A new enynyl-benzenoid, antrocamphin O (1,4,7-dimethoxy-5-methyl-6-(3′-methylbut-3-en-1-ynyl)benzo[d][1,3]dioxide), and the known benzenoids antrocamphin A and 7-dimethoxy-5-methyl-1,3-benzodioxole, were isolated from the fruiting bodies of Antrodia camphorata (Taiwanofungus camphoratus). The structure of antrocamphin O was unambiguously assigned by the analysis of spectral data (including 1D and 2D NMR, high-resolution MS, IR, and UV) and total synthesis. Compound 1 was prepared through the Sonogashira reaction of 5-iodo-4,7-dimethoxy-6-methylbenzene and 2-methylbut-1-en-3-yne as the key step. The benzenoids were tested for cytotoxicity against the HT29, HTC15, DLD-1, and COLO 205 colon cancer cell lines, and activities are reported herein.
从台湾乳菇(Antrodia camphorata,台湾真菌)的子实体中分离得到一种新的烯炔基苯并二氧戊环类化合物antroca mphin O(1,4,7-二甲氧基-5-甲基-6-(3'-甲基丁-3-烯炔基)苯并[d][1,3]二氧戊环)和已知的苯并二氧戊环类化合物antrocamphinA 和 7-二甲氧基-5-甲基-1,3-苯并二氧戊环。通过光谱数据(包括一维和二维核磁共振波谱、高分辨质谱、红外和紫外光谱)分析和全合成明确指认了antrocamphin O的结构。化合物1的关键步骤是通过Sonogashira反应制备,即以5-碘-4,7-二甲氧基-6-甲基苯和2-甲基丁-1-烯-3-炔作为原料。本研究所分离的苯并二氧戊环类化合物被用于检测其对人结肠癌HT29、HTC15、DLD-1、和COLO 205细胞株的细胞毒活性,并报道了其活性。
