Catalog Number: 3253
Chemical Name: (3bS,4aS,5aS,6R,6aR,7aS,7bS,8aS,8bS)-3b,4,4a,6,6a,7a,7b,8b,9,10-Decahydro-6-hydroxy-8b-methyl-6a-(1-methylethyl)trisoxireno[4b,5:6,7:8a,9]phenanthro[1,2-c]furan-1(3H)-one
Biological Activity
Inhibits DNA-dependent ATPase activity of XBP and induces inhibition of RNA polymerase II (RNAPII)-mediated transcription (IC50 = 200 nM). Selective for RNAPII over RNAPI and RNAPIII. Blocks RNA synthesis in HeLa cells (IC50 = 62 nM); exhibits potent antiproliferative activity in 60 cancer cell lines (average IC50 = 12 nM) and induces apoptosis by blocking TNF-α-mediated c-IAP1 and c-IAP2 induction. Also displays immunosuppressive and anti-inflammatory activity.

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?
