  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。

  Antitumor Benzothiazoles. 8. Synthesis, Metabolic Formation, and Biological Properties of the C- and N-Oxidation Products of Antitumor 2-(4-Aminophenyl)benzothiazoles

  摘要：

  2-(4-Aminophenyl)benzothiazoles 1 and their N-acetylated forms have been converted to C- and N-hydroxylated derivatives to investigate the role of metabolic oxidation in the mode of action of this series of compounds. 2-(4-Amino-3-methylphenyl)benzothiazole (1a, DF 203, NSC 674495) is a novel and potent antitumor agent with selective growth inhibitory properties against human cancer cell lines. Very low IC50 values (<0.1 mu M) were encountered in the most sensitive breast cancer cell lines, MCF-7 and T-47D, whereas renal cell line TK-10 was weakly inhibited by la. Cell lines from the same tissue origin, MDA-MB-435 (breast), CAKI-1 (renal), and A498 (renal), were insensitive to 1a. Accumulation and metabolism of la were observed in sensitive cell lines only, with the highest rate of metabolism occurring in the most sensitive MCF-7 and T-47D cells. Thus, differential uptake and metabolism of 1a by cancer cell lines may underlie its selective profile of anticancer activity. A major metabolite in these sensitive cell lines has been identified as 2-(4-amino-3-methylphenyl)-6-hydroxybenzothiazole (6c). Hydroxylation of 1a was not detected in the homogenate of previously untreated MCF-7, T-47D, and TK-10 cells but was readily observed in homogenates of sensitive cells that were pretreated with 1a. Accumulation and covalent binding of [C-14]1a derived radioactivity was observed in the sensitive MCF-7 cell line but not in the insensitive MDA-MB-435 cell line. The mechanism of growth inhibition by 1a, which is unknown, may be dependent on the differential metabolism of the drug to an activated form by sensitive cell Lines only and its covalent binding to an intracellular protein. However, the 6-hydroxy derivative 6c is not the 'active' metabolite since, like all other C- and N-hydroxylated benzothiazoles examined in this study, it is devoid of antitumor properties in vitro.

  Pittsburgh Compound-B (PIB) is currently being evaluated clinically for in vivo visualization of amyloid plaques in patients with Alzheimer's disease (AD). We have synthesized three structural isomers of 6-hydroxy-2-(4'-aminophenyl)-1,3-benzothiazole, performed radiolabelling with carbon-11 and investigated their in vivo and in vitro properties. Specific binding to amyloid plaques was demonstrated in vitro using post-mortem brain homogenates of AD patients, transgenic AD mice brain sections and postmortem human AD brain sections. In normal mice, initial brain uptake (at 2 min p.i.) was high and was followed by a fast wash-out. The three structural analogues have a high potential as tracer agents for in vivo visualization of amyloid plaques in AD patients. (C) 2008 Elsevier Masson SAS. All rights reserved.
