メチレン基の2位への導入、18位に通常見出されるメチルから水素の置換、及び1α−ヒドロキシ−19−ノルビタミンD3の側鎖中の炭素23、24、25、26及び27の脱離は、1α,25−ジヒドロキシビタミンD3と比較すると、完全長組換えラットビタミンD受容体への結合にほとんど又は全く影響しなかった。化合物18,19−ジノル−2MPは、標準の1,25−(OH)2D3と比較すると、受容体にも5分の1結合した(図1)。これら結果から、化合物18,19−ジノル−2MPは、同様の生物学的活性を有するであろうと考えられる。しかしながら、驚くべきことに、化合物18,19−ジノル−2MPは、独特の生物学的活性を有する極めて選択的な類似体である。
ビタミンD受容体結合
試験材料
タンパク質源
完全長組換えラット受容体は、大腸菌(BL21(DE3)Codon Plus RIL細胞で発現させて二つの異なったカラムクロマトグラフィーシステムを用いて精製して均一にした。最初の系は本タンパク質上のC末端ヒスチジン標識を利用するニッケル親和性樹脂であった。本樹脂から溶離したタンパク質を、イオン交換クロマトグラフィー(S−Sepharose Fast Flow)を用いてさらに精製した。精製したタンパク質のアリコートを、液体窒素で急速冷凍して−80℃で使用まで貯蔵した。結合アッセイで用いるために、本タンパク質を、0.1% Chaps 洗浄剤を含むTEDK50(50mM Tris,1.5mM EDTA,pH7.4,5mM DTT,150mM KCl)中で希釈した。受容体タンパク質及びリガンド濃度を最適化して、加えた受容体に結合する放射性標識リガンドが20%以下になるようにした。
未標識リガンドを、エタノールに溶解させて、UV分光測光を用いて濃度を決定した(1,25(OH)2D3:モル吸光係数=18,200及びλmax=265nm;類似体:モル吸光係数=42,000及びλmax=252nm)。放射性標識リガンド(3H−1,25(OH)2D3,約159Ci/mmole)を、エタノール中で最終濃度1nMとなるように加えた。
放射性標識リガンド及び未標識リガンドを、最終エタノール濃度10%未満で希釈した100mclのタンパク質に加えて混合し、氷上で一晩インキュベートして結合平衡にした。翌日、100mclのヒドロキシルアパタイトスラリー(50%)を、各試験管に加え、10分間隔で30分間混合した。ヒドロキシルアパタイトを、遠心分離で回収後、0.5% Titron X−100含有Tris−EDTA緩衝液(50mM Tris,1.5mM EDTA,pH7.4)で3回洗浄した。最後の洗浄後、ペレットを4mlの Biosafe IIシンチレーション混合物入りシンチレーションバイアルに移して混合し、シンチレーション計数計に入れた。放射性標識リガンドのみが入っている試験管から全結合を決定した。
試験材料
研究用試薬
研究用試薬を、エタノールに溶解し、UV分光測光を用いて濃度を決定した。連続希釈液を作製して、一定範囲の試薬濃度を、細胞培養物中に存在するエタノールの最終濃度(0.2%未満)を変更せずに試験できるようにした。
ヒト前骨髄球性白血病(HL60)細胞を、10%ウシ胎児血清含有RPMI−1640培地で増殖した。当該細胞を、5%CO2の存在下で37℃でインキュベートした。
HL60細胞を、1.2×105個/mlで播種した。播種18時間後、二重反復試験において細胞を試薬で処理した。4日後、上記細胞を採取し、ニトロブルーテトラゾリウム還元アッセイを行った(Collins et al., 1979; J. Exp. Med. 149:969-974)。分化した細胞の百分率を、全200個の細胞を計数し、細胞内に黒〜青色ホルマザン沈着物を含有した数を記録し決定した。単球細胞への分化アッセイは、食細胞活性を測定して決定した(データ示さず)。
転写活性は、ルシフェラーゼレポーター遺伝子の上流に24−ヒドロキシラーゼ(24Ohase)遺伝子プロモーターで安定化トランスフェクションしたROS17/2.8(骨)細胞で測定した(Arbour et al., 1998)。細胞を一定範囲の用量で与えた。投与16時間後、細胞を採取して、ルミノメーターを用いてルシフェラーゼ活性を測定した。
腸管カルシウム輸送及び骨カルシウム動員
離乳雄Sprague-Dawley ラットを、Diet 11(0.47%Ca)飼料+AEKで1週間、Diet 11(0.02%Ca)飼料+AEKで3週間給餌した。次に、上記ラットを、0.47%Ca含有飼料を1週間、次に、0.02%Ca含有飼料で2週間へと切り換えた。用量投与は0.02%カルシウム飼料の最終週で開始した。ip用量を4回連続約24時間隔で与えた。最終用量から24時間後、頸部を切断して血液を回収し、血清カルシウム濃度を骨カルシウム動員の指標として決定した。腸管の始めの10cmもまた外転腸嚢法(everted gut sac method)を用いた腸管カルシウム輸送分析のために回収した。
VDR結合、HL60細胞分化及び転写活性
18,19−ジノル−2MP(Ki=2.2×10−10M)は、完全長組換えラットビタミンD受容体への結合について[3H]−1,25−(OH)2D3と競合する機能が、天然ホルモン1α,25−ジヒドロキシビタミンD3(Ki=4.1×10−11M)と比較した活性が僅かに低い(図1)。化合物18,19−ジノル−2MP(EC50=1.5×10−8M)は、HL60分化を促進する場合、1α,25−ジヒドロキシビタミンD3(EC50=3.2×10−9M)と比較して、活性がやや低い(図2を参照)。さらに、化合物18,19−ジノル−2MP(EC50=1.5×10−8M)は、骨細胞で1α,25−ジヒドロキシビタミンD3(EC50=3.2×10−9M)より転写活性がやや低い(図3を参照)。上記結果は、18,19−ジノル−2MPが、細胞分化を起こす場合及び細胞増殖を抑制する場合に直接的な細胞活性を有することから、乾癬に極めて有効であろうことを示唆する。上記データは、さらに、18,19−ジノル−2MPが、特に、白血病、結腸癌、乳癌、皮膚癌及び前立腺癌に対する抗癌剤として、さらに、乾燥皮膚(皮膚水和の欠如)、過度の皮膚たるみ(不十分な皮膚引き締め)、不十分な皮脂分泌及びしわ等の皮膚状態に対する活性が有意であろうことを示す。それは、さらに、続発性副甲状腺機能亢進を抑制する場合に極めて活性であると考えられる。
低カルシウム飼料(0.02%)を給餌されたビタミンD欠乏ラットを用いて、腸管及び骨の18,19−ジノル−2MP及び1,25(OH)2D3の活性を調べた。予想されるように、天然ホルモン(1,25(OH)2D3)では、全ての用量で血清カルシウムレベルが増加した(図4)。図4は、18,19−ジノル−2MPが、骨からカルシウムを動員する場合の活性があっても低く、その活性は2MPとほぼ同等であることを示す。18,19−ジノル−2MPを780pmol/日で連続4日間投与しても、骨カルシウムの動員は起こらず、18,19−ジノル−2MPの量を2340pmol/日又は7020pmol/日に増やしても実質的な影響はなかった。
