We report in this article an extensive structure-activity relationships (SAR) study with 58 thiophen-2-yl-1,2,4-oxadiazoles as inhibitors of EthR, a transcriptional regulator controling ethionamide bioactivation in Mycobacterium tuberculosis. We explored the replacement of two key fragments of the starting lead BDM31343.
