Chemical disarming of isoniazid resistance in Mycobacterium tuberculosis
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.
