10Panx is a potent Panx1 channel inhibitor that targets the W74 to Y83 segment of the ECL1 of Panx1 protein [1]. 10Panx inhibits the P2X7 receptor activation-induced cleavage of caspase-1 and the processing and release of IL-1β by suppressing Panx1[2]. 10Panx has been widely used to alleviate the characteristic inflammatory responses in mouse models of asthma[3].
In vitro, 10Panx (50μM) treatment for 20 hours significantly inhibited the formation of capillary-like structures in human dermal lymphatic endothelial cells (HDLECs)[4]. Treatment with 10Panx at a concentration of 100μM for 6 hours delays the maturation of bovine oocytes and reduces the level of reactive oxygen species within the cells[5]. The 72h treatment of HCT116 cells with 200μM 10Panx significantly inhibited cell proliferation[6].
In vivo, 10Panx treatment via intraventricular injection of 5μl (2μg/μl) 0.5 hours before middle cerebral artery occlusion (MCAO) can reduce the infarct volume in rats and alleviate neurological deficits[7]. A single intravenous injection of 2.58nmol/g dose of 10Panx reduced the induced dentin hypersensitivity of the first molar in rats[8].

10Panx是一种强效的Panx1通道抑制剂，靶向Panx1蛋白ECL1结构域中的W74至Y83片段[1]。10Panx 通过抑制Panx1来阻止P2X7受体激活诱导的caspase-1裂解以及IL-1β的加工和释放[2]。10Panx已被广泛用于减轻哮喘小鼠模型中的特征性炎症反应[3]。
在体外，50μM的10Panx处理人真皮淋巴内皮细胞(HDLECs)20小时，显著抑制了毛细管样结构的形成[4]。100μM的10Panx处理牛卵母细胞6小时，会延迟卵母细胞的成熟并降低细胞内的活性氧水平[5]。200μM的10Panx处理HCT116细胞72小时，显著抑制了细胞增殖[6]。
在体内，在大脑中动脉闭塞（MCAO）前0.5小时，脑室内注射5µl（2µg/µl）10Panx，可减少大鼠的梗死体积并减轻神经功能缺损[7]。单次静脉注射2.58nmol/g剂量的 10Panx，可降低大鼠第一磨牙诱导的牙本质敏感[8]。
