TBA-7371
Based on 1 publication(s) in Google Scholar
TBA-7371 is an orally active and non-covalent inhibitor of Decaprenylphosphoryl-β-D-ribose oxidase (DprE1) of Mycobacterium tuberculosis (MIC=0.64 μg/mL). TBA-7371 can block the synthesis of arabinose in the bacterial cell wall, resulting in cell wall structural defects, thereby exerting an anti-tuberculosis effect. TBA-7371 can be used in the research of anti-tuberculosis drugs and has a synergistic bactericidal effect with Bedaquiline (HY-14881) and other drugs.

The MIC of TBA-7371 against Erdman and H37Rv strains of Mycobacterium tuberculosis is 1 μg/mL. In the presence of 4% human serum albumin, the MIC increases only 2-fold, indicating that binding to human serum albumin had little effect[2].
TBA-7371 (1, 10, 100 μg/mL; 14 days) shows dose-dependent bactericidal activity against Erdman strain of Mycobacterium tuberculosis, with the 100 μg/mL group showing the most significant bactericidal effect[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:Mycobacterium tuberculosis Erdman
-
Concentration:1 μg/mL, 10 μg/mL, 100 μg/mL
-
Incubation Time:14 days
-
Result:All concentrations significantly reduced bacterial CFU counts over 14 days compared to the DMSO control, with the 100 μg/ml group showing the highest bactericidal activity, demonstrating dose-dependent killing.
TBA-7371 (50, 100, 200 mg/kg; oral gavage; twice daily; 8 weeks) significantly reduces bacterial burden in lung tissue after 8 weeks of treatment in the C3HeB/Fe J mouse tuberculosis model[3].

-
Animal Model:Female BALB/c mice (5-6 weeks old, specific pathogen-free) + subacute tuberculosis infection model induced by aerosol of Mycobacterium tuberculosis H37Rv[3]
-
Dosage:100 mg/kg, 200 mg/kg (0.5% carboxymethylcellulose + 0.1% Tween 80)
-
Administration:Oral gavage, twice daily (8 h apart), 5 days/week for 4-8 weeks; Combination with Bedaquiline (25 mg/kg) and GSK2556286 (50 mg/kg) (BGA regimen)
-
Result:At 100 or 200 mg/kg bid significantly increased bactericidal activity after 8 weeks, with lung CFU counts of 1.48 (200 mg/kg) and 1.78 (100 mg/kg), demonstrating superior sterilizing activity compared to two-drug combinations.
-
Animal Model:Female C3HeB/FeJ mice (8-10 weeks old, specific pathogen-free) + chronic tuberculosis infection model with caseous necrotic pulmonary lesions induced by aerosol of Mycobacterium tuberculosis Erdman[3]
-
Dosage:50 mg/kg, 100 mg/kg, 200 mg/kg (0.5% carboxymethylcellulose + 0.1% Tween 80)
-
Administration:Oral gavage, twice daily, 5 days/week for 8 weeks
-
Result:After 8 weeks, all dose groups showed significant reduction in lung bacterial burden compared to untreated controls.
The 100 and 200 mg/kg groups achieved approximately 1.5 log CFU reduction, with dose-dependent efficacy.
At 100 mg/kg bid exhibited consistent bactericidal activity, with higher drug retention in caseous lesions at trough concentrations.
