摘要：

As a model system for designing new inhibitors of bacterial cell division, we studied the essential and highly conserved FtsZ GTPase from Pseudomonas aeruginosa. A collection of GTP analogues were prepared using the solid-phase parallel synthesis approach. The synthesized GTP analogues inhibited the GTPase activity of FtsZ with IC50 values between 450 mu M and 2.6 mM, and 5 compounds inhibited Staphylococcus aureus growth in a biological assay. The FtsZ spectrophotometric assay developed for screening of synthesized compounds is the first step in identification of antibacterials targeting the bacterial cell division essential proteins.
