摘要:

以烟草中含量丰富的大环二萜类化合物2,7,11-西柏三烯-4,6-二醇(CBT)为母体, 其C6位羟基经酯化/醚化, 合成了28个西柏三烯-4-醇-6-羧酸酯及西柏三烯-4-醇-6-烷氧类化合物. 采用核磁共振波谱(NMR)和高分辨质谱(HRMS)对目标化合物进行了结构表征, 并初步评价了其生物活性. 细胞毒活性测试结果表明, 部分化合物对肿瘤细胞的抑制作用与阳性对照顺铂相当, 其中α-2,7,11-西柏三烯-4-醇-6-O-苯乙酸酯(1i)对乳腺癌细胞株MCF-7的IC50值为15.45 μmol/L, α-2,7,11-西柏三烯-4-醇-6-O-(2-氟)苯乙酸酯(1t)对肺癌细胞株SMMC-7721的IC50值为11.44 μmol/L.

Abstract:

Twenty eight α-2,7,11-cembratriene-4,6-diol derivatives were prepared by the modification at C6 position via introduction of acyl and ether groups. Their structures were confirmed by nuclear magnetic resonance spectroscopy(NMR) and high resolution mass spectrometry(HRMS). The synthesized compounds were screened for their in vitro biological activity. The results of 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfopheny)-2H-tetrazolium(MTS) assay indicated that some of them showed the same anticancer activity as cisplatin(DDP) did. Among them, α-2,7,11-cembratriene-4-ol-6-phenylacetate(1i) showed cytotoxicity against MCF-7 with an IC50 value of 15.45 μmol/L, and α-2,7,11-cembratriene-4-ol-6-(2-F)phenylacetate(1t) showed cytotoxicity against SMMC-7721 with an IC50 value of 11.44 μmol/L, respectively. Structure-activity relationship revealed that the phenylacetate substituents at C6 position played an important role in inhibition activity.

Key words: Cembratriene derivative, Antitumor, Tobacco
