Product Data
Biological target:
Selective, high affinity P2X3 and P2X2/3 antagonist.
In vitro activity:
TBD
In vivo activity:
P2X3 agonist-activated currents in the DRG neurons were recorded by whole cell patch clamp. The experimental results revealed that the P2X3 agonist α,βme-ATP (10 μM)-activated currents in DRG neurons cultured with gp120 were higher than those in controls (Fig. 4A). The inhibitory effect of A317491 on α,βme-ATP-induced currents in DRG rat neurons cultured with gp120 was larger than that for control (Fig. 4B) (n = 8, p < 0.01). These results further support the opinion that the activation of P2X3 receptor may be involved in HIV-associated neuropathic pain.
