AZ 11645373 (3-[1-[[(3'-NITRO[1,1'-BIPHENYL]-4-YL)OXY]METHYL]-3-(4-PYRIDINYL)PROPYL]-2,4-THIAZOLIDINEDIONE) 是一种高度选择性和有效的人 P2X7 受体拮抗剂，对小鼠/大鼠 P2X7 受体没有影响。

JNJ-54166060 是一种 有效的 P2X7 受体 (P2X7 receptor) 拮抗剂。JNJ-54166060 对人/大鼠/小鼠 P2X7 受体作用的 IC50值分别为 4/115/72 nM。

ITH15004 is a non-nucleotide antagonist of the purinergic P2X7receptor (IC50= 9 μM in HEK293 cells expressing the human receptor).1It inhibits ATP-induced currents inX. laevisoocytes expressing the human P2X7receptor when used at a concentration of 100 μM. ITH15004 (1 μM) decreases IL-1β release from LPS-primed, ATP-stimulated isolated mouse peritoneal macrophages. It has high permeability in a parallel artificial membrane permeability assay (PAMPA). 1.Calzaferri, F., Narros-Fernández, P., de Pascual, R., et al.Synthesis and pharmacological evaluation of novel non-nucleotide purine derivatives as P2X7 antagonists for the treatment of neuroinflammationJ.

P2X7 receptor antagonist-2 is a highly potent antagonist of the P2X7 receptor, exhibiting a pIC50 value range of 6.5-7.5. Its efficacy in combating neuroinflammation has been demonstrated [1].

GSK1370319A is a potent P2X7 antagonist (IC50 = 3.2 nM). GSK1370319A inhibits ATP-induced increase in IL-1β release and caspase 1 activation in lipopolysaccharide (LPS)-primed mixed glia by blocking assembly of the inflammasome in a pannexin 1-dependent manner. GSK1370319A also inhibits ATP-induced subregion-specific neuronal loss in hippocampal organotypic slice cultures, which is dependent on its ability to prevent inflammasome assembly in glia. Significantly, GSK1370319A attenuates age-related deficits in long-term potentiation (LTP) and inhibits the accompanying age-related caspase 1 activity. We conclude that inhibiting P2X(7) receptor-activated NLRP3 inflammasome formation and the consequent IL-1β release from glia preserve neuronal viability and synaptic activity.

EVT-401 (P2X7 receptor antagonist-1)，一种嘌呤能P2X7受体拮抗剂，具抗神经炎症作用。

P2X7 receptor antagonist-4（Compound 14a）是一种选择性P2X7R拮抗剂，其对人类和小鼠P2X7R的IC50值分别为64.7 nM和10.1 nM。该化合物能有效抑制NLRP3炎性体的激活，并在脓毒症模型小鼠中减少肾损伤，降低caspase-1、gasdermin D、IL-1β和IL-18的表达。
