5,8,11-Eicosatriynoic Acid is a selective inhibitor of lipoxygenases with ID50 values of 24 μM and 340 μM for n-8 lipoxygenase and fatty acid cycle-oxygenase , respectively[1][2].
Fatty acid cycle-oxygenase and n-8 lipoxygenase catalyze the initial reactions which lead to the formation of three major arachidonic acid metabolites in human platelets. In several tissues, these two enzymes act concomitantly on arachidonic acid [1].
5,8,11-Eicosatriynoic Acid (5,8,11-ET) is a selective inhibitor of lipoxygenases with ID50 values of 24 μM and 340 μM for n-8 lipoxygenase and fatty acid cycle-oxygenase, respectively. 5,8,11-Eicosatriynoic acid was useful for studies on physiological and pathophysiological roles of 12 L-hydroxy-5,8,10,14-eicosatetraenoic acid formation in various tissues [1]. In mouse mastocytoma cells, 5,8,11-Eicosatriynoic Acid inhibited A23187 and L-cysteine induced leukotriene C (LTC4) biosynthesis with ID50 value of 5 μM [2].

General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
