Description
a)アルカリ水溶液下でヒアルロン酸またはこれらの塩を架橋剤を用いて架橋度0.1%〜200%で架橋させてヒアルロン酸誘導体を製造する段階;および
b)前記段階a)で製造された、架橋度0.1%〜200%を有するヒアルロン酸誘導体にDNA分画物を混合する段階。
実施例1:1gのヒアルロン酸(分子量:約200〜300万ダルトン)を10重量%濃度で0.25N NaOH溶液に溶かす。架橋剤は1,4−ブタンジオールジグリシジルエーテル(butanediol diglycidyl ether、BDDE)を使用し、使用された架橋度(degree of crosslinking)の定義は次の通りである:重量(BDDE)/重量(乾燥NaHA)。
製造された実施例1〜4および比較例1〜3の流動学的特性糾明のためにレオメータ(rheometer)を用いて分析した(比較例1:LGのイブアル、比較例2:BNCのキュゲル、比較例3:ガルデルマのレスチレン、比較例4:ヒュメディクスのエルラビエ)。
実施例1および実施例2のヒアルロン酸組成物のプレフィルドシリンジでの押出力を確認するために下記の条件で吐出荷重試験を行った。
図2a、bから分かるように、本発明による実施例2はヒアルロン酸架橋誘導体のみを含む実施例1に比べて低い吐出荷重結果値を示す。これによって、架橋されたヒアルロン酸誘導体にDNA分画物を混合すれば優れた弾性を示すだけでなく、施術時重要視されるゲルの柔らかさも増加させるのを確認した。
実施例1のヒアルロン酸および本発明による実施例2のヒアルロン酸注射用組成物内に含まれているPDRN分画物を分析するために電気泳動を行った。その結果を図3に示した。
実施例1−4および比較例1〜3のヒアルロン酸組成物の粒子の大きさと分布図を確認するために各試料3gを蒸留水15mLで希釈してBeckman Coulter LS Particle Size Analyzerを用いて0.375umから2000umの間の粒子を計数した。その結果を図4と表2に示した(比較例1:LGのイブアル、比較例2:BNCのキュゲル)。
実施例2と比較例1(LG生命科学のイブアル)のヒアルロン酸組成物をそれぞれコニカルチューブに5gずつ入れ、100IU/mLヒアルロニダーゼを2.5gの量で入れて均質に混合した後、37℃恒温水槽で反応させた。時間によるヒアルロン酸の粘度変化を力価用粘度計を用いて測定した。ヒアルロニダーゼ抵抗性が高いほど粘度比率の変化が少ない。粘度比率が高くなるほど粘度が減少するのを意味する。
図5から確認できるように、本発明による実施例2の組成物(HA含量:19.8mg/ml)は比較例1(HA含量:20.3mg/ml)に比べてヒアルロニダーゼ処理下で粘度比率が徐々に増加する傾向(より低い傾き)を示す(粘度比率が高くなるほど溶液の粘度が低くなるのを意味)。これにより、本発明のヒアルロン酸誘導体が市販されている注射剤の比較例1より優れた酵素抵抗性を有することが分かる。
実施例6:ヒアルロン酸(分子量:約200〜300万ダルトン)を10重量%濃度で0.25N NaOH溶液と混合し、BDDEを架橋度0.05%に該当する量を投入した後、架橋させた結果、ゲルが形成されなかった。
製造された実施例6〜14はレオメータ(rheometer)を用いて流動学的特性を比較した。周波数別貯蔵弾性係数(G’)、損失弾性係数(G”)、Tan(delta)、複合粘度(G)結果値を下記図6a−iおよび表3に示した。
