Abstract
U zadnjih nekoliko desetljeća antioksidansi su postali čest predmet znanstvenih istraživanja zbog njihove uloge u oksidativnom stresu i etiologiji mnogih bolesti. U ove se spojeve ubraja širok spektar prirodnih mono- i polifenolnih spojeva, primjerice fenolne kiseline, ali i značajan broj sintetskih polifenolnih spojeva. U ovom radu dan je pregled teoretskih istraživanja antioksidacijskog potencijala odabranih fenolnih kiselina. U okviru rada razmatrani su odgovarajući termodinamički parametri ključni za pojedini mehanizam antioksidacijske aktivnosti, na temelju kojih se može izvući zaključak o njihovom antioksidacijskom potencijalu. Osim toga, u radu su prikazani rezultati ispitivanja reakcije fenolnih kiselina s odabranim slobodnim radikalima a ispitani mehanizmi bili su HAT, SET-PT, SPLET i RAF, pri čemu su ispitivanja provedena u nepolarnom i polarnom mediju. Na osnovu izračunatih parametara, određeno je koji su mehanizmi mogući i međusobno kompetitivni te koja od ispitivanih fenolnih kiselina ima veći antiokisidacijski potencijal.
Abstract (english)
In the last several decades, antioxidants have become frequent subject of scientific investigations due to their role in oxidative stress and aetiology of various diseases. Antioxidants include a broad spectrum of mono- and polyphenolic compounds, such as phenolic acids, and also a significant number of synthetic polyphenolic compounds. In this thesis, an overview of theoretical research on antioxidant potential of selected phenolic acids was given. Adequate thermodynamic parameters which play the key role in selected mechanisms of antioxidant activity were also studied and a conclusion regarding antioxidant potential was drawn from this study. Additionally, results of studies of reactions of phenolic acids with free radicals were presented, and studied mechanisms were HAT, SET-PT, SPLET and RAF, in polar and non-polar medium. Based on the results of computed parameters, possible and competitive mechanisms were determined, as well as phenolic acids with higher antioxidant potential.
