  Synthesis and cytotoxicity studies of 3,5-diaryl N-acetyl pyrazoline—isatin hybrids

  摘要：

  Numerous reports highlighting the cytotoxic effects of 3,5-diaryl N-acetyl-pyrazolines and isatin tempted us to synthesise conjugates of the functionalities via alkyl armed triazole tetheration. The hybrids were synthesized by click chemistry approach and were evaluated against a panel of cell lines i.e. viz HeLa (cervix cancer), CAKI-I (Renal cancer), PC-3 (Prostate cancer) and Miapaca-2 (pancreatic cancer). The hybrids were classified into right-handed and left-handed conjugates on the basis of the placement of the isatin ring. The length of the alkyl armed triazole linker was varied from 2 to 6. Structure activity relationship has also been presented. A preliminary cytotoxic assay was performed on the series of 3,5-diaryl N-acetyl-pyrazolines and only the potent 3,5-diaryl N-acetyl-pyrazolines were selected for their inclusion in the hybrid scaffold. Among the cell lines employed, HeLa cell line was the most sensitive towards the exposure of test compounds. Out of all the compounds evaluated, two right-handed conjugates MI-7b and MI-8b and two left-handed conjugates MI-4b, MI-6b displayed significant cytotoxic potential and exhibited an IC50 range from 1.3 to 3.5 mu M against HeLa Cell line..

  A tissue is imaged to detect the presence of amyloid deposits or other target proteins prior to their aggregation into plaques, with the assistance of the administration of a labeled bifunctional compound of which one functionality binds to the target protein and the second functionality binds to a chaperone protein that is present in the tissue of interest. The two functionalities have different binding affinities, the target-binding functionality having the greater binding affinity, with the result that the bifunctional compound preferentially remains in the tissue when bound to the chaperone and then the target protein while bifunctional compound that is not bound to the target protein will leave the tissue. The inclusion of the chaperone allows the imaging process to detect the non-aggregated proteins by way of the label and the difference in kinetics of the binding to the chaperone and the target protein permits one to distinguish between binding of the bifunctional molecule to the chaperone only and binding to the chaperone and then to the target protein. Certain intermediates toward the synthesis of these bifunctional compounds are novel by themselves, and labeled bifunctional molecules in general that utilize a lysine linker are also disclosed as a novel class of compounds.

  一种组织被成像以检测淀粉样沉积物或其他靶蛋白质在聚集成斑块之前的存在，辅助使用一种带标记的双功能化合物的管理，其中一个功能性结合到靶蛋白质，第二个功能性结合到存在于感兴趣组织中的分子伴侣蛋白。这两种功能性具有不同的结合亲和力，结合到靶蛋白质的功能性具有更强的结合亲和力，结果是双功能化合物在与分子伴侣和靶蛋白质结合时更倾向于留在组织中，而未与靶蛋白质结合的双功能化合物会离开组织。包括分子伴侣可以使成像过程通过标记和结合到分子伴侣和靶蛋白质的结合动力学差异来检测非聚集的蛋白质，从而使人们能够区分双功能分子仅与分子伴侣结合和先与分子伴侣结合然后与靶蛋白质结合之间的区别。这些双功能化合物的合成中间体本身是新颖的，同时也公开了一种利用赖氨酸连接物的带标记双功能分子作为一种新颖类化合物。

  order to ascertain the binding interactions of the synthesized derivatives to the MAO-A target protein, molecular docking was employed which demonstrated the key interactions with the amino acid residues Asn181, Phe208, Tyr69, Tyr197, Tyr444 and Met445 at the binding site. In addition, the most active derivatives 2i and 2b showed some imperative conserved interactions of the PDB co-crystal ligand 2Z5X

We have now systematically examined the structural features essential for inhibition of this pathway, revealing characteristics of compounds that inhibited all TLRs tested (pan‐TLR signaling inhibitors) as well as compounds that selectively inhibited certain

  免疫系统使用Toll样受体（TLR）家族的成员识别各种病原体和宿主衍生的分子，从而启动免疫反应。尽管TLR介导的促炎性免疫反应对于宿主防御至关重要，但长时间而过度的激活会导致炎症病理，表现为多种疾病。因此，TLR信号通路的小分子抑制剂有望作为抗炎药。我们先前发现了一类三芳基吡唑化合物，可通过调节该途径必不可少的蛋白质间相互作用来抑制TLR信号传导。现在，我们已经系统地研究了抑制该途径必不可少的结构特征，揭示了可抑制所有测试的TLR的化合物（pan-TLR信号抑制剂）以及选择性抑制某些TLR的化合物的特征。这些发现揭示了有趣的化合物类别，可以针对由不同TLR控制的特定炎症疾病进行优化。
