Abstract
槲皮素已被廣泛研究用於抗發炎、抗氧化、抗病毒及抗癌的特性,但槲皮素若要作為臨床使用,其最大的障礙在於水溶解性差,生物半衰期短,及口服生體可用率差,因此在本實驗希望開發微胞體系統包覆槲皮素進而提高藥品生體可用率及增加槲皮素的抗癌活性,另外希望藉由槲皮素抗氧化及抗癌的特性,能夠在合併Doxorubicin的治療下可達到更好的抗癌效果,且能夠減少Doxorubicin所產生的心肌傷害。

  本實驗以D-α-Tocopheryl polyethylene glycol 1000 succinate (TPGS)為主利用薄膜水合法開發出兩種微胞體系統來包覆槲皮素,第一種為槲皮素混合型微胞體,其最佳處方為槲皮素、Pluronic® L121和TPGS (6:40:10, w/w/w) 所組成的,第二種為槲皮素卵磷脂穩定化微胞體,其最佳處方為槲皮素、TPGS和卵磷脂 (6:40:80, w/w/w) 所組成的。

  所開發出的兩種最佳處方,混合性微胞體 (Quercetin:TPGS:L121=6:40:10, w/w/w) 及卵磷脂穩定化微胞體 (Quercetin:TPGS:Lecithin=6:40:80, w/w/w) 其物化特性如下,粒子大小分別為177.7±2.59 nm 及92.2±0.35 nm,藥物包覆率都約為99 %,藥物承載率分別為10.6 %和4.7 %,在細胞毒性實驗中對於三種人類乳癌細胞 MCF7,SKBR3和MDA-MB231及小鼠大腸癌細胞 CT26皆有明顯的抗癌活性。在動物實驗中,以最佳化的槲皮素卵磷脂穩定化微胞體 (Quercetin:TPGS:Lecithin=6:40:80, w/w/w) 對於小鼠體內CT26腫瘤抑制能力具有良好的效果,且在大鼠藥物動力學實驗中證實槲皮素卵磷脂穩定化微胞體在靜脈給予後,相對生體可用率提升了177 %,而口服相對生體可用率及絕對生體可用率分別增加了412 %和2.12 %,進一步將槲皮素卵磷脂穩定化微胞體合併Doxorubicin治療小鼠腫瘤,結果顯示合併治療能降低Doxorubicin對於心肌細胞的傷害,且比較起單獨使用Doxorubicin有更好的腫瘤抑制效果。
