ヒドラジン水和物(44mmol)を、100ml Bis−Tris緩衝液(400mM、pH5.8)中のヒアルロン酸ナトリウム(440mg、1.1mmolカルボン酸基)の溶液に添加した。この混合物のpHを5.8に再調節した後(1N HCl)、DMSO(50ml)、続いてEDC(840mg、4.4mmol)を添加した。反応混合物を一晩攪拌した。続いてpHを7.0に調節した(0.1N NaOH)。
HA骨格上の反応性ヒドラジド部分の存在は、市販のアミン特異的同種二官能性架橋剤(例えば、DTSSP、DMS、グルタルアルデヒド、またはPEGDA)を使用する、個々のHA鎖間への多様な共有結合性架橋の導入を可能にする。
12%のヒドラジド基を含むヒドラジド官能化HA(実施例8において記載されるように製造した)を、0.2%〜1.5%に変化する濃度にて、PBS緩衝液(pH7.4)中に溶解した。
a.グルタルアルデヒドでの架橋。ヒドラジド−HA(16mg)をPBS(2ml、pH7.4)中に溶解した。次いで、PBS(200μl)で希釈したグルタルアルデヒドを添加した。ヒドラジド基:グルタルアルデヒドのモル比は、1:0.5であった。混合物を数秒間攪拌した。澄んだ透明なヒドロゲルが1分後に形成された。
b.PEGDAでの架橋。 ヒドラジド−HA(16mg)をPBS(2ml、pH7.4)中に溶解した。次いで、PBS(80μl)で希釈したPEGDA(6.8mg)を添加した。ヒドラジド基:PEGDAのモル比は、1:0.5であった。混合物を数秒間攪拌した。澄んだ透明なヒドロゲルが数分後に形成された。
c.DTSSPでの架橋。ヒドラジド−HA(16mg)をPBS(2ml、pH7.4)中に溶解した。次いで、DTSSP(5mg)を固体の形態において添加した。ヒドラジド基:DTSSPのモル比は、1:1.6であった。混合物を30秒間攪拌した。澄んだ透明なヒドロゲルが30分後に形成された。
d.DMSでの架橋。ヒドラジド−HA(20mg)をPBS(2ml、pH7.4)中に溶解した。次いで、H2O(100μl)中のDMS(13mg)の溶液を添加した。ヒドラジド基:DMSのモル比は、1:10であった。混合物を30秒間攪拌した。澄んだ透明なヒドロゲルが45分後に形成された。
コントロール実験を、上記の架橋化実験と並行して行った。ネイティブな(未修飾の)HAを、PBS緩衝液(pH7.4)中に10mg/mlの濃度にて溶解した。DMS、DTSSP、グルタルアルデヒド、またはPEGDAを、粘性混合物に添加し、そして室温で攪拌させた。溶液のゲル化は、経時的に観察されず、そして混合物成分は完全に水溶性のままであり、ヒドラジド官能化HAの不在下で、共有結合性の架橋はなんら生じなかったことを示す。
A.酸化AHでの架橋。H2O(3ml)中のヒアルロン酸ナトリウム(15mg、37.5μモル)の溶液に、過ヨウ素酸ナトリウム(8mg、37.5μモル)を添加し、そして反応を、2時間、室温にて進行させた。次いで、未反応の過ヨウ素酸塩を破壊するためにDTT(12mg)を添加した。15分後、反応混合物を透析チューブ(MWカットオフ3500ダルトン)に移し、そしてPBS(pH7.4)に対して徹底的に透析した。PBS(1ml、pH7.4)中のヒドラジド−HAの溶液(15mg、M.W.2.5×105、15%のヒドラジド基)を、上述の酸化HAの調製された溶液に添加した。混合物を短時間攪拌した。澄んだ透明なヒドロゲルが一晩で形成された。
B.酸化ゼラチンでの架橋。アルデヒド基を、以下の手順に従って、そのヒドロキシリジン残基を酸化することによりゼラチン中に作製した;過ヨウ素酸ナトリウム(7.5mg)を、酢酸緩衝液(500μl、50mM、pH4.5)中のゼラチン(25mg、Merck カタログ番号104080)の溶液に添加した。反応を3時間進行させた。次いで、未反応の過ヨウ素酸塩を破壊するために、DTT(38mg)を添加した。室温にて60分後、溶液を、酢酸緩衝液(500μl、50mM、pH4.5)中のヒドラジド−HA(5mg、M.W.3×106、20%のヒドラジド基)とともに混合した。澄んだ透明なヒドロゲルが、数分後に形成された。
