    摘要:
    几十年来,Tau 蛋白一直被描述为促进微管蛋白组装成微管的因子。Tau 蛋白表达的失调或改变与多种脑癌有关,包括侵袭性和致死性极强的多形性胶质母细胞瘤(GBM)。因此,Tau 很有希望成为开发新型疗法的靶点。在这里,我们研究了17种新系列的2-氨基噻唑与类黄酮融合的杂化化合物(TZF)在Tau结合、Tau纤维化以及对表达Tau的癌细胞的细胞效应方面的结构-活性关系。通过光谱荧光测定法,我们发现 2 和 9 这两种化合物与 Tau 的亲和力很高,并表现出强烈的抑制 Tau 纤维化的倾向。随后,我们对这些化合物在几种来自胶质母细胞瘤的 Tau 表达细胞上的生物活性进行了评估。这两种先导化合物对细胞具有很高的抗代谢活性,这与线粒体网络裂变增加有关。此外,我们还发现这两种化合物都能诱导新形成的神经元样突起内的微管成束,并使细胞迁移发生缺陷。综上所述,我们的研究结果为开发针对 Tau 表达癌细胞(如脑胶质瘤)的新型强效分子提供了坚实的实验基础。

    Tau protein has been described for several decades as a promoter of tubulin assembly into microtubules. Dysregulation or alterations in Tau expression have been related to various brain cancers, including the highly aggressive and lethal brain tumor glioblastoma multiform (GBM). In this respect, Tau holds significant promise as a target for the development of novel therapies. Here, we examined the structure–activity relationship of a new series of seventeen 2-aminothiazole-fused to flavonoid hybrid compounds (TZF) on Tau binding, Tau fibrillation, and cellular effects on Tau-expressing cancer cells. By spectrofluorometric approach, we found that two compounds, 2 and 9, demonstrated high affinity for Tau and exhibited a strong propensity to inhibit Tau fibrillation. Then, the biological activity of these compounds was evaluated on several Tau-expressing cells derived from glioblastoma. The two lead compounds displayed a high anti-metabolic activity on cells related to an increased fission of the mitochondria network. Moreover, we showed that both compounds induced microtubule bundling within newly formed neurite-like protrusions, as well as with defection of cell migration. Taken together, our results provide a strong experimental basis to develop new potent molecules targeting Tau-expressing cancer cells, such as GBM.
