    <ns1:description language="sr">Predmet ove doktorske disertacije obuhvata sintezu, karakterizaciju iispitivanje antimikrobne i citotoksične aktivnosti osam novih kompleksa srebra(I)sa azolima koji se koriste za lečenje gljivičnih infekcija (klotrimazol, ekonazol ivorikonazol). Za karakterizaciju sintetisanih kompleksa korišćene su NMR, IR i UVVis cpektroskopske metode, masena spektrometrija i ciklična voltametrija. Sastav ičistoća kompleksa su potvrđeni primenom elementalne mikroanalize, dok je kristalnastruktura određena metodom rendgenske strukturne analize. Kvantno-mehaničkiproračuni su korišćeni u cilju utvrđivanja termodinamički najpovoljnije strukturekompleksa u rastvoru. Ispitivana je aktivnost sintetisanih kompleksa srebra(I) premarazličitim bakterijskim i gljivičnim sojevima, pri čemu su utvrđene minimalneinhibitorne koncentracije (MIC) u opsegu od 0,01 – 49,2 μM, dok je citotoksičnipotencijal određen na zdravoj ćelijskoj liniji fibroblasta pluća, sa IC50 vrednostimaod 10 – 36,1 µM. Pored toga, ispitivana je i sposobnost inhibicije formiranjabiofilmova, pri čemu je zabeleženo smanjenje formiranja biofilma od 77 do 90%.U Opštem delu disertacije prikazan je pregled lekova koji se koriste u terapijigljivičnih infekcija, uz poseban osvrt na pojavu i rast rezistentnostimikroorganizama na konvencionalne antigljivične lekove. Akcenat je stavljen i naznačaj kompleksnih jedinjenja u medicini sa fokusom na antimikrobna svojstvakompleksa srebra(I). Drugi deo disertacije obuhvata metodologiju sinteze kompleksasrebra(I) sa azolima i metode spektroskopske, kristalografske i biološke analize.Završni deo disertacije posvećen je diskusiji rezultata, uključujući interpretacijuspektroskopskih i kristalografskih podataka, kao i procenu antimikrobne icitotoksične aktivnosti sintetisanih jedinjenja i rezultata teorijskih proračuna. </ns1:description>
    <ns1:description language="en">The subject of this doctoral dissertation is related to the synthesis, characterization, andevaluation of the antimicrobial and cytotoxic activities of eight new silver(I) complexes withazoles used in the treatment of fungal infections (clotrimazole, econazole, and voriconazole).The synthesized complexes were characterized using NMR, IR, and UV-Vis spectroscopicmethods, mass spectrometry, and cyclic voltammetry. The composition and purity of thecomplexes were confirmed by elemental microanalysis, while their crystal structures weredetermined by single crystal X-ray diffraction analysis. Quantum-mechanical calculations wereemployed to determine the thermodynamically favorable structures of the complexes insolution. The activity of the synthesized silver(I) complexes was tested against various bacterialand fungal species, with minimum inhibitory concentration (MIC) values ranging from 0.01 to49.2 μM. The cytotoxic potential was assessed on a healthy human lung fibroblast cell line,yielding IC50 values in the range of 10 – 36.1 µM. In addition, the ability of the complexes toinhibit biofilm formation was investigated, revealing a reduction in biofilm formation of 77 –90%.The Introductory section of the dissertation provides an overview of antifungal drugscurrently used in therapy, with particular emphasis on the emergence and increasing resistanceof microorganisms to conventional antifungal agents. Special attention is also given to theimportance of coordination compounds in medicine, focusing on the antimicrobial propretiesof silver(I) complexes. The second part of the dissertation describes the syntetics proceduresfor the preparation of silver(I)-azole complexes, as well as the spectroscopic, crystallographicand biological methods applied for their characterization. The final section of the dissertationis devoted to the discussion of the results, including the interpretation of spectroscopic andcrystallographic data, as well as the evaluation of antifmicrobial and cytotoxic activities andtheoretical calculations.</ns1:description>
