Potential new inorganic antitumour agents from combining the anticancer traditional Chinese medicine (TCM) liriodenine with metal ions, and DNA binding studies
摘要:
Liriodenine (L) 是一种具有活性的抗癌中药成分,来源于樟树(Zanthoxylum nitidum)。它与 Pt(II) 和 Ru(II) 的反应生成了三种金属配合物:cis-[PtCl2(L)] (1)、cis-[PtCl2(L)(DMSO)] (2) 和 cis-[RuCl2(L)(DMSO)2]·1.5H2O (3),L、2 和 3 的晶体结构通过单晶 X 射线衍射法进行了测定。这些配合物通过元素分析、红外光谱、1H 和 13C 核磁共振谱以及电喷雾质谱进行了全面表征。对 L 及配合物 1–3 在 11 种人类肿瘤细胞系中的体外细胞毒性进行了检测。基于金属的化合物相较于游离的 L 表现出增强的细胞毒性,表明这些化合物在金属离子与 liriodenine 的结合中展现了协同作用。对 L 及其配合物 1–3 与 ct-DNA 结合特性的研究采用了紫外-可见光、荧光、圆二色谱、粘度及琼脂糖凝胶电泳等测量方法。
Phenanthrene derivatives of formula I for use as medicaments. The present invention refers to phenanthrene derivatives for use as medicaments, mainly in the prevention and/or treatment of DM1, HDL2, SCA8, DM2, SCA3, FXTAS, FTD/ALS, and SCA31. In a preferred embodiment, phenanthrene derivatives of the invention are also used as antimyotonic agents.

photoinduced acylation of N‐heterocycles is explored. This visible‐lighttriggered reaction occurs not only under extremely mild reaction conditions, but also does not require the presence of a photosensitizer. The mechanistic studies suggest formation of EDA complexes prompt to harness the energy from visible‐light. Compatibility with a large panel of α‐keto acids as acyl precursors and an array of N‐heterocycles

Noveltotalsyntheses of oxoaporphine alkaloids such as liriodenine, dicentrinone, cassameridine, lysicamine, oxoglaucine and O-methylmoschatoline were developed. The key step of these totalsyntheses is Cu-catalyzed conversion of 1-benzyl-3,4-dihydro-isoquinolines (1-Bn-DHIQs) to 1-benzoyl-isoquinolines (1-Bz-IQs) via tandem oxidation/aromatization. This novel Cu-catalyzed conversion has been studied
