Abstract
一般細胞透過過度增生、產生功能異常等一系列變化後,發展成癌症。而癌症本身具有不少治療的方式,其中以多標靶藥物治療的方針是近年來研究發展的一個著重方向,而對多標靶藥物的設計也是作為本論文發展的核心概念。
本論文透過以單胺氧化酶(MAO)和離胺酸特異性組蛋白去甲基酶1(LSD1)作為多標靶的目標,並參考過去已發表的文獻及實驗室之前成功的路徑,作為設計合成小分子抑制劑的方向,合成了一系列以多種雜環為主體的化合物,有21-24、37-40、 44-46和49-50,並在後續交由合作的實驗室進行了生物活性試驗,以對前列腺癌細胞、乳癌和大腸直腸癌細胞的半數生長抑制濃度(GI50, μM)作為實驗結果的探討。
在合成的一系列化合物(21-24, 37-40, 44-46和49-50)是以多種雜環為主體,並探討它們與tranylcypromine (TCPA)在不同取代位置上的結合,透過結構與活性的關係加以修飾,其中,以indoline和indole作為主體,並取代於7號位上的24和40在對前列腺癌細胞(PC-3)、乳癌細胞(MDA-MB231)和大腸直腸癌細胞(HCT116)的半數生長抑制濃度(GI50, μM)試驗中具有較佳的活性。至於以quinoline為主體的44-46和49-50會在後續在進行活性試驗及探討,希望藉此找出具有最佳活性的雜環主體,以及其在取代位置上的選擇,而達到結構與活性最佳化的目標。
