Outline of Final Research Achievements

Chb-M', alkylating agent-conjugated consensus sequence binding compound (alkylating agent-conjugated pyrrole-imidazole polyamide) disturbed cell growth of various types of glioma cell lines. Its main mechanism was apoptosis induction. Using mRNA array and phosphorylated protein array, a group of genes controlled by Chb-M 'administration was identified, which showed the inhibition of cell survival signal transduction. These results suggest that Chb-M 'targeting abnormal transcription network may become a drug for treatment of glioma.

Academic Significance and Societal Importance of the Research Achievements

悪性グリオーマは、予後不良の悪性脳腫瘍である。グリオーマ悪性転化に関わるメカニズムを標的にした薬剤の開発を行った。コンセンサス配列結合阻害化合物Chb-M’が、複数のタイプのグリオーマ細胞株でアポトーシス誘導を行い、腫瘍増殖抑制を示した。これらの結果から、Chb-M’がグリオーマ治療薬として有望であることが明らかとなった。
