Redox Biol:HPW-RX40具有作为新型抗血栓药物的潜力

2017-06-20 Emma MedSci原创

PDI(蛋白二硫键异构酶)存在于血小板表面,因其在整合素糖蛋白IIb/IIIa(GPIIb/IIIa)的构象变化和活化中的重要作用而促进血小板聚集。许多研究表明,PDI可作为开发新一类抗血栓药物的潜在靶标。据此,研究人员调查了HPW-RX40对血小板活化和PDI活性的影响。

PDI(蛋白二硫键异构酶)存在于血小板表面,因其在整合素糖蛋白IIb/IIIa(GPIIb/IIIa)的构象变化和活化中的重要作用而促进血小板聚集。许多研究表明,PDI可作为开发新一类抗血栓药物的潜在靶标。据此,研究人员调查了HPW-RX40对血小板活化和PDI活性的影响。

结果显示,HPW-RX40抑制人血小板中的血小板聚集,GPIIb/IIIa活化和P-选择素(血小板选择蛋白)表达。此外,HPW-RX40减少流动条件下人全血中的血栓形成,保护小鼠免受FeCl3诱导的颈动脉闭塞。HPW-RX40抑制重组PDI家族蛋白(PDI,ERp57和ERp5)的活性,并且以可逆的方式抑制血小板的细胞表面PDI活性。外源性添加的PDI能够减弱HPW-RX40对GPIIb/IIIa活化的抑制作用。基于结构的分子对接模拟表明,HPW-RX40通过形成氢键与PDI的活性位点结合。此外,HPW-RX40既不影响细胞活力也不引起人类癌症细胞A549和MDA-MB-231的内质网应激。

研究结果表明,HPW-RX40是具有可逆抗血小板凝集作用的非细胞毒性PDI抑制剂,具有作为新型抗血栓药物的潜力,其中的机制和应用可进行进一步的研究。
