Outline of Final Research Achievements

Designed and synthesized aplyronine A-swinholide A hybrid, which consists of the macrolactone of aplyronine A and the side chain of swinholide A. This Hybrid retained strong cytotoxicity and actin-depolymerizing activity. In addition, hybrid induces PPI between actin and tubulin in the manner of aplyronine A. Furthermore, I conducted the structure-activity relationships about amino acid moiety by using hybrid. The trimethylserine ester group was important for potent cytotoxicity. Also, comparing the side chain analogs of aplyronine A and swinholide A, we clarified the side chain analog of aplyronine A was stronger actin-depolymerizing activity.

Academic Significance and Societal Importance of the Research Achievements

ガンは日本人の死因第一位であり、その治療法が求められる。アプリロニンAは新規作用機序を持つ抗腫瘍活性物質であるが、天然からの供給、誘導化に制限があるため研究展開が困難である。そこで本研究では、他の天然物とのハイブリッドアナログを設計・合成し、アプリロニンAと同様の作用機序を有する構造簡略型ハイブリッドアナログの創出に成功した。本化合物は供給・誘導の制限を緩和し、今後の研究展開が期待できる。
