Outline of Research at the Start

本研究では、天然物 juglomycin C から juglorubin へと直接変換する一段階合成反応の基質一般性を検証すると同時に多くの誘導体を合成する。また、合成した誘導体の抗 C 型肝炎ウイルス活性を測定し、構造活性相関を明らかにする。また、金属イオンを juglorubin で挟んだサンドイッチ化合物を創製し、活性と機能を評価する。

Outline of Final Research Achievements

Juglorubin is a natural dye isolated from the culture of Streptomyces sp. 3094, 815, and GW4184. It has been previously synthesized via the biomimetic dimerization of juglomycin C, a plausible genetic precursor. In this study, the derivatives of juglorubin, 1-O-acetyljuglorubin dimethyl ester and juglorubin dimethyl ester, were found to exhibit antiviral activity against hepatitis C virus (HCV) without exerting any remarkable cytotoxicity against host Huh7 cells. They also inhibited liver X receptor activation and lipid droplet accumulation in Huh7 cells. These findings suggest that 1-O-acetyljuglorubin dimethyl ester and juglorubin dimethyl ester targeted the host factors required for HCV production.

Academic Significance and Societal Importance of the Research Achievements

本研究で、C型肝炎ウイルスの複製を阻害する誘導体を見出すことができた。非常に低濃度で抗ウイルス活性を発揮することや、宿主細胞には毒性が少ないことから、抗ウイルス剤としての実用化が期待できる。さらには抗ウイルス薬の開発で鍵となる作用機構を明らかにすることができた。
