fr-900098

FR900098 is a derivative of fosmidomycin that has antimalarial activity (IC50s = 170, 170, and 90 nM for HB3, A2, and Dd2 P. falciparum strains, respectively). FR900098 inhibits DOXP reductoisomerase, a key enzyme in the non-mevalonate pathway of isoprenoid biosynthesis, in vitro in a dose-dependent manner. FR900098 (>10 mg/kg, i.p.) eradicated P. vinckei parasites within four days in mice.

FR900098 is an antimalarial agent that inhibits 1-deoxy-D-xylulose-5-phosphate (DXP) reductoisomerase. It exhibits no significant acute toxicity or genotoxicity and does not have the capability to cause chromosomal breaks or heterogeneity. Additionally, FR900098 has no impact on the bone marrow erythrocytes of NMRI mice.
