Description: Potent and selective P2X7 antagonist
Chemical Name: N-[1-[[(Cyanoamino)(5-quinolinylamino)methylene]amino]-2,2-dimethylpropyl]-3,4-dimethoxybenzeneacetamide
Purity: ≥97% (HPLC)
Biological Activity for A 740003
A 740003 is a potent and selective P2X7 receptor antagonist (IC50 values are 18 and 40 nM for rat and human receptors respectively). Displays selectivity over a variety of P2X and P2Y receptors up to a concentration of 100 μM. Reduces nociception in animal models of persistent neuropathic and inflammatory pain. Also reduces neuroblastoma tumor growth in mice.
