LasB-IN-3
Based on 1 Customer Validation
LasB-IN-3 is a protease elastase (LasB) inhibitor of Pseudomonas aeruginosa with an IC50 value of 8.5 nM. LasB-IN-3 shows an IC50 of 58.9 nM for the Met128Val mutant. LasB-IN-3 binds to active sites of wild-type and Met128Val mutant LasB, coordinates zinc ions, forms hydrogen bonds and CH-π interactions, and inhibits LasB proteolytic activity. LasB-IN-3 increases survival rate in LasB-induced acute lung injury mice models. LasB-IN-3 can be used for the research of Pseudomonas aeruginosa infection.

IC50 & Target
[1]|
LasB 8.5 nM (IC50) |
In Vitro
LasB-IN-3 (Compound 21) potently inhibits wild-type Pseudomonas aeruginosa LasB with an IC50 of 8.5 ± 0.5 nM, and its activity is reduced ~7-fold against the Met128Val variant (IC50 = 58.9 nM)[1].
LasB-IN-3 inhibits Pseudomonas aeruginosa LasB with an IC50 of 45 nM in the presence of porcine pulmonary surfactant, with reduced activity attributed to 37.2 ± 0.8% binding to surfactant proteins[1].
LasB-IN-3 (0-100 μMM) exhibits minimal cytotoxicity against human A549, HepG2, and HEK293 cell lines[1].
