Brilliant Blue G is also a selective inhibitor of the P2X purinoceptor channel P2X7 [1].
P2X receptors are membrane ion channels activated in response to the binding of extracellular ATP. Seven P2X subtypes have been identified. P2X receptors have been involved in in diverse patho- and physiological processes, such as the autonomic nervous system, afferent signalling, chronic pain, and in autocrine loops of endothelial and epithelial cells. The P2X7 receptor plays a prominent role in certain neurologic disorders, such as ischemia-reperfusion injury, Alzheimer's disease, spinal cord injury and sensory neuropathies [2].
In HEK293 cells heterologously expressing human P2X7 receptors, Brilliant Blue G noncompetitively inhibited rat and human P2X7 receptors with IC50 values of 10 and 200 nM, respectively. The IC50 values for inhibition of the other P2X receptors ranged from 2 to >30 μM; Brilliant Blue G inhibited the rat and human P2X4 receptors with the IC50 values of >10 and 3.2 μM [1]. Subretinal injection of BBG caused retinal cell degeneration at lower concentrations. Subretinal injection of BBG (0.25 mg/mL) provided satisfactory biocompatibility [3].
