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
ML162 derivatives incorporating a naphthoquinone unit as ferroptosis/apoptosis inducers: Design, synthesis, anti-cancer activity, and drug-resistance reversal evaluation
obtaining more active anticancer agents via the ferroptosis and apoptosis dual cell death processes. Of these compounds, was identified as the most active one that exhibited promising anticanceractivity both in vitro and in vivo viaferroptosis and apoptosis dual-targeting processes, without obvious toxicity compared with ML162. On one hand, could trigger ferroptosis in cells by inducing intracellular lipid
