Pranlukast-d4 is intended for use as an internal standard for the quantification of pranlukast by GC- or LC-MS. Pranlukast is an orally bioavailable cysteinyl leukotriene 1 (CysLT1) receptor antagonist (IC50s = 4.3-7.2 nM in radioligand binding assays).1 It is selective for the CysLT1 receptor over the CysLT2 receptor (IC50 = 3,620 nM for the human receptor).2 Pranlukast inhibits mucus secretion induced by leukotriene D4 in isolated guinea pig trachea with an IC50 value of 0.3 μM.3 It inhibits TNF-α-induced NF-•B p65 nuclear localization in U937 and Jurkat cells when used at concentrations of 10 and 100 μM.4 Pranlukast inhibits bronchoconstriction induced by LTC4 , LTD4, and LTE4 , but not LTB4 , in guinea pigs (ID50s = 0.8, 1, 0.7, and >500 μg/kg, respectively).5 It reduces cortical infarct volume by 81.6% and decreases neuronal death in the cortex, hippocampus, and striatum in a rat model of ischemia induced by middle cerebral artery occlusion (MCAO) when administered at a dose of 0.03 mg/kg.6

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.
