Abstract
U sklopu diplomskog rada opisana je priprava triju ferocenskih estera manoziliranog desmuramil-dipeptida, L-Ala-D-isoGln. Konvergentnim pristupom sintezi najprije su zasebno pripravljena tri fragmenta: manozna podjedinica s razmaknicom od dva atoma ugljika (C2 razmaknica), dipeptid te ferocenski alkoholi, koji su zatim povezani u jednu cjelinu. Benzilima zaštićena manozna podjedinica s C2 razmaknicom pripremljena je u dva sintetska koraka iz 2,3,4,6-tetra-O-benzil-α-D-manopiranoze. Kao polazni dipeptid korišten je komercijalno dostupni zaštićeni desmuramil-dipeptid, Boc-L-Ala-D-isoGln(OBn), kojem je najprije uklonjena benzilna esterska skupina s bočnog ogranka isoGln. Ferocenski alkoholi, pripremljeni na Prehrambeno-biotehnološkom fakultetu Sveučilišta u Zagrebu, sadrže alkilnu poveznicu s različitim brojem metilenskih skupina (n = 2, 4 i 5). Navedeni alkoholi u uvjetima Steglichove esterifikacije vezani su esterskom vezom na karboksilnu skupinu bočnog ogranka izoglutamina. Pripravljenim ferocenskim esterima desmuramil-dipeptida uklonjena je Boczaštitna skupina s amino-skupine alanina te su amidnom vezom vezani na karboksilnu skupinu benzilima zaštićene manozne podjedinice. U posljednjem sintetskom koraku uklonjene su zaštitne skupine s manoze, čime su dobivene ciljne molekule pogodne za ispitivanje in vitro adjuvatnog učinka.
Abstract (english)
In this diploma thesis, preparation of three ferrocene esters of mannosylated desmuramyldipeptide, L-alanyl-D-isoglutamine, is described. Using a convergent approach, fragments, a mannose subunit with a C2 spacer, a dipeptide and ferrocene alcohols were prepared separately, which were subsequently combined into one unit. Commercially available Boc-L-Ala-DisoGln-OBn was used as starting dipeptide. Ferrocene alcohols, that were prepared at the Faculty of Food Techology and Biotechnology, University of Zagreb, contain an alkyl linker with a different number of methylene groups (n = 2, 4 and 5). The alcohols are bound by an ester bond under the conditions of Steglich esterification to the carboxyl group of isoglutamine side chain, which was previously deprotected. The prepared ferrocene esters of desmuramyldipeptide were additionally mannosylated by binding of the -amino group of alanine, which was previously deprotected, to the carboxyl group of the mannose subunit. The benzylprotected mannose subunit with a C2 spacer was prepared in two synthetic steps from 2,3,4,6- tetra-O-benzyl-α-D-mannopyranose. In the last step, protective groups were removed from mannose, which resulted in target molecules suitable for testing the in vitro adjuvant effect.
