MK591(Quiflapon sodium) is a selective and specific 5-Lipoxygenase-activating protein (FLAP) inhibitor.

(S)-BI 665915 is an orally active oxadiazole-containing 5-lipoxygenase-activating protein (FLAP) inhibitor with an IC50 of 1.7 nM for FLAP binding. (S)-BI 665915 inhibits FLAP functional in human whole blood with an IC50 of 45 nM. (S)-BI 665915 demonstrates an excellent cross-species drug metabolism and pharmacokinetics (DMPK) profile and a dose-dependent inhibition of LTB4 production.

Veliflapon (BAY X 1005; DG-031) is an orally active and selective 5-lipoxygenase activating protein (FLAP) inhibitor. Veliflapon inhibits the synthesis of the leukotrienes B4 and C4.

A potent, selective FLAP inhibitor with binding IC50 of 2.6 nM; inhibits LTB4 synthesis following ionophore challenge in human whole blood with IC50 of 76 nM (5 h incubation); shows good selectivity over CYP3A4, 2C9, and 2D6; exhibits excellent preclinical toxicology, pharmacokinetics and oral bioactivity.
