代谢
三种1,4-萘醌(NQs)的暴露降低了两种细胞类型中的细胞内谷胱甘肽平。对于BF-2和HepG2细胞,用谷胱甘肽耗竭剂丁硫氨酸亚砜胺(BSO)预处理,增强了5,8-羟基-1,4-NQ和二氯苯的细胞毒性;用DT-二嘧啶酶的抑制剂黄酮预处理对这些两种NQs的毒性没有影响。显然,对于这两种醌类化合物,BF-2和HepG2细胞中的主要代谢途径涉及通过单电子还原反应的化还原循环,产生消耗细胞内谷胱甘肽的活性中间体。用BSO预处理BF-2细胞,而不是用二黄酮预处理,增强了1,4-NQ的毒性,这再次表明代谢是通过单电子还原发生的。然而,对于HepG2细胞,用二黄酮预处理,而不是用BSO预处理,增强了1,4-NQ的细胞毒性。显然,与BF-2细胞相比,HepG2细胞中的1,4-NQ是通过涉及双电子还原的DT-二嘧啶酶代谢的。
Exposures to the three 1,4-naphthoquinone (NQs) reduced intracellular glutathione levels in both cell types. For the BF-2 and HepG2 cells, pretreatments with buthionine sulfoximine (BSO), a glutathione-depleting agent, potentiated the cytotoxicity of 5,8-hydroxy-1,4-NQ and dichlone; pretreatment with dicoumarol, an inhibitor of DT-diaphorase, had no effect on toxicity of these two NQs. Apparently, for these two quinones the predominant metabolic pathway in both the BF-2 and HepG2 cells involved redox cycling via a one-electron reduction reaction, generating reactive oxygen intermediates that consumed intracellular glutathione. Pretreatment of the BF-2 cells with BSO, but not with dicoumarol, potentiated the toxicity of 1,4-NQ, again indicating that metabolism occurred via one electron reduction. However, for the HepG2 cells, pretreatment with dicoumarol, but not with BSO, potentiated the cytotoxicity of 1,4-NQ. Apparently, in the HepG2, as compared to the BF-2, cells, 1,4-NQ was metabolized by DT-diaphorase in a reaction involving a two electron reduction.

    日期:2011.7.20
    Benzonaphthofurandiones containing four coplanar fused aromatic rings were synthesized and evaluated for their cytotoxicity against five human cancer cell lines, and their inhibitory activity on topoisomerases. These benzonaphthofurandiones were prepared by condensation of 2,3-dichloronaphthoquinone and three aromatic diols with base catalysts in alcohol. The synthesized compounds were o-alkylated with six dialkylaminoalkyl halides. The hydroxy derivatives (8a-8g) exhibited relatively potent cytotoxicity among the prepared compounds. These compounds were evaluated as excellent inhibitors against topoisomerase II (topo II). Especially, the hydroxy analogue with branched methyl side chain (8e) showed high cytotoxicity against cancer cell lines and good inhibitory activity on topo II.
