1H-NMR (CDCl3, 400 MHz) δ8.12 (d, 1 H, J = 2.4 Hz), 7.99 (dd, 1 H, J = 1.6, 8.0 Hz), 7.75 (bd, 1 H, J = 8.0 Hz), 7.66 (dd, 1 H, J = 2.0, 8.0 Hz), 7.63 (t, 1 H, J = 8.0 Hz), 7.14 (d, 1 H, J = 8.8 Hz), 3.55 - 3.48 (m, 4 H), 3.42 - 3.32 (m, 4 H), LC-MS: r.t. 3.06 min., m/z 425.9 (M+1)
(試験方法)
8週齢のS.D.ラット(雄、8匹)を麻酔下においてpuromycin aminonucleoside (PAN)を120 mg/kgで腹腔内へ注入した(day 0)。PANは糸球体基底膜細胞(podocyte)に障害を与え、糸球体障害ラットを誘導する。PAN処置ラットは、巣状分節性糸球体硬化症モデルラット及び微小変化型ネフローゼ症候群モデルラットである。PAN注入後3日目以降に、試験化合物(化合物011)を餌に混ぜて投与した(10mg/kg/day)。ラットの飼育は12時間明暗サイクル(7時-19時の時間帯は点灯、19時-翌朝7時の時間帯は消灯)条件下、餌及び水分は自由摂取とした(PAN+011群)。尿はPAN投与日である0日目、PAN投与後3、10、20及び27日目に回収した。尿の回収は、ラットを代謝ケージに17時間(17時-翌朝10時まで)入れることにより行った。
別途、対照として、PAN処置及び試験化合物投与をいずれもしない群(コントロール群、雄、3匹)、PAN処置をせず、試験化合物投与をした群(コントロール+011群、雄、5匹)、PAN処置をし、試験化合物を投与しない群(PAN群、雄、9匹)も同様に試験した。
尿蛋白量を、Bradford法を使用して測定した。
血清アルブミン量を、BCP(ブロモクレゾールパープル)改良法を使用して測定した。なお、PAN群では、血清サンプルの取得がうまくいかなかった1匹分を除いたため、血清サンプル数は8である。
PAN投与後27日目に、ラットの左腎臓を摘出して、その大きさを目視で確認し、その重量を測定した。コントロール群3匹すべての左腎臓を摘出してその重量を測定したため、左腎臓サンプル数は3である。コントロール+011群5匹のうち4匹の左腎臓を摘出してその重量を測定したため、左腎臓サンプル数は4である。PAN群9匹のうち7匹の左腎臓を摘出してその重量を測定したため、左腎臓サンプル数は7である。PAN+011群8匹のうち7匹の左腎臓を摘出してその重量を測定したため、左腎臓サンプル数は7である。
尿蛋白量測定結果を図1に示し、血清アルブミン量(27日目)測定結果を図2、左腎臓重量測定結果を図3に示した。
(試験方法)
2型糖尿病モデルマウスであるdb/dbマウスは、過食による著明な肥満と高血糖を呈し、糸球体肥大および糸球体障害から徐々に高度の尿蛋白を呈するようになる。すなわち糖尿病性腎症モデルマウスといえる。9週齢のdb/dbマウスに対して、試験化合物(化合物011)を餌に混ぜて8週間投与し(10mg/kg/day;糖尿病性腎症+011群)、試験化合物を投与しない他は同様にしたdb/dbマウス(糖尿病性腎症群)と比較することにより、糖尿病性腎症モデルに対する試験化合物の尿蛋白抑制効果を検討する。db/dbマウスを9週齢のdb/+マウス(非糖尿病マウス)に代えた他は同様にした群(コントロール群とコントロール+011群)も準備し、試験化合物を投与する群と投与しない群を設定する。以上の4群は、いずれも雄マウスを使用し、6匹/群とする。マウスの飼育は12時間明暗サイクル(7時-19時の時間帯は点灯、19時-翌朝7時の時間帯は消灯)条件下、餌及び水分は自由摂取とする。試験開始時(9週齢)、4週後(13週齢)、8週後(17週齢)において採尿を行い、Bradford法で尿蛋白量を測定する。
試験例1よりも長期重症化したPAN処置ラットに対する化合物011の作用を検討した。
(試験方法)
8週齢のS.D.ラット(雄、8匹)を麻酔下においてpuromycin aminonucleoside (PAN)を120 mg/kgで腹腔内へ注入した。その後、1か月後に再びPANを60 mg/kgで腹腔内に注入した。PANは糸球体基底膜細胞(podocyte)に障害を与えることで、巣状分節性糸球体硬化症モデルラットを作製する(Kim, J Mol Med,2018, 96,631-644)。更にこのモデルラットでは、リンパ球やマクロファージの浸潤を伴った慢性的な腎臓損傷が発生することが知られている(Ornellas, Sci Rep,2019,9:19604)。PAN注入後3日目以降に、試験化合物(化合物011)を餌に混ぜて投与した(10 mg/kg/day)。ラットの飼育は12時間明暗サイクル(7時-19時の時間帯は点灯、19時-翌朝7時の時間帯は消灯)条件下、餌及び水分は自由摂取とした(PAN+011群)。2回目のPAN投与しなくても1回目のPAN投与で慢性的に蛋白尿が生じることがある。このため、1回目のPAN投与を受けたラットの蛋白尿が十分に高値の場合は、そのラットについて2回目のPAN投与をしなかった。2回目のPAN投与されなかったラットも統計に含めた。
PAN1回目の投与の2カ月後に、ラットの腎臓を摘出して、その大きさを目視で確認し、その重量を測定した。腎臓サンプル数はPAN群について4、PAN+011群について6であった。その後、腎臓を4%パラホルムアルデヒド/PBSにて固定後、パラフィン包埋し、切片を作製した。切片をPAS(Periodic acid-Schiff stain)染色処理し、PAS染色陽性エリア(炎症細胞エリア)の評価を行った。
RNAを抽出するため、腎臓の表層付近の組織の一部を-80℃に急速凍結した。組織から抽出したRNAから逆転写酵素によりcDNAを作製し、リアルタイムPCR法にて遺伝子発現を評価した。反応に要した試薬にはTB Green Premix Ex Taq II(タカラバイオ)を用い、分析にはQuantStudio5 (Thermo fisher)を用いた。
左腎臓及び右腎臓重量測定結果を図4、PAS染色の解析結果を図5に示した。腎臓から取り出した発現遺伝子の定量的PCRの結果を図6に示した。浸潤した炎症性細胞の集団を図7に示した。
