mitogen-activated protein kinase kinase 7 (MKK7) are enzymes involved in intracellular signaling but can also contribute to tumorigenesis. We synthesized and characterized the biological activity of 1,4-naphthoquinones structurally similar to reported Cdc25 and(or) MKK7 inhibitors with anticancer activity. Compound 7 (3-[(1,4-dioxonaphthalen-2-yl)sulfanyl]propanoic acid) exhibited high binding affinity for
细胞分裂周期25(Cdc25)和有丝分裂原激活的蛋白激酶激酶7(MKK7)是参与细胞内信号传导的酶,但也可能有助于肿瘤发生。我们合成并表征了与报道的具有抗癌活性的Cdc25和/或MKK7抑制剂在结构上相似的1,4-萘醌的生物活性。化合物7(3-[((1,4-二氧萘并萘-2-基)硫烷基]丙酸)对MKK7的结合亲和力高(Kd = 230 nM),大于NSC 95397的亲和力(Kd = 1.1μM) 。尽管铅皮蛋黄素对MKK7的结合亲和力较低,但该化合物和含硫衍生物4和6-8是Cdc25A和Cdc25B的有效抑制剂。相对于MKK4和Cdc25 A / B,含有苯氨基侧链的衍生物22e具有选择性,而其异构体22f是Cdc25 A / B的选择性抑制剂。对几种萘醌的对接研究突出了有关分子取向和氢键相互作用的有趣方面,这可能有助于解释该化合物对MKK7和Cdc25B的活性。还筛选了最有效的基于萘醌的MKK7和/或Cdc25

Eleven 2,3-(substituted)-1,4-naphthoquinone derivatives were synthesized in yields ranging from 52-89%. These derivatives were evaluated for their cytotoxic effects on human lungs (H460), triple-negative breast (MDA-MB-231) and ovarian (A2780) cancer cell lines. Compounds 5f and 8 showed IC50 values of 3.048 x 10(-5) mol L-1 and 4.24 x 10(-6) mol L-1 for H460; 5c and 8 showed IC50 values of 2.16 x 10(-5) mol L-1 and 1.60 x 10(-5) mol L-1 for MDA-MB-231, and 5g and 8 showed IC50 values of 2.68 x 10(-6) mol L-1 and 3.89 x 10(-6) mol L-1 for A2780. Additionally, we conducted a docking study with the four most active compounds and the therapeutic targets PI3K and topoisomerase II showing the pharmacophoric conformation of these compounds.
Design, synthesis, and biological evaluation of novel naphthoquinone derivatives with CDC25 phosphatase inhibitory activity
CDC25 dual-specificity phosphatases are essential key regulators of eukaryotic cell cycle progression and the CDC25A and B isoforms are over-expressed in different tumors and related cancer cell lines. CDC25s are now considered to be interesting targets in the search for novel anticancer agents. We describe new compounds derived from vitamin K-3 that inhibit CDC25B activity with IC50 values in the low micromolar range. These naphthoquinone derivatives also display antiproliferative activity on HeLa cells as expected for CDC25 inhibitors and inhibit cell growth in a clonogenic assay at submicromolar concentrations. They increase inhibitory tyrosine 15 phosphorylation of CDK and induce the cleavage of PARP, a hallmark of apoptosis. (c) 2005 Elsevier Ltd. All rights reserved.

The concept of bioreductive alkylation as a mechanism of action of aziridinylquinoid anticancer agents has been investigated. The influence of quinone substituents on quinone reduction, on protonation of the aziridines prior to and following quinone reduction and on partitioning properties of the compound was examined. Parameters obtained from a combined electrochemical, chemical-stability and lipophilicity
