ABSTRACT
To expand the structure-activity relationships of fosmidomycin and FR900098, two potent antimalarials interfering with the MEP-pathway, we decided to replace a methylene group in beta-position of the phosphonate moiety of these leads by an oxygen atom. beta-oxa-FR900098 (11) proved equally active as the parent compound. When applied to 4-[hydroxyl(methyl)amino]-4-oxobutyl phosphonic acid, featuring a hydroxamate instead of the retrohydroxamate moiety, a beta-oxa modification yielded a derivative (13) with superior activity against the Plasmodium falciparum 3D7 strain than fosmidomycin, while a gamma-oxa modification resulted in less active derivatives. A bis(pivaloyloxymethyl)ester of phosphonate 13 proved twice as active in inhibiting cultured parasites as a similar prodrug of FR900098.
