LasB-IN-1
LasB-IN-1 (compound 5f) is a potent and orally active inhibitor of LasB (IC50 = 8.7 μM). LasB-IN-1 effectively attenuates elastase production and biofilm formation by P. aeruginosa while alleviating the inflammatory response through downregulating MAPK and NF-κB pathways. LasB-IN-1 is potential to be a novel anti-infective candidate against drug-resistant infections.

LasB-IN-1 (5-10 μM, 10 h) suppresses the expression of LasB (IC50 = 8.7 μM), the elastase biosynthesis (IC50 = 7.3 μM) and the formation of biofilms (IC50 = 7.4 μM) in a dose-dependent manner in P. aeruginosa PAO1 strains[1].
LasB-IN-1 (1.25-20 μM, 24 h) reveals no cytotoxic effect in RAW264.7 cell and Vero cell. LasB-IN-1 (50-100 μM, 24 h) shows a slight cytotoxic effect. LasB-IN-1 (0.625-10 μM, 4 h) exerts negligible hemolytic effects on mouse and human erythrocytes[1].
LasB-IN-1 (10 μM, 4, 6 h) effectively inhibits the migration of macrophages to the site of injury in zebrafish larvae[1].
LasB-IN-1 (0.625-10 μM, 27 h) inhibits the production of IL-1β, TNF-α, and IL-6 in LPS (1 μg/mL, 24 h) treated RAW264.7 cells. LasB-IN-1 (1.25-10 μM, 27 h) also inhibits the mRNA expression of COX-2, iNOS, IL-1β, TNF-α, and IL-6[1].
LasB-IN-1 (1.25-10 μM, 27 h) significantly inhibits the phosphorylation of NF-κB p65, IκBα, JNK and ERK of LPS (1 μg/mL, 24 h) treated RAW264.7 cells in a concentration-dependent manner[1].

Cell Line:RAW264.7 cell and Vero cell
-
Concentration:1.25, 2.5, 5, 10, 20, 50, 100 μM
-
Incubation Time:24 h
-
Result:Revealed no cytotoxic effect at concentrations of lower than 20 μM, a slight cytotoxic effect was observed at a concentration of 50 μM, indicating the noncytotoxicity at concentrations effective against virulence and biofilm formation.
LasB-IN-1 (1, 2 mg/kg, i.g., 4 h) significantly downregulates expression levels of IL-1β, TNF-α, and IL-6 as well as reduces mRNA expression of COX-2, iNOS, IL-1β, TNF-α, and IL-6 in mice [1].
LasB-IN-1 (2, 4 mg/kg, i.g., once for 7 d) shows no obvious adverse reactions [1].

Animal Model:eight-week-old BALB/c wild-type mice (male, 18–22 g ), established a ALI model by using LPS (P. aeruginosa)[1]
-
Dosage:1 and 2 mg/kg
-
Administration:intragastric (i.g.), after treatment for 4 h, intraperitoneal injection of LPS (20 mg/kg), sacrificed by cervical dislocation after a 6 h treatment
-
Result:Reduced myeloperoxidase (MPO) activity in mice compared with that in LPS-only mice, indicating the inhibition of neutrophil infiltration in mouse lung tissues.
Exhibited significantly downregulated expression levels of IL-1β, TNF-α, and IL-6, with a concentration-dependent response while significantly reduced mRNA expression of COX-2, iNOS, IL-1β, TNF-α, and IL-6 in mice compared with LPS-only mice.

-
Result:Exhibited no adverse effects such as vomiting or diarrhea, had a negligible impact on the body weight of mice, did not induce any significant damage or histopathological alterations in vital organs.
