Biological Activity

Potent and selective A1 receptor antagonist/inverse agonist. Exhibits high binding affinity at A1 receptor (Ki values are 0.07 and 0.96 nM for rat and human receptors respectively). Reduces basal [35S]-GTPγS binding 44.6% (IC50 = 0.19 nM). Antagonizes the effects of A1 agonist R-PIA (IC50 = 18.3 nM) and exhibits competitive antagonism on CCPA-induced tracheal contractions ex vivo. Displays 217- fold selectively over hA2A receptor and >1000-fold selectivity over hA3 receptor.

Preparing Stock Solutions

The following data is based on the product molecular weight 350.39. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 2.85 mL 14.27 mL 28.54 mL
5 mM 0.57 mL 2.85 mL 5.71 mL
10 mM 0.29 mL 1.43 mL 2.85 mL
50 mM 0.06 mL 0.29 mL 0.57 mL
