Catalog Number: 1954
Alternate Names: [Arg6,D-Trp7,9,N-MePhe8]-Substance P(6-11)
Biological Activity
Substance P analog that is a broad spectrum neuropeptide antagonist and antiproliferative agent. Blocks Swiss 3T3 cell growth induced by vasopressin, gastrin-releasing peptide and bradykinin. Inhibits neuropeptide-dependent and -independent proliferation of small cell lung cancer in vitro; activates JNK and stimulates apoptosis. Inhibits growth of SCLC xenografts in mice 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?
