Mechanism of action

Amelubant is a long-acting oral Leukotriene B4 (LTB4) receptor antagonist. Amelubant is a prodrug which is metabolized by ubiquitous esterases to BIIL 260 and its glucuronidated metabolite BIIL 315.14. BIIL 260 and BIIL 315.14 interact directly with the LTB4 receptors. LTB4 is a chemotactic factor for immune cells and potentiates the immune response. The G-protein coupled receptors BLT1, (high affinity for LTB4, expressed in most leukocytes) and BLT2 (low affinity for LTB4) are responsible for mediating LTB4's effects.
