Abstract
Vynález se týká kyseliny hyaluronové znacené tritiem a zpusobu její prípravy. Postup je zalozen na oxidacne-redukcní strategii, kde k oxidaci na aldehyd a redukci zpet na alkohol dochází v poloze 6-glukosaminové cásti polysacharidu. Výsledkem je nativní derivát o molekulové hmotnosti v rozsahu 800 g.mol.sup.-1.n.az 1 000 000 g.mol.sup.-1.n.vykazující vysokou stabilitu a specifickou aktivitu, která je omezená jenom specifickou aktivitou pouzitého redukcního cinidla. Postup prípravy je rychlý, levný a produkuje minimum radioaktivního odpadu v podobe balastu. Znacená kyselina hyaluronová byla testována pri studiích biodistribuce u potkanu, kde byla overena její stabilita detekcí kyseliny hyaluronové po intravenózním podání v moci. Znacená kyselina hyaluronová se muze pouzít v biomedicínských aplikacích.
