  New cytotoxic diterpenylnaphthohydroquinone derivatives obtained from a natural diterpenoid

  摘要：

  Diterpenylquinone/hydroquinone derivatives were prepared through Diels-Alder cycloaddition between natural myrcecommunic acid or its methyl ester and p-benzoquinone (p-BQ), using BF3 center dot Et2O as catalyst or under microwave (Mw) irradiation. Acetyl, methyl and benzyl derivatives of several diterpenyinaplithohydroquinone were prepared from cycloadducts following two basic synthetic strategies, either protection before aromatisation or viceversa. Some of them were further functionalised at the B-ring of the decaline core. Most of the new compounds were evaluated and some of them resulted cytotoxic against several tumour cell lines with IC50 values tinder the mu M level. (c) 2007 Elsevier Ltd. All rights reserved.

  through induction of biomimetic breaks and rearrangements of the diterpene skeleton. All the isomers generated were completely characterized by spectroscopic procedures. The resulting compounds have been tested in vitro on cultured cancer cells, showing their relevant antineoplastic cytotoxicity, with GI50 values in the μM and sub-μM range. The rearranged compound 8 showed the best cytotoxic results

  萜烯醌是自然界中广泛存在的混合生物发生初级或次级代谢物，具有许多生物活性，包括抗肿瘤细胞毒性，激发了这项工作。在这里，我们提出了几种二萜氢醌 (DTHQ) 衍生物的细胞毒性结构-活性关系，这些衍生物是从用作起始材料的天然拉丹二萜类 myrceocommunic 酸中获得的。通过环氧化、臭氧分解或脱羧，以及通过诱导二萜骨架的仿生断裂和重排，在双环核心上实施了不同的结构修饰，改变了十氢化萘的功能和立体化学。所有产生的异构体都通过光谱程序完全表征。所得化合物已在体外培养的癌细胞上进行了测试，显示其相关的抗肿瘤细胞毒性，GI50 值在 μM 和亚 μM 范围内。重排的化合物 8 显示出最好的细胞毒性结果，GI50 在亚微摩尔范围内，保留了母体化合物的细胞毒性水平。在这份报告中，证明了拉丹烷骨架在化学转化方面的多功能性以及继续使用结构修饰来获得新的生物活性化合物的兴趣。
