Background

Nigericin sodium salt is an ionophore that exchanges K+ for H+ across biological membranes.

Ionophore is a lipid-soluble molecule that transports ions across the cell membrane.

In medium with Na+, nigericin scarcely affected ADP-induced platelets aggregation, and slightly inhibited thrombin-induced platelets aggregation. Also, nigericin decreased the cytoplasmic pH in the medium with Na+. The effects of nigericin on platelet aggregation are mainly due to its effects on the cytoplasmic pH [1]. The K+ ionophore nigericin is highly effective as an ionophore for Pb2+. Physiological concentrations of Ca2+ or Mg2+ didn’t inhibit nigericin-catalyzed Pb2+ transport, while K+ and Na+ concentrations (0-100 mM) modestly affected Pb2+ transport. Nigericin may be helpful in the treatment of Pb intoxication [2]. At two concentrations representing the low (5uM) and high ATP (1.5mM) ranges, Nigericin inhibited the ATP-driven transhydrogenase reaction at both ranges with a more pronounced effect on the low ATP concentration. At a concentration of 2.5 mM ATP, nigericin tripled the Oxonol response [3].

制备方法

在DMSO中的溶解度<3.7mg/ml。若配制更高浓度的溶液,一般步骤如下:请将试管置于37 °C加热10分钟和/或将其置于超声波浴中震荡一段时间。原液于-20 °C可放置数月。

实验结果

在含K+(与离子载体结合,具有最高渗透性)的培养基中,Nigericin Sodium Salt增强血小板聚集。然而,在含胆碱(与离子载体结合,具有较低的渗透性)的培养基中,Nigericin Sodium Salt抑制血小板聚集。此外,相对于血小板聚集率,Nigericin Sodium Salt对血小板聚集最大值的影响较大。
