  2-（4-氨基苯基）苯并噻唑衍生物作为光敏剂的合成及生物学评价

  摘要：

  使用外源光敏剂的光动力疗法（PDT）目前已被批准用于治疗基底细胞癌（BCC）。2-（4-氨基苯基）苯并噻唑（6）由发色结构组成，可吸收UVA（315-400 nm）中的光。这些结果鼓励我们设计和合成各种2-苯基苯并噻唑（6）。在本文中研究了UVC激活的6在BCC细胞中诱导的光敏效应所涉及的凋亡机制。用6 -UVA处理的细胞显示出一些凋亡特征，包括亚G1群体的增加，膜联蛋白V结合的显着增加以及caspase-3的激活。6-UVA诱导线粒体膜电位（Δ降低ψ公吨），并通过增强的ROS产生和胞外信号调节激酶（ERK）和p38 MAPK表达的促进磷酸ATP。这些结果表明6- UVA在涉及ERK和p38活化的线粒体过程中引起光敏作用，并最终导致BCC细胞凋亡。

• Metal-Free Synthesis of 2-Arylbenzothiazoles from Aldehydes, Amines, and Thiocyanate
  作者：Amrita Dey、Alakananda Hajra

  A highly efficient method for the synthesis of 2-arylbenzothiazoles has been developed using readily available aromatic amines, benzaldehydes, and NH4SCN as a sulfur source. A library of 2-arylbenzothiazoles with wide functional group compatibility has been synthesized in good yields through iodine-mediated oxidative annulation.

  已经开发了一种高效的合成2-芳基苯并噻唑的方法，该方法使用容易获得的芳族胺，苯甲醛和NH 4 SCN作为硫源。通过碘介导的氧化环化反应，以高收率合成了具有广泛官能团相容性的2-芳基苯并噻唑文库。

  The present invention relates to (3-fluoro-2-hydroxy)propyl-functionalized aryl derivatives or to the pharmaceutically acceptable salt thereof, to a method for preparing same, and to a pharmaceutical composition containing same as active ingredients for the diagnosis or treatment of neurodegenerative brain diseases. The aryl derivatives of the present invention are (3-fluoro-2-hydroxy)propyl-functionalized to increase the polarity thereof, and therefore the drugs containing the aryl derivatives can easily permeate into the cerebrovascular membrane, thus increasing the effectiveness of the drugs. As the aryl derivatives of the present invention strongly bind to β-amyloid, the aryl derivatives, when labeled with radioisotope, can be used as a diagnostic agent for non-invasively diagnosing early Alzheimer's disease. Further, the aryl derivatives of the present invention bind to low molecular β-amyloid peptide conjugates to inhibit the generation of malignant high molecular β-amyloid plaque, and thus can be effectively used as a therapeutic agent for neurodegenerative brain diseases such as Alzheimer's disease.

  本发明涉及（3-氟-2-羟基）丙基官能化芳基衍生物或其药用可接受的盐，以及制备该衍生物的方法，以及含有该衍生物作为活性成分的药物组合物，用于诊断或治疗神经退行性脑疾病。本发明的芳基衍生物经（3-氟-2-羟基）丙基官能化以增加其极性，因此含有该芳基衍生物的药物可以轻松渗透到脑血管膜中，从而增加药物的有效性。由于本发明的芳基衍生物与β-淀粉样蛋白结合强，因此当该芳基衍生物标记放射性同位素时，可用作无创诊断早期阿尔茨海默病的诊断剂。此外，本发明的芳基衍生物与低分子量β-淀粉样肽结合以抑制恶性高分子量β-淀粉样斑块的生成，因此可以有效用作治疗阿尔茨海默病等神经退行性脑疾病的治疗剂。
