生物活性 | QStatin is a potent and selective inhibitor of SmcR (V. harveyi LuxR homologue) with an EC50 of 208.9 nM, binding tightly to SmcR and changes the flexibility of the protein, thereby altering its transcription regulatory activity. QStatin shows pan-QS (Vibrio quorum sensing) inhibitor activity in diverse Vibrio species and attenuates their virulence in an aquatic host. QStatin may be a sustainable antivibriosis agent useful in aquacultures. | ||||||||||||||||
体外研究 |
QStatin (0.001 μM-10 μM; 5 hours) inhibits SmcR activity measured by the RLU level for V. vulnificusWT (pBB1), reveals EC50 of 208.9 nM. QStatin (5 μM-50 μM; 16 hours) reduces the activities of SmcR-activated virulence factors (protease and elastase) in V. vulnificus in a dose dependent manner. QStatin (5 μM-50 μM; 16 hours) has no effect on the cellular levels of SmcR, indicating that QStatin does not affect the expression or stability of SmcR. 西域 has not independently confirmed the accuracy of these methods.
