Virstatin is an inhibitor of the ToxT transcriptional regulator of V. cholerae, which regulates transcription of virulence factors that enable intestinal colonization. It inhibits ToxT dimerization and decreases expression of cholera toxin (CT) and toxin coregulated pilus (TCP) when used at a concentration of 50 μM but virstatin does not inhibit growth of V. cholerae at this concentration (MBCs = 600 and 1,200 μM for O395 and C6706 strains, respectively). Virstatin administration protects infant mice (5 to 6 days old) from intestinal colonization by ToxT-dependent V. cholerae but not from strains that colonize via non-ToxT-dependent mechanisms. Virstatin (100 μM) inhibits biofilm formation by A. baumannii by 38% under static conditions, which is at a lower concentration than that which inhibits growth (MIC = 1.6 mM). It decreases the motility of 60% of 30 mobile A. baumannii strains. Virstatin also binds to the accessory cholera enterotoxin (Ace) from V. cholerae (Ka = 9 x 104 M-1; Kd = 11 uM).

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
