Synthesis of Multitopic Verdazyl Radical Ligands. Paramagnetic Supramolecular Synthons
摘要:
The syntheses of several verdazyl radical and diradicals containing pyridine-based multitopic coordination sites are described. These compounds were designed to be paramagnetic analogues of oligopyridine metallosupramolecular building blocks.

was also explored.Text: Chiral polyamines have been utilized for a variety of applications. First, polyamines are polycationic at neutral pH; as such, they interact strongly with both DNA and RNA.1 They can therefore be utilized as effective nonviral gene delivery agents.2 Second, chiral polyamines are efficient catalysts for various organic transformations.3 Polyamines have also been used to solubilize
手性多胺可用于各种潜在应用,从不对称催化到 DNA 和 RNA 的非病毒基因传递系统。它们还可用于溶解碳纳米管。因此,需要直接合成手性多胺的方法。我们在此提出了两种用于获得手性多胺的合成策略。还探索了这些手性胺催化两种具有高度手性诱导的有机反应的潜力。文本:手性多胺已用于多种应用。首先,多胺在中性 pH 值下是聚阳离子的;因此,它们与 DNA 和 RNA 有很强的相互作用。1 因此它们可以用作有效的非病毒基因传递剂。2 其次,手性多胺是各种有机转化的有效催化剂。3 多胺也已用于溶解碳纳米管。4 最后,手性多胺是许多过渡金属的极好配体。5 由于其应用众多,因此对其制备的高产合成策略有很大的需求。我们在此提出了获得手性多胺的两种合成策略,以及这些手性胺催化两种有机反应的潜力。
Synthesis, topoisomerase I inhibition and structure–activity relationship study of 2,4,6-trisubstituted pyridine derivatives
For the development of new anticancer agents, phenyl, 2-pyridyl, 2-furyl, 2-thienyl, 2-furylvinyl and 2-thienylvinyl substituted derivatives on 2,4,6-position in pyridine moiety were prepared and evaluated for their topoisomerase I inhibitory activity. Among the thirteen prepared compounds, four compounds exhibited strong topoisomerase I inhibitory activity. A structure-activity relationship study

Efficient and environmentally friendly synthesis of chalcone and azachalcone was performed by aldol condensation of aldehydes with ketones in pure water catalyzed by sodium carbonate. In this convenient methodology, side reactions were avoided and thus high yields were achieved.
A series of pyrimidine-based compounds have been synthesized. Methyl (1) and amino (2) substituted compounds emitted fluorescence in solution. From the solvent effect on their emission spectra, the mechanism of emission was different in 1 and 2, and the emission of 2 contains the internal charge transfer process.
