AI Article Synopsis
- * Several compounds, including racemic gossypol, enantiopure gossypol (AT-101), oxamate, galloflavin, and stiripentol, showed a dose-dependent reduction in bacterial growth.
- * Notably, racemic gossypol and AT-101 completely halted the growth of the bacteria at specific concentrations, suggesting that the specific form of gossypol used may significantly impact its effectiveness as an LD
Article Abstract
, the causative agent of Lyme disease, has a highly reduced genome and relies heavily on glycolysis for carbon metabolism. As such, established inhibitors of lactate dehydrogenase (LDH) were evaluated in cultures to determine the extent of their impacts on growth. Both racemic and enantiopure (AT-101) gossypol, as well as oxamate, galloflavin, and stiripentol, caused the dose-dependent suppression of growth in vitro. Racemic gossypol and AT-101 were shown to fully inhibit spirochetal growth at concentrations of 70.5 and 187.5 μM, respectively. Differences between racemic gossypol and AT-101 efficacy may indicate that the dextrorotatory enantiomer of gossypol is a more effective inhibitor of growth than the levorotatory enantiomer. As a whole, LDH inhibition appears to be a promising mechanism for suppressing growth, particularly with bulky LDH inhibitors like gossypol.
