General description

A potent, competitive, and selective antagonist of P2X7 purinergic receptor (pIC50 = 6.5 nM and 6.9 nM for rat and human P2X7 receptor, respectively). Shown to reduce ATP-induced reactive oxygen species formation in MEL cells by about 87% (~10 µM) and blocks BzATP-stimulated changes in intracellular calcium concentrations (IC50 = 100 and 300 nM at rat and human P2X7 receptors, respectively.

The presence of P2X7 on erythroid cells is well established, but its physiological role remains unclear. The current study aimed to determine if P2X7 activation induces reactive oxygen species (ROS) formation in murine erythroleukaemia (MEL) cells, a commonly used erythroid

ATP-sensitive P2X(7) receptors are localized on cells of immunological origin including peripheral macrophages and glial cells in the CNS. Activation of P2X(7) receptors leads to rapid changes in intracellular calcium concentrations, release of the proinflammatory cytokine interleukin-1beta and following prolonged
