MK-571 has been reported to be a selective competitive inhibitor of [3H]leukrotriene D4 (LTD4) binding to CysLT1 receptors. LTD4 may act to induce contractions in guinea pig trachea and human lung membranes. This compound demonstrates inhibitory characteristics of Mdr-1 (multidrug resistance protein-1) mediated transport. Additionally, studies suggest that this agent can augment the effects of cytotoxic agents on cells in vitro. MK-571 is an inhibitor of MRP1 and CysLT1 Receptor. The extensive utilization of MK-571 in scientific research studies can be attributed to its remarkable ability to hinder the activity of leukotriene D4. MK-571 is primarily explored in research focused on its function as a leukotriene receptor antagonist. It facilitates the study of leukotriene pathways, which are for understanding inflammatory processes.
