Trojan Horse Strategy: How A Prodrug For Moxifloxacin Kills TB Persisters

When the TB drug moxifloxacin was masked as a prodrug form, the prodrug’s permeability into the bacteria improved significantly. Once inside the bacteria, the prodrug is activated by an enzyme leading to the generation of the active drug moxifloxacin within the bacteria. This strategy significantly enhanced the lethality against TB persisters, thus effectively reducing the population of persisters

Reprogramming Macrophages: A New Hope for Tuberculosis Therapy

Why does TB therapy take six-nine months, and why do some Mycobacterium tuberculosis inside macrophages survive antibiotics better than others? Rigorous experiments have now revealed that macrophage’s own metabolism and the host cell where the bacteria live play a key role in shaping drug tolerance
