Abstract

Cancer is disease, which caused 12% of all human deaths worldwide each year. The combination of the two well known drugs, Cisplatin and fluorouracil, has been used for treatment of cancer. However, recently, it have been reported that the enzyme system glutathione/glutathione s-transferases (GSH/GSTs) causes tumor cells increasingly resistant to the treatment. This project proposes to use DNICs as alternative drug to cisplatin. DNICs are formed inside cells upon cellular exposure to nitric oxide (NO) and are known to bind strongly to and inhibit the GST enzyme family. Thus, we propose to synthesize and characterize new DNICs of the type [Fe(NO)2(X)2] (X = 6-mercaptopurine, captopril, thiosemicarbazones and thiocarbamoylpirazol), and [Fe(NO)2XY] (X = 6-mercaptopurine, Y = captopril, thiosemicarbazones and thiocarbamoylpirazol), where X and Y are anticancer drugs with distinct mechanisms of action. The DNIC ligands other than NO are readily replaced by GSTs aminoacid side chain groups, leading to a possible synergism of inhibiting GST and releasing anticancer agents in the same cell and simultaneously. The citotoxicity effects of these new DNIC compounds will be tested in assays using the human tumor cell lines MCF7 (ATCC - HTB-22), CHL-1(ATCC-CRL-9446), PC-03 (ATCC CRL 1435), HT-29 (ATCC HTB-38) e SNU-1 (ATCC CRL - 5971) e normal cell (ATCC - PCS-201-012) (AU)
