VDR親和性評価
VDRの評価は市販の測定評価キット、例えばインビトロジェン社が販売するポーラースクリーン ビタミン D レセプター コンペティター アッセイ レッド(POLARSCREEN VITAMIN D RECEPTOR COMPETITOR ASSAY,RED (invitrogen) Cat.No.PV4569)を用いて、以下の手順で、評価を行った。
ヒト骨芽細胞(HOS細胞)におけるVDR転写活性
(1)レポーターベクターはpGL3ベクター(promega社)を用い、ルシフェラーゼ遺伝子の上流に、文献既知の方法(Ozonoら、ザ・ジャーナル・オブ・バイオロジカル・ケミストリー(The Journal of Biological Chemistry )、265巻、21881-21888頁、1990年)で得られるヒトオステオカルシン遺伝子プロモーター部分の配列を、HOS細胞(ATCCより入手)から取得したcDNAよりクローニングし、組み込んで構築した。発現ベクターはpCDNA3ベクター(Invitrogen社)にヒトVDRおよびヒトRXRをコードするDNA配列を挿入して構築した。HOS細胞は10%FBSを含むDMEM培地で37℃、5%CO2の条件で培養し、2日あるいは3日ごとに継代した。
(2)継代培養していた細胞を遠心回収し、無血清、フェノールレッド不含のDMEM培地に4×105cells/mlの密度で分散させ、96ウェルプレートに0.1mL/ウェルで播種した。この系に、(1)に記載した各種ベクターをLipofectamine2000(Invitrogen社)試薬を用いてウェルあたり0.05mL添加した。37℃で3時間インキュベートした後、各ウェルに各種濃度の被験化合物エタノール溶液あるいはコントロールとしてエタノールを2μLずつ添加した。37℃で24時間インキュベートした後、培地を取り除き、PBS(-)で一度洗浄した後、DualGlo-Luciferase Assay kit(Promega社)を用いて、ルミノメータ(ベルトールド社)によりルシフェラーゼ活性を測定した。
骨粗鬆症モデル(卵巣摘出)ラットにおける骨密度増強作用(比較試験)
12週齢のSD系雌性ラット(チャールズリバージャパン)の両側卵巣を摘出し、4週間放置後、本発明の化合物、並びに国際公開WO01/62723号パンフレットに記載されている2α-(3-ヒドロキシプロピル)オキシー1α,25-ジヒドロキシビタミンD3を、週5回、4週間、それぞれ経口投与した。最終投与24時間後、エーテル麻酔下で採血を行い、安楽死させた。麻酔下において、第4第5腰椎の骨密度を二重X線骨塩量測定装置(QDR-2000,HOLOGIC)を用いて測定した。比較のために、偽手術(sham)群(開腹手術をするが卵巣摘出せず、試験化合物の投与を行わない)と卵巣摘出(OVX)群(卵巣摘出するが試験化合物の投与を行わない)についても解剖時において腰椎の骨密度の測定を行った。また、各群における血清中のカルシウム濃度の測定も行った。
