Cat.No. 3101 - XRP44X | C21H21ClN4O | CAS No. 729605-21-4
Description: Ras-Net pathway inhibitor
Chemical Name: 1-(3-Chlorophenyl)-4-[(3-methyl-1-phenyl-1H-pyrazol-5-yl)carbonyl]piperazine
Purity: ≥99% (HPLC)

Biological Activity

Ras-Net (Elk-3) pathway inhibitor (IC50 = 10 - 20 nM). Indirectly inhibits Net phosphorylation upstream of Erk1/2 activation. Mediates G2-M cell cycle arrest, suppresses growth of multiple cell types (IC50 ~ 2 nM), inhibits angiogenesis and acts as a microtubule depolymerizing agent in vitro.

Preparing Stock Solutions

The following data is based on the product molecular weight 380.87. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 2.63 mL 13.13 mL 26.26 mL
5 mM 0.53 mL 2.63 mL 5.25 mL
10 mM 0.26 mL 1.31 mL 2.63 mL
50 mM 0.05 mL 0.26 mL 0.53 mL
