Description
式中、Aは存在する又は存在せず、かつAは薬学的に許容される無機若しくは有機塩基、又は塩基性アミノ酸を表す。
1. 2−(4’−メトキシ−フェノキシ)−ニトロベンゼン(A)の製造
16g(0.129モル)のp−メトキシフェニル及び8g(0.143モル)の水酸化カリウムを秤り、マグネティックスターラーと、温度計と、冷却管とを備えた50mLの三つ口フラスコに加え、加熱し固体を溶解させた。少々冷却後、1g前後の活性銅及び15.8g(0.1モル)のo−クロルニトロベンゼンを加え、続けて1時間加熱還流し、内部温度を150℃前後になるように調節した。反応終了後、80℃で反応液を300mLの3%NaOHに移し、一晩放置し、黄色結晶が析出した。それを吸引ろ過し、蒸留水を用いて中性になるまで洗浄し、室温で乾燥させ、17.4gの粗生成物を得た。
(A)を適量な酢酸エチルで溶解し、ラネーニッケルの存在下、40℃で10kgの圧力下、接触水素化を行った。反応終了後、水素化反応液中の触媒をろ過除去し、ろ液を減圧濃縮し、粘着物を得た。得た粘着物を10%HCl溶液で溶解し、pHを4〜5になるように調節し、ろ過し、ろ液を冷却撹拌しながら25%NaOH溶液を用いてpHが9〜10になるようにアルカリ化した。静置後、有機層を回収し、水層を酢酸エチルで二回抽出し、有機層を併せた。無水硫酸マグネシウムで乾燥、ろ過し、ろ液を濃縮し、14gの粘着物(B)を得た。
10gの(B)を秤り、10mLの無水ピリジンとともに、スターラーと、温度計と、冷却管と、滴下漏斗とを備えた4つ口のフラスコに加えた。内部温度が75℃になるまで加熱し、ゆっくり6gの塩化メタンスルホニルを滴下し、内部温度を85〜90℃になるように調節し、続けて1時間反応させた。反応終了後、反応液を18%塩酸水溶液に移し、ろ過し、ろ液を酢酸エチルで3回抽出し、水で洗浄して中性にした。1晩無水硫酸マグネシウムで乾燥した。ろ過し、減圧蒸留によって酢酸エチルを除去した。冷却放置し、粗2−(4’−メトキシ−フェノキシ)−アニリンを得た。

4−ニトロ−2−[(4’−メトキシ)−フェノキシ]−メタンスルホニルアニリン(S 6 )とPVP K30 との混合物又は水素結合による複合体(S 6 K30−1、S 6 K30−3、S 6 K30−5)の製造
3.6g(0.01227モル)の2−(4’−メトキシ−フェノキシ)−メタンスルホニルアニリン、30mLの氷酢酸、及び12mLの無水酢酸を撹拌器と、温度計と、滴下漏斗とを備えた100mLの三つ口フラスコに加え、撹拌し、85〜90℃になるまで加熱し、ゆっくり3gの硝酸を滴下した後、90℃で4時間撹拌した。放置し冷却させ、黄色結晶を析出させた。この結晶をシリカゲルカラムに添加し、ジクロロメタンで溶出し、Rf=0.796のフラクションを回収した。併せた溶出液を減圧濃縮し、淡黄色固体を得た。この固体をエタノールで再結晶し、3.5gの淡黄色結晶(S6)を得た(収率:84.3%、融点:130〜132℃)。
元素分析: 理論値 C:49.70%、 H:4.70%、 N:8.28%
実測値 C:49.62%、 H:4.11%、 N:8.07%
DSC曲線から、S6は132.03℃においてシャープな吸熱ピーク(融点)を有することが分かった。PVPK30の吸熱ピークは86.55℃であることが分かった。S6とPVPK30との物理的な混合物であるS6PM1、S6PM3、及びS6PM5は、それぞれ127.84℃、127.1℃、及び129.15℃においてS6の吸熱ピークを有することが分かった。これに対して、S6K30−1及びS6K30−3のDSC曲線中、S6の吸熱ピークはが依然と存在するが、それぞれ異なる程度の低温へのシフトがあり、また、S6K30−5のDSC曲線中、S6の吸熱ピークが完全に消失していることがわかった。これは、S6結晶は完全にPVPK30に抑制され、無定形物に形成していることを示唆している。
6.8gの4−ニトロ−2−(4’−メトキシ−フェノキシ)−メタンスルホニルアニリンを40mLのジクロロメタンに溶解し、撹拌下、室温で3.2gのトランス−4−メチル−シクロヘキシルアミンを滴下し、1時間加熱還流し反応させ、黄色の針状結晶を析出させた。放置し、冷却させ、結晶をろ過し回収し、エタノールで3回洗浄した後、40℃で真空乾燥し、6.7gの4−ニトロ−2−[(4’−メトキシ)−フェノキシ]−メタンスルホニルアニリンのトランス−4−メチル−シクロヘキシルアミン塩を得た(融点:159〜161℃)。
元素分析: 理論値 C:55.86%、 H:6.47%、 N:9.31%
実測値 C:55.88%、 H:6.40%、 N:9.12%
4−ニトロ−2−[(4’−メトキシ)−フェノキシ]−メタンスルホニルアニリン誘導体(S 6 及びS 9 )のマウスにおける抗炎症及び鎮痛作用
後述の生物学実験において、主に各化合物のマウスの酢酸による捻転反応及びカラゲニン足蹠浮腫に対する作用を観察した。ニメスリドをポジティブコントロールとして使用し、それぞれの治療効果を評価した。その結果を表1〜5に示す。
