 생물 전환 추출물(CHB)의 Inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2)의 발현량 및 전 염증성 사이 토카인의 생성량을 조사한 결과, CHB는 CH보다 산화질소, prostaglandin E 2 및 사이토카인(interleukin-6, interleukin-1β, tumor necrosis factor-α)의 생성을 억제하였으며, 특히 CHB는 200 μg/mL 농도에서 LPS 자극에 의한 iNOS 및 COX-2 단백질의 발현을 무 처리군과 유사한 수준으로 억제하였다. 이러한 결과는 biorenovation 생물 전환을 통해서 기존 식물 추출물의 항 염증 활성이 증진될 가능성을 나타내며, CHB가 효과적인 항 염증 소재로서 화장품 및 건강기능식품에 적용될 가능성을 시사한다. Biorenovation is a method for converting materials using the enzyme properties of microorganisms. Natural products converted by that method increase physiological activity or reduce cytotoxicity. In this study, we investigated the anti-inflammatory activity of crypsinus hastatus prothallium (CH) and biorenovated CH prothallium (CHB) using RAW 264.7 cells stimulated with lipopolysaccharide (LPS). CHB inhibited the production of nitric oxide, prostaglandin E 2 and cytokines (interleukin-6, interleukin-1β, tumor necrosis factor-α) compared to CH at a concentration of 50-200 μg/mL. In addition, CHB concentration of 200 μg/mL inhibited the expression of inducible nitric oxide synthase and cyclooxygenase-2 protein by LPS stimulation to the level of the untreated control group. These results indicate that CHB could be a novel anti-inflammatory agent for cosmetic and pharmaceutical ingredients.It also suggests that the application of biorenovation has potential usefulness in developing anti-inflammatory materials. It also suggests that the application of bio-renovation has potential usefulness in the development of inflammatory material. We applied Biorenovation technology to Distylium racemosum extract (DR) to generate Distylium racemosum biorenovation product (DRB), and investigated the anti-inflammatory properties of DRB in lipopolysaccharide (LPS)-treated RAW264.7 macrophages.
