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 novel and efficient synthetic method leveraging microwave-assisted organic synthesis (MAOS) to prepare disubstituted imidazo[1,2-a]- pyridine-3-carboxylic acid esters (IPCEs) (3a-z), the key intermediates for a class of novel anti-tuberculosis agents, is reported. Under microwave heating at 120 °C for 20 or 30 min, the condensations of 2-aminopyridines (1a-k) and ethyl 2-halogenated acetoacetates (2a-d) were conveniently performed in ethanol with acceptable yields.
