Outline of Final Research Achievements

The marine alkaloids lamellarins displays high anticancer activity by inhibiting both nuclear and mitochondrial topoisomerase I, however, they are equally toxic to normal cell lines. TPP cation is known to accumulate in mitochondria in preference to mitochondria of tumor cells compared with nontumor cells. We aimed to create novel mitochondria-targeting agents by incorporating TPP cation in the structure of lamellarin. We established a novel synthetic route to 1-dearyl lamellarin, which is applicable for synthesis of lamellarin itself. By this method the lamellarin alcohol was synthesized and the TPP cation moiety is tethered to the C-1 position of lamellarin through a valerate linker. The ester-linked compound is designed to be hydrolyzed under physiological condition and liberate active lamellarin alcohol after passing through mitochondrial inner membrane. The TPP-lamellarin thus synthesized showed 3-fold higher cytotocicity against HeLa cells than the parental lamellarin alcohol.

Academic Significance and Societal Importance of the Research Achievements

抗がん活性化合物にTPPカチオンを結合させることによるがん細胞選択性の増大効果は既に複数例報告されているが,本研究により導入効果の実証例がさらに増えた。がん細胞に集積するリガンドを利用する原理は,広く他の抗がん活性物質への応用にも期待できる。ラメラリンの合成法は多く知られているが,パラジウムなどの高価なレアメタル触媒を用いた反応を基盤としたものが殆どである。本研究の結果,Paal-Knorr反応を利用した簡便で効率的なラメラリンの新規合成方法が確立された。
