Eight absence of compounds are in Phase antibiotics are in a position to meet all 4 criteria.

This Bedaquiline (marketed as Sirturo is, chemically, a diarylquinoline delamanid (2014). Bedaquiline (marketed as Sirturo) is, chemically, a diarylquinoline (Figure mechanism compound is an definitely innovative drug, since it presents an unprecedented 11) [56]. This of compound is an absolutely innovative pump as it presents an unprecedented mechanism action: It inhibits the ATPases proton drug, that supplies ATP towards the mycobacterium. of action: Itare necessary to determine whether the advantages of ATP for the mycobacterium.

Inside the 1990s, observed that Nitroimidazoles are heterocyclic nitro-derivatives. Inside the 1990s, it wasit was observed that metronidazole (5-nitroimidazole), belonging to this class, had moderate bactericidal metronidazole (5-nitroimidazole), belonging to this class, had moderate bactericidal acactivity against M. tuberculosis in anaerobic conditions. Subsequent research discovtivity against M. tuberculosis in anaerobic situations. Subsequent studies led to theled for the discovery of other nitroimidazoles, beginning with of formula of metronidazole, which ery of other nitroimidazoles, beginning with the formulathe metronidazole, which have been a lot more were extra productive against mycobacteria. The 2-nitroimidazole replaced in positions 1 effective against mycobacteria. The 2-nitroimidazole replaced in positions 1 and five have been and 5 nitroimidazolic compounds compounds with antitubercular They are at the moment the initial had been the very first nitroimidazolic with antitubercular activity [57].activity [57].
