  • This study was performed to investigate the effects of acteoside and isoacteoside isolated from Clerodendron trichotomum Thunberg on melanin production in B16 melanoma cells. In DPPH radical scavenging activity, acteoside and isoacteoside had a potent anti-oxidant activity in a dose-dependent manner. Both acteoside and isoacteoside dose-dependently inhibited silica-induced ROS (reactive oxygen species) generation in B16 melanoma cells. They significantly inhibited tyrosinase activity and melanin production in MSH-stimulated B16 melanoma cells. The inhibitory effect of acteoside was more potent than that of isoacteosidee. In Western blot of tyrosinase, acteoside inhibited MSH-induced tyrosinase expression in B16 melanoma cells, which is related to the inhibitory action of acteoside on tyrosinase activity and melanin production. These results show that acteoside and isoacteoside from Clerodendron trichotomum Thunberg has a potent antioxidant activity and whitening activity. The underlying mechanism of acteoside on whitening activity may be due to the inhibition of tyrosinase activity and tyrosinase expression.

  • 최근에 한국 고유종인 미선나무 (Abeliophyllum distichum Nakai; Oleaceae) 품종 옥황1호의 유전체가 성공적으로 해독되었다. Acteoside는 다양한 활성을 가지는 물질이며, 여러개의 생화학합성과정이 제시되어왔고, 이들을 통합 검토하여 정확한 생화학합성과정을 완성하였다. 유전체 데이터로부터 2차대사산물을 예측할 수 있는 MetaPre-AITM와 정확한 acteoside 생화학합성과정, InfoBoss Pathway Database를 활용하여, acteoside에 관여하는 모든 효소의 유전자를 옥황1호 유전체로부터 성공적으로 확인하였다. 이는 옥황1호는 acteoside 물질을 생산할 수 있는 가능성이 있음을 의미한다. 이에 고성능액체크로마토그래피를 사용하여 옥황1호의 캘러스 세포를 분석하여 acteoside과 이의 유도체인 isoacteoside를 확인하였다. 본 연구는 MetaPre-AITM은 유전체로부터 2차대사산물을 성공적으로 예측하였다. 이 방법은 화학물질보다 안정적인 DNA를 분석하여 2차 대사산물을 예측하는 효율적인 방법이 될 것이다.

  • Acteoside는 일명 Verbascoside로 불리우는 Phenylpropanoid glycoside에 속하는 화합물로 이미 보고되어진 생리활성으로는 Cytotoxic effect, Anti bacterial effect, Immunosuppressive effect, C-AMP Phospaestrase의 저해활성등 여러가지 생리활성이 보고되어 있다. 저자등은 마주송이풀의 성분을 규명하는 가운데 acteoside가 주성분임을 확인하게 되었고 이 식물이 한의서에서 관절염등에 사용되어 진다는 점에서 소염활성을, 식물을 건조할때 흑색으로 변하는데 착안하여 iridoid glycoside의 존재가 추정되어 iridoid glycoside의 일반 생리활성인 담즙분비 촉진작용과 간장보호 작용을 검색하던 중 phenylpropanoid glycoside인 acteoside에서도 담즙분비촉진 작용과 간장보호작용의 지견을 얻었기에 보고하고자 한다.

  • The effect of acteoside, a phenylpropanoid glycoside isolated from Clerodendron trichotomum Thunberg, on histamine and arachidonic acid release was investigated in RBL 2H3 cells. Histamine was dose-dependently released from RBL 2H3 cells by melittin, arachidonic acid and thapsigargin. In extracellular $Ca^{2+}-free$ solution, basal secretion of histamins increased by two fold. The response of histamine release to melittin and thapsigargin in $Ca^{2+}-free$ solution was significantly decreased, whereas the response to arachidonic acid was significantly increased as compared with those in normal solution. Acteoside inhibited histamine release induced by melittin, arachidonic acid and thapsigargin in a dose-dependent manner in the presence or absence of extracellular $Ca^{2+}$. However, the inhibitory activity of acteoside was more potent in normal solution than that in $Ca^{2+}-free$ solution. These data suggest that inhibitory mechanism of acteoside on histamine release may be related to extracellular $Ca^{2+}$. On the other hand, acteoside significantly inhibited arachidonic acid release and prostaglandin $E_2$ production Induced by $0.5\;{\mu}M$ melittin. It is possible that acteoside may be developed as an anti-inflammatory agent.

