7α−エチル−3−メトキシ−エストラ−1,3,5(10)、15−テトラエン−17−オン(3)の調製
7α−エチル−3−メトキシエストロン1を、17β−17−(アセチルオキシ)−エストラ−4,6−ジエン−3−オンおよび臭化エチルマグネシウムから、欧州特許出願公開第0869132号に記載の方法(実施例1およびスキームI、化合物1〜5を参照)と類似の方法で調製した。
THF(3ml)中の7α−エチル−3−メトキシエストロン1(1g)溶液を、−60℃で、LDA溶液[ヘプタン中のn−BuLiの1.6M溶液(4.7ml)を、−50℃でTHF(15ml)中のジイソプロピルアミン(2.1ml)に加えることで調製した。]に液滴状で加えた。混合物を−60℃で1/2時間攪拌し、次いで塩化トリメチルシリル(2ml)で処理した。反応混合物を1/2時間0℃で温め、次いでNH4Cl10%水溶液(100ml)に注ぎ、酢酸エチルで抽出した。洗浄、乾燥(Na2SO4)し、引き続き濃縮することで粗製シリルエノラート2(1.1g)を得た。これはさらに精製することなく次の段階で使用された。
アセトニトリル(15ml)中の粗製シリルエノールエーテル2(1.1g)溶液に、Pd(OAc)2(750mg)を加えた。混合物を還流状態で15分間加熱した。次いで、水と酢酸エチルを加え、有機混合物を、セライトを通してろ過して生成物を酢酸エチルへと抽出した。このようにして分離した有機物を、短いシリカカラムを通すことにより精製し、ヘプタン/酢酸エチルを用いて溶離し、化合物3(710mg)を無色のオイルとして得た。Rf(1)0.47、Rf(2)0.80、Rf(3)0.46、溶離液はヘプタン/酢酸エチル8/2を使用。NMR(CDCl3)、δ7.58(1H)、7.21(1H)、6.74(1H)、6.66(1H)、3.79(3H,CH3O)、1.11(s,3H,18−CH3)、1.00(t,3H,エチル)。
乾燥THF(5ml)中の溶液3(300mg)に対して、無水Cu(OAc)2(100mg)を加えた。混合物を、−70℃においてで2分間攪拌し、その後塩化メチルマグネシウム(THF中の1M溶液5ml)を液滴状で加えた。反応物を0℃において1/2時間温め、10%NH4Cl溶液を加えて急冷した。生成物を、酢酸エチルを用いて抽出し、次いで、溶離液としてヘプタン/酢酸エチルを用いて、シリカゲル上でクロマトグラフィーによって精製し、4をm.p.が120〜122℃の白色固体(280mg)として得た。NMR(CDCl3)δ7.22(1H)、6.73(1H)、6.65(1H)、3.79(1H)、1.20(3H,s,18CH3)、0.98、0.96(6H,2t,,7αおよび15βエチル)。
ジクロロメタン(1ml)中の溶液4(270mg)に対して、BF3.DMS錯塩(800μl)を加えた。混合物を1.5時間攪拌し、次いで氷水に注ぎ、酢酸エチルで抽出した。このようにして得た残留物をエーテル/ヘプタン(1/1)を用いて完全に粉砕し、5(250mg)を薄いバラ色の無定形固体として得た。Rf0.27(ヘプタン/酢酸エチル8/2)。この物質をDMF(3ml)中で溶解し、イミダゾール(300mg)を、続いて塩化t−ブチルジメチルシリルを加えた。室温で2時間攪拌してシリル化を完結させた。反応物を、氷水を加えることで急冷し、続いて生成物を酢酸エチルで抽出した。短いシリカカラム上のクロマトグラフィーで精製し(ヘプタン/酢酸エチル9/1)、硬い無色のオイルとして6(220mg)を得た。Rf0.60(ヘプタン/酢酸エチル8/2)。NMR(CDCl3)δ7.12(1H)、6.62(1H)、6.18(1H)、1.03(s,3H,18−CH3)、0.98(s,9H,tert.ブチルシリル)、0.97,0.95(2t,6H,7αおよび15βエチル)、0.20(s,6H,CH3−シリルエーテル)。

A.卵胞期様変化
・緩んだ子宮内膜間質
・一直線の子宮内膜線
・子宮内膜線上皮肥大
・有糸分裂像
・子宮筋層肥大
・初期の血管形成(発芽または初期増殖)
・基礎的分泌
B.黄体期様変化
・仮性脱落膜肥大間質細胞
・子宮内膜線のコイリング
・後期血管形成(らせん動脈の形成)
・子宮内膜線上皮の空胞形成
・管腔の分泌
C.卵巣摘出または非刺激(萎縮性)子宮内膜
・小型子宮内膜間質
・子宮内膜線上皮の萎縮
・子宮内膜線の萎縮
・子宮筋層の萎縮
上記所見のそれぞれの重症度を、等級付け尺度を用いて採点した。
・等級0:所見なし
・等級1:最小量、ほとんどない、非常に小さい
・等級2:微々たる、わずかな、小さい
・等級3:中程度の、中程度の数値、中程度の寸法
・等級4:著しい、多い、大きい
・等級5:大量の、多数、大きな寸法
それぞれの動物にこの等級付けを行った。次いで、処置グループ当たりの平均得点を各特性について計算した。最後に、平均個別特性から、萎縮性、卵胞期様または黄体期様のカテゴリー毎に平均得点を計算した。化合物に関する好都合な子宮内膜安全プロフィールは、より多い黄体期様特性および/または萎縮性子宮内膜と相まった化合物誘発の卵胞期様活性が少ないことと特徴付けられる。
