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] Several mutations in the E. coli DXP reductoisomerase were found to confer resistance to fosmidomycin.[3][4]

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.[5] Indeed, fosmidomycin has been tested in combination treatment with clindamycin for treatment of malaria with favorable results.[6][7][8] 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.[9]
