In vitro | Evans Blue is found to be inhibiting DNA binding of NF-κB at a low concentration of 100 μM[1]. It has proven over the years to be a dependable stain for microscopic determination of cell death[2]. Evans Blue is also a known blocker of a subset of a-amino-3-hydroxy-5-methyl-isoxazole/kainate receptors (IC50=355 nM) for the subunit combination GluR1,2[5]. Evans blue is the first known δ-subunit-specific antagonist of ENaC and activates large-conductance Ca2+-activated K+ channels in sheep bladder myocytes and cultured endothelial cells of human umbilical veins[5]. |
In vivo | Evans blue pretreatment could inhibit the mast cells degranulation and that may be the main mechanism for prevent animals from C48/80-triggered anaphylaxis and systemic inflammation[4]. Evans blue modulates the non-N-methyl-d-aspartate receptor in rat thalamic neurons, blocks the P2X-purinergic receptor in rat vas deferens, and inhibits the glutamate transporter in rat brain synaptic vesicles[6]. |
