| Hazard Information | Back Directory | [Description]
MK-571 is a selective, orally active CysLT1 receptor antagonist. It blocks the binding of LTD4, but not LTC4, to human and guinea pig lung membranes with Ki values of 0.22 nM and 2.1 nM, respectively, which is indicative of CysLT1 receptor-mediated activity in these preparations. MK-571 effectively blocks LTD4 activation of recombinant human and murine CysLT1 receptors but is ineffective at blocking LTC4 or LTD4 activation of the recombinant human or murine CysLT2 receptors. | [Chemical Properties]
Yellow Solid | [Uses]
A receptor antagonist for the treatment of respiratory diseases. Cysteinyl leukotriene receptor antagonist MK-571 alters bronchoalveolar lavage fluid proteome in asthma | [Definition]
ChEBI: MK 571 is a member of quinolines. | [Biological Activity]
Potent CysLT 1 (LTD 4 ) leukotriene receptor inverse agonist (EC 50 = 1.3 nM). Antagonizes LTD 4 -induced contractions of guinea pig trachea and ileum (pA 2 values are 9.4 and 10.5 respectively). Also inhibitor of multidrug resistance protein-1 (MRP1) mediated transport; in vitro augments the effects of cytotoxic agents on malignant cells. | [storage]
Store at -20°C | [References]
