Combination therapies exploring the synergistic effects of compounds with different modes of action have been widely used to treat infectious diseases.4 For example, -lactamase inhibitors such as clavulanic acid, sulbactam and tazobactam have been successfully combined with -lactam antibiotics to treat Gram-negative drug-resistant bacterial infections.5, Filamenting temperature-sensitive mutant Z (FtsZ), a prokaryotic homolog of mammalian -tubulin,6 is a self-activating guanosine triphosphatase (GTPase) that polymerizes into a highly dynamic cytoskeleton Z-ring at the site of septum formation.7,8 Given the essential role of FtsZ in the recruitment of downstream proteins for completion of bacterial cell division, FtsZ is an attractive target for the development of new antibacterial agents that has yet to be developed clinically.9, 10, 11, 12 A number of FtsZ inhibitors have been reported to impair the bacterial cell division, such as the small-molecule PC190723 that exhibits in vivo activity in a murine infection model system and restores the susceptibility of MRSA to -lactams.9, 10, 11, 12, 13, 14, 15, 16, 17 A recent report indicated that genetic depletion of FtsZ can cause the delocalization of penicillin-binding protein 2, the target of -lactam antibiotics, from the septum in S. aureus, resulting in the impairment of the assembly of bacterial cell wall.18. A Silent Operon of Photorhabdus luminescens Encodes a Prodrug Mimic of GTP. 21, 657679 (2011). Quinuclidine 1 (600M) and a mixture of 1 (600M) and ampicillin (600M) showed similar results to a control experiment with untreated mammalian tubulin, indicating that 1 is not an inhibitor of tubulin polymerization. S. aureus FtsZ (12M) in 50mM MOPS buffer (pH 6.5) was incubated with vehicle (1% DMSO) or different concentrations of the tested compound for 10min at 25C. The compound impaired the localization of FtsZ into the cytokinetic Z-ring by disruption of the assembly of FtsZ protein. Second, FtsZ acts as a potentially broad-spectrum antibacterial agent, capable of fighting polymicrobial infection and when the etiology of the infectious agent is unknown. Nam lacinia pulvinar tortor nec facilisis. This study showed that the activities of two -lactams (methicillin and imipenem) against MRSA were greatly enhanced by quinuclidine 1, while the activity of quinuclidine 1 itself was also improved. FtsZ assembles the cytoskeletal scaffold of the Z ring that, along with additional proteins, constricts to divide the cell in two. We have recently used a structure-based virtual screening approach to identify pyrimidine-linked quinuclidines as a novel class of FtsZ inhibitors. What do you think FtsZ inhibitor and imipenem are? B. Bacterial cytokinesis is directed by a ring composed of a protein called FtsZ. No spontaneous resistant mutant of MRSA was found in the presence of quinuclidine 1 alone or in combination with imipenem. I would wonder what would, happen if we used three antibiotics on the bacteria, and see if maybe some, antibiotics would cancel each other out. The grids were subsequently subjected to negative staining using 10l of 0.5% phosphotungstic acid for 30s, air-dried and digital images of the specimen were observed with a transmission electron microscope (JEOL model JEM 2010, Tokyo, Japan) operated at 200 kV and equipped with a Gatan MSC 794 CCD camera.17 Three independent experiments were performed for each test. 2004 Aug 10;101(32):11821-6. doi: 10.1073/pnas.0404439101. FtsZ inhibitor and Imipenem on their own are not highly effective as the number of colonies Susceptibility results showed that quinuclidine 1 was active against multiple antibiotic-resistant bacterial strains including methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus faecium with minimal inhibitory concentrations of 24gml1.
