What is A-740003?
The Uses of A-740003
A 740003 is a potent, selective and competitive P2X7 receptor antagonist.
What are the applications of Application
A 740003 is a potent, selective and competitive P2X7 receptor antagonist
General Description
A-740003 is a highly affine and selective P2X7 receptor antagonist and is best for the progression of a radiotracer for imaging of neuroinflammation by positron emission tomography.
Biological Activity
Potent, selective and competitive P2X 7 receptor antagonist (IC 50 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 μ M. Reduces nociception in animal models of persistent neuropathic and inflammatory pain.
Biochem/physiol Actions
A-740003 is a selective P2X7 purinoceptor antagonist.
Storage
Store at +4°C
