Catalog Number: 3722
Chemical Name: N-[3-(4-Morpholinyl)propyl]-5,7-diphenylpyrazolo[1,5-a]pyrimidine-3-carboxamide
Biological Activity
Selective inhibitor of multidrug resistance-associated protein 1 (MRP1) and P-glycoprotein (P-gp). Increases the sensitivity of MRP1-overexpressing tumor cells (MCF7/VP) to doxorubicin (Cat. No. 2252), vincristine (Cat. No. 1257) and etoposide (Cat. No. 1226) by 3.8-, 14.6- and 11.6-fold respectively. Increases the efficacy of vincristine and etoposide in murine models of neuroblastoma in vivo. Does not sensitize MRP2, MRP3, MRP4 or MRP5 transporters to known substrates.

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?
