Description
OverviewA cell-permeable benzothiazolylthiophene that exhibits bactericidal activity against mycobacteria, including M. smegmatis, M. bovis GCG, and M. tuberculosis (MIC50 = 30, 40, and 10 ng/mL, respectively, in biofilm medium; MIC50 = 4.5, 3, 0.19 µg/mL, respectively, in 7H9 medium), but not E. coli, Staphylococcus aureus, or Pseudomonas aeruginosa, by simultaneously targeting DprE1 FAD-binding domain of DprE1/DprE2 required for Mycobacterium cell wall arabinan biosynthesis and the Mtb MoeW protein involved in the biosynthesis of MoCo, molybdenum cofactor indispensable for nitrate assimilation via MoCo-dependent enzymes. Either alone or used in combination, TCA1 is shown to greatly complement INH (Isoniazid) and RIF (Rifampicin) against both wt and drug-resistant Mtb cultures in vitro (1-7.5 µg/mL) and in treating acute and chronic Mtb H37Rv infections in mice in vivo (10-100 mg/kg p.o.) with no apparent host toxicity.

Either alone or used in combination, TCA1 is shown to greatly complement INH (Isoniazid) and RIF (Rifampicin) against both wt and drug-resistant Mtb cultures in vitro (3.75-7.5 µg/mL, 1 µg/mL, and 2 µg/mL, respectively), including the XDR (extensively drug resistant) TF275 (strain# mc28013) that is resistant to 10 TB drugs, and in treating acute and chronic Mtb H37Rv infections in mice in vivo (40-100 mg/kg, 25 mg/kg, and 10 mg/kg, respectively; p.o.). TCA1 exhibits no host toxicity (≥25 µM in cultures and 100 mg/kg in mice) and no activity toward hERG or four CTP enzymes.
