    摘要:
    作为信号转导和转录激活因子 (STAT) 家族的成员,STAT3 在细胞增殖、迁移、存活和分化等多种生物学途径中发挥着关键作用。由于肿瘤中的异常持续激活,抑制 STAT3 已成为治疗各种癌细胞的有吸引力的方法。在此,我们报告了一系列基于苯并[b]噻吩 1,1-二氧化物支架的新型 STAT3 抑制剂,并评估了它们的抗癌效力。其中,化合物8b对癌细胞表现出最好的活性。化合物8b诱导细胞凋亡并阻断细胞周期。同时,8b减少细胞内 ROS 含量并导致线粒体膜电位丧失。进一步的研究表明,8b显着阻断了 STAT3 磷酸化,并且 STAT3 依赖性双荧光素酶报告基因实验表明,化合物8b对 STAT3 介导的萤火虫荧光素酶活性具有显着抑制作用。分子模型研究表明,化合物8b以良好的构象占据了具有 SH2 结构域的口袋。

    STAT3 has been extensively studied as a potential antitumor target. Though studies on regulating STAT3 mainly focus on the inhibition of STAT3 phosphorylation at Tyr705 residue, the phosphorylation at Ser727 residue of STAT3 protein is also closely associated with the mitochondrial import of STAT3 protein. N, N-diethyl-7-aminocoumarin is a fluorescent mitochondria-targeting probe. In this study, a
    STAT3已被广泛研究为潜在的抗肿瘤靶标。尽管关于调节STAT3的研究主要集中在抑制Tyr705残基上的STAT3磷酸化,但是STAT3蛋白的Ser727残基上的磷酸化也与STAT3蛋白的线粒体导入密切相关。N,N-二乙基-7-氨基香豆素是一种荧光的线粒体靶向探针。在这项研究中,通过将N,N-二乙基-7-氨基香豆素荧光团与苯并[ b ]噻吩1,1-二氧化物部分相连,开发了一系列STAT3抑制剂。所有设计的化合物均显示出对癌细胞有效的抗增殖活性。代表性化合物7a主要通过荧光可见的线粒体中积累。化合物7a在Tyr705和Ser727残基均抑制STAT3磷酸化。化合物7a抑制STAT3磷酸化,而对STAT1,JAK2,Src和Erk1 / 2的磷酸化水平没有影响,表明化合物7a具有良好的选择性。此外,化合物7a下调STAT3靶基因Bcl-2和Cyclin D1的表达,增加ROS的产生并显着降低线

    Positive allosteric modulators (PAMs) of nicotinic acetylcholine receptors (nAChR) are important therapeutic candidates as well as valuable research tools. We identified a novel type II PAM, (R)-7-bromo-N-(piperidin-3-yl)benzo[b]thiophene-2-carboxamide (Br-PBTC), which both increases activation and reactivates desensitized nAChRs. This compound increases acetylcholine-evoked responses of α2* and α4* nAChRs, but is without effect on α3* or α6* nAChRs ("*" indicates presence of other nAChR subunits). Br-BPTC binds to the C-terminal extracellular sequences of a4 subunits, which is also a PAM site for steroid hormone estrogens such as 17-β estradiol. Br-PBTC is much more potent than estrogens. Like 17-P-estradiol, the non-steroid Br-PBTC only requires one α4 subunit to potentiate nAChR function, and its potentiation is stronger with more a4 subunits. This feature enables Br-BPTC to potentiate activation of (α4β2)(α6β2)β3 but not (α6β2)2β3 nAChRs. Various bioactive analogs of Br-PBTC are provided.
    正向变构调节剂(PAMs)对尼古丁乙酰胆碱受体(nAChR)是重要的治疗候选药物,同时也是有价值的研究工具。我们发现了一种新型II型PAM,(R)-7-溴-N-(哌啶-3-基)苯并[b]噻吩-2-甲酰胺(Br-PBTC),它既增加了激活,又重新激活了脱敏的nAChRs。这种化合物增加了α2*和α4* nAChRs对乙酰胆碱的响应,但对α3*或α6* nAChRs没有影响("*"表示存在其他nAChR亚基)。Br-BPTC结合到α4亚基的C端外胞外序列,这也是类固醇激素雌激素如17-β雌二醇的PAM位点。Br-PBTC比雌激素更有效。与17-β雌二醇一样,非类固醇Br-PBTC只需要一个α4亚基来增强nAChR功能,并且随着更多的α4亚基,其增强作用更强。这个特性使Br-BPTC能够增强(α4β2)(α6β2)β3而不是(α6β2)2β3 nAChRs的激活。提供了各种生物活性类似物的Br-PBTC。
