実験例1(DGAT1阻害活性)
(1)ヒトDGAT1遺伝子のクローニングと組換えバキュロウイルスの調製
ヒトDGAT1遺伝子は、ヒトcDNAライブラリを鋳型とし、DGAT1をコードする塩基配列(Genbank Accession No. NM_012079における245-1711)をPCR反応で増幅することにより取得した。
ヒトDGAT1酵素の調製は、前項で得られた組み換えバキュロウイルスを、expresSF+(R)昆虫細胞(日本農産工業(株))に感染させることにより行った。expresSF+(R)細胞へ組換えバキュロウイルスを添加して72時間培養した後、遠心分離によって細胞を回収し、-80℃で凍結保存した。凍結保存した細胞を氷中で融解し、Complete Protease Inhibitor(Roche)を添加した緩衝液 (200mM Sucrose、1mM EDTA、100mM Tris-HCl(pH7.4))に懸濁した後、超音波破砕を行った。その後、常法によりミクロゾーム画分を取得し、DGAT1高発現ミクロゾームとして-80℃で凍結保存した。
DGAT1の酵素反応に用いる緩衝液として、100mM Tris-HCl(pH7.4)、200mM Sucrose、20mM MgCl2、0.125% Bovin Serum Albumin (BSA)を使用した。この緩衝液に、所定濃度の試験化合物、および15μM ジオレイルグリセロール、5μM [14C]-パルミトイル-CoA、100μgタンパク/mL DGAT1高発現expresSF+(R)ミクロゾーム、0.75%アセトン、1%ジメチルスルホキシドを添加し、100μLの容量で、トリグリセライド(TG)合成反応を30℃で20分間行った。90μLの反応液を810μLのメタノールに添加し、反応を停止させた。反応液をOasis(R) μElutionプレート(ウォーターズ社製)に添加し、150μLのアセトニトリル:イソプロパノール(=2:3)の混合液で溶出した。溶出液にMicroScintiTM-40(パーキンエルマー社製)を150μL添加し、十分に攪拌した後、TopCountTM-NXT(パーキンエルマー社製)を用いて測定することにより、反応で生成した[14C]-TG量を定量した。
阻害率(%)=(1-(試験化合物添加時TG量-ブランクTG量)÷(対照TG量-ブランクTG量))×100
実験結果を下表34に示す。
<実験方法>
6~9週齢の雄性ICRマウスを一晩絶食後、試験化合物を0.2%カルボキシメチルセルロース溶液に懸濁させ、経口投与した。30分後に脂質(イントラリポス20%、大塚製薬、10mL/kg)を経口投与した。脂質投与直前、および2時間後に尾静脈より採血を行い、血漿を得た。血漿中TGの測定は、トリグリセリドEテストワコー(和光純薬)を用い、脂質投与による血漿中TG上昇値を算出した。溶媒対照群における血漿TG上昇値を対照とし、試験物質投与群における血漿TG上昇抑制率を算出した。
上記の結果、投与量5mg/kgにおいて、実施例の化合物は下表35に示す血漿TG上昇抑制率を示した。
<実験方法>
7~10週齢の雄性C57BL/6Jマウスを一晩絶食後、試験化合物を0.2%カルボキシメチルセルロース溶液に懸濁させ、経口投与した。直後に高脂肪食(オリエンタル酵母、60cal% fat)を与え、自由に摂取させた。4時間後までの摂食量を測定し、溶媒対照群における摂食量を対照としたときの試験物質投与群における摂餌量の低下率(摂食抑制率)を算出した。
投与量5mg/kgにおいて、実施例の化合物は下表36に示す摂食抑制率を示した。
<実験方法>
8週齢の雄性KK-Ayマウスに、高脂肪食(オリエンタル酵母、60cal% fat)を与え、試験化合物を0.2%カルボキシメチルセルロース溶液に懸濁させたものを、一日一回経口投与した。2週間の反復経口投与を行い、試験期間内の溶媒対照群の体重増加量を100%として、試験物質の体重増加抑制率を算出した。最終投与後、一晩絶食し、尾静脈より採血を行った。血糖値の測定はグルコースCIIテストワコー(和光純薬)、血漿中インスリンの測定はマウスインスリン測定キット(森永生化学研究所)を用いて行った。
上記の結果、投与量30mg/kg/日において、溶媒対照群と比較して、実施例の化合物は次表37に示す血糖降下作用及び血漿インスリン低下作用、体重増加抑制作用を示した。
