Antimalarial agent 18, a powerful antimalarial compound characterized by its electronic, highly lipophilic, and siderophoric properties, falls within the acyloxymethyl series, acting as a fosmidomycin surrogate. It effectively inhibits the non-mevalonate isoprenoid biosynthesis pathway by targeting the IspC enzyme. This compound demonstrates significant inhibitory activity against P. falciparum (IC50 = 50 nM) and A. baumanii (IC50 = 390 nM).
