Catalog Number: 5003
Chemical Name: D-Tryptophan (2E)-2-(6-quinoxalinylmethylene)hydrazide hydrochloride
Biological Activity
Rho GTPase inhibitor (Kd = 354 nM). Inhibits binding of RhoA to guanine nucleotide exchange factors (GEFs) including LARG, DBL, LBC, p115 RhoGEF and PDZ RhoGEF. Has no effect on the binding of Rac1 or Cdc42 to their respective GEFs. Suppresses RhoA/C-mediated breast cancer cell migration and invasion in vitro. Also induces neurite outgrowth in synergy with NGF.

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?
