Description
1ppmのトリメチルアルシンオキシド(TMAO)20μL,100mMのグルタチオン還元型(GSH)50μL、及び7.4μMのヨード酢酸135μLを混合した。混合後のTMAO,GSH及びヨード酢酸の溶液中の濃度はそれぞれ0.2μM,5mM,1mMである。この混合液205μLを、100mMのりん酸−クエン酸緩衝液(pH3,4,5,6,7,8)795μL中、37℃で反応させ、HPLC−ICP−MSで反応後の混合液中のTMAO、アルセノベタイン(AB)など砒素化合物の量を分析した。HPLC−ICP−MSクロマトグラムを図1〜4に示す(図1:反応時間4時間、図2:反応時間24時間、図3:反応時間100時間、図4:反応時間439時間、A:標準サンプル、B:pH3、C:pH4、D:pH5、E:pH6、F:pH7、G:pH8)。図1〜4のクロマトグラムについて、TMAO、ABなどに帰属されるピークの面積を所定濃度の標準サンプルの面積と比較することにより、濃度を定量した。表1に反応後の混合液中の砒素化合物の濃度を示し、図5に表1をグラフ化したものを示す。図5中、縦軸( Arsenic concentration)は、砒素化合物の濃度(ng/mL)を示し、横軸(Time)は反応時間を示す。
表1から明らかなように、TMAOが有機ハロゲン化合物(ヨード酢酸)と反応することによって、より安全かつ安定なアルセノベタイン(AB)へ変換されているのが分かる。なお、表1、図5におけるUNは未知化合物である。以下の表、図においても同様である。 また、表1の砒素化合物の濃度について、相対濃度を百分率で計算した結果を表2及び図6に示す。図6中、縦軸(Relative concentration)は、砒素化合物の相対濃度(%)を示し、横軸(Time)は、反応時間を示す。
次に、グルタチオン還元型(GSH)の代わりにシステイン(Cys)を用いることを除いて、実施例1と同様に行った、トリメチル化合物の無害化について説明する。ここでは、反応温度は37℃の他に、50℃,80℃についても調べた。
還元剤としてグルタチオン還元型またはシステインを用い、有機ハロゲン化合物としてヨード酢酸エチルを用いることを除いて、実施例1と同様に行った、トリメチル化合物の無害化について説明する。反応温度は、37℃、50℃、80℃、反応時間は4時間、16時間、54時間であった。反応経路は以下のとおりである。
実施例3のサンプル(TMAOIA44;還元剤としてシステインを使用)100μLに6N塩酸100μLを添加し、表7に示す反応条件で反応させた。反応式は以下のとおりである。
本実施例では、亜ヒ酸のメチル化について説明する。
〔反応スキーム〕
As2O3→ AsBr3
〔実験操作〕
亜ヒ酸As2O3酸(26.5g)、硫黄(6g)、臭素Br2
(64g)を300mlフラスコに加えて徐々に加熱した(急激に加熱すると、Br2の蒸気が蒸発揮散するので注意して過熱する)。約7時間後、立ち上がる蒸気がBr2による褐色の色を示さなくなるまで反応させた。次のようにして精製を行った。生成した三臭化砒素には過剰のBr2を溶解している恐れがあるので砒素粉末を加えて蒸留精製した(収率:>90%)。性質:無色、潮解性、斜方晶系柱状晶、融点:31.2℃、沸点:221℃、比重:3.54(25℃)。湿気を含んだ空気中で発煙し、水を加えると加水分解を起こした。塩酸、二硫化炭素に可溶。毒性は三塩化砒素と同じく亜ヒ酸型であるが、刺激性は三塩化砒素ほど強くない。
〔反応スキーム〕
As2O3+6HCl → 2AsCl3 +3H2O
〔実験操作〕
亜ヒ酸(200g)をスターラーの付いた2lの三口フラスコに入れ、濃塩酸700mlを加えてかき混ぜながら、濃硫酸200mlを徐々に滴下した。この濃硫酸の滴下により、上の反応式で生成する水が脱水されて、反応は右に進み、生成した三塩化砒素は、相分離を起してフラスコの底に沈んだ。濃硫酸の滴下が終了した後、フラスコを加熱して蒸留した。留出は85℃から始まったが、90-107℃の留分をとった。流出液を冷却すると、三塩化砒素層(下層)とHCl層(上層)に分離したので分液ロートにより、三塩化砒素を分離した。収量:150ml、収率:89%、純度:99%以上。
