The current work characterizes a novel APN-targeted fluorescent probe （Bes-Green, 2） that manifests comparable inhibitory activity with Bestatin. This probe has capacity of tightly binding to the APN for imaging endogenous APN in living human ovarian clear cell carcinoma cells （ES-2） and has potential application in biological study of cellular APN.展开更多

The initiation of this infectious disease is ascribed to the formation of subgingival biofilms. These biofilms cause stimulation of myriad of chronic inflammatory reactions by the affected tissue. The Gram-negative anaerobe Porphyromonas gingivalis is commonly found as part of the microbiota of subgingival biofilms, and is involved in the occurrence of the disease. P. gingivalis possesses numerous virulence factors supporting its survival, regulating its communication with other species in the biofilm, degrading host tissues. Fusobacterium nucleatum is pivotal for formation of biofilm and promotes growth and invasion properties ofP. gingivalis. Bestatin is an aminopeptide inhibitor, produced by actinomycetes. It possesses antibacterial properties against P. gingivalis and F. nucleatum. The following review focuses on action of bestatin on the mentioned bacteria.展开更多
