In this doctoral dissertation, copper(II), silver(I) and gold(III) complexes with antifungalazoles were synthesized. In the first part of this thesis, antifungal agents used in medicine for thetreatment of fungal infections are described. In addition, metal complexes with azoles as potentialtherapeutic agents are reviewed. In the second part, procedures for the synthesis of copper(II),silver(I) and gold(III) complexes with azoles (imidazole, 1-isopropylimidazole, 1-phenylimidazole,fluconazole, itraconazole, miconazole, clotrimazole, econazole, tioconazole and voriconazole) andmethods for their structural characterization and biological evaluation are given. In the part of thedissertation related to the Discussion of the obtained results, the spectroscopic and crystallographiccharacteristics of the synthesized complexes and the results obtained by evaluation of theirbiological activity (antimicrobial, antitubercular and antiproliferative) are presented in detail, aswell as their embryotoxicity in the zebrafish model Danio rerio. The synthesized complexes withdifferent azoles were structurally characterized by spectroscopic (NMR, IR, UV-Vis),electrochemical (cyclic voltammetry) and crystallographic methods (single-crystal X-raydiffraction analysis), mass spectrometry and molar conductivity measurements. The antimicrobialand antitubercular activities of the synthesized complexes were investigated and compared withtheir cytotoxicity on the healthy human lung fibroblast cell line (MRC-5). DFT calculations wereused to explain the structure of the synthesized complexes in solution. To define the mechanism ofantimicrobial action of the complexes, their interactions with ct-DNA and BSA in the absence andpresence of site markers were studied.
U okviru ove doktorske disertacije, sintetisani su kompleksi bakra(II), srebra(I) izlata(III) sa azolima koji se klinički koriste kao antifungalni agensi. U prvom deludoktorske disertacije opisani su antifungalni agensi koji se koriste u medicini zalečenje gljivičnih infekcija. Pored toga, dat je pregled kompleksa metala sa azolima kaopotencijalnim terapeutskim agensima. U drugom delu disertacije, opisani su postupci zasintezu kompleksa bakra(II), srebra(I) i zlata(III) sa azolima (imidazol,1-izopropilimidazol, 1-fenilimidazol, flukonazol, itrakonazol, mikonazol,klotrimazol, ekonazol, tiokonazol i vorikonazol) i metode za njihovu karakterizaciju ibiološko ispitivanje. U delu disertacije koji se odnosi na Diskusiju rezultata, detaljnosu prikazani rezultati spektroskopske i kristalografske karakterizacije sintetisanihkompleksa, rezultati dobijeni ispitivanjem njihove biološke aktivnosti (antimikrobne,antituberkulozne i antiproliferativne), kao i in vivo embriotoksičnost ovih kompleksana modelu zebra ribica Danio rerio. Sintetisani kompleksi su okarakterisani primenomspektroskopskih (NMR, IR, i UV-Vis), elektrohemijskih (ciklična voltametrija) ikristalografskih metoda (difrakcija X-zraka sa monokristala), kao i primenom masenespektrometrije i merenjem molarne provodljivosti. Antimikrobna i antituberkuloznaaktivnost sintetisanih kompleksa je poređena sa njihovom citotoksičnošću na zdravojćelijskoj liniji fibroblasta pluća (MRC-5). Kako bi se objasnila struktura kompleksa urastvoru, korišćeni su DFT proračuni. Pored toga, u cilju definisanja mehanizmaantimikrobnog delovanja kompleksa, ispitivane su njihove interakcije sa ct-DNA i BSA uodsustvu i prisustvu markera.
