Setileuton [MK-0633] is a selective inhibitor of the 5-lipoxygenase enzyme, which was under investigation for the treatment of asthma and atherosclerosis. Setileuton has been in phase II clinical trials by Merck Sharp & Dohme for the treatment of asthma, chronic obstructive pulmonary disease (COPD) and atherosclerosis. However, this research has been discontinued.

Sample Use Guides
This was a randomized, double-blind trial of once-daily Setileuton [MK-0633], 10 mg, 50 mg, and 100 mg, and placebo in patients 18-70 years with a history of chronic asthma, and FEV(1) ≥45 and ≤85% predicted. MK-0633 100 mg was significantly more effective than placebo for the change from baseline in FEV(1) (0.20 L vs. 0.13 L; p = 0.004).

In Vitro Use Guide
Curator's Comment: Setileuton [MK-0633] was evaluated for its potency to inhibit the oxidation of arachidonic acid by recombinant human 5-LO (H5-LO), and the production of LTB4 in calcium ionophore-stimulated HWB.
Setileuton [MK-0633] inhibited 5-LO activity with an IC50 of 3.9 nM in the H5-LO assay and production of LTB4 with IC50 of 52 nM in the HWB assay. This excellent 5-LO inhibitory profile is accompanied by a relatively low affinity for the hERG channel(Ki= 6.3 uM).
