A discovery of novel Mycobacterium tuberculosis pantothenate synthetase inhibitors based on the molecular mechanism of actinomycin D inhibition

Mycobacterium tuberculosis pantothenate synthetase is a potential anti-tuberculosis target, and a high-throughput screening system was previously developed to identify its inhibitors. Using a similar system, we screened a small library of compounds and identified actinomycin D (ActD) as a weak inhibitor of pantothenate synthetase. A new method was established to discover more effective inhibitors by determining the molecular mechanism of ActD inhibition followed by structure-based virtual screening.
