Outline of Final Research Achievements

The purpose of this study is to develop compounds that enhance the anti herpes simplex virus (HSV) effects of acyclovir by controlling phosphorylation enzyme of acyclovir, etc., through a combination of isolation of active constituents from natural plants, synthesis of active compounds, and chemoinformatics studies. We have successfully developed a predictive model for anti-HSV-1 activity of triterpenes. Some triterpene glycosides showed the effects in enhancing the anti-HSV-1 activity of acyclovir in combination with acyclovir. In addition, piperine isolated from Piper nigrum belonging to the genus Piper and piperine derivatives with an amide moiety increased the number of plaques, suggesting that they activate HSV-1.

Academic Significance and Societal Importance of the Research Achievements

本研究において、トリテルペン類の抗単純ヘルペスウイルス(HSV)活性の判別モデルを作成するとともに、トリテルペン配糖体がアシクロビルとの併用により、アシクロビルの抗単純ヘルペスウイルス(抗HSV-1)作用を増強させる効果があることを見出した。さらに、コショウなどのコショウ属植物に含有する辛味成分piperineがHSV-1を活性化させる可能性があることを見出した。本研究成果は、アシクロビルの副作用軽減薬の開発に貢献でき、社会的な意義があると同時に学術的にも意義がある。
