A series of novelruthenium(II)-cymene complexes (1–9) with substituted α-dicarbonylmonoximes of general formula [Ru(η6-cymene)(L)Cl] (L = N,O-chelating bidentate α-dicarbonylmonoxime derivatives) have been synthesized and characterized by elemental analysis, IR, 1H NMR, 13C NMR spectroscopies, and in three cases by single crystal X-ray diffraction analysis. The most effective compound 9 displays remarkable
一系列新颖的钌(II)配合物-cymene(1 - 9)与取代α通式-dicarbonylmonoximes的[Ru(η 6 -cymene)(L)CL](L = N,O-二齿螯合α -dicarbonylmonoxime衍生物)已通过元素分析,IR,1 H NMR,13 C NMR光谱合成,并在三种情况下通过单晶X射线衍射分析进行了表征。最有效的化合物9在对三种不同的人类癌细胞系(MCF-7,Hela和HepG2)没有明显的细胞毒性的情况下,它具有出色的抗侵袭和抗转移特性。进一步的蛋白质水平研究表明,复合物的抗转移活性可能是由于E-钙粘蛋白表达的增加和波形蛋白的表达减少所致。

Abstract (±)-cis-2-amino-1-indanol was diastereoselectively synthesized from 1,2-indanedion-2-oxime in ethanol at 25 °C under 10% Pd/C-catalyzed hydrogenation conditions. Under the same hydrogenation condition, 1,2-indanedion-2-oxime and their derivatives having one and/or two electron-donating groups in aliphatic or aromatic part of indanyl ring were diastereoselectively reduced to racemic cis-2-amino-1-indanol
