Background:

BIIL-260 hydrochloride is a potent and long-acting orally active leukotriene B(4) receptor LTB4 antagonist, with anti-inflammatory activity. BIIL-260 hydrochloride interacts with the LTB4 receptor in a saturable, reversible, and competitive manner, has high affinity to the LTB4 receptor on isolated human neutrophil cell membranes with Ki values of 1.7 nM[1]. Ki: 1.7 nM (LTB4 receptor)[1]

BIIL-260 hydrochloride potently inhibits LTB4-induced intracellular Ca2+ release in human neutrophils with IC50 value of 0.82 nM
