Verlukast, also known as MK-0679, is a (R)-enantiomer of MK-571 and a potent and selective LTD4 receptor antagonist. Verlukast showed [3H]leukotriene D4 binding in guinea-pig (IC50 = 3.1 +/- 0.5 nM) and human (IC50 = 8.0 +/- 3.0 nM) lung homogenates and dimethyl sulfoxide differentiated U937 cell membrane preparations (IC50 = 10.7 +/- 1.6 nM) but is essentially inactive versus [3H]leukotriene C4 binding in guinea-pig lung homogenates (IC50 values of 19 and 33 microM). Verlukast was in clinical development for the treatment of asthma and related diseases. (last updated: 8/8/2016)
