Abstract
U ovom diplomskom radu opisane su sinteze meta i para supstituiranih N-aril-3- hidroksipiridin-4-ona (3-7) i njihovih α-D-manozida (13-16). Piridinonski prekursori 3-7 priređeni su modificiranom Harrisovom metodom iz 5-benziloksipiran-4-on-2-karboksilne kiseline (2), dobivene iz komercijalno dostupne kojične kiseline, i odgovarajućih anilina (m- i p-metilanilina, m- i p-nitroanilina te m-metoksianilina) uz dodatak kiselog katalizatora (p- TsOH) zagrijavanjem u zatvorenoj teflonskoj posudi (autoklav). Spojevi 3-7 prevedeni su u acetilirane manozne derivate (8-11) pomoću 2,3,4,6-tetra-O-acetil-1-brom-α-D-manopiranoze uz AgOTf kao promotor i kolidin (Koenigs-Knorrova metoda glikozidacije). Uklanjanjem acetatnih skupina s manozne podjedinice spojeva 8-11 Zemplénovim postupkom priređene su ciljne molekule, N-aril-3-hidroksipiridin-4-onskih α-manozidi (13-16), kojima je ispitan inhibitorski učinak u procesu adhezije E. coli na stanice eritrocita. Strukture svih priređenih spojeva određene su spektroskopijom NMR (1H i 13C) i spektrometrijom masa (MS).
Abstract (english)
In this diploma thesis the syntheses of meta and para substituted N-aryl 3-hydroxypyridin-4- ones (3-7) and their α-D-mannosides (13-16) are described. Pyridinone precursors 3-7 were prepared by Harris method from 5-benzyloxypyran-4-one-2-carboxylic acid (2) and corresponding anilines (m- and p-methylaniline, m- and p-nitroaniline and m-methoxyaniline) with the addition of acid catalyst (p-TsOH) and heathing in a sealed Teflon container (autoclave). Compound 2 was synthesized from commercially available kojic acid. Acetylated mannose derivatives (8-11) were obtained by Koenigs-Knorr glycosidation using 2,3,4,6- tetra-O-acetyl-1-bromo-α-D-mannopyranose, collidine and AgOTf as promoter. The target compounds, N-aryl 3-hydroxypyridin-4-one α-mannosides (13-16), were prepared by removal of acetyl groups from mannose subunit in compounds 8-11 (Zemplén procedure). The inhibitory activity of target molecules 13-16 in the E. coli adhesion to erythrocyte cells was evaluated. The structures of all prepared compounds were determined by NMR (1H i 13C) spectroscopy and mass spectrometry (MS).
