Outline of Research at the Start |
現在、B型肝炎ウイルス(HBV)に対する治療選択は核酸アナログとインターフェロン(IFN)に限定される。現在の新規薬剤開発のボトルネックは、適切なHBV感染培養系と簡便な大規模スクリーニング系の開発が十分でない事が一因となる。本研究では申請者らが明らかにしたHBVタンパクによるIFNシグナル阻害に着目した新規の抗HBV薬のレポーターアッセイを用いた大規模スクリーニング系を構築。同スクリーニング系を用いた検討にて複数の新規薬剤候補を同定可能であった。今研究では同スクリーニング系を用いて、更なる新規の抗HBV薬の同定、既存薬のrepositioning を目指す。

Outline of Final Research Achievements |
We revealed that hepatitis B virus X protein inhibit IFN signaling pathway. We focused on these mechanisms, we established novel high-throughput screening system to find novel anti-HBV drug by using reporter assay system. In addition, we utilized “Hokdai library” which consisted of chemical library and existing drugs e.g. By using this novel system and drug library, we found several potential compounds which could suppress HBV replications.

Academic Significance and Societal Importance of the Research Achievements |
B型肝炎ウイルス(HBV)は全世界で4億人の感染者が存在し、世界的な公衆衛生上の問題となる感染症である。一方で、現時点までに使用可能な抗HBV薬は核酸アナログとIFNのみであり、加えてこれらの薬剤ではHBVの排除は困難で、更なる抗HBV薬の開発は急務である。我々は、独自に開発したスクリーニング系と北海道大学が独自に有する薬剤、化合物を用いて複数の抗HBV薬候補を同定した。これらの薬剤は、既存薬と比してHBs抗原の低下効果が強く、臨床的治癒となるHBs抗原の消失が期待される薬剤候補であった。これらの、新規薬剤候補の臨床応用を目指す事によりHBV撲滅に向けた創薬基盤の萌芽となりうる。
