Biologische Aktivität
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].
