Description

General description

Oxidized ATP (oATP) is a Schiff-base-forming reagent is utilized as an antagonist at the P2X7 receptor for several years. It was initially identified as an affinity reagent for nucleotide-binding proteins. oATP reduces nuclear factor kappa B (NF-κB) activation and IL-8 release in cells lacking P2X7R, suggesting that some anti-inflammatory effects of oATP may not be solely attributed to the blockade of the P2X7R. This effect of oATP is reminiscent of the action of other natural or synthetic Schiff-base-forming reagents with immunomodulatory activity.

Application

Oxidized ATP (oATP) may be used to study its effects on the proinflammatory responses in human umbilical vein endothelial cells (HUVEC), HEK293 cells, and 1321N1 astrocytes that lack expression of P2X7R.
