生理活性物質及び水から構成される混合物を凍結乾燥して、生理活性物質を製造する製造方法であり、生理活性物質が酵素、組み換えタンパク質、抗体、ペプチド又はアミノ酸である点を要旨とする。
−NHCOR1 (1)
R1はメチルを表す。
したがって、本発明の保護剤は、生理活性物質{酵素、組み換えタンパク質、抗体、ペプチド、アミノ酸、核酸、糖、抗生物質及びビタミン等}を用いる分野{各種研究開発、診断・検査薬や医薬品等}において、極めて有用である。
なお、生理活性(力価)とは、生理活性物質の純度を意味する。
水性溶媒としては、緩衝液{リン酸緩衝液、酢酸緩衝液、クエン酸緩衝液及び硼酸緩衝液等}及び水混和性有機溶剤{メタノール、エタノール、2−プロパノール、ブタノール、エチレングリコール、グリセリン、ジメチルスルホキシド及びジメチルホルムアミド等}等が挙げられる。

水及び/又は水性溶媒を含む場合、α位のアミノ基が変性されたアミノ酸エステル又はα位のアミノ基が変性されたアミノ酸アミドの含有量(重量%)は、α位のアミノ基が変性されたアミノ酸エステル又はα位のアミノ基が変性されたアミノ酸アミドと、水及び/又は水性溶媒との合計重量に基づいて、0.01〜20が好ましく、さらに好ましくは0.1〜10である。
N−α−アセチルアルギニン{アルギニンアセトアミド、株式会社エムピーバイオジャパン}12.6部(0.05モル部)、メタンスルホン酸1部及びエタノール92部(2モル部)を均一混合し、80℃で5時間加熱攪拌し、エバポレーターで濃縮後、水から再結晶し、減圧乾燥{60℃、20Pa}して、本発明の凍結乾燥用保護剤(1){N−α−アセチルアルギニンエチルエステル}を得た。
N−ベンゾイル−アルギニンエチルエステル{株式会社エムピーバイオジャパン}をそのまま、参考用の凍結乾燥用保護剤(2)とした。
リゾチーム{和光純薬工業株式会社、力価20,000units/mg}50mgをイオン交換水10gに溶解させた後、これに、実施例1で得た凍結乾燥用保護剤(1)32.3mg(0.13ミリモル)を加えて均一混合して、凍結乾燥用水溶液を調製した。この水溶液を容積20mLの密栓付きガラス瓶に移し、ガラス瓶ごと液体窒素中に1分浸漬させて凍結させた後、ガラス瓶を凍結乾燥機{アルバック株式会社製DF−01H}内に移し、減圧下(13.3Pa)、−40℃で40時間かけて凍結乾燥して、乾燥体を得た。引き続き、乾燥体は、五酸化リンが入ったデシケーター内で3日間保存して、凍結乾燥リゾチーム(R1)を得た。
「凍結乾燥用保護剤(1)32.3mg(0.13ミリモル)」を、「凍結乾燥用保護剤(2)40.5mg(0.13ミリモル)」に変更したこと以外、実施例2と同様にして、凍結乾燥リゾチーム(R2)を得た。

6ヶ月保存後の酵素活性の保持率(%)=(ΔB’/ΔBb)×100
酵素等の力価が低下する主な原因としては、酵素等の3次元構造が凍結乾燥により歪むことが考えられる。しかし、本発明の凍結乾燥用保護剤を用いて凍結乾燥すると、この歪みを大幅に抑えることができたと考えられる。
