  • Cyclodepsipeptide antibiotic. Unusual 12-membered macrocyclic depsipeptide comprises three unique subunits incorporating two substituted pyridines.
  • Potent antitubercular agent.
  • Inhibitor of NADH-dependent enoyl (Acyl-Carrier-Protein) reductase InhA, preventing mycolic acid synthesis in M. tuberculosis.
  • Shown to be active against isoniazid-resistant mycobacteria.
