Zafirlukast

别名

N-[3-[[2-Methoxy-4-[[[(2-methylphenyl)sulfonyl]amino]carbonyl]phenyl]methyl]-1-methyl-1H-indol-5-yl]carbamic acid cyclopentyl ester

应用

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

生化/生理作用

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.
