Catalog Number: 3104
Chemical Name: 6-Amino-8-[(6-iodo-1,3-benzodioxol-5-yl)thio]-N-(1-methylethyl)-9H-purine-9-propanamine
Biological Activity
Potent inhibitor of heat shock protein 90 (Hsp90) (IC50 = 51 nM in MDA-MB-468 cells). Also inhibits cell growth in a range of breast cancer cell lines (IC50 values are 17, 31, 65, 87 and 140 nM for SKBr3, MCF-7, MDA-MB-468, HCC-1806 and MDA-MB-231 cells respectively). Shown to inhibit cell proliferation and induce apoptosis in triple-negative breast cancer (TNBC) cells.

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?
