金属錯体化合物(II)の合成
(第1の合成例)
金属錯体化合物(II)を次の反応式に従って合成した。
グリシン・メチル・エステル一塩酸塩(glycine methyl ester monohydrochloride)(10.0g, 0.079mol)を含むギ酸エチル(ethyl formate)溶液(60mL)にP-TsOH (10 mg)を加えた。そして、その溶液を加熱して沸騰させた。沸騰中にトリエチルアミン(triethylamine)を数滴滴下し、その混合液を24時間還流した。その後、その溶液を室温まで冷却した。白いトリエチルアミン塩酸塩をろ過した。ろ過物を20mLまで濃縮した。得られた溶液をマイナス摂氏5度まで冷却し、ろ過を行った。ろ過物である、赤茶色の濃縮溶液(化合物1)を得た。
化合物1に、CH2Cl2 (20mL)を溶かした。その後に、ethane-1,2-diamine(1.2g)、そして、酢酸(HOAc)(20μL)を加えた。反応させた混合溶液を6時間還流させた。そして、反応混合溶液を室温まで冷却し、4グラムの黄色い油状の濃縮物(化合物2)を得た。得られた化合物2の純度を、シリカゲルを用いたフラッシュコラムクロマトグラフィーによって向上させた。
メタノール(50ml)の中に化合物2、triethylamineを入れ、10mlメタノールの中に、金属塩化物(鉄サレン錯体化合物の合成の際は、FeCl3(4H2O)である。)溶液を窒素雰囲気下で混合した。室温窒素雰囲気で1時間混合したところ茶色の化合物が得られた。その後、これを真空中で乾燥した。得られた化合物をジクロロメタン400mLで希釈し、塩性溶液で2回洗浄し、Na2SO4で乾燥させ、真空中で乾燥させて化合物0(金属錯体化合物(II))を得た。
金属錯体化合物(II)を次の反応式に基づいて合成した。
(1.4 g, 5 mmol)を加えたところ、青白い緑の溶液が得られた。混合溶液を、8時間、室温、窒素雰囲気で攪拌したところ、色が徐々に茶色になった。その後、溶液を蒸発させてその体積を半分にした後、同体積の水を加えた。次いで、真空引きでメタノールを蒸発させたて茶色の塊を得た。その塊を集めて水で洗浄し、真空引きで乾燥したところ目的の化合物0(鉄錯体化合物(II))が360mg得られた。
金属錯体化合物(II)を次の反応式に基づいて合成した。
金属錯体化合物(III)の合成
金属錯体化合物(III)を次の反応式に基づいて合成した。
金属錯体化合物(IV)の合成
金属錯体化合物(IV)を次の反応式に基づいて合成した。
前記(V)〜(XI)の化合物は、国際公開第2010/058280号公報43〜47頁に記載の方法によって合成する。側鎖である臭素、又は、メトキシル基の主骨格への付加は、サレンに金属錯体の結合を形成する際に、ベンゼン環のOH基とはパラの位置でベンゼン環に結合している保護基(NHBoc)を臭素、又は、メトキシル基で置換する。(c,d),(e,f)がアントラセンを構成する(VIII)及び(IX)の化合物では、出発物質として、パラニトロフェノールに代えて、下記化合物を使用する。
(a,h)がシクロヘキサンを構成する金属サレン錯体(VI)、さらに、(a,h)がベンゼンを構成する金属サレン錯体(VII)の合成については、Journal of
thermal Analysis and Calorimetry, Vol.75(2004)599-606 のExperimental
の600Pに記載の方法によって、金属と配位結合する前の目的のサレンを作成する。
下記(1)の化合物は、鉄の2価のサレン錯体化合物である。本化合物はがん細胞の中に存在する活性酸素と結合して酸素ラジカルをトラップするにより、2価から3価に変化する。ここでは、下記(1)の化合物ががん細胞から発生する酸素ラジカルをトラップする様子を3価の錯体を検出して発色するヘマトキシン(hamatoxylin)を用いて確認した。
(R1,R2,R3,R4は、いずれも「H」である。)
M3)を(1)式の鉄サレン錯体化合物(濃度1mM)の存在下で培養した。培養は丸型シャーレを用い、そのシャーレ(直径100mm)の下に磁束密度240mTの丸いボタン状の磁石(直径10mm)を置き、そのシャーレを24時間培養した(培地はPBS(リン酸緩衝生理食塩水)、培養時間24時間、培養温度37℃)。この培地をヘマトキシリンで染色した。
(1)脱パラフィン、脱キシレン、水洗を行う。
(2)核染色をヘマトキシリンで5-15分行う。
