A new benzoquinone-type retro-dihydrochalcone, named evelynin, was isolated from the roots and rhizomes of Tacca chantrieri. The structure was elucidated on the basis of the analysis of spectroscopic data and confirmed by a simple one-step total synthesis. Evelynin exhibited cytotoxicity against four human cancer cell lines, MDA-MB-435 melanoma, MDA-MB-231 breast, PC-3 prostate, and HeLa cervical carcinoma cells, with IC(50) values of 4.1, 3.9, 4.7, and 6.3 μM, respectively.
一种新型苯醌型反式二氢查耳酮,命名为埃夫林宁,从紫箕的根和根茎中分离得到。该结构是基于光谱数据分析确定的,并通过简单的一步全合成得到证实。埃夫林宁对四种人癌细胞系 MDA-MB-435 黑色素瘤、MDA-MB-231 乳腺癌、PC-3 前列腺癌和 HeLa 宫颈癌具有细胞毒性,IC50 值分别为 4.1、3.9、4.7 和 6.3 μM。
