Abstract
U okviru ovog diplomskog rada spektroskopski su okarakterizirane vodene otopine tri nova derivata fenantridina s aminokiselinskim supstituentima (glicin, lizin) i gvanidinokarbonilpirolnom jedinicom. Fenantridin je poznati fluorescentni marker za polinukleotide i proteine dok aminokiselinski supstituenti pružaju dodatne mogućnosti za interakcije s biološkim makromolekulama. Konstante stabilnosti kompleksa ispitivanih spojeva s različitim DNA i RNA polinukleotidima određene su metodom fluorescencijske spektroskopije. Način vezanja peptidnih derivata fenantridina na DNA i RNA polinukleotide određen je eksperimentima temperature mekšanja polinukleotida i spektroskopijom cirkularnog dikroizma. Konstante stabilnosti kompleksa ispitivanih derivata s polinukleotidima izračunate su pomoću Scatchardove jednadžbe metodom nelinearne regresije. Dobiveni rezultati ukazuju na vezanje spojeva (najvjerojatnije u obliku dimera) u utore DNA i RNA te uzduž fosfatne okosnice polinukleotida.
Abstract (english)
In the scope of this thesis, aqueous solutions of three new phenanthridine derivatives with amino acid substituents (glycine, lysine) and a guanidinocarbonylpyrrole unit were spectroscopically characterized. Phenanthridine is a known fluorescent marker for polynucleotides and proteins. Amino acid substituents provide additional possibilities for interactions with biological macromolecules. The stability constants of the complexes of the studied compounds with different DNA and RNA polynucleotides were determined by fluorescence spectroscopy. The binding mode of peptide phenanthridine derivatives to DNA and RNA polynucleotides was determined by thermal melting experiments and circular dichroism spectroscopy. The stability constants of the compound-polynucleotide complexes were calculated by the Scatchard equation using the nonlinear regression method. The obtained results indicate the binding of compounds (most likely in the form of dimers) in the grooves of DNA and RNA and along the phosphate backbone of polynucleotides.
