Description
疎水性カプロイル基および親水性カルボキシメチルで修飾した両親媒性キトサン誘導体の製造
まず、室温で、5gのキトサン(Mw=215,000g/mol、脱アセチル度80〜90%、Aldrich−Sigmaから購入)を、イソプロパノール(50mL)に懸濁させ、30分間撹拌した。得られた懸濁液を水酸化ナトリウム水溶液(12.5mL)に徐々に混合して混合溶液を得、混合溶液における水酸化ナトリウムの濃度を調整することによって親水性官能基のグラフト(graft)量を制御できる。ここで、混合溶液には13.3Mの水酸化ナトリウムが含まれた。次に、この混合溶液をクロロ酢酸(chloroacetic acid)と反応させ、水溶性の親水性カルボキシメチルで修飾したキトサン(carboxymethyl−modified chitosan)を得、乾燥させた。
両親媒性キトサン誘導体により薬物を被覆する
実施例1で製造した両親媒性キトサン粉末を0.5mg秤量し、200μLの0.1%のデメトキシクルクミン(メタノールに溶解する)に添加し、振とう機で少し混合した後、540μLの蒸留水を添加し、さらに60μLのpH10.5の蒸留水を添加し、最後に200μLの0.1%のシスプラチン(cisplatin)(水に溶解する)を添加し、12時間撹拌し、水溶液の全体のpHが6〜7になるようにさせ、二種類の薬物(デメトキシクルクミンおよびシスプラチンを含む)で被覆したナノ粒子を製造した。その後、必要に応じて、その溶液をそのまま使用してもよく、その溶液を(例えば蒸留水で)希釈または濃縮してから使用してもよい。
二種類の薬物で被覆したナノ粒子の被覆率試験
合成された二種類の薬物で被覆したナノ粒子を、濃縮遠心管に入れ、回転速度4000rpmで30分間遠心した。
濃縮遠心管の下澄液を20倍希釈し、1:1の割合で0.14% o−フェニレンジアミンのジメチルホルムアミド溶液と混合し、100℃で30分間加熱した後、−20℃の冷蔵庫に10分間放置して冷却し、最後に溶液をUV−可視光で波長705nmにおけるピークを検出し、換算して被覆されていないシスプラチン含有量が分かり、さらにシスプラチンの被覆率が分かる。
濃縮遠心管のろ過膜上のナノ粒子を蒸留水で再溶解し、この溶液とメタノールとを1:1の割合で混合し、HPLCで分析した。流速1mL/minでC18を固定相とし、アセトニトリルと0.3%FA(50:50,v/v)を移動相とし、波長425nmの条件で検出し、デメトキシクルクミンの濃度を換算して薬物被覆率を得た。
抗体を二種類の薬物で被覆したナノ粒子に連結させる
適量の抗体(抗−CD133)と0.01%50μL架橋剤(EDC)を上記二種類の薬物で被覆したナノ粒子溶液に添加し、5時間撹拌し、抗体を上記二種類の薬物で被覆したナノ粒子表面に連結させ、製造された二種類の薬物で被覆したナノ粒子の直径は190nmである。下記表1に、両親媒性キトサンナノ粒子(以下、CHCとも称する)、二種類の薬物で被覆したナノ粒子(以下、CHC/DMC−CDDPとも称する)、および抗体を連接した二種類の薬物で被覆したナノ粒子(以下、CHC/DMC−CDDP−抗体とも称する)の直径およびゼータ電位(zeta potential)をまとめた。
本発明のCHC/DMC−CDDPおよびCHC/DMC−CDDP−抗体のナノ粒子で癌細胞を殺す細胞生存率の試験
肺癌幹細胞(A549−ON)を24ウェルのプレートに、各ウェルごとに1×105個の細胞で培養し、異なる量の遊離型DMC−CDDP組み合わせ(free drug)(図4において、左から右までの量は、3.25−75g/mL、7.5−150g/mL、7.5−300g/mL、15−300g/mLおよび20−600g/mL)、CHC/DMC−CDDPナノ粒子(図4において、左から右までの量は、1.25−95g/mL、3−125g/mL、5−200g/mL、6−250g/mLおよび9−265g/mL)、およびCHC/DMC−CDDP/抗−CD133ナノ粒子(図4において、左から右までの量は、1.25−95g/mL、3−125g/mL、5−200g/mL、6−250g/mLおよび9−265g/mL)を、肺癌幹細胞に与えて24時間培養した後、3−(4,5−ジメチルチアゾール−2−イル)−2,5−ジフェニルテトラゾリウム臭化物(以下、MTTとも称する)で細胞生存率を分析した。図4は、三種類の薬物/担体の異なる組み合わせの細胞生存率に対する影響を示し、図4に示すように、Y軸はコンビネーションインデックス(combination index、以下、CIとも称する)であり、前記CI値が1より小さい場合、相乗効果があることを意味し、Faは細胞死亡率を示し、数値が1に近づくほど細胞死亡率が高く、より好ましい癌細胞を殺す効果を奏することを意味する。図4から分かるように、CHCで被覆されていない薬物(すなわち、遊離型DMC−CDDP組み合わせ)は相乗効果がなく、二種類の薬物を同時に使用して癌細胞を殺す効果を向上させることができない。また、CHCで被覆した二種類の薬物は、一部の量(CHC/DMC−CDDP:6−250g/mLおよび9−265g/mL、CHC/DMC−CDDP/抗−CD133:5−200g/mL、6−250g/mLおよび9−265g/mL)において二種類の薬物の相乗効果を示し、優れた癌細胞を殺す効果があったことが明らかである。図5は、CHC/DMC−CDDPナノ粒子およびCHC/DMC−CDDP/抗−CD133ナノ粒子の細胞生存率に対する影響、すなわち、CHC二種類の薬物で被覆した抗体が連結された/連結されていないナノ粒子の肺癌幹細胞を殺す効果を示し、図5から分かるように、CHC/DMC−CDDP/抗−CD133ナノ粒子(抗体にグラフトした)は、肺癌幹細胞の生存率を効果的に低下させることができる。
