Pranlukast (C007B-247963)

InformationPranlukast Pranlukast (ONO-1078) 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.In vitroPranlukast 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. 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. 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.In vivoPranlukast 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.Cell Datacell lines：OocytesConcentrations：Incubation Time：Powder Purity:≥99%.
