BTZ043 Racemate (BTZ10526038) is the racemate of BTZ043. BTZ043 is an inhibitor of decaprenyl-phosphoribose-epimerase (DprE1), and the antimicrobial activity of BTZ043 is more potent than BTZ043 Racemate[1]. | [Biological Activity]
mic: 1 ng/ml (2.3 nm) for m. tuberculosis h37rv and 4 ng/ml (9.2 nm) for mycobacterium smegmatisthe loss of human lives to tuberculosis (tb) continues unabated as a result of poverty, synergy with the hiv/aids pandemic, and the emergence of multidrug- and extensively drug-resistant strains of mycobacterium tuberculosis. btz043 is the most advanced candidate for inclusion in combination therapies for both drug-sensitive and extensively drug-resistant tb. | [in vitro]
btz043 displayed similar activity against all clinical isolates of m. tuberculosis that were tested, including extensively drug-resistant and multidrug-resistant strains, indicating that it targets a previously unknown biological function. btz043 is bactericidal, reducing viability in vitro by more than 1000-fold in under 72 hours, which is comparable to the inh killing effect [1]. | [in vivo]
the in vivo efficacy of btz043 was assessed 4 weeks after a low-dose aerosol infection of in the chronic balb/c mice model of tb. four weeks of treatment with btz043 reduced the bacterial load in the lungs and spleens by 1 and 2 logs, respectively, at the concentrations used. additional findings suggest that btz efficacy is time- rather than dose-dependent [1]. | [target]
