Antitubercular agent-56
Antitubercular agent-56, a Questiomycin A (HY-N8439) derivative, is a potent and orally active antitubercular agent. Antitubercular agent-56 disrupts mycobacterial envelope integrity by inhibiting FabD (Kd = 9.39 μM; IC50 = 49.60 μM). Antitubercular agent-56 exhibits good intracellular antimycobacterial activity against Mycobacterium tuberculosis (MTB) and drug-resistant MTB both in vitro and in vivo. Antitubercular agent-56 can be used for research on tuberculosis (TB).

Antitubercular agent-56 (compound B10) (7 days) exhibits potent antitubercular activity against MTB H37Rv (MIC = 0.15 μg/mL) and drug-sensitive and drug-resistant MTB strains with MIC range from 0.063 to 0.25 μg/mL)[1].
Antitubercular agent-56 (0.26-64 μg/mL, 48 h) exhibits low cytotoxicity against Vero, HepG2 and J774A.1 cells with IC50s of >128, >80, and >80 μg/mL, respectively[1].
Antitubercular agent-56 (1/2 × MIC-16 × MIC; 0-14 days) exhibits potent bactericidal efficacy against H37Rv MTB strain and clinical isolate in a concentration- and time-dependent manner[1].
Antitubercular agent-56 (1-4 μg/mL; 72 h) effectively penetrates macrophages and inhibits intracellular MTB growth[1].
Antitubercular agent-56 (4 × MIC; 30 min) significantly increases mycobacterial membrane permeability compared to control, confirming its disruptive effect on cell wall integrity[1].
