AIP-II
Based on 1 Customer Validation
AIP-II is a cyclic peptide signaling molecule for quorum sensing, which is produced by Staphylococcus aureus. AIP-II potently inhibits AgrC-III in Methicillin (HY-121544)-resistant type III Staphylococcus aureus strain AH1747, with an IC50 of 0.532 nM. AIP-II binds to the AgrC-II receptor and regulates virulence gene expression in Staphylococcus aureus.

Biological Activity
t-AIP-II, a truncated analog of AIP-II, serves as an excellent template for the development of simplified peptidomimetic inhibitors, and it is also a potent pan-group inhibitor[1].
