Abstract

A series of N-benzylated phosphoramidate esters, containing a 3,4-dihydroxyphenyl Mg <superscript>2+</superscript> -chelating group, has been synthesised in five steps as analogues of fosmidomycin, a Plasmodium falciparum 1-deoxy-1-d-xylulose-5-phosphate reductoisomerase (PfDXR) inhibitor. The 3,4-dihydroxyphenyl group effectively replaces the Mg <superscript>2+</superscript> -chelating hydroxamic acid group in fosmidomycin. The compounds showed very encouraging anti-parasitic activity with IC <subscript>50</subscript> values of 5.6-16.4 µM against Plasmodium falciparum parasites and IC <subscript>50</subscript> values of 5.2 - 10.2 µM against Trypanosoma brucei brucei (T.b.brucei). Data obtained from in silico docking of the ligands in the PfDXR receptor cavity (3AU9) <superscript>5</superscript> support their potential as PfDXR inhibitors.<br /> (Copyright © 2020.
