  Synthesis, anticancer activity and docking of some substituted benzothiazoles as tyrosine kinase inhibitors

  摘要：

  Protein tyrosine kinases occupy a central position in the control of cellular proliferation and its inactivation might lead to the discovery of a new generation anticancer compounds. Substituted benzothiazoles have been found to mimic the ATP-competitive binding of genistein and quercetin to tyrosine kinase. A series of novel 2-phenyl-1,3-benzothiazoles were synthesized and characterised by IR, H-1 NMR and mass spectroscopy. All the compounds were tested for their anticancer activity against MCF-7 breast cancer cell line with the MTT assay. Most of the compounds showed moderate to good anti-breast cancer activity. Anticancer activity varied with substitution on the benzothiazole nucleus with halogens and at 4 position, substitution of the 2-phenyl moiety with methyl and methoxy groups was also explored. Among the compounds tested with MTT assay, mono fluoro substitution on benzothiazole nucleus and 4'-methyl variations at 2-phenyl position demonstrated highest percent growth inhibition of MCF-7 cells. Docking studies of the synthesised compounds was done on EGFR using GRIP batch docking method to study their observed activity. (C) 2010 Elsevier Inc. All rights reserved.

  An interesting radical coupling reaction of aromatic aldehydes with isocyanides was disclosed for the synthesis of amides catalyzed by copper. According to the experimental results and mechanistic study, the isocyano group acted as an N1 synthon rather than exhibiting the carbene-like reactivity, exploiting a new reactivity profile of isocyanides.

• Studies towards the Design and Synthesis of Novel 1,5-Diaryl-1H-imidazole-4-carboxylic Acids and 1,5-Diaryl-1H-imidazole-4-carbohydrazides as Host LEDGF/p75 and HIV-1 Integrase Interaction Inhibitors

  Two targeted sets of novel 1,5-diaryl-1H-imidazole-4-carboxylic acids 10 and carbohydrazides 11 were designed and synthesized from their corresponding ester intermediates 17, which were prepared via cycloaddition of ethyl isocyanoacetate 16 and diarylimidoyl chlorides 15. Evaluation of these new target scaffolds in the AlphaScreenTM HIV-1 IN-LEDGF/p75 inhibition assay identified seventeen compounds exceeding the pre-defined 50% inhibitory threshold at 100 µM concentration. Further evaluation of these compounds in the HIV-1 IN strand transfer assay at 100 μM showed that none of the compounds (with the exception of 10a, 10l, and 11k, with marginal inhibitory percentages) were actively bound to the active site, indicating that they are selectively binding to the LEDGF/p75-binding pocket. In a cell-based HIV-1 antiviral assay, compounds 11a, 11b, 11g, and 11h exhibited moderate antiviral percentage inhibition of 33–45% with cytotoxicity (CC50) values of >200 µM, 158.4 µM, >200 µM, and 50.4 µM, respectively. The antiviral inhibitory activity displayed by 11h was attributed to its toxicity. Upon further validation of their ability to induce multimerization in a Western blot gel assay, compounds 11a, 11b, and 11h appeared to increase higher-order forms of IN.

  设计和合成了两组新型的1,5-二芳基-1H-咪唑-4-羧酸类化合物10和羧酰肼类化合物11，它们是从它们对应的酯中间体17合成的，这些酯中间体是通过乙酰氰乙酸乙酯16和二芳基咪唑基氯化物15的环加成反应制备的。在AlphaScreenTM HIV-1 IN-LEDGF/p75抑制试验中评估了这些新的目标结构，发现17种化合物在100微米浓度下超过了预定义的50%抑制阈值。在100微米浓度下对这些化合物进行HIV-1 IN链转移试验的进一步评估显示，除了10a、10l和11k（具有边缘抑制百分比）之外，其他化合物均未活跃地结合到活性位点，表明它们选择性地结合到LEDGF/p75结合口袋。在基于细胞的HIV-1抗病毒试验中，化合物11a、11b、11g和11h表现出中等抗病毒百分比抑制率为33-45%，细胞毒性（CC50）值分别为>200微米、158.4微米、>200微米和50.4微米。11h表现出的抗病毒抑制活性归因于其毒性。通过在Western blot凝胶试验中验证它们诱导多聚体形成的能力，化合物11a、11b和11h似乎增加了IN的高阶形式。

  Cycling between Au(i) and Au(iii) is challenging, so gold-catalyzed cross-couplings are rare. The (MeDalphos)AuCl complex, which we showed was prone to undergo oxidative addition, is reported here to efficiently catalyze the C-N coupling of aryl iodides and amines. The transformation does not require an external oxidant or a directing group. It is robust and works with a wide scope of aryl iodides

  Au（i）和Au（iii）之间的循环具有挑战性，因此金催化的交叉偶联很少见。我们报道了（MeDalphos）AuCl络合物易于氧化加成的反应，据报道，该络合物可有效催化芳基碘化物和胺的CN偶联。该转化不需要外部氧化剂或导向基团。它坚固耐用，可在温和条件下与各种范围的芳基碘化物和N-亲核试剂一起使用。包括关键芳基酰胺基Au（iii）配合物的NMR和MS表征在内的机理研究强烈支持2e氧化还原循环，其中氧化加成先于重金属化，还原消除是速率确定的步骤。
