Potent, selective, competitive human A3 receptor antagonist
Potent, selective, competitive human A3 receptor antagonist (Ki values are 2.3 nM and 10 μM for human and rat A3 receptors, respectively), Antagonises human A1 and A2A receptors. Shows inverse agonist effects in the [35S]GTPγS binding assay. Shows anti-inflammatory effects.
Chemical name(R)-8-Ethyl-3,4,7,8-tetrahydro-4-methyl-2-phenyl-5H-imidazo[2,1-i]purin-5-one hydrochloride
Storage instructionsStore at -20°C. Store at -20°C long term. Store In the Dark. Store under desiccating conditions. This product is air and light sensitive and impurities can occur as a result of air oxidation or due to metabolism by microbes.
Solubility overviewSoluble in DMSO to 25 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