〔反応スキーム〕
AsBr3 → AsMe3
〔実験操作〕
完全に乾燥したジブチルエーテル(200-300ml)に、マグネシウム(12.2g)、ヨウ化メチル(71g)とを加えて、ヨウ化メチルマグネシウムのエーテル溶液を作製し、それを−20℃に冷却しながら、三臭化砒素(50g)をエーテル(100ml)に溶かしたものを徐々に加えた。途中で黄色の沈殿を生じるがやがて消失した。その後、全体を炭酸ガスの気流の中で、水浴上から蒸留して、トリメチルアルシンのエーテル溶液を得た(沸点:70℃、液体)。
〔反応スキーム〕
ArCl3 +3MeLi→ ArMe3 + 3LiCl
〔実験操作〕
トリメチルアルシンは揮発性があるので(沸点:52℃)、保護マスクを使用した。メチルリチウムのジエチルエーテル溶液(500ml、0.8mol/l)と無水ジブチルエーテル(CaH2で精留したもの、400ml)をアルゴン気流下で反応器に入れた。ジブチルエーテルに溶解した三塩化砒素(13.6ml、0.16mol)をゆっくりと反応器内に添加した。アルゴン雰囲気下で、反応混合物を12時間反応させ、トリメチルアルシンを蒸留して、-35℃に保持したフラスコに採取した。収率:99%。
次に、ジメチルアルシン酸のメチル化について説明する。
〔反応スキーム〕
O=AsMe2(OH) → IAsMe2
〔実験操作〕
(1)ジメチルアルシン酸からジメチルヨウ化砒素の合成
ジメチルアルシン酸(250g)とヨウ化カリウム (800g)を水(1L)に溶解し、二酸化硫黄(SO2)を飽和させた。これに希塩酸(濃塩酸500mlと水500mlを混合して調整)をゆっくりと添加した。素早い還元反応が起こり、黄色オイル状のジメチルヨウ化砒素が分離した。反応終了は、硫黄の分離した時点で判断した。分離したオイル相を塩化カルシウムで乾燥し、蒸留して純粋なジメチルヨウ化砒素を得た(収量:380g、収率:90%)。沸点:154-157℃、融点:-35℃(青黄色結晶)。
〔反応スキーム〕
IAsMe2 → AsMe3
〔実験操作〕
窒素雰囲気で、乾燥したジブチルエーテル(100ml)中に、マグネシウム(3.1g)の懸濁液を攪拌して作製し、これにヨウ化メチル(17.0g)を加えて、グリニャール試薬を作製した(液A)。この濁った液体(液A)を-8℃に冷却し、ジブチルエーテル(100ml)に溶解したジメチルヨウ化砒素(30g、129mmol)の溶液(液B)を1.5時間かけて滴下した(液C)。この操作の終了時に温度は、-2℃に上昇し、溶液(液C)は、2層に分離した。水(120ml)に塩化アンモニウム(30g)を溶かした溶液を作製し、窒素を吹き込み、酸素を除いた後、液Cに30分かけて滴下した(液D)。液Dを窒素気流下、大気圧下で蒸留した。トリメチルアルシンを含んでいる沸点55-88℃で留出した留出物(16.5g、トリメチルアルシンとして138mmol)(液E)を、シュレンク管に採取し、A4モレキュラーシーブスで、窒素中で乾燥した。
トリメチルアルシンのトリメチルアルシンオキシドへ変換について説明する。
〔反応スキーム〕
Me3As → Me3As= O
〔実験操作〕
窒素雰囲気下で、乾燥したジエチルエーテル(15ml)中にトリメチルアルシン(4.5mmol)を混合し、過酸化水素(33%、0.7ml、7mmol)を加えた。窒素雰囲気下で、溶液を15分間攪拌した。反応終了後、反応混合物を濃縮した。濃縮物を真空下で、50℃に加熱乾燥し、50mlのジエチルエーテル−水(体積比1:1)から再結晶した(6.3mmol、収率:90%)。
ここでは、亜ヒ酸からトリメチルアルシンへの合成について説明する。反応式は以下の通りである。
実施例1〜4では、トリメチル化合物の無害化について説明したが、この実施例では、モノメチル化合物の無害化について説明する。
MMA溶液の代わりにジメチルアルシン酸(DMA)を用いたことを除いて、実施例9と同様に行った、ジメチル化合物の無害化について説明する。結果を表9に示す。
MMA溶液の代わりにトリメチルアルシンオキシド(TMAO)を用いたことを除いて、実施例9と同様に行った、トリメチル化合物の無害化について説明する。結果を表10に示す。
