Application

Ethambutol is an antimycobacterial used to treat tuberculosis in combination with other antibiotics to reduce the development of drug resistance. It has been used to study multidrug-resistant tuberculosis (MDR-TB) in highest-incidence-rate areas in China.

Biochem/physiol Actions

Ethambutol is bacteriostatic against actively growing TB bacilli. Mycolic acids attach to the 5′-hydroxyl groups of D-arabinose residues of arabinogalactan and form mycolyl-arabinogalactan-peptidoglycan complex in the cell wall. Ethambutol disrupts arabinogalactan synthesis by inhibiting arabinosyltransferases, specifically those in Mycobacterium, interfering with the biosynthesis of arabinogalactans found in the cell wall of mycobacteria and leading to increased cell wall permeability.

To study the evolution of drug resistance, we genetically and biochemically characterized Mycobacterium tuberculosis strains selected in vitro for ethambutol resistance. Mutations in decaprenylphosphoryl-β-D-arabinose (DPA) biosynthetic and utilization pathway genes Rv3806c, Rv3792, embB and embC accumulated to produce a wide
