E216-5303 | restores yeast growth after treatment with ExoS | Pseudomonas aeruginosa | |
everninic acid | restores yeast growth after treatment with ExoS | Pseudomonas aeruginosa | |
exosin | a small molecule inhibitor, that modulates ExoS ADP-ribosyltransferase activity in vitro, suggesting the inhibition is direct. Exosin and two of its analogues display a significant protective effect against Pseudomonas infection in vivo, competitive against NAD+ | Pseudomonas aeruginosa | |
