A series of N-(2-phenoxy)ethyl imidazo[1,2-a]pyridine-3-carboxamides (IPAs), based on the structure of WZY02 discovered in our lab, were designed and synthesized as new anti-TB agents. Results reveal that many of them exhibit excellent in vitro inhibitory activity with low nanomolar MIC values against both drug-sensitive MTB strain H37Rv and drug-resistant clinical isolates. Compounds 15b and 15d display good safety and pharmacokinetic profiles, suggesting their promising potential to be lead compounds for future antitubercular drug discovery.

A set of 14 imidazo[1,2-a]pyridine-3-carboxamides was synthesized and screened against Mycobacterium tuberculosis H37Rv. The minimum inhibitory concentrations of 12 of these agents were ≤1 μM against replicating bacteria and 5 compounds (9, 12, 16, 17, and 18) had MIC values ≤0.006 μM. Compounds 13 and 18 were screened against a panel of MDR and XDR drug resistant clinical Mtb strains with the potency of 18 surpassing that of clinical candidate PA-824 by nearly 10-fold. The in vivo pharmacokinetics of compounds 13 and 18 were evaluated in male mice by oral (PO) and intravenous (IV) routes. These results indicate that readily synthesized imidazo[1,2-a]pyridine-3-carboxamides are an exciting new class of potent, selective anti-TB agents that merit additional development opportunities.
