本発明のペプチドの選別
SARS-CoV-2のスパイクタンパク質(Spike protein、S protein)とアンジオテンシン変換酵素2(Angiotensin-converting enzyme2,ACE2)の結合を阻害するペプチドを開発するために、ペプチドライブラリからスクリーニングを介して6種のペプチドを選別した。選別されたペプチドの配列と分子量測定器を用いて測定したペプチドの分子量を下記表1に記載した。
本発明のペプチドのSARS-CoV-2スパイクタンパク質RBDに対する結合能の確認
本発明のペプチドがSARS-CoV-2の宿主細胞の侵入を遮断することができるのかを確認するため、先ず、SARS-CoV-2のスパイクタンパク質内のRBDを本発明のペプチドが認識して結合することができるのかを確認した。
本発明のペプチドのACE2-RBD結合阻害能の確認
本発明のペプチドがSARS-CoV-2の宿主細胞の侵入を遮断することができるのかを確認するため、本発明のペプチドが宿主細胞の膜タンパク質であるACE2とSARS-CoV-2のRBDとの結合を阻害するのかを確認した。
ヒト肺癌細胞における本発明のペプチドのACE2-RBD結合阻害能の確認
本発明のペプチドに哺乳動物細胞のコロナウイルス感染の予防、改善及び治療の能力があるのかを確認するため、ヒト肺癌細胞株にペプチドを処理した後、宿主細胞のACE2に対するSARS-CoV-2スパイクタンパク質RBDの結合能が減少するのかを確認した。
本発明のペプチドのSARS-CoV-2細胞感染抑制効果の確認
本発明のペプチドがSARS-CoV-2による細胞感染を抑制する効果があるのかを直接的に確認するため、Focus Reduction Neutralizing Test(FRNT)を行った。
ウイルス感染阻害率(%)=(対照群foci数 - 処理群foci数)/対照群foci数 × 100
