Background:

AM679 is a topically applied and potent 5-lipoxygenase-activating protein (FLAP) inhibitor with an IC50 value of 2.2 nM [1] [2].


FLAP and 5-lipoxygenase (5-LO) together convert membrane-derived arachidonic acid to the pro-inflammatory mediator leukotriene epoxide LTA4. LTA4 is hence rapidly converted into either LTB4 by LTA4 hydrolase or LTC4 by LTC4 synthase [2].


Incubation with AM679 for an extended time period (5 h) increased the potency of human blood against LTB4 production with an IC50 value of 53 nM. This time-dependent increase also happened with an IC50 value of 9 nM in rat blood incubated with AM679 for 4 h [2].


Cysteinyl leukotrienes (CysLTs) are known as promoters of inflammation and allergy. Mouse eye infected by RSV began to show increased ocular CysLTs 4 days after infection. AM679 decreased the peak 6- to 8-day of ocular CysLTs by more than 90%. By day 10, concentrations of CysLT for both AM679-treated mouse eyes and control had almost returned to the baseline. A strong correlation between RSV and IL-4 mRNA had been found for human allergic conjunctivitis. 6 days after RSV infection, IL-4 mRNA concentrations were significantly elevated in RSV-infected mouse eyes. Around 14 days, IL-4 mRNA concentrations were hence gradually decreased to near baseline. AM679 could inhibit more than 80% of the IL-4 increase resulted from RSV infection [1].
