Fosmidomycin is an antibiotic that was originally isolated from culture broths of bacteria of the genus Streptomyces.[1] It specifically inhibits DXP reductoisomerase, a key enzyme in the non-mevalonate pathway of isoprenoid biosynthesis. It is a structural analogue of 2-C-methyl-D-erythrose 4-phosphate. It inhibits the E. coli enzyme with a KI value of 38 nM (4), MTB at 80 nM, and the Francisella enzyme at 99 nM.[2]

Use in malaria[edit]

The discovery of the non-mevalonate pathway in malaria parasites has indicated the use of fosmidomycin and other such inhibitors as antimalarial drugs.[3] Indeed, fosmidomycin has been tested in combination treatment with clindamycin for treatment of malaria with favorable results.[4][5][6] It has been shown that an increase in copy number of the target enzyme (DXP reductoisomerase) correlates with in vitro fosmidomycin resistance in the lethal malaria parasite, Plasmodium falciparum.[7]
