OBJECTIVES As an initial step in developing novel antibacterials against Burkholderia pseudomallei, we have characterized the FabI enoyl-ACP reductase homologues in the type II fatty acid biosynthesis pathway from this organism and performed an initial enzyme inhibition study. METHODS A BLAST analysis identified two FabI enoyl-ACP reductase homologues,(More)
The bacterial fatty acid biosynthesis pathway is a validated target for the development of novel chemotherapeutics. However, since Burkholderia pseudomallei carries genes that encode both FabI and FabV enoyl-acyl carrier protein (ACP) reductase homologues, the enoyl-ACP reductase that is essential for in vivo growth needs to be defined so that the correct(More)
Francisella tularensis is classified as a category A priority pathogen and causes fatal disseminated disease in humans upon inhalation of less than 50 bacteria. Although drugs are available for treatment, they are not ideal because of toxicity and route of delivery, and in some cases patients relapse upon withdrawal. We have an ongoing program to develop(More)
Much is known about the mode of action of drugs and resistance mechanisms under laboratory growth conditions, but research on the bacterial transcriptional response to drug pressure in vivo or efficacious mode of action and transient resistance mechanisms of clinically employed drugs is limited. Accordingly, to assess active alternative metabolism and(More)
Melioidosis is caused by the facultative intracellular bacterium Burkholderia pseudomallei and is potentially fatal. Despite a growing global burden and high fatality rate, little is known about the disease. Recent studies demonstrate that cyclooxygenase-2 (COX-2) inhibition is an effective post-exposure therapeutic for pulmonary melioidosis, which works by(More)
