Résumé :
Even though significant progress has been made in cancer treatment, there is always room for improvement. The experimental drug Ruthenium Complex II shows promise as a cancer treatment. In this article, the dichloro-3,3’-dicarboxy-2,2’-bipyridyl bis(dimethylsulphoxide)ruthenium(II) [RuCl2(3,3’-dcbpy)(DMSO)2], have been synthesized, characterized, and studied for its anticancer activity against MDA-MB-231 and MRC-5 cell lines, as well as its mechanisms of action and selectivity.

Résumé :
The new Ru(III) complex tran-[(dmso)2H]+[RuCl4(dmso)2]− (1) (dmso = S-bonded dimethylsulfoxide) has been synthesized. New synthetic routes are reported for mer-RuX3(dms)3 complexes (dms = dimethylsulfide, X = Cl (2) and Br (3)) and for trans-RuCl2(dmso)4 (4). The complexes have been studied spectroscopically while 1, 2 and 4 have also been characterized crystallographically.

Résumé :
The interaction of two antitumor ruthenium(III) complexes,-Na[trans-RuCl4(DMSO)(Im)] and Na[trans-RuCl4(DMSO)(Ind)]- with human serum apotransferrin (apoTf) was investigated through a number of spectroscopic techniques such as UV-Vis absorption, CD and H1 NMR spectroscopy. Interestingly, the hydrolysis profiles of these complexes in a physiological buffer are markedly affected by the presence, in solution, of apoTf suggesting the occurrence of a specific interaction of their respective hydrolysis products with the protein. The formation of stable adducts with apotransferrin has been demonstrat

Novel ruthenium(III) complexes with histamine[RuCl4(dmso-S)(histamineH)]⋅O(1a) and[RuCl4(dmso-S)(histamineH)](1b) have been prepared and characterized by X-ray structure analysis. Their crystal structures are similar and show a protonated amino group on the side chain of the ligand which is not very common for a simple heterocyclic derivative such as histamine. Biological assays to test the cytotoxicity of the compound1bcombined with electroporation were performed to determine its potential for future medical applications in cancer treatment.

Ruthenium(II) complexes of the thiacyclophane ligands 2,5,8-trithia[9]-o-cyclophane (TT[9]OC) and 5-oxa-2,8-dithia[9]-o-cyclophane (ODT[9]OC) were synthesized by ligand displacement reactions employing RuCl2(DMSO)4, RuCl2(PPh3)3, and RuHCl(PPh3)3 as starting materials. X-ray crystal structures of two of these complexes, RuCl2(DMSO)(TT[9]OC) and RuCl2(PPh3)(ODT[9]OC), demonstrate how TT[9]OC and ODT[9]OC bind to Ru(II).

Résumé :
Ruthenium compounds are highly regarded as potential drug candidates. The compounds offer the potential of reduced toxicity and can be tolerated in vivo. The various oxidation states, different mechanism of action, and the ligand substitution kinetics of ruthenium compounds give them advantages over platinum-based complexes, thereby making them suitable for use in biological applications. Several studies have focused attention on the interaction between active ruthenium complexes and their possible biological targets. In this paper, we review several ruthenium compounds which reportedly posses

The complexes have been evaluated as catalysts for olefin epoxidation and nitrile hydration in homogeneous phase. On the other hand, taking into account the importance and advantages of the heterogeneous catalysis, we have carried out the immobilization of some of these complexes on silica-type supports and we have evaluated their
