Abstract

Chlamydia trachomatis is an obligate intracellular bacterium responsible for a number of health problems, including sexually transmitted infection in humans. We recently discovered that C. trachomatis infection in cell culture is highly susceptible to inhibitors of peptide deformylase, an enzyme that removes the N-formyl group from newly synthesized polypeptides. In this study, one of the deformylase inhibitors, GM6001, was tested for potential antichlamydial activity using a murine genital C. muridarum infection model. Topical application of GM6001 significantly reduced C. muridarum loading in BALB/c mice that were vaginally infected with the pathogen. In striking contrast, growth of the probiotic Lactobacillus plantarum is strongly resistant to the PDF inhibitor. GM6001 demonstrated no detectable toxicity against host cells. On the basis of these data and our previous observations, we conclude that further evaluation of PDF inhibitors for prevention and treatment of sexually transmitted chlamydial infection is warranted. © 2007 Elsevier GmbH.
