Abstract
Description
特に、2−ニトロイミダゾール誘導体のうち、次式(1)
また、化合物(1)は、低酸素性細胞に対する放射線増感作用以外にも、核酸水酸化物消去作用(特許文献4)、アポトーシス・シグナル保持作用(特許文献5)などを有し、癌治療において有用な薬剤である。
これらの化合物(1)は何れも結晶性に優れる、水溶性も脂溶性も有する、腫瘍親和性が高いなどの特性を有しており、これは非環状糖ヌクレオシド類似構造に起因するものであると言われている。
更に、化合物(1)の水性担体溶液の安定性が、室温以上では損なわれやすい為、5℃などの低温保存しなければならず、低温保存条件が更に溶解性を制限するという問題があった。
加えて、凍結乾燥製剤であっても、わずかに含有する水分の安定性への影響は少なくないという問題があった。
これより少ないと、放射線増感効果の点で好ましくなく、また、多いと放射線増感効果及び溶解性の点で好ましくない。
製剤としては、経口投与製剤、注射製剤何れもが可能であるが、代謝が早い点で、注射製剤が好ましい。当該注射製剤としては、点滴投与用の製剤が好ましい。これは、有効成分である化合物(1)の投与量が多いため、投与に必要な製剤量が多くなり、一時の投与では危険が生じる場合があるためである。この様な注射用製剤としては、溶液形態でも、凍結乾燥形態でも特に制限はないが、安定した溶解性が得られる点で、溶液形態であることが好ましい。
この様な任意成分としては、例えば、マクロゴールの様な多価アルコール類、塩化ナトリウムのような等張化剤、リン酸塩のような緩衝剤、結晶セルロースや澱粉のような賦形剤、ポリオキシエチレン硬化ヒマシ油のような非イオン界面活性剤、ラウリル硫酸ナトリウムのようなアニオン界面活性剤、アラビアゴムのような増粘多糖類、ステアリン酸マグネシウムのような滑沢剤、着色剤、矯味矯臭剤、ヒドロキシプロピルセルロースのような結合剤、「オイドラギット」(登録商標)の様な被覆剤等が例示できる。溶液形態の注射用の医薬組成物において、特に好ましい形態は、必須成分とベヒクル以外の成分を含有しない形態である。
下記に示す処方に従って、本発明の医薬組成物である、点滴投与用の注射液剤を製造した。即ち、処方成分を30℃で攪拌しながら溶解させ、同時に溶解に要した時間を計測した。溶解に要した時間は表2に示す。これより、本発明の医薬組成物は、1−(1−ヒドロキシメチル−2,3−ジヒドロキシプロピル)オキシメチル−2−ニトロイミダゾール(化合物1)の溶解性を高める作用を有することがわかる。尚、対照例1はクレアチニンを添加しないものとした。
実施例1と同様に、下記に示す処方に従って、本発明の医薬組成物である、点滴投与用の注射剤(医薬組成物4〜6)を製造した。
<試験例1>
前記医薬組成物4〜6、対照例2を55℃の過酷条件で9日間保存し、化合物(1)の含有量をHPLCで測定し、これを5で除して100を乗じ、含有率(%)を算出した。結果を図1に示す。本発明の医薬組成物は安定性に優れることがわかる。尚、HPLC条件は、ODSカラム4.6mm×250mm、カラム温度40℃、流速1ml/分、移動相1%メタノール水溶液、検知紫外部320nmであった。
下記に示す処方に従って、溶液を作成し、これをバイアル瓶に無菌状態で充填し、これを凍結乾燥させて、微細結晶を含むアモルファスの注射用の凍結乾燥製剤である、本発明の医薬組成物7を得た。
<試験例2>
医薬組成物6と医薬組成物7と対照例2とを55℃に5日間保存し、実施例3と同様の含有率を算出した。結果を図2に示す。凍結乾燥製剤においても同様に安定性向上効果が得られた。
<試験例3>
放射線増感効果をマウス扁平上皮癌細胞SCCVIIを用いてMicronucleus法にて検討した。マウス扁平上皮癌細胞SCCVIIを20分間 95%N2+5%CO2で通気し低酸素状態にした後、PBS及び次に示す製剤の存在下で、X線(0、1、2、3Gy)を照射した。製剤は実施例2の対照例2、医薬組成物6、医薬組成物6のクレアチニンをサリチル酸ナトリウムに置換した比較例1、安息香酸ナトリウムに置換した比較例2である。照射後、細胞を洗浄し、cytochalasin B 存在下にて約24時間培養し、二核細胞を形成させた。これを固定・蛍光染色して二核細胞数及び微小核数をカウントし微小核発生頻度を求めた。結果を図3に示す。
図3中、クレアチニンは医薬組成物6を、サリチル酸ナトリウムは比較例1を、安息香酸ナトリウムは比較例2を表す。PBS及びいずれの製剤についても、非照射群において、微小核発生頻度に変化は認められず、細胞への直接的な影響は認められなかった。すなわちクレアチニンなど添加剤を加える事による細胞への直接的な毒性は認められなかった。また、照射群においては、いずれの製剤でも低酸素放射線増感効果が認められたが、添加剤を加えない対照例2と比べれば、本発明の製剤である医薬組成物6のみ増感効果に変化を与えていないことがわかる。
