Pneumocystis jirovecii pneumonia detection and treatment

In an effort to develop new and more potent therapies to treat tuberculosis, a library of compounds was screened for M. tuberculosis UDP-Gal mutase inhibition. Nitrofuranylamide 1 was identified as a hit in this screen, possessing good antituberculosis activity. This paper describes the synthesis and evaluation of an expanded set of nitrofuranylamides. We have discovered a number of nitrofuranylamides with submicromolar M. tuberculosis MIC values and acceptable therapeutic indexes. The MIC activity did not correlate with UDP-Gal mutase inhibition, suggesting an alternative primary cellular target was responsible for the antituberculosis activity. The compounds were only active against mycobacteria of the tuberculosis complex. On the basis of these results, four compounds were selected for in vivo testing in a mouse model of tuberculosis infection, and of these compounds one showed significant antituberculosis activity.
