P2X7 receptor antagonist-4

Compound 14a (P2X7 receptor antagonist-4) is a P2X7R antagonist with IC50 values of 64.7 nM in humans and 10.1 nM in mice. It inhibits the activation of the NLRP3 inflammasome, which subsequently reduces the expression of caspase-1, gasdermin D, IL-1β, and IL-18 in the kidneys of mice with sepsis-induced damage [1].
