Abstract

To explore the hitherto successful derivatization of the α-carbon of fosmidomycin, a series of new α-substituted analogues was prepared. This was done by introduction of a heteroatom (N or O) in α-position to the phosphonate and using the resultant OH and NH groups as a handle for appending a variety of substituents by means of several functional groups such as ether, amide, urea, and 1,4-triazole. The synthesized molecules, as a racemic mixture, were assayed for their EcDXR inhibitory potency. Both the α-azido-analogue and the α-hydroxylated analogue proved most promising, and docking experiments were performed. Although several compounds showed high potency when assayed against Plasmodium falciparum K1 in human erythrocytes, a clear correlation between the enzyme inhibition constants and P. falciparum inhibition concentrations could not be found.
