In an ongoing effort to develop new and potent antituberculosis agents, a second-generation series of nitrofuranyl amides was synthesized on the basis of the lead compound 5-nitrofuran-2-carboxylic acid 3,4-dimethoxybenzylamide. The primary design consideration was to improve the solubility and consequently
