から選択される、[1]に記載の化合物、または医薬として許容なその塩。
式(I)の化合物の「医薬として許容な塩」とは、医薬品として使用可能な塩であれば特に限定されない。本発明化合物が塩基と形成する塩としては、ナトリウム、カリウム、マグネシウム、カルシウム、アルミニウムなどの無機塩基との塩;メチルアミン、エチルアミン、エタノールアミン等の有機塩基との塩などが挙げられる。当該塩は、酸付加塩であってもよく、かかる塩としては、具体的には、塩酸、臭化水素酸、ヨウ化水素酸、硫酸、硝酸、リン酸等の鉱酸;および、ギ酸、酢酸、プロピオン酸、シュウ酸、マロン酸、コハク酸、フマル酸、マレイン酸、乳酸、リンゴ酸、酒石酸、クエン酸、メタンスルホン酸、エタンスルホン酸などの有機酸酸との酸付加塩が挙げられる。
炭水化物応答領域結合タンパク質(Carbohydrate-responsive element-binding protein、略称: ChREBP)の発現に関するアッセイを行うために以下の細胞を作成した。
リバース:5’-ATGCATGCGGCCGCTTATAATGGTCTCCCCAGGGTGCC-3’。
SV40MES13-ChoRE-Luc_FLAG-ChREBP細胞をCorning384ウェル(コーニング社)のウェル当たり104細胞ずつプレーティングし、DMEM培地にて1日間培養した。翌日、培地を高グルコース(25mM)DMEM培地に置換した。これに、20μMとなるように化合物を1種類ずつ添加し、1日間培養した。その後、各ウェルごとにルシフェラーゼ活性を測定した。結果を図12に示す。高グルコース培地を用いて培養された細胞において試験化合物がChREBPの発現を抑制することが確認された。さらに各化合物について複数の濃度において試験した結果を図13に示す(濃度はμM)。
モデルマウスとしてiNOSトランスジェニックマウス(Takamura T. et al., J Biol Chem. 1998; 273: 2493-2496;岡本宏東北大学名誉教授より分譲)を用いた。前記Takamuraらの文献に従いiNOSトランスジェニックマウスと野生型(CD1(ICR))マウスの交配により、4週齢のモデルマウス(実験群n=8、対照群n=6)および前記モデルマウスと同時に生まれる非トランスジェニックマウスである野生型群(n=8)に高タンパク質・高カロリー食を与えた飼育を13週間行った。実験群にはさらに、化合物12(D-532)を6mg/kg/dayで経口投与した。各群について、体重を毎日測定し、3週間ごとに血糖値、尿中アルブミン及び尿中クレアチニンを常法に従って測定した。飼育終了後、各群をサクリファイスし、解剖時に腹部大静脈から採取した血液における血清クレアチニンの測定と解剖時に採取した腎臓における遺伝子発現解析を行った。腎組織についてはHE, PAS各染色を施し観察した。
試験例3で用いたマウスにおいて、腎臓におけるChREBPの標的遺伝子であるChREBPβ、TXNIP遺伝子を発現変動を定量PCRによって、既報(Genes to Cells 19 (2013) 52-65)の方法で分析した。ChREBPβの増幅には以下のプライマーセットを用いた。
リバース:5’-CTTGTCCCGGCATAGCAAC-3’。
リバース:5’-AGCTCATCTCAGAGCTCGTCCG-3’。
SV40MES13-ChoRE-Luc_FLAG-ChREBP細胞を用いて既報(Biochemical and Biophysical Research Communications 489 (2017) 21-28)に記載のルシフェラーゼ活性測定方法を用い、細胞生存性試験を行った。SV40MES13-ChoRE-Luc_FLAG-ChREBP細胞を低グルコース(5.5mM)DMEM培地で24時間培養後、各化合物を含む高グルコース(25mM)DMEM培地(実験群)、化合物を含まない低グルコースDMEM培地及び高グルコースDMEM培地(以上まとめて対照群)へと培地を交換し、交換後24時間培養した細胞由来のルシフェラーゼ活性を前記既報に従って測定した。結果を図14に示す。さらに各化合物について複数の濃度において試験した結果を図15に示す(濃度はμM)。
試験例3の投与群および非投与群のモデルマウスおよび野生型群のマウスの腎臓を2%PFA(Wako;163-20145)/2.5%グルタールアルデヒド(TAAB;G017/1)/0.1Mカコジル酸緩衝液(Wako;036-18175)を含む前固定液に入れ、室温で2時間処理した。前固定した腎臓は、0.1Mカコジル酸緩衝液(8%スクロース(Wako:196-00015)を含む)にて氷上で15分間×4回洗浄し、1%四酸化オスミウム(Wako;154-01014)を含む後固定液にて氷上で90分間処理した。後固定した腎臓は超純水にて15分間×3回洗浄を行い、50、60、70、80、90、95%エタノール水溶液に各10分間×1回、さらに100%エタノールに20分間×3回入れエタノール脱水を行った。脱水後は酸化プロピレン(Wako;165-05026)に10分間×2回反応後、酸化プロピレン/エポン樹脂(MNA(TAAB;M012):DDSA(TAAB;D027):Epon812(TAAB;T026):DMP-30(TAAB;D032)=20:10:30:1)の混合液(1:1)に室温で60分反応後、酸化プロピレン/エポン樹脂混合液(1:3)に室温で一晩反応させ、さらにエポン樹脂に30℃で一晩反応させて包埋後、60℃にて2日間重合反応させた。
モデルマウスとしてdb/dbマウス(ヘテロマウス(db/m+)の交配により入手)を用いた。16週齢のモデルマウス(実験群n=8、対照群n=6)およびヘテロマウス(db/m+)(有限会社熊谷重安商店より購入)である野生型群(n=8)を用い、試験例3と同じ条件で試験し、結果を解析及び観察した。結果を図17~図21に示す。試験例3に記載のモデルマウスを用いて観察された効果(図3~図6および図9)と同様の効果がdb/dbマウスを用いた場合においても確認された。
試験例7で用いたマウスにおいて、試験例4と同じ方法でChREBP標的遺伝子発現解析を行った。結果を図22および図23に示す。ChREBPβおよびTXNIPについて、D532投与による発現低下を認めた。
試験例7で用いたマウスにおいて、試験例6と同じ方法にて腎臓組織を観察した。結果を図24A~Cに示す。db/dbマウスにおいてもiNOSマウスにおいて観察された効果(上記図16)と同様の効果が確認された。
試験例7の実験群と対照群(db/dbマウスの非投与群)の血糖値と尿中アルブミン排泄量(ACR)について、統計解析ソフトのSPSSを用いて、横軸に血糖値、縦軸にACRとなるように散布図を作成し、回帰直線(最小二乗法による線形近似)を求めた。結果を図25に示す。対照群と実験群の回帰直線の傾きは大きく異なることから、D-532のACRに対する作用は血糖値低下作用に対して有意である、つまりD-532によるACR改善作用(腎保護作用)は血糖値低下作用に伴った間接的な変化ではなく、直接的に腎臓に作用していると考えられる。
