Inhibitory effects of RMC proliferation were showed that Dalbergia odorifera T. Chen., Melia azedarach Linné and Hydnocarpus anthelmintica Pierre. Among them Hydnocarpus anthelmintica Pierre had the highest anti-oxidative activity (ORAC PE value = 1.6, DPPH = 81.1), but Dalbergia odorifera T. Chen. and Melia azedarach Linné had no effects. These results suggest that the Hydnocarpus anthelmintica Pierre could prevent or protect from kidney disease as antioxidant and anti-proliferative agent for RMC.

ROS 가과도하게생성되면체내세포와조직에산화적세포손상을일으켜노화를촉진시키고암, 동맥경화, 파킨슨병, 알츠하이머병, 2형당뇨병등의각종질병을유발한다고알려져있다 (Arai et al., 2007; Farooqui and Farooqui., 2011; Garcia-Bailo et al., 2011; Hong et al., 2011; Jomova et al., 2010; Kim et al., 2010; Matés, 2000; Park et al., 2007). 또한, 신장에서산화적스트레스로인해생성되는 ROS는만성신부전과같은신장질환및신장질환에서의합병증을야기시키고, 항암제로사용되는 cisplatin 에의한신장독성에도관련이 * 교신저자 (E-mail) : sckang73@gachon.ac.kr; hanhs@joongbu.ac.kr 있다고보고된바있다 (Feng et al., 2013; Hong et al., 2011; Modlinger et al., 2004; Rodrigo and Rivera, 2002; Sung et al., 2008). 한편, ROS 에대한방어기구로서사용되는항산화제는생체이물, 약물, 발암물질, 유해한라디칼반응의부작용에대해직접또는간접적으로세포를보호하는물질로서약용식물에포함된여러성분들은높은항산화활성을나타내며, 많은항산화제들이자유라디칼과 superoxide 를제거하거나해독및방어하는단백질을활성화시키는능력을지니고있다고알려져있다 (Halliwell, 1995; Kocic et al., 2002; Shin et al., 2012). 사구체혈관간세포 (rat mesangial cells) 의증식은신부전의특징중하나로서, 혈관간세포의증식과이에따른세포외기질의과도한축적은사구체간질의확장을야기시켜신부전증에서나타나는사구체경화에큰영향을미치는것으로알려져있다 (Catherwood et al., 2002). 활성산소에의한신부전증유발및사구체혈관간세포의증 c 본학회지의저작권은 ( 사 ) 한국자원식물학회지에 -652- 있으며, 이의무단전재나복제를금합니다.
한약재추출물의항산화및사구체혈관간세포증식억제활성탐색 식은급 만성신부전증을초래한다. 따라서, 본연구에서는 63 종의한약재추출물에서항산화활성및사구체혈관간세포의증식억제능을탐색함으로써신장질환의예방및치료제로서개발가능한한약재를선별하고자하였다. 재료및방법재료본실험에서는경동시장 ( 서울, 한국 ) 에서 63종의한약재를구입하였으며, 증거표본및추출물을가천대학교생명과학과천연물신약연구실에보관하였다 (voucher specimen No. GNMR1 ~ GNMR63). 추출및분획 63종의한약재를세절하고음건한후 80% EtOH 을이용하여추출교반기로 24시간동안추출및여과하였다. 모든시료추출물은감압농축하고동결건조하여 -80 에보관하였다. 이중대풍자 1.8 kg 에서얻은 MeOH 추출물 598 g을증류수 1 L에현탁하고 n-hexane(1 L 3), CH 2 Cl 2 (1 L 3), EtOAc(1 L 3) 및 n-buoh(1 L 3) 순으로 1 : 1 비율로용매분획하여각각 143.6 g, 9.0 g, 13.1 g, 17.2 g과 208 g의 n-hexane, CH 2 Cl 2, EtOAc, n-buoh 및 H2O 분획물을얻었다 (Fig. 1). 세포배양 Rat mesangial cells(rmc) 는 American Type Culture Collection(ATCC, USA) 로부터분양받았으며, 10% fetal bovine serume(fbs, Invitrogen), 100 U/ ml penicillin, 100 μg / ml streptomycin 이포함된 Dulbeccos Modified Eagles Medium(DMEM, Invitrogen) 을사용하였다. 세포는 37, 5% CO 2 에서배양하였으며, 세포의과밀도현상을해소하기위하여계대배양하였다. RMC proliferation assay 세포에 63종의추출물 (50 μg /ml) 을 24시간처리한후배지를제거하고 200 μl의 MTT(0.5 mg/ml in media) 시약을각 well 에첨가하여 37 에서 3시간배양하였다. 상층액을제거하고 100 μl의 dimethyl sulfoxide(dmso) 를각 well 에첨가하여비수용성의보라색 formazan 을용해시켜 540 nm 에서흡광도를측정하였다. ORAC(oxygen radical absorbance capacity) assay 각시료를 DMSO 에희석하여 96-well 에넣은후양성대조군으로 trolox(fluka) 를시료의농도와동일하게넣어주었다. 이후 75 mm PE buffer 와 β-phycoerythrin(sigma) 을섞어서넣어준후, AAPH(Sigma) 를첨가하여 fluorometer(victor 3, Perkin Elmer) 를이용하여형광의변화과정을 excitation 535 nm, emission 590 nm에서 60분동안 2분간격으로측정하였다. AUC 및 Value PE 의산출방법은다음과같다. AUC(Area under he curve) = 1 + f1/f0 + f2/f0 + f2/f0 + + f19/f0 + f20/f0 <Relative ORAC value> = [(AUC sample - AUC black )/(AUC Trolox - AUC blank )] (molarity of Trolox/molarity of sample) DPPH(1,1-diphenyl-2-picryl hydrazil) assay ORAC법과비교하기위하여각시료의항산화활성은 DPPH free radical 소거법에의한전자공여능 (EDA) 방법으로측정하였다. 시료 0.5 ml 에 DPPH(1,1-diphenyl-2-picryl hydrazil) 를 3 ml 를가하고, 실온에서 30분간반응시킨후 UV-visible spectrophotometer(phanrmaca Biotech Ultraspec 3000, England) 를이용하여 517 nm 에서측정하였다. 결과및고찰본연구에서는경동시장에서구입한 63종의한약재를세절하고음건하여 80% EtOH 에서 24시간동안추출및여과하고감압농축한뒤동결건조하여 -80 에서보관하면서실험에사용하기전에실온에서조제하여항산화활성및생쥐의사구체혈관간세포주인 RMC 세포의증식억제능을확인하였다. 그결과, 강진향, 고련피, 대풍자, 목향이 50 μg /ml 의농도에서 RMC 세포의증식을 50% 이상억제하는것으로나타났으며, ORAC 와 DPPH assay를통한항산화활성을확인한결과, 백단향, 백렴은양성대조군 trolox(vitamin E, ORAC value = 1) 보다 2배이상증가하여가장우수한 ORAC 활성효능을보였고, 계혈등, 귀전우, 반대해는 1.5배이상의 ORAC 활성효능을보였으나, 반대로갈화, 감국, 감송, 건율, 고련피, 곡기생, 곤포, 구자, 구절초, 귀판, 백반은양성대조군인 trolox(vitamin E, ORAC value =1) 보다못미치는 ORAC 활성을나타냈다. 이중계혈등, -653-
