生化/生理作用

尼日利亚菌素是一种聚醚离子载体，可催化碱金属（K+）与 H+（反位）的电子中性交换。 尼日利亚菌素跨膜转运单价阳离子具有以下特异性：K+ >Rb+ >Cs+ >>Na+，从而破坏膜电位并刺激线粒体中的 ATPase 活性。
尼日利亚菌素通过促进离子跨膜扩散来杀死细菌。
低浓度（0.5 μM）的尼日利亚菌素会迅速降低 pHi，导致在大脑微血管内皮细胞中刺激 PG 产生 1.5 到 2 倍，并阻止 Erlich 腹水癌细胞中 DNA 的合成。 在脊髓灰质炎病毒进入 Hela 细胞后，用尼日利亚菌素处理可防止脊髓灰质炎病毒对宿主蛋白合成的抑制。 尼日利亚菌素还广泛用于研究可变系统中膜电位变化的后果。

制备说明

Non-canonical inflammasome activation that recognizes intracellular lipopolysaccharide (LPS) causes pyroptosis, the inflammatory death of innate immune cells. The role of pyroptosis in innate immune cells is to rapidly eliminate pathogen-infected cells and limit the replication niche in the host body.
