Outline of Research at the Start

SARS-CoV-2感染の収束が掴めない現状において、現行の他疾患既承認薬治療法に代わる切り札として、特異標的薬が切望されるが、ウイルス複製および阻害剤作用の各機序に関して未だ明らかでない点も多く、薬剤開発とウイルス性状解析の同時展開が強いられる。そこで本研究は、抗HIV薬研究開発の実績を最大限に転用することで、SARS-CoV-2特異標的薬開発を効率的に進めることを目指す。

Outline of Annual Research Achievements

本研究課題「抗HIV薬研究を起点とする新規SARS-CoV-2治療戦略探索とウイルス性状解析」は、(A) 網羅的抗HIV阻害剤ライブラリーを起点に5戦略薬剤探索によりSARS-CoV-2特異標的シーズを見出すと共に、それらをプローブとした (B) 包括的ウイルス学的解析により、新規SARS-CoV-2治療法に繋がる基盤データを取得することを主目的とする。本年度も引き続き、5戦略薬剤探索の中から、SARS-CoV-1およびSARS-CoV-2に対して、これまでに有意な抗ウイルス活性が報告された、(1) 融合阻害剤群および (3) プロテアーゼ阻害剤群に関して、所属機関で分離した各種SARS-CoV-2 臨床分離株を、アフリカミドリザル腎臓上皮細胞由来VeroE6/TMPRSS2株またはヒト肺上皮細胞由来Calu-3株などの標的細胞に感染させ、細胞変性効果(CPE)およびウイルスRNA量測定などによる従来の抗ウイルス評価を進めることができた。さらに、昨年度構築した新規セルベースアッセイを用いた候補化合物の評価も展開することができた。その結果、いくつかの有用候補化合物を見出すことができ、現在は、それらを基盤として、包括的なウイルス学的解析を開始し、新規治療法に繋がる基盤データの取得を試みている。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

本研究課題の主要研究である5戦略薬剤探索に関しては、上記「研究実績の概要」で示した通り、おおむね順調に進行し、いくつかの候補化合物を見出すことができた。

Strategy for Future Research Activity

研究実施計画でも示したが、見出した有用候補化合物をプローブとして、包括的なウイルス学的解析を開始し、新規治療法に繋がる基盤データの取得を試みる。
