Biochem/physiol Actions

Delamanid (OPC-67683) is an orally active mycolic acid biosynthesis inhibitor that is effective against both drug-susceptible and drug-resistant strains of M. tuberculosis H37Rv in vitro (MIC = 6 ng/mL) and exhibits significant in vivo efficacy with ~15-fold higher potency than rifampicin (RFP) in mice infected with M. tuberculosis Kurono (fold of lung CFU reduction post 28 days = 41.5 with 5 mg RFP/kg or 0.313 mg delamanid/kg daily orally dosage, 11,000-fold reduction with 0.625 mg delamanid/kg daily orally dosage).

In an effort to develop potent new antituberculosis agents that would be effective against both drug-susceptible and drug-resistant strains of Mycobacterium tuberculosis, we prepared a novel series of optically active 6-nitro-2,3-dihydroimidazo[2,1-b]oxazoles substituted at the 2-position with various phenoxymethyl groups and
