NCIt definition : The fumarate salt form of bedaquiline, an orally bioavailable diarylquinoline antimycobacterial
agent, that can be used in the treatment of pulmonary multi-drug resistant tuberculosis
(MDR-TB). Upon oral administration, bedaquiline specifically binds to subunit c of
Mycobacterium tuberculosis (M. tuberculosis) adenosine 5'-triphosphate (ATP) synthase,
thereby preventing ATP synthase activity. This inhibits ATP synthesis in M. tuberculosis,
thereby blocking its energy metabolism and killing M. tuberculosis.;
