Abstract
癌症是全球死亡的主要原因之一,佔所有死亡人數的13%,無庸置疑的,抗腫瘤藥物是最大的市場需求。雖然,近年對於癌症的治療已有長足的進步,但傳統的癌症藥物因高毒性、產生耐藥性、對癌細胞專一性不佳的問題及使用有機溶劑溶解難溶性藥物導致病患發生過敏,產生許多不良的副作用,因此,需藉由先進的藥物傳輸系統搭配,提高藥物包覆率,改善大多數抗癌藥物的低水溶解度問題,將藥物輸送到癌細胞,提高進入癌細胞的劑量,增強治療效能,降低副作用及抗藥性的產生等。迄今已有數種以奈米微膠粒為載體的產品進入臨床試驗及被美國食品藥物管理署(FDA)核准上市,顯示奈米微膠體藥物傳輸劑型具備極高的發展潛力,因此本研究是以奈米微膠體來建立藥物傳輸系統技術平台為首要重點。研究一為利用磷脂質穩定奈米微膠體承載難溶性抗癌藥物-多西他賽,此藥物傳輸系統的特點除了保有微膠體擁有的優點之外,進而改善被包埋藥物很容易由微膠體漏出來的缺點,同時增加難溶性藥物包埋於微膠體的安定性,也提高微膠體的藥物承載量,並於動物實驗中證實此藥物劑型和以吐溫80和酒精作為助溶劑的市售品鈦能相比有更好的藥物治療效果及安全性。研究二為利用雙功能抗體(抗聚乙二醇及抗人類上皮因子接受體第2蛋白因子(HER2)以非共價鍵結合於承載多西他賽之磷脂質穩定奈米微膠體,作為標靶性藥物載體,探討有無抗體之奈米載體被細胞吞噬之能力,追蹤細胞吞噬載體之路徑,而於小鼠異種移植乳癌腫瘤模式進行治療,在有抗體鍵結之標靶性之奈米載體其抑制腫瘤生長的效果相當明顯(p<0.05)。此磷脂質穩定奈米微膠體藥物傳輸系統研究結果將可提供重要資訊應用於未來難溶性藥物輸送及標靶性癌症治療。
