Application

Zafirlukast has been used to stimulate pancreatic β cell line (MIN6) and pancreatic islets for insulin secretion assay. It may be used as an adenosine triphosphate-binding cassette transporter (ABCG2) inhibitor in MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] cytotoxicity assay in human embryonic kidney cells (HEK293) and in Kirby-Bauer disc diffusion assays, bactericidal activity and minimal inhibitory concentration (mIC) assay against M. smegmatis

Biochem/physiol Actions

Zafirlukast is a potent subtype specific cysteinyl leukotriene type 1 receptor (CysLT1) antagonist; antiasthmatic. Zafirlukast has over 1000-fold selectivity for CysLT1, one of two receptors for cysteinyl leukotrienes LTC4, LTD4, and LTE4, which are important mediators of human bronchial asthma.
Zafirlukast plays a key role in alleviating mucus and airway constriction in asthma based inflammatory response. It regulates pancreatic β cells for the secretion of insulin and this functionality is interlinked to the calcium based phosphorylation of the Ca2+/calmodulin-dependent protein kinase II (CaMKII) and protein kinase B (AKT). Zafirlukast has inhibitory potential on ATP-binding cassette (ABC) transporters and reverses the multidrug resistance function of ATP-binding cassette super-family G member 2 (ABCG2). Zafirlukast inhibits mycobacterial nucleoid-associated protein Lsr2 and halts the growth of Mycobacteria.

Cysteinyl leukotrienes (CysLTs) have been implicated in the pathophysiology of inflammatory and cardiovascular disorders. Their actions are mediated by CysLT(1) and CysLT(2) receptors. Here we report the discovery of 3-({[(1S,3S)-3-carboxycyclohexyl]amino}carbonyl)-4-(3-{4-[4-(cyclo-hexyloxy)butoxy]phenyl}propoxy) benzoic acid (HAMI3379), the first potent and selective CysLT(2) receptor

The mycobacterial nucleoid-associated protein Lsr2 is a DNA-bridging protein that plays a role in condensation and structural organization of the genome and acts as a global repressor of gene transcription. Here we describe experiments demonstrating that zafirlukast inhibits the complexation

Gemfibrozil, a strong inhibitor of cytochrome P450 (CYP) 2C8 in vivo, was recently found to markedly increase the plasma concentrations of montelukast in humans. Like montelukast, zafirlukast is a substrate of CYP2C9 and CYP3A4 and a potent inhibitor of CYP2C8

The zafirlukast has been reported to be anti-inflammatory and widely used to alleviate the symptoms of asthma. However, its influence on insulin secretion in pancreatic β-cells has not been investigated. Herein, we examined the effects of zafirlukast on insulin secretion
