  Synthesis, X-ray crystal structure and cytotoxicity of a new tetranuclear ruthenium arene complex

  摘要：

  The tetranuclear ruthenium arene compound [(cym)(4)Ru-4(2)Cl-6]Cl-2 (3) (cym = eta(6)-p-cymene, 2 = 1,2-bis (di-N-methylimidazol-2-ylphosphino)ethane) was prepared and characterised by one- and two-dimensional NMR techniques. Its cytotoxicity against four different cell lines was determined and, with an approximate IC50 of > 100 mu M 3 can be regarded as non-toxic. Its partition coefficient in n-octanol/water (log D-7.4) was also determined. The structures of complex 3 as well as of the related compound [(cym)(2)Ru-2(4)Cl-2]Cl-2 (5) (4 = 1,2-bis(di-N-methylimidazol-2-ylphosphino)ethane dioxide) were determined by single crystal structure analysis. Upon oxidation in protic solvents, ligand 2 shows P-C bond cleavage reactions to yield P,P'-bis(N-methylimidazol-2-yl)ethylene diphosphinic acid (6). (C) 2010 Elsevier B.V. All rights reserved.

  摘要：

  研究人员制备了咪唑和噻唑二磷配体的金（I）配合物，并对其作为化疗药物的潜力进行了研究。根据所用配体和反应条件的不同，可以得到[L(AuCl)2]和[L2Au]X（X = Cl，PF6）配合物。使用的配体是带有偶氮取代基 R2P(CH2)2PR2 {R = 1-甲基咪唑-2-基（1），1-甲基苯并咪唑-2-基（4）、噻唑-2-基 (5) 和苯并噻唑-2-基 (6)} 以及新型配体 RPhP(CH2)2PRPh {R = 1-甲基咪唑-2-基 (3)} 和 R2P(CH2)3PR2 {R = 1-甲基咪唑-2-基 (2)}。评估了这些配合物对三种人类癌细胞系和一种大鼠肝癌细胞系的细胞毒性活性，并将其与化合物的亲脂性联系起来。具有中等亲油性（logD7.4 = 0.21 和 0.25）的四面体金配合物 [(3)2Au]PF6 和 [(5)2Au]PF6 在不同细胞系中显示出显著的细胞毒性活性。这两种化合物都能诱导细胞凋亡并抑制硫代氧化还原酶和谷胱甘肽还原酶。

  Seven novel imidazole and thiazole derivatives of diphos-type ligands are presented. They are of the general structure R(2)P(CH(2))(2)PR(2), where R is imidazol-2-yl (1), 1-methylimidazol-2-yl (2), 1-methyl-benzimidazol-2-yl (3), 1-methylimidazol-5-yl (4), 2-isopropylimidazol-4(5)-yl (5), thiazol-2-yl (6), benzothiazol-2-yl (7), thiazol-4-yl (8) or thiazol-5-yl (9). Syntheses involved direct metallation or halogen-metal exchange reactions. Their solubility, especially in aqueous solution, is strongly dependent on the nature of the substituents as is their partition coefficient log D. The crystal structures of compounds 2, 3, 7a and 9 as well as the structure of the rhodium complex [(2)(2)Rh(2)Cl(2)]Cl(2) (10) have been determined. (C) 2010 Elsevier B. V. All rights reserved.
