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 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
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]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
