Tuberculosis (TB) is a highly infectious disease that has been plaguing the human race for centuries. The emergence of multidrug resistant strains of TB has been detrimental to the fight against tuberculosis with very few safe therapeutic options available. As part of an ongoing effort to identify potent anti-tuberculosis agents, we synthesized and screened a series of novel imidazo[1,2-a]pyridinecarboxamide derivatives for their anti-tuberculosis properties. These compounds were designed based on reported anti-tuberculosis properties of the indolecarboxamides (I2Cs) and imidazo[1,2-a]pyridinecarboxamides (IPAs). In this series, we identified compounds 15 and 16 with excellent anti-TB activity against H37Rv strain of tuberculosis (MIC = 0.10 – 0.19 μM); these compounds were further screened against selected clinical isolates of Mtb. Compounds 15 and 16 showed excellent activities against multidrug resistant (MDR) and extensively drug resistant (XDR) strains of TB (MIC range: 0.05 – 1.5 μM) with excellent selectivity indices. In addition, preliminary ADME studies on compound 16 showed favorable pharmacokinetic properties.This article is protected by copyright. All rights reserved.
