Abstract
基於生物等效性的概念,我們利用combretastatin A-4 (CA-4)為模版來合成兩類強效抗癌劑1-aroylindoles及1-aroylindolines,並且討論結構與活性的關係以及進行生物活性的評估。1-Aroylindoles是由不同取代的indoles與3,4,5-trimethoxybenzoic anhydride或 3,4,5-trimethoxybenzoyl chloride反應得到,而1-aroylindolines則是先將具有取代的indoles還原成indolines,再與3,4,5-trimethoxybenzoyl chloride或3,4,5-trimethoxy-2-nitrobenzoic acid反應得到。2-23的結構屬於1-aroylindoles,而25-30則屬於1-aroylindolines。
從抑制口腔上皮細胞癌KB細胞株生長的活性評估中得知,2、4、7、11、13、14、24及26的IC50濃度範圍在210-652 nM間,表現出中等抗癌活性,9、12及25的IC50分別為20 nM、8 nM以及87 nM,表現出強效抗癌活性,22的IC50為1.1 nM,比CA-4 (IC50為1.65 nM)的活性稍微增加,而最強效化合物23的IC50為0.16 nM,比CA-4強10倍。
結構與活性的關係資料顯示將C-5位置的methoxy以推電子基團如methyl (4)、5,6-methylenedioxy (7)、amino (11)或N,N-dimethylamino (12)來取代仍然保持強效抗癌活性。在1-aroylindole的C-2位置有methyl基團取代可增加活性。而在C-3位置有取代基則失去活性。藉由仿照AVE-8063及combretastatin A-4分別導入amino和hydroxyl官能基於1-aroylindole的C-4位置,架構出22和23,可得到最佳的抗癌活性。
