とを有効成分として含有する角膜障害治療剤に関する発明である。
本発明に用いられるSSSR類似体の代表的な製造例を以下に示す。
ペプチド自動合成機430A(Applied Biosystems社製)を用い、既設ソフトに従って第3ブチルオキシカルボニル(BOC)法により保護ペプチド樹脂を合成した。出発原料として4-(オキシメチル)フェニルアセトアミドメチル[Boc-Arg(Tos) PAM]樹脂担体 (0.5mmolスケール)を使用した。本合成法では、Na-アミノ保護基であるBoc基の除去には30%トリフルオロ酢酸(TFA)/ジクロロメタン、70%TFA/ジクロロメタンを使用し、その洗浄にはN-メチル-2-ピロリドン(NMP)/ジクロロメタンを用いた。縮合剤のN,N’-ジシクロへキシルカルボジイミド(DCC)及び1-ヒドロキシベンゾトリアゾール(HOBt)とN-保護アミノ酸のBoc-Ser(OBzl)誘導体はそれぞれアミノ基に対し4当量用い、反応溶媒としてジメチルスルホキシド(DMSO)−NMP (8:2)を使用した。縮合反応終了後、残存するアミノ基を完全に塞ぐ操作として無水酢酸/N,N-ジイソプロピルエチルアミン(DIEA)にて欠陥ペプチドの生成を防いだ。Boc基の除去と、Boc-Ser(OBzl)の縮合を繰り返し最終保護ペプチドの構築を行った。得られた保護ペプチド樹脂からのペプチドの切り出しと全ての保護基の脱離は無水フッ化水素(HF)処理(HF:pークレゾール、8:2(V/V)、−2〜−5℃、60分)によって行った。反応後、HFを留去し、0.1%トリフルオロ酢酸水にてペプチドを抽出し、粗生成物を凍結乾燥粉末として得たのち、分取精製に供した。分取精製は島津製作所製HPLC LC8A(カラム:YMC製ODS 30 X 240mm)を使用し、アセトニトリル/水系(0.1%TFA含有)で0.5−2%のグラジエント(80分)で行った。得られた目的物の高純度画分を集め、アセトニトリル留去後、凍結乾燥して標的化合物のTFA塩70mg(収率32%)を得た。

(1)角膜上皮伸展に対する作用(in vitro)
雄性日本白色ウサギの角膜を用い、Nishida らの方法(J. Cell Biol., 97, 1653-1657 (1983))に準じ、角膜片の組織培養系での角膜上皮伸展長を指標にして角膜上皮伸展に対する影響を検討した。
ウサギ角膜片より切り出した角膜ブロック(1群6個)を、被験化合物を含む培養液(TC−199)中、37℃・5%CO2の条件下で24時間培養した。培養後、角膜ブロックをエタノール−氷酢酸(容積比95:5)混合液中で固定し、パラフィンで包埋して切片を作製した。切片を脱パラフィンした後、ヘマトキシリン−エオジン染色し、顕微鏡下で上皮細胞層の伸展長を測定した。
実験に用いたペプチドの代表例を表1に示す。
表1に示すように、SSSR類似体単独、サブスタンスP単独およびFGLM単独では角膜上皮の伸展に対する影響は認められなかったが、SSSR類似体とサブスタンスP(若しくはFGLM)の両方を含む培養液で培養をすると、角膜上皮の著しい伸展促進が認められた。
皮膚創傷治癒効果は以下に示す方法で試験することができる。
