Abstract
Novel nucleoside-Cinchona alkaloid conjugates were synthesized using 'click' chemistry approach based on the copper(I) catalyzed Huisgen azide-alkyne cycloaddition. Two series of conjugates were prepared employing 3'-azido-3'-deoxythymidine (AZT) as the azide component and the four 10,11-didehydro Cinchona alkaloids as well as their 9-O-propargyl ethers as the alkyne components. All obtained conjugates showed strong fluorescence emission and some of them exhibited marked cytotoxic activity in vitro.
