Description
(試験サンプルの調製)
市販のキサントフモール(Steiner社、XN Extract(75%))をHPLCで精製し、キサントフモール標準品を調製した。これを5%ジメチルスルホキシド(DMSO)水溶液に段階希釈して、所定濃度の試験サンプルを得た。HPLCは下記条件で行った。
HPLC条件:
カラム:CAPCELL PAK C18(φ1cm)(資生堂)
移動相:77.5%CH3OH/5%CH3COOH
流速:3mL/分
キサントフモールのCETP阻害活性を、CETP Inhibitor Drug Screening Kit(Bio Vision社)を用いて測定した。具体的には、下記組成の反応液を384ウェルプレートに20μL/ウェル分注して、37℃で450秒間インキュベートし、その後、プレートリーダーで蛍光強度を測定した。測定された蛍光強度は、別途作成した検量線に基づいて中性脂質量に変換した。
反応液組成:
試験サンプル:80μL
ウサギ血清:3μL
供与分子溶液:5μL
受容分子溶液:5μL
10×CETPバッファー:10μL
反応液中の全中性脂質量([S](pmol))と転送された中性脂質量(V(pmol))との関係は、表1及び図1に示す通りであった。また、[S](pmol)と[S]/Vとの関係は、図2に示す通りであった。表1及び図1、2において、“XN”はキサントフモールを表し、キサントフモール濃度(ppm)は反応液中の濃度である。
XN 0ppm: y=0.1534x+11.641
XN10ppm: y=0.1317x+19.679
XN20ppm: y=0.1773x+21.368
XN40ppm: y=0.1907x+35.422
(試験動物の群分け)
ハムスター(5週齢、雄、SPFシリアンハムスター、日本SLC)12匹を、試験開始時の体重が群間でバラつかないように各群6匹の2群(対照群(CNT群)、キサントフモール投与群(XN群))に分けた。なお、ハムスターは、1週間の馴化飼育を経た後、6週齢の時点で試験に使用した。
1週間の馴化飼育後、各群のハムスターに試験飼料及び水道水を28日間自由に摂餌・摂水させた。馴化飼育期間及びその後の試験飼料投与期間を通じて、ハムスターは、飼育装置(温度23±5℃、相対湿度55±10%、イノケージ、オリエンタル技研)中で個別飼育(1匹/ケージ)した。
キサントフモール(85%純度キサントフモールパウダー、ホップシュタイナー社)を投与量が5mg/kg−体重/dayとなるように、2%(v/v)Tween20を含有するDMSOに溶解させ、浸透圧ポンプ(ALZET(登録商標) model 2006)に充填し、試験開始前に外科手術によりハムスター背面皮下に埋没させた。
試験開始時及び試験飼料投与開始から14日後、各群のハムスターについて、ヘパリン処理した毛細管を用いて眼窩から採血した。また、試験飼料投与開始から28日後、各群のハムスターについて、ジエチルエーテル麻酔下で心採血した。採血した血液は、遠心分離(5,000×g、5分間、室温)して血球と分離した後、コレステロールの測定に供した。総コレステロール値、HDLコレステロール値は、コレステロールE−テストワコー(和光純薬工業株式会社、Code439−17501)、HDL−コレステロールE−テストワコー(和光純薬工業株式会社、Code431−52501)を用いて測定した。なお、HDLコレステロール値測定時のHDL以外のリポ蛋白の沈殿操作は、キット添付の沈殿試薬を用いず、ポリエチレングリコール沈殿法により行った。また、非HDLコレステロール中の成分の分析は、スカイライトバイオテック社に委託した。
各測定項目について、統計解析ソフトSPSS(ver.13.0J)を用いてスチューデントのt−検定を行った。
結果(平均±標準偏差)を表3〜5に示す。表3及び表4は、試験飼料投与開始から14日後及び28日後における血漿中コレステロール(総コレステロール、HDLコレステロール、非HDLコレステロール)の値を示すものである。表3及び表4中の数値は、試験開始時における各血漿中コレステロールの値を1としたときの相対値を示す。表5は、試験飼料投与開始から28日後における血漿中非HDLコレステロールに含まれるCM(カイロミクロン)、VLDL(超低密度リポタンパク質)、LDLの含有量を示す。表5中の値の単位は、mg/dlである。
(試験動物の群分け)
ハムスター40匹を、対照群(CNT群)、1mg/kg−体重/dayキサントフモール投与群(XN 1mg群)、5mg/kg−体重/dayキサントフモール投与群(XN 5mg群)、及びネガティブコントロール群(NC群)の4群に各群10匹づつ分けた以外は実施例2と同様にして行った。
実施例2と同様に調製した。なお、ネガティブコントロール群(NC群)には、馴化飼育期間及び試験期間を通して、飼料としてCRF−1を使用した。
飼育期間を14日間とした以外は、実施例2と同様にして行った。
XN 1mg群について、キサントフモールが1mg/kg−体重/dayとなるようにした他は、実施例2と同様にして行った。
試験飼料投与開始から14日後、糞中総コレステロール量を測定した。凍結乾燥した糞を粉砕し、秤量した後、飽和水酸化カリウム水溶液でアルカリ処理し、エタノールを添加した後、更にヘキサンを加え、総コレステロールをヘキサン層に分配した。ヘキサン層の容量を定量した後、コール酸に抱合させたうえで乾固し、コレステロールE−テストワコーで糞中総コレステロール量を測定した。
試験飼料投与開始から14日後、糞中胆汁酸量を測定した。凍結乾燥した糞を粉砕し、秤量した後、90%エタノール中65℃でインキュベートした。これを遠心分離した後、上清を新しい容器に回収した。この操作を3回繰り返し行って胆汁酸を抽出した。得られた上清を乾固し、総胆汁酸−テストワコー(和光純薬工業、Code431−15001)で測定した。
