Chemical disarming of isoniazid resistance in Mycobacterium tuberculosis

  05 July 2019

Mycobacterium tuberculosis (Mtb) causes the disease tuberculosis (TB), which kills more people than any other infection. The emergence of drug-resistant Mtb strains has exacerbated this already alarming epidemic. The authors have identified a small molecule, C10, that potentiates the activity of the frontline antibiotic isoniazid (INH) and prevents the selection for INH-resistant mutants. They find that C10 can even reverse INH resistance in Mtb. Therefore, our study reveals vulnerabilities that can be exploited to reverse INH resistance in Mtb.
