to be highly selective chemosensors for fluorideions only. To investigate in detail the mechanism of selective fluorideion sensing, detailed spectroscopic studies were carried out using UV-visible, fluorescence and 1H NMR spectroscopy. Fluoride mediated (NH) proton abstraction of acridinedione was found to be responsible for the observed selective fluorideion sensing. Quantum mechanical computational

We have developed green, efficient and powerful protocols for the preparation of 2,4,6‐triarylpyridines and 1,8‐dioxodecahydroacridines in the presence of Fe3O4@TiO2@O2PO2(CH2)2NHSO3H as a sulfonic acid‐functionalized titana‐coated magnetic nanoparticle catalyst under mild and solvent‐free reaction conditions. These protocols furnished the desired products in short reaction times with good to high
我们已开发出在Fe 3 O 4 @TiO 2 @O 2 PO 2(CH 2)2 NHSO 3存在下制备2,4,6-三芳基吡啶和1,8-二氧杂脱氢hydro啶的绿色,高效且有力的方法H在温和无溶剂的反应条件下作为磺酸官能化的钛包覆磁性纳米粒子催化剂。这些方案可在较短的反应时间内提供所需的产物,并具有良好的高收率(对于2,4,6-三芳基吡啶,为20–40分钟和80–86%;对于2,4,6-三芳基吡啶为15–90分钟和80–93% 1,8-二氧杂十二烷基hydro啶)。机械合成2,4,6-三芳基吡啶的最后一步是通过基于异头的氧化进行的。同样,在经过仔细研究的单罐多组分反应中,具有高周转数和周转频率的纳米磁性核-壳催化剂可以循环再利用。

ABSTRACT In world, many people struggle with viral, parasitic, bacterial, cancer, and other diseases. Therefore, numerous chemists seek to develop less toxic, more selective, and effective medicines. Most therapeutic medicines are based on inhibition of specific enzymes. Acridines are interesting heterocyclic structures that are much sought after targets attributed to their wide biological activities
摘要 在世界上,许多人与病毒、寄生虫、细菌、癌症和其他疾病作斗争。因此,许多化学家寻求开发毒性更小、更具选择性和更有效的药物。大多数治疗药物基于对特定酶的抑制。吖啶是一种有趣的杂环结构,由于其广泛的生物活性和表现出强大的酶抑制作用的特征而备受追捧。它们的作用方式是由于 DNA 相互作用以及随后对与 DNA 和相关酶相关的生物功能的影响。在这方面,我们通过 1,4-二氮杂双环 [2.2.2] 辛烷 (DABCO)-聚乙二醇-400 (PEG-400) 介导的离子液体方法合成了吖啶类似物。DABCO-PEG-400 介导的 IL 使用 1-溴戊烷通过 DABCO 烷基化制备,然后与 PEG-400 混合。合成的类似物被研究作为碱性磷酸酶的抑制剂,碱性磷酸酶是一种非特异性磷酸单酯水解酶,可催化广谱有机单磷酸盐的水解。模拟即。3,3,6,6-tetramethyl-9-(4-nitrophenyl)-2