  • In previous reports, we exhibited that acteoside showed significant cytotoxicity against various cancer cells. In this study we investigated that acteoside is capable of inducing differentiation in HL -60 human leukemia cell line. After being treated with acteoside, the growth curve was decreased remakably in a dose- and time-dependent manner, and cell doubling time was delayed. Exposure of cells to 20 $\mu\textrm{g}$/m$\ell$ acteoside induced differentiation of HL-60 cells to monocyte/macrophage-like cells by cell surface antigen expression. The percentage of NBT reducing activity was increased in a time-dependent manner. In addition. the protein lever of p21 and p16 increased and ppRb decreased in western biot analysis. Theas results suggest that acleoside possess the activity of inducing differentiation in HL-60 cells.

  • The protective effects of acteoside, a phenylethanoid glycoside, on cabon tetrachloride-induced hepatotoxicity and the possible mechanisms involved in this protection were investigated in mice. Pretreatment with acteoside prior to the administration of carbon tetrachloride significantly prevented the increased serum enzymatic activities of alanine and aspartate aminotransferase in a dose-dependent manner.

  • 이온쌍 액체크로마토그래피(IP-HPLC)에 의해 마주송이풀 중 acteoside를 분리 정량하였다. 시료를 메탄올 40mL로서 4시간 추출하였다. 추출물에 대한 분리, 정제를 Sep-Pak $C_{18}$ catridge와 메탄올-물(메탄을 50%, 물 50%, 인산 완충용액 pH=8.0)을 사용하였다. HPLC 분리조건은 poly(styrene-divinylbezene) PRP-1 역상컬럼($15cm{\times}4.6mm$ i. d., $5.0{\mu}m$)과 이동상으로 $5.0{\times}10^{-3}M$ tetrabutylammonium bromide가 포함된 메탄올-물(메탄을 60%, 물 40%, 인산 완충용액 pH=8.2)을 사용하였다. 이와 같은 조건으로 강원도 평창군 일대에서 채집한 마주송이풀 중에 함유된 acteoside를 분리 정량한 결과 그 함량 범위가 0.062~0.076%였다.

  • We investigated the in vitro effect of Acteoside , phenylpropanoid glycosides. is a natural product isolated from …. on proliferation, differentiation and cell cycle regulation in human promyelocytic HL -60 leukemia cells. Acteoside significantly inhibited the proliferation of HL -60 cells, with IC50 of about 30$\mu\textrm{g}$/$m\ell$. It was also found to be a potent inducer of differentiation in human leukemia derived HL-60 cells through the examination of differentiation markers. (omitted)

  • 건조 방식에 따른 미선나무 잎의 항산화 활성 및 항염증 효과를 확인한 결과, 높은 항산화 활성를 나타냈으며, 건조 잎에 비해 생잎의 항산화 활성이 뛰어났다. 페놀류 화합물의 함량은 유의적인 차이가 없었으나, 미선나무의 활성물질로 알려진 acteoside의 함량을 분석한 결과, 생잎의 acteoside의 함량이 높았다. 또한 항염증 효과를 확인하기 위해 nitric oxide의 함량 및 세포 수준에서의 염증 관련 인자인 iNOS와 COX-2의 단백질 발현 및 mRNA 수준을 확인한 결과, 생잎의 억제활성이 건조잎보다 높았다. 이를 통해 건조 잎에 비해 생잎의 이용가치가 높았으며, 이러한 항산화 및 항염증 활성은 acteoside의 함량의 차이와 밀접한 관련이 있는 것으로 사료된다.
