Proteome of Mycobacterium tuberculosis treated with 2,4-disubstituted pyridine derivatives

Two selected compounds, 2,4-disubstituted pyridine derivatives (11 and 15), revealed significant bactericidal activity against Mycobacterium tuberculosis deposited within human macrophages as well as against biofilm-forming tubercle bacilli. The mass spectrometry-based proteomics (LC-MS/MS) of the wild-type tubercle bacilli growing in the subinhibitory concentration of 11 or 15 revealed 15 overproduced proteins not detectable in the control cells including virulence-related proteins.
