Abstract

Bioinorganic, together with medicinal chemistry, has benefited from the use of metallopharmaceuticals as drugs and therapeutic agents. In this context, several researchers have been dedicated to the synthetic chemistry of coordination compounds with medicinal application, searching for new compounds with biological activity and modeling the existing ones to reduce the their side effects. Among those studied in the literature, ruthenium compounds stand out, which have shown positive results in terms of anticancer and antimetastatic activity. Thus, this project is based on the synthesis and characterization of complexes, which may have the following structural formulas: [Ru(L)(dppe)(bipy)]PF6, [Ru(L)(dppb)(bipy)]PF6, [Ru(L)(DPEPhos)(bipy)]PF6, where L = lausone derivatives, bipy = 2,2'-bipyridine, dppe = 1,2'-bis(diphenylphosphine)ethane and DPEPhos = Bis[2-(diphenylphosphine) phenyl]ether. The complexes will be characterized by the following techniques: elemental analysis, conductivity, absorption spectroscopy in the infrared and ultraviolet and visible regions, cyclic and square wave voltammetry, nuclear magnetic resonance of 31P{1H}, 1H and 13C and X-ray diffraction. The newly synthesized complexes will be evaluated for their cytotoxic activities in prostate (DU-145), lung (A549), breast (MCF-7 and MDA-MB-231) and non-tumor breast (MCF-10A) cancer cell lines. ) and which ones present better results submitted to new biological studies. The results through chemical and biological data will provide subsidies to formulate a possible mechanism of action for the complexes. (AU)
