Description Pranlukast (ONO-1078,ono-rs-411) is an orally administered, and selective antagonist of the cysteinyl leukotrienes (LT) C(4), LTD(4) and LTE(4), used in the prophylactic treatment of chronic bronchial asthma.

Pranlukast inhibits NF-kappa B activation in 1.3% DMSO-differentiated U-937 and Jurkat cells by about 40% & 30%, respectively. Pranlukast and MK-571 inhibit NF-kappa B activation in 1.3% DMSO-differentiated U-937 and Jurkat cells in a dose-related manner. Pranlukast and MK-571 inhibits LPS-induced IL-6 production in PBMC by about 65% and 15%, respectively. [1] Pranlukast or zafirlukast significantly inhibits 10 mM LTD4-evoked 35SO4 output in a concentration-dependent fashion, with maximal inhibitions of 83% at 10 mM Pranlukast and 78% at 10 mM Zafirlukast, and IC50 values of 0.3 mM for Pranlukast and 0.6 mM for Zafirlukast. Pranlukast (0.5 microM) causes a parallel rightward shift of the LTD4 concentration-response curve with a pKB of 7. Pranlukast or Zafirlukast (5 microM each) significantly suppresses ovalbumin-induced secretion in tracheae from sensitized guinea-pigs by 70% and 65%, respectively. [2] Pranlukast also inhibits NF-kappaB activation induced by phorbol 12-myristate 13-acetate (PMA). Pranlukast also significantly inhibits LPS-induced MUC2 mRNA expression by reverse transcription-polymerase chain reaction (RT-PCR) analysis in NCI-H292 cells. Pranlukast also inhibits LPS-induced MUC2 gene expression in HM3-MUC2 cells. [3]

Pranlukast significantly reduces lesion volume, and increases neuron densities in the cortex and hippocampal CA1 region in the ischemic hemispheres of mice. Pranlukast also remarkably reduces the thickness of a scar wall in the ischemic hemispheres of mice. [4]

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.
