Saline
30.0mg/ml Taking the 1 mL working solution as an example, add 30 mg of this product to 1 ml of physiological saline (0.9% NaCL solution), mix evenly to make it clear, The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description A-438079 HCl is a potent, and selective P2X7 receptor antagonist with pIC50 of 6.9.
Targets
P2X7 [1]
(in 1321N1 cells)
6.9(pIC50)
In vitro In 1321N1 cells stably expressing rat P2X7 receptors, A-438079 blocks BzATP-(10 μM) evoked changes in intracellular calcium concentrations with an IC50 of 321 nM. A-438079 is also selective for the P2X7 receptor, at concentrations up to 100 μM.[1]
In vivo Intraperitoneal injection of A-438079 (5 and 15 mg/kg) 60 min after triggering seizures reduces seizure severity and neuronal death within the hippocampus. A-438079 has superior neuroprotective effects compared with an equally dose of phenobarbital (25 mg/kg).[2] A-438079 partially but significantly prevents the 6-OHDA-induced depletion of striatal DA stores.[3] Pretreatment with A-438079 reduces nociceptive behaviour scores in the HC model.[4] A-438079 (80 μmol/kg, i.v.) reduces noxious and innocuous evoked activity of different classes of spinal neurons in neuropathic rats. A-438079 (100 and 300 μmol/kg, i.p.) significantly raises withdrawal thresh-olds in both the SNL and CCI models.[1]
