Outline of Final Research Achievements

In this study, we designed and synthesized C5-desoxy analogs of THIQ alkaloids as hitherto unexplored structural variants for the evaluation of their DNA alkylating activities. The C5-desoxy analog exhibited greater DNA alkylating ability with a wider tolerance for sequence variations compared to the commercially available cyanosafracin B. These results clearly indicated that the oxygen-containing functional group at the C5 position is not essential for the DNA alkylation. Rather, the C5-desoxy analogs are capable of facilitating covalent adduct formation with DNA. The substantial influence of the C5-desoxy A-ring having the C8 phenolic hydroxyl group, as well as a C1 substituent in the vicinity of the C21 aminonitrile was also demonstrated.

Academic Significance and Societal Importance of the Research Achievements

本研究では、複雑な五環性骨格を一挙に構築する酵素合成と官能基を自在に変換する有機合成を融合させ、抗腫瘍性抗生物質サフラマイシン類の類縁体を簡便かつ迅速に合成した。この化学-酵素ハイブリッド合成によって初めて創出が可能となった化合物群の中から、実際に天然物シアノサフラシンよりも優れたDNAアルキル化能(共有結合形成能力)を有する創薬候補分子群を見出すことができた。更に、合成アナログ群の構造とDNAアルキル化能との相関を調査し、中分子アルカロイドと核酸との共有結合複合体を活用して核内タンパク質の機能を制御する萌芽的な研究を開拓することができた。
