12-oxo Leukotriene B4

Catalog No. T37256Cas No. 136696-10-1
Alias 12-Oxo-LTB4
12-oxo Leukotriene B4 (12-Oxo-LTB4) is a potent pro-inflammatory lipid mediator classified as a dihydroxy fatty acid that is enzymatically derived from arachidonic acid metabolism via the 5-lipoxygenase (5-LO) pathway, and it promotes a diverse array of leukocyte functional responses including cellular aggregation, stimulation of transmembrane ion fluxes, enhancement of lysosomal enzyme release, superoxide anion generation, chemotaxis, and chemokinesis; 12-oxo Leukotriene B4 is an initial oxidative metabolite formed from Leukotriene B4 via the LTB4 12-hydroxydehydrogenase pathway, which undergoes rapid enzymatic conversion first to 10,11-dihydro-12-oxo-LTB4 followed by reduction of the 12-oxo group to yield 10,11-dihydro-LTB4, and this metabolite exhibits significantly reduced biological potency, being approximately 70-fold less potent than LTB4 in stimulating Ca2+ mobilization in human neutrophils (EC50 = 33 nM vs. 0.46 nM) and also markedly less effective at stimulating neutrophil migration (EC50 = 170 nM vs. 2.7 nM).

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Stock Solution Preparation:
Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
Preparation of the In Vivo Formulation:
1) Add 100 μL of the DMSO stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
