| Bioactivity | TBAJ-587, a potent anti-tuberculosis agent, inhibits M.tb strain H37Rv growth with MIC90s of 0.006 and <0.02 µg/mL in MABA and LORA assay, respectively. TBAJ-587 inhibits hERG channel minimally, attenuates inhibition of the cardiac potassium channel protein coded by the hERG, which is important for cardiac repolarization[1]. | ||||||||||||
| Target | Anti-tuberculosis | ||||||||||||
| Invitro | Bedaquiline is a drug of the diarylquinoline class that has proven to be clinically effective against drug-resistant tuberculosis, but has a cardiac liability due to its potent inhibition of the cardiac potassium channel protein hERG. TBAJ-587, an analogue of Bedaquiline, demonstrates more potent anti-tubercular activity, with greatly attenuated hERG blockade. TBAJ-587 inhibits hERG channel with an IC50 of 13 μM[1]. | ||||||||||||
