Abstract
神經膠質瘤在原發性腦瘤中最為常見,其中有三分之二屬惡性。美國每年約有17,000 名被診斷出患有原發性腦瘤,而神經膠質瘤就佔 60 %。根據世界衛生組織分類為高惡性度屬於第三級退化性星狀細胞 (anaplastic astrocytoma, AA) 及第四級多型性神經膠質母細胞瘤 (glioblastoma multiforme, GBM) 最為普遍。腦瘤治療通常以手術切除為主,輔以化學及放射線治療。但腦瘤治療的預後不佳,特別是化學及放射線治療會產生游離自由基,不僅會殺死癌細胞,連正常細胞也會殺死。最近有研究指出,抗氧化劑能提高治療效果、降低副作用並保護正常細胞。天然植物資源豐富種類繁多,據科學證實其具保健並防止癌症在復發之潛力,且多酚具有預防癌症之效果。
本研究共採集 60 種天然植物資源製備成冷凍乾燥甲醇取物,利用人類神經膠質腦瘤細胞屬於第三級的 U-87 MG 與第四期的 GBM 8401 以 MTT 還原能力法來評估萃取物對於神經膠質瘤細胞抑制生長之作用進行篩選。其中以 YY-02 甲醇萃取物抑制率最高,接著再以不同極性之溶劑正己烷、乙酸乙酯、丙酮及甲醇依序進行分離萃取,再評估其總多酚及類黃酮之含量、抗氧化及抗脂質過氧化能力,結果以甲醇再分離萃取的效果最好,並且對此兩種人類惡化神經膠質瘤細胞均具有抑制效果並具有濃度依存性,另由細胞形態及細胞週期分析結果亦發現 YY-02 甲醇分離萃取物之抗腫瘤機制乃經由細胞凋亡之模式造成神經膠質瘤細胞死亡,因此 YY-02 將來可能成為一具有開發潛力的藥物以做為治療神經膠質瘤之新應用。
