Catalog Number: 1745
Chemical Name: 5-Iodo-7-β-D-ribofuranosyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine
Biological Activity
Potent adenosine kinase inhibitor (IC50 = 26 nM). Also nucleoside transporter inhibitor (IC50 values are < 25 nM, 7 μM and 15 μM for inhibition of [3H]adenosine, [3H]uridine and [3H]formycin B uptake respectively). Strongly stimulates glycogen synthesis in hepatocytes via activation of glycogen synthase. Also inhibits CK1, insulin receptor tyrosine kinase, phosphorylase kinase, PKA, CK2 and PKC (IC50 values are 0.4, 3.5, 5-10, 5-10, 10.9 and 27.7 μM respectively). Decreases hippocampal DNA methylation through adenosine kinase inhibition in vivo.

Molarity Calculator
Calculate the mass, volume or concentration required for a solution

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)
An example of a molarity calculation using the molarity calculator:
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
