  Cytotoxicity of lapachol, β-lapachone and related synthetic 1,4-naphthoquinones against oesophageal cancer cells

  摘要：

  Naphthoquinones have been found to have a wide range of biological activities, including cytotoxicity to cancer cells. The secondary metabolites lapachol, alpha- and beta-lapachone and a series of 25 related synthetic 1,4-naphthoquinones were screened against the oesophageal cancer cell line (WHCO1). Most of the compounds exhibited enhanced cytotoxicity (IC50 1.6-11.7 mu M) compared to the current drug of choice cisplatin (IC50 = 16.5 mu M). This study also established that the two new synthetic halogenated compounds 12a and 16a (IC50 = 3.0 and 7.3 mu M) and the previously reported compound 11a (IC50 = 3.9 mu M), were non-toxic to NIH3T3 normal fibroblast cells. Cell death of oesophageal cancer cells by processes involving PARP cleavage caused by 11a was shown to be associated with elevated c-Jun levels, suggesting a role for this pathway in the mechanism of action of this cohort of naphthoquinone compounds.

  Oxidative free radical reactions between 2-benzyl-1,4-naphthoquinones and β-dicarbonyl compounds are described. Electrophilic carbon-centered radicals produced by the manganese(III) acetate or cerium(IV) ammonium nitrate oxidation of β-dicarbonyl compounds undergo efficient addition to a C–C double bond of quinone ring. This free radical reaction provides a novel method for the synthesis of naphthacene-5

  unoccupied molecular orbital reactivity of 2-substituted 1,4-naphthoquinones is possible to be reversed by deprotonation and application of the resulting dienolate as a 4π component in the higher-order [6 + 4]-cycloaddition proceeding in a completely pericyclic manner. 8,8-Dicyanoheptafulvene was shown to be an efficient 6π component in the developed reaction opening the access to functionalized cycloadducts

  这项研究表明，2-取代的1,4-萘醌的经典最低未占据分子轨道反应性可能会被去质子化并在更高阶的[6 + 4]-环加成反应中将得到的二烯酸酯作为4π组分应用而逆转。完全周转的方式。在已开发的反应中，显示8,8-二氰基七富烯是一种有效的6π组分，通过采用有机催化活化，以非对映选择性的方式打开了通往官能化环加合物的通道。还尝试引入已开发的高阶环加成的对映选择性形式。