酢酸緩衝液がPBS(pH7.4)により置き換えられた以外は同一の条件下で、さらなる実験を行った。しかし、このわずかに塩基性のpHでは、ヒドロゲルは12時間後にしか形成されなかった。
20%のヒドラジド基を含むヒドラジド官能化HA(実施例9において記載されるように製造した)を、0.2%〜1.5%にわたる種々の濃度にて、Bis−Tris緩衝液(100mM、pH4.75)中に溶解した。
a.ヒドラジド−HA(16mg)を、2ml Bis−Tris緩衝液(100mM、pH4.75)中に溶解した。EDC(4mg)を添加し、そして混合物を数秒間、勢いよく攪拌した。EDC 対 カルボン酸基のモル比は、0.5:1であった。澄んだ透明なヒドロゲルが3時間後に形成された。
b.ヒドラジド−HA(16mg)を、2ml Bis−Tris緩衝液(100mM、pH4.75)中に溶解した。EDC(32mg)を添加し、そして混合物を数秒間、勢いよく攪拌した。EDC 対 カルボン酸基のモル比は、4:1であった。澄んだ透明なヒドロゲルが1分後に形成された。
以前の実施例(13aおよびb)において記載される2つのヒドロゲルを、PBS(pH4.8)での48時間の反復洗浄により精製した。ヒツジ睾丸ヒアルロニダーゼ(PBS中の200u/ml、500μl)を各ヒドロゲルに添加し、そして37℃にてインキュベートした。4mgのEDCを使用して調製したヒドロゲル(実施例12a)は、4時間以内に完全に溶解された。第2のヒドロゲル(32mgEDCを使用して調製した、実施例12b)は26時間以内に完全に溶解された。
炭酸緩衝液(500μl、0.1M、pH9)中のFITC(0.5mg、1.25μモル)を、同じ緩衝液(2ml)中のヒドラジド−HA(20mg、M.W.2.5×105、10%のヒドラジド基)の溶液に添加した。反応を、暗所下、室温にて進行させた。1時間後、反応混合物を透析チューブ(M.W.カットオフ3500ダルトン)に移し、そして生成物が完全に未反応のFITCおよびその低分子量の副生成物を有しなくなるまで、暗所下で、PBS(pH7.4)に対して徹底的に透析した。透析物を凍結乾燥して生成物を黄色の固体として得た。FITC誘導体化ヒドラジド基の程度は、Akiraら(Carbohydrate Res.105:69−85,1982年)により記載される手順に従って決定され、そして約10%であることが見出された。上記の反応におけるヒドラジド基の誘導体化の程度は、FITC:ヒドラジド基の比率により制御される。例えば、FITCの量を2mg(5μモル)に増加すると、約40%の程度の誘導体化が得られ、一方4mg(10μモル)のFITCを使用すると、約60%の程度の誘導体化が得られる。
ヒドラジド−HA(20mg、M.W.2.5×105、10%のヒドラジド基)を、PBS(2ml、pH7.4)中に溶解した。次いで、PBS(257μl、1mM EDTAが補充される、pH7.4)中のbFGF(850μg)の溶液、続いてPBS(110μl、pH7.4)中の同種二官能性架橋剤PEGDA(9mg)の溶液を添加した。澄んだ混合物を数秒間攪拌した。透明なヒドロゲルが30分以内に形成された。bFGFは、ヒドロゲルを、室温で、100rpmにて、PBS(2ml、1%BSAおよび1mM EDTAが補充される、pH7.4)とともに攪拌することにより、放出した。放出媒体を、24時間毎に置き換え、そして回収したサンプル(各2ml)を測定まで−70℃にて保存した。回収されたサンプルそれぞれにおける放出されたbFGFの量を、R&D Systems(Minneapolis MN、USA、カタログ番号DY233)により供給される、bFGF ELISAキットを使用して、製造業者の指示に従って測定した。240時間の累積放出時間後に、取り込まれたbFGFの77.6%(660μg)が放出されたことが見出された。
