Catalog No. T38373Cas No. 108985-27-9
Alias Pseudomonas Quinolone Signal, PQS, 2-heptyl-3-hydroxy-4(1H)-Quinolone

2-heptyl-3-hydroxy-4(1H)-Quinolone (Pseudomonas Quinolone Signal) is a quorum-sensing signalling molecule produced by Pseudomonas aeruginosa in response to increased cell density. It increases the expression of the lasB gene in P. aeruginosa, the secretion of the metabolites pyocyanin and the lectin PA-IL, as well as increasing biofilm production in P. aeruginosa populations. It also reduces the iron content of the P. aeruginosa growth medium when used at a concentration of 40 μM and acts as an iron chelator in iron sulphate solutions.

Description
2-heptyl-3-hydroxy-4(1H)-Quinolone (Pseudomonas Quinolone Signal) is a quorum-sensing signalling molecule produced by Pseudomonas aeruginosa in response to increased cell density. It increases the expression of the lasB gene in P. aeruginosa, the secretion of the metabolites pyocyanin and the lectin PA-IL, as well as increasing biofilm production in P. aeruginosa populations. It also reduces the iron content of the P. aeruginosa growth medium when used at a concentration of 40 μM and acts as an iron chelator in iron sulphate solutions.
In vitro
2-heptyl-3-hydroxy-4(1H)-Quinolone (60 µM) increases secretion of the metabolite pyocyanin and the lectin PA-IL, as well as increases biofilm production in P. aeruginosa populations.[2]
2-heptyl-3-hydroxy-4(1H)-Quinolone (40 µM) reduces iron levels in P. aeruginosa growth media when used at a concentration and acts as an iron chelator in a Fe(III)-sulfate solution.[3]

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% Saline/PBS/ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
All types of co-solvents required for the protocol, such asDMSO, PEG300/ PEG400, Tween 80, SBE-β-CD, corn oil are available for purchase on the TargetMol website with a simple click.
