Biological Activity

a 804598 is a potent and selective antagonist of p2x7 receptor with ic50 values of 8.9, 9.9 and 10.9 nm for mouse, rat and human p2x7 receptors, respectively [1].p2x purinoceptor 7 (p2x7 receptor) is a purinoceptor and is activated by high concentrations of atp. p2x7 receptor plays an important role in atp-mediated cell death, inflammation and regulation of receptor trafficking.a 804598 is a potent and selective p2x7 receptor antagonist. in differentiated thp-1 cells that expressed human p2x7 receptors, a 804598 inhibited bzatp stimulated yo-pro uptake and release of il-1β. in 1321n1 cells expressed recombinant rat p2x7 receptor, a 804598 showed high affinity with kd = 2.4 nm [1]. a 804598 inhibited bz-atp stimulated calcium influx with ic50 value of 28.71 nm in a concentration-dependent way. a-804598 was a potent p2x7 receptor antagonist with ki value of 7.51 nm [2].in adult male rats, footshock increased the mrna levels of cd14 and il-1β in the paraventricular nucleus. while a-804598 (25 mg/kg) partially inhibited these effects [3].
