產(chǎn)品描述：

A438079 is a selective small-molecule antagonist of human P2X7 receptor with IC50 value of 300 nM [1].

The nucleotide receptor P2X7 receptor is a subtype of the P2X receptor family. It is expressed in cells of both the central nervous system and the immune system. Since the activation of P2X7 receptor by ATP is associated with the release of glutamate and cytokines, P2X7 receptor is thought to be a target of the treatment for inflammation and neurodegeneration. The tetrazole-based compound A438079 works as a competitive antagonist of P2X7 receptor and shows potent antinociceptive activity in rat model [2].

A 438079 was selective against P2X7 receptor and showed no significant activity against other P2X receptors including P2X2, P2X3 and P2X4 even at concentration up to 10 μM. For other cell-surface ion channels and receptors, A 438079 also showed no effect. In the FLIPR assay using human 1321N1 astrocytoma cells stably transfected with recombinant rat or human P2X7 receptors, pretreatment of A 438079 potently inhibited the calcium influx with IC50 values of 100 and 300 nM, respectively. In human THP-1 cells differentiated with IFNγ and LPS, A 438079 treatment inhibited interleukin-1β release stimulated by BzATP with pIC50 value of 6.7.Besides that, A 438079 was found to block the pore formation in humanTHP-1 cells [1 and 2].

In the rat model of neuropathic pain, administration of A 438079dose-dependently reduced the mechanical allodynia with ED50 value of 76 μM/kg. In mice with status epilepticus, administration of A 438079 resulted in decreased total seizure power, amplitude and reduced seizure behavior. In addition, A 438079 was found to attenuate acetaminophen-induced liver injury in mice [2, 3 and 4].
