HIDE SMILES / InChI
MK-571 is a selective, orally active leukotriene D4/E4 (LTD4/E4) receptor antagonist patented by Merck Frosst Canada, Inc. for the treatment bronchoconstriction. In ex vivo models MK-571 competitively antagonizes contractions of guinea pig trachea and ileum induced by leukotriene (LT) D4 and LTE4 and contractions of human trachea induced by LTD4. MK-571 antagonizes bronchoconstriction induced in anesthetized guinea pigs by i.v. LTC4, LTD4, and LTE4 but do not block bronchoconstriction to arachidonic acid. In clinical trials, MK-571 is a potent antagonist of LTD4-induced bronchoconstriction in both normal volunteers and asthmatic patients.
