Heterofunctional ruthenium(II) carbosilane dendrons, a new class of dendritic molecules to fight against prostate cancer.

A family of heterofunctional Schiff base carbosilane metallodendrons with [Ru(η-CH)(PTA)Cl] (PTA = 1,3,5-triaza-7-phosphatricyclo-[3.3.1.

Synthesis and Characterization of FITC Labelled Ruthenium Dendrimer as a Prospective Anticancer Drug.

Metallodendrimers-dendrimers with included metals-are widely investigated as biocompatible equivalents to metal nanoparticles. Applications can be expected in the fields of catalysis, as chemical sensors in molecular recognition and as anticancer drugs. Metallodendrimers can also mimic certain biomolecules, for example, haemoprotein in the case of using a dendrimer with a porphyrin core.

Ruthenium dendrimers against acute promyelocytic leukemia: studies on HL-60 cells.

Coordination of ruthenium arene fragments on carbosilane dendrimers' surface greatly increases their antitumor properties. Newly synthetized ruthenium dendrimers are water-soluble, monodisperse and stable. Since carbosilane dendrimers are good carriers of drugs and genes, the presence of ruthenium in their structure makes them promising candidates for new drug delivery systems with improved antitumor potential.

Ruthenium dendrimers as carriers for anticancer siRNA.

Dendrimers, which are considered as one of the most promising tools in the field of nanobiotechnology due to their structural organization, showed a great potential in gene therapy, drug delivery, medical imaging and as antimicrobial and antiviral agents. This article is devoted to study interactions between new carbosilane-based metallodendrimers containing ruthenium and anti-cancer small interfering RNA (siRNA). Formation of complexes between anti-cancer siRNAs and Ru-based carbosilane dendrimers was evaluated by transmission electron microscopy, circular dichroism and fluorescence.

Carbosilane metallodendrimers based on copper (II) complexes: Synthesis, EPR characterization and anticancer activity.

A series of new organometallic carbosilane dendrimers functionalized with Copper(II) complex on the surface were synthesized and characterized as potential anticancer agents. These metallodendrimers were synthesized through the reaction of dendritic ligands containing N,N- and N,O- donor atoms able to act as chelating agents with CuCl as metallic ion precursor. The structural characterization of these complexes was addressed through the use of different analytical and spectroscopical techniques.

Synthesis and anticancer activity of carbosilane metallodendrimers based on arene ruthenium(ii) complexes.

A series of new organometallic carbosilane dendrimers (first and second generation) and the corresponding non-dendritic mononuclear based on ruthenium arene fragments are described. The metallodendrimers were prepared by reactions of the precursor [Ru(η(6)-p-cymene)Cl2]2 with carbosilane dendrimers functionalized with N-donor monodentate ligands such as NH2- and pyridine, or with N,O-, N,N-chelating imine ligands. While the dendrimer precursors are insoluble in DMSO or water, novel metallodendrimers are soluble in DMSO and some of them are even highly soluble in water.
