摘要


DC-81是屬於比咯苯偶氮駢(PBDs)這類化合物,是一種由鏈黴菌所產生的抗癌抗生素,它可以抑制核酸的合成和阻斷DNA的轉錄。PBDs具有選擇性的鍵結在DNA的次溝槽,是藉由中心B環上的C11位置和鳥糞嘌呤上N2形成一共價鍵結的複合物,而達到其抗癌的效果。 最近,我們發表了一個簡短而且可以大量合成PBD的合成途徑。而本論文主要是嘗試延伸我們的研究,在PBD的C環上導入一個含氧官能基。根據生物活性測試結果顯示,這類PBD的藥物擁有相當高的抗腫瘤細胞活性。

並列摘要


DC-81 , an antitumor antibiotic produced by streptomyces species, belogs to the pyrrolo[2,1-c][1,4]benzodiazepines (PBDs) which are potent inhibitors of nucleic acid synthesis and block DNA transcription. They bind selectively in the minor groove of DNA forming a covalent aminal bond between the C11 position of the central B-ring and the N2 amino group of a guanine base. This adduct formation is thought to lead to the observed biological activity. Recently, we reported a very short route and large scale synthesis of PBD. In this dissertation, we extended our studies to oxygen group incorporated at C-ring of PBD. Biological test showed that these drugs have highly anticancer activity.
