STAT3 has been extensively studied as a potential antitumor target. Though studies on regulating STAT3 mainly focus on the inhibition of STAT3phosphorylation at Tyr705 residue, the phosphorylation at Ser727 residue of STAT3protein is also closely associated with the mitochondrial import of STAT3protein. 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

日期:——
A simple 2-step synthesis of B-ring substituted benzo[b]thiophene-2-carboxylates from aryl fluorides has been developed. The route involves a selective lithiation ortho to fluorine, followed by formylation, and subsequently, displacement of fluorine with thioglycollate and base-induced ring closure in a single operation.

The present invention is related to benzothiophen-2-carbonylguanidine derivatives, a preparation method thereof, and pharmaceutical compositions containing the same. The derivatives have potent inhibitory effect on the sodium/hydrogen exchanger NHE-I, improve the functional recovery of ischemia/reperfusion-induced heart injury in isolated ischemic heart models, and significantly reduce the myocardiac infarct size in in vivo ischemic animal models, thereby showing excellent cardioprotective effects. Also, the derivatives are protective of both neuronal cells and the brain as proven by their protective effects on neuronal cells from necrosis and apoptosis and by their ability to significantly reduce cerebral infarct sizes in in vivo ischemic brain models. The derivatives can be effectively used for the prevention and treatment of ischemic heart diseases such as myocardiac infarction, arrhythmia, angina pectoris and the like, and cerebrovascular diseases such as cerebral stroke and be used as cardioprotective agents to the patients undergoing reperfusion therapy including chemicals such as thrombolytic agents, or surgery such as coronary artery bypass and percutaneous transluminal coronary angioplasty.
