Benzeneacetic acid, α-cyclopentyl-4-(2-quinolinylmethoxy)-, (αS)-

(S)-Veliflapon ((S)-BAY X 1005) is an orally active inhibitor of leukotriene biosynthesis and 5-lipoxygenase activating protein (FLAP). (S)-Veliflapon inhibits the formation of leukotriene B4 (LTB4) in rat, mouse and human leukocytes with IC50 values of 0.026 μM, 0.039 μM and 0.22 μM respectively. (S)-Veliflapon showes enantioselectivity in human whole blood[1][2][3].
