一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
Probenecid是有机阴离子运输和多药耐药相关蛋白(MRP)的抑制剂[1,2]。Probenecid也可抑制pannexin-1通道,IC50值150 μM[3]。
MRPs是转运不同的分子穿过细胞膜的ATP结合带(ABC)转运者,并具有耐多药性。
Probenecid是有机阴离子运输、MRP和pannexin-1渠道的抑制剂。在MRP-过表达的HL60/AR和H69/AR肿瘤细胞系中,Probenecid以浓度依赖的方法逆转对道诺霉素(DNR)和长春新碱(VCR)的抗性[1]。在野生型AML-2细胞中,Probenecid以剂量和时间依赖的方式增加了MRP水平。在MRP-过表达的AML细胞中,Probenecid表现出显著的化学敏感效应。这些结果表明,Probenecid是一个有效的肿瘤细胞多药耐性(MDR)的化学敏感剂,也是MRP的激活剂[2]。
在缺血/再灌注(I/R)损伤大鼠中,Probenecid可防止CA1神经细胞死亡。Probenecid加强HSP70的上调,抑制Calpain-1的表达和组织蛋白酶B的释放。Probenecid也可抑制星形胶质细胞和小胶质细胞的增殖[4]。

Cell experiment:[1] | |
Cell lines | Wild-type and multidrug resistance protein (MRP)-overexpressing acute myelogenous leukemia (AML) cells, namely AML-2/WT and AML-2/DX100 |
Reaction Conditions | 100, 200, 400 and 600 μM probenecid for 6 ~ 48 h incubation |
Applications | Probenecid increased the MRP levels without an increase in MRP mRNA in AML-2/WT in both a time- and dose-dependent manner. Probenecid showed a marked chemosensitizing effect in AML-2/DX100. |
Animal experiment:[2] | |
Animal models | Male Sprague-Dawley rats subjected to 20-min global cerebral ischemia/reperfusion (I/R) injury |
Dosage form | 0.1, 1 or 10 mg/kg (intravenously); 2 mg/kg (intraperitoneally); 5 mg/kg (orally) Administered intravenously, intraperitoneally, or by gavage before or after reperfusion |
Applications | Probenecid via all three routes protected against CA1 neuronal death when given before reperfusion. This protective effect continued when probenecid was given at 2 h after reperfusion, but not at 6 h. Interestingly, the protective effect regained if probenecid was given continuously for 7 days after reperfusion. Probenecid protected against transient global cerebral I/R injury by inhibiting calpain-cathepsin pathway and the inflammatory reaction. |
