N-glycoside formation. A number of the rhodanine derivatives, especially those with nitro or chloro groups in the aromatic ring, showed antibacterialactivity. N-beta-D-Glucopyranosyl-5-(4-nitrobenzylidene) rhodanine showed antiviralactivity by inhibition of viral RNA synthesis. Some effect on blood sugar levels also was observed with several rhodanines.

desirable target for fluorescent labeling. In this work, we proposed a number of new fluorogenic compounds—arylidene-rhodanines and their acyclic analogues – substances that label lipid droplets due to structural fragments responsible for the appearance of fluorescence in a lipophilic environment. Methods: The target arylidene-rhodanines and their acyclic analogues were obtained using modified literature
摘要 目的:脂滴(脂肪体)是具有独特结构和功能的细胞器,在能量稳态、脂毒性和氧化应激预防中发挥重要作用,因此是荧光标记的理想目标。在这项工作中,我们提出了许多新的荧光化合物——亚芳基绕丹宁及其无环类似物——这些物质可以标记脂滴,因为结构片段负责在亲脂环境中出现荧光。方法:使用改进的Knoevenagel缩合文献方法获得目标亚芳基绕丹宁及其无环类似物,研究所得化合物在一组标准溶剂中的光学性质,然后在Hela京都上测试最有前途的物质作为荧光染料使用宽视野显微镜观察细胞。讨论:我们发现含有 2,5-二甲氧基苯亚甲基片段或类似基团的衍生物的特征是荧光量子产率根据环境特性而发生显着变化。研究了此类化合物的细胞标记。我们发现,用物质 ( In ) 和 ( III )孵育 Hela京都细胞会导致 BFP 通道中出现荧光,这与在透射光下观察时在细胞中检测到的脂滴位置相关。结论:结果,我们发现所获得的两种化

benzylidene derivatives via a direct sp3 C–H olefination reaction of enolizable carbonyls. We remarkably emphasize the synthetic utility of these derivatives and validate the molecular structures using 1H-NMR and 13C-NMRspectroscopy (APT) as well as SC-XRD investigation of representative compounds.
